Novel aluminum electrolysis cell anode conductive metal device

Abstract

A novel aluminum electrolysis cell anode conductive metal device is formed by combining an anode aluminum guide rod, an anode conductive stand column plate and an anode conductive cross beam, that is, the upper part of the anode conductive cross beam is in conductive structure connection with the aluminum guide rod through the anode conductive stand column plate. In the production process of electrolytic aluminum, after the anode conductive cross beam is directly mounted and constructed in the anode conductive concave groove in the upper part of the anode carbon block, direct iron-carbon bonding interface conductive connection is generated between the anode conductive cross beam and the anode carbon block; therefore, the anode current of the anode large bus of the aluminum electrolysis cell is directly conducted and conveyed to the anode carbon block. In the production process of electrolytic aluminum, the anode metal conductive device disclosed by the invention can be used for canceling and replacing the production process of an anode carbon block steel claw group which is used for pouring phosphorus pig iron by using an anode steel claw in the prior art and simplifying the process flow of anode assembly; and moreover, the direct-current power consumption of the electrolytic aluminum can be greatly reduced, and energy-saving, emission-reducing and low-carbon production of the electrolytic aluminum is realized.

Description

[0001] Technical Field: A new type of anode conductive metal device for aluminum electrolytic cells is mainly applied to the production of aluminum electrolytic cells and the assembly structure of the anode conductive metal device for aluminum electrolytic cells.

[0002] Background Art: The currently common anode conductive metal device for aluminum electrolytic cells is mainly composed of an aluminum conductor rod, an aluminum-steel composite explosion-bonded sheet, and an anode steel claw assembly structure. During the production of electrolytic aluminum, this anode conductive metal device is assembled with an anode carbon block having a circular carbon bowl provided in a boss to form a complete anode conductive device. An important technical feature of the prior art is that when the anode steel claw of the anode conductive metal device is integrally assembled with the anode carbon block, first, the anode steel claw head is inserted into the anode carbon bowl at the upper part of the anode carbon block, and then molten phosphorus cast iron is poured into the annular groove in the space between the anode steel claw head and the circular anode carbon bowl. After cooling, a "phosphorus iron ring" is formed between the anode steel claw head and the anode carbon bowl, which is a component that conducts electricity and structurally connects the anode steel claw and the anode carbon block. That is, the phosphorus iron ring is used as an intermediate connecting component between the anode steel claw head and the anode carbon block to construct a complete anode carbon block steel claw group. Then, the anode carbon block steel claw group is installed and fixed on the anode busbar of the aluminum electrolytic cell with a small box fixture, and the anode current passes through this anode conductive metal device and the anode carbon block to participate in the electrolytic thermoelectric chemical reaction.

[0003] The production process of electrolytic aluminum is a production process that consumes anode carbon blocks. When the anode is consumed to the stage of residual anode, the residual carbon block and the upper anode conductive metal device need to be removed from the electrolytic cell, and the residual carbon block and the phosphorus iron ring are unloaded from the anode steel claw by mechanical pressing to remove the anode conductive metal device, and then a new anode carbon block is poured to form a new anode carbon block steel claw group for cyclic turnover use.

[0004] The existing anode conductive metal device configured with anode steel claws mainly has the following technical defects: First, when assembling the anode carbon block and the anode steel claw head, the method of hot-casting a phosphorus iron ring in the anode carbon bowl of the circular boss is used to conductively connect the anode carbon block and the anode steel claw. This not only wastes the heating electric energy consumption of phosphorus cast iron but also increases a transition layer with a relatively high resistance value, namely the phosphorus iron ring, between the anode steel claw head and the anode carbon bowl, resulting in a relatively high overall voltage drop of the anode conductive device. This causes about 350 kAW of current consumption per ton of electrolytic aluminum, resulting in a relatively low overall current efficiency of the aluminum electrolytic cell. Second, when assembling the anode conductive metal device and the anode carbon block and separating and pressing off the residual carbon block from the anode steel claw, not only a large amount of alternating current consumption is required, but also a large number of pressing-off, assembling, and lifting and transportation equipment need to be configured and invested, resulting in a relatively large investment and occupancy cost in the production of electrolytic aluminum.

[0005] In order to reduce the DC power consumption in aluminum electrolysis production and the AC power consumption in anode assembly, achieve energy conservation, emission reduction and low-carbon production in aluminum electrolysis, and reduce the production process cost of aluminum electrolysis, engineering and technical personnel in the domestic and foreign aluminum electrolysis industries have been conducting scientific and technological research on the common core technical problems existing in the aluminum electrolysis industry, such as the high structural voltage drop and large resistance value, complex production process, and high process cost, which are caused by the production process of using anode steel claws and casting phosphor iron in the anode carbon bowl to construct the anode assembly of anode carbon blocks. They have been trying to achieve the goal of reducing the energy consumption in aluminum electrolysis production through technological innovation. However, so far, there has been no breakthrough progress and reports on industrial applications. Therefore, the present invention proposes a technical solution for a novel anode conductive metal device for an aluminum electrolysis cell.

[0006] SUMMARY OF THE INVENTION: The innovative points of the anode conductive metal device for an aluminum electrolysis cell described in the present invention include the following. First, the anode conductive metal device is constructed by welding and combining an aluminum conductor rod, an aluminum-steel composite explosion-bonded sheet, an anode conductive column or an anode conductive plate, and an anode conductive crossbeam. Second, an anode conductive concave groove constructed on the upper part of the anode carbon block is used to replace the anode carbon bowl provided on the upper part of the anode carbon block in the prior art. Third, an anode conductive column or an anode conductive plate is used to replace the anode steel claw crossbeam and the anode steel claw head provided at the bottom of the aluminum conductor rod and the aluminum-steel composite explosion-bonded sheet in the prior art. Fourth, the anode conductive crossbeam can be used to replace the conductive connection medium, the phosphor iron ring, constructed between the anode steel claw head and the anode carbon bowl in the prior art. Fifth, a production method of directly adopting an insertion and inlay cold-state combination process at normal temperature to insert the anode conductive crossbeam into the conductive concave groove of the electrode to achieve the conductive structure connection between the anode conductive metal device and the anode carbon block is used to replace the hot-state connection production method in the prior art, in which after the anode steel claw head is inserted into the anode carbon bowl, high-temperature phosphor iron molten metal is cast in the anode carbon bowl to generate a phosphor iron ring to assemble and construct the anode conductive metal device and the anode carbon block.

[0007] According to the above technical solution, a novel anode conductive metal device of the present invention is composed of a positive aluminum guide rod, an anode conductive column plate, and an anode conductive cross beam. That is, the upper part of the anode conductive cross beam is conductively connected to the aluminum guide rod by welding through the anode conductive column plate. After the anode conductive cross beam is directly installed in the anode conductive concave groove on the upper part of the anode carbon block, a direct iron-carbon bonding interface conductive connection can be generated between the anode conductive cross beam and the anode carbon block, so as to realize the function of directly conducting and transporting the anode current of the anode busbar of the aluminum electrolytic cell to the anode carbon block. That is, instead of conducting connection through the existing transition conductive medium of the ferrophosphorus ring, a direct iron-carbon conductive connection is achieved through the anode conductive cross beam and the anode carbon. In order to improve and optimize the strength of the conductive connection and structural connection between the anode conductive column plate and the anode conductive cross beam, an anode conductive connection strengthening vertical plate or an anode conductive connection strengthening flat plate is provided on the upper part of the anode conductive cross beam and the side part of the anode conductive column plate.

[0008] According to the above technical solution, for a novel anode conductive metal device of the present invention, the cross-sectional structure size of the anode conductive cross beam is correspondingly configured with the cross-sectional structure size of the anode conductive concave groove on the upper part of the anode carbon block. The dimensional deviation of the assembly gap between the two should be less than or equal to the thermal expansion dimensional deviation formed due to the different thermal expansion coefficients of the metal material of the anode conductive cross beam and the carbon material of the anode carbon block under the technical conditions of the electrolysis thermal working condition, so as to enable a tight conductive structure connection at the iron-carbon bonding interface between the anode conductive cross beam and the anode carbon block.

[0009] According to the above technical solution, for a novel anode conductive metal device of the present invention, the cross-sectional shape of the anode conductive cross beam should be rectangular, or trapezoidal, or a rectangle with a mortise and tenon connection boss on the side elevation. To improve and optimize the conductive connection structure strength of the anode conductive cross beam, a biting tooth groove is constructed on the side surface of the rectangular anode carbon block. The length of the anode conductive cross beam is greater than the length of the anode conductive column plate, and after the two are constructed, their side projections are in a boss shape.

[0010] According to the above technical solution, for a novel anode conductive metal device of the present invention, when one anode conductive cross beam is connected and configured with the anode conductive concave groove, one anode conductive column plate is provided on the upper part of the anode conductive cross beam for conductive structure connection with the aluminum guide rod.

[0011] According to the above technical solution, for a novel anode conductive metal device of the present invention, when two symmetrically arranged anode conductive cross beams are connected and configured with an anode conductive concave groove on the upper part of the anode carbon block, on the upper parts of the two symmetrically arranged anode conductive cross beams, they are respectively conductively connected to two symmetrically arranged anode conductive column plates and an aluminum guide rod with a horizontal structure gap adjustment seam provided at the lower end.

[0012] According to the above technical solution, for a novel anode conductive metal device of the present invention, when two symmetrically arranged anode conductive crossbeams are used for conductive connection and configuration with two symmetrically arranged anode conductive concave grooves on both sides of the anode conductive bosses on the upper part of the anode carbon block, on the upper parts of the two symmetrically arranged anode conductive crossbeams, they are respectively conductively connected to two symmetrically arranged anode conductive column plates on the left and right and an aluminum guide rod with a horizontal structure gap adjustment seam arranged at the lower end; that is, two symmetrically arranged anode conductive column plates, two anode conductive crossbeams and an aluminum guide rod are combined to form an anode conductive metal device.

[0012] According to the above technical solution, for a novel anode conductive metal device of the present invention, at the center line of the lower end of the aluminum guide rod, there is an anode horizontal structure gap adjustment seam for adjusting the width of the horizontal displacement dimension of two symmetrically arranged anode conductive crossbeams; at the lower ends of the two symmetrically designed anode conductive crossbeams, anode conductive column plates and the aluminum guide rod, there is an anode structure gap seam adjustment device for adjusting the width of the anode horizontal structure gap adjustment seam, that is, for adjusting the horizontal displacement gap of the anode conductive crossbeam. This anode structure gap seam adjustment device can be configured as a screw type adjustment device or an inclined iron type adjustment device. By dynamically adjusting the anode structure gap seam adjustment device arranged above the anode conductive crossbeam and on the side of the anode conductive column, that is, the screw type adjustment device or the inclined iron type adjustment device; not only can the clamping strength between the anode conductive crossbeam and the anode conductive boss or the side wall of the anode conductive concave groove on the upper part of the carbon block be adjusted, but also the fitting density of the iron-carbon bonding interface between the anode conductive crossbeam and the anode carbon block can be adjusted.

[0013] According to the above technical solution, the anode conductive crossbeam (1) of the present invention is a combined connecting member and a conductive connecting component for iron-carbon connection between the anode conductive metal device arranged below the anode conductive column and the anode carbon block. Under the technical conditions of the thermal load working condition during the electrolysis production process, the material characteristic that the thermal expansion rate of the metal material is greater than that of the anode carbon material can be utilized to make the side surfaces of the anode conductive crossbeam (1) and the anode conductive concave groove (7) or the anode conductive convex platform (8) on the upper part of the anode carbon block generate a dense and tight interfacial conductive connection. Therefore, when designing the cross-section of the anode conductive crossbeam, the width of the anode conductive crossbeam (1) is also greater than the height of the anode conductive crossbeam (1), that is, the conductive area of the anode conductive crossbeam (1) is greater than the conductive areas of the anode steel claw crossbeam and the ferrophosphorus ring in the prior art; if understood from the planar projection of the anode conductive device, it is equivalent to directly embedding and installing the anode steel claw crossbeam of the prior art after moving it down into the anode conductive concave groove (7) on the top of the anode carbon block. The width dimension of the rectangular cross-section of the anode conductive crossbeam should be greater than its height dimension; when designing the width of the anode conductive crossbeam, it should be ensured that the maximum conductive metal area of the anode conductive crossbeam is limited under the condition that no thermal stress damage cracks occur in the side convex platform of the anode carbon block concave groove on the upper part of the anode carbon block under the thermal load working condition.

[0014] According to the above technical solution, for the novel anode conductive metal device of the present invention, when configuring the structural connection with the anode carbon block, two symmetrically arranged anode conductive crossbeams (1) can be provided at the lower part of an aluminum busbar (5) to be structurally connected with two paired anode conductive concave grooves (7) on the outer sides of the anode conductive convex platforms on the upper part of the anode carbon block. A horizontal structural gap adjustment seam (9) is provided at the middle part of the symmetrically arranged anode conductive columns or anode electric vertical plates on the upper parts of the two symmetric anode conductive crossbeams (1); in order to improve the structural connection strength between the anode conductive column and the anode conductive crossbeam (1) and optimize its conductive connection performance, an anode structural gap seam adjustment device (10) is provided at the connection between the anode conductive column or the anode conductive column plate and the anode conductive crossbeam (1), and this device can be designed as a screw-type adjustment device or a wedge-type adjustment device.

[0015] In the process of electrolytic aluminum production, by adopting the anode conductive metal device of the present invention in an aluminum electrolytic cell, compared with the prior art, the following remarkable technical progress effects can be achieved. First, using the anode conductive crossbeam (1) to replace the existing ferrophosphorus ring can not only reduce the voltage drop resistance of the iron-carbon contact component and thus reduce the DC power consumption in the production of electrolytic aluminum, but also change its assembly process and reduce the assembly cost of the anode conductive device. Second, using the anode conductive crossbeam (1) to replace the ferrophosphorus ring can not only reduce the resistance value of its conductive material by improving the conductive performance of the anode conductive metal material, but also provide an innovative space for the improvement of its conductive structure. Third, using the anode conductive column to replace the anode steel claw and the anode steel claw head can not only reduce the manufacturing cost of the structure of the anode conductive device, but also extend the service life of the anode conductive device, prevent the thermal stress deformation of the anode conductive device, and improve the conductive quality of the anode conductive device. Fourth, adopting the cold-state combined assembly process for the anode conductive device to replace the hot-state combined assembly production process in the prior art can not only reduce the process power consumption of anode assembly, but also reduce its assembly process cost and equipment investment cost.

[0029] Specific implementation manner: The technical features and technical solutions of an anode conductive metal device for an aluminum electrolytic cell according to the present invention can be made clearer through the description in the accompanying drawings of the specification and specific embodiments.

[0030] In Embodiment 1, as Figure 1 Figure 2 shown, an anode conductive metal device for an aluminum electrolytic cell according to the present invention is welded and combined by an aluminum guide rod (5), an aluminum-steel composite explosion-bonded sheet (4), an anode conductive column (2), and an anode conductive crossbeam (1). An anode conductive reinforcement connection plate (3), namely an anode conductive reinforcement connection vertical plate (3-1), is provided on the upper part of the anode conductive crossbeam (1) and the side part of the anode conductive column (2). The anode conductive crossbeam (1) is assembled in the anode conductive concave groove (7) on the top of the anode carbon block (6) and is a component for directly connecting the iron-carbon structure and conducting electricity of the anode conductive device.

[0031] As Figure 1 Figure 2As shown in the figure, the anode conductive metal device described in Embodiment 1 is constructed by a rectangular anode conductive crossbeam (1) welded to an aluminum guide rod and the lower part of the anode conductive column. The horizontal projection of the cross-section of the anode conductive column (2) is rectangular. Anode conductive connection reinforcing vertical plates (3-1) are constructed on both sides of the anode conductive column (2) and the upper part of the anode conductive crossbeam (1). In the actual implementation process, the horizontal projection of the cross-section of the anode conductive column (2) can also be circular, that is, a round steel bar is used to replace the rectangular steel bar.

[0032] Embodiment 2, as Figure 3 Figure 4 As shown in the figure, the structure and principle of Embodiment 2 are basically the same as those of Embodiment 1. This anode conductive metal device is also composed of an aluminum guide explosive welding sheet, anode conductive column (2), and anode conductive crossbeam (1) combined and constructed; its distinguishing technical feature is that the side cross-section shape of the anode conductive crossbeam (1) is a rectangular anode conductive crossbeam (1) with a tenon and mortise connecting convex platform on the side corresponding to the anode conductive concave groove. When assembling with the anode carbon block, the anode conductive device is horizontally displaced from the side end of the anode carbon block, and the anode conductive crossbeam (1) with a tenon and mortise connecting piece on the side, as well as the overall anode conductive metal structure constructed by the anode conductive column (2) and aluminum guide rod on its upper part, are directly pushed and extruded into the anode conductive concave groove (7) with a tenon and mortise connecting concave groove of the anode carbon block. In the implementation process of the technical solution of the present invention, the width of the anode conductive crossbeam (1) is greater than the height of the anode conductive crossbeam (1), and the total sum of the conductive output areas of the anode conductive crossbeam (1) is greater than the conductive area of the anode steel claw crossbeam of the existing anode conductive device, that is, the conductive output area of the anode steel claw crossbeam.

[0034] Embodiment 3, as Figure 5 Figure 6 As shown in the figure, the structure and principle of Embodiment 3 are basically the same as those of Embodiment 2. This anode conductive metal device is also composed of an aluminum guide explosive welding sheet, anode conductive column (2), and anode conductive crossbeam (1) combined and constructed; its distinguishing technical feature is that the side cross-section shape of the anode conductive crossbeam (1) is a trapezoidal anode conductive crossbeam (1). When assembling with the anode carbon block, the trapezoidal anode conductive crossbeam (1) on the side cross-section shape, as well as the overall anode conductive metal device constructed by the anode conductive column (2) and aluminum guide rod on its upper part, are horizontally displaced from the side end of the anode carbon block and directly pushed and extruded into the anode conductive concave groove (7) with a tenon and mortise connecting concave groove on the upper part of the anode carbon block.

[0035] As described in Embodiment 2 and Embodiment 3, during the implementation of the technical solution of the present invention, the cross-section of its anode conductive crossbeam (1) is designed to have a mortise-and-tenon structure configuration and a trapezoidal shape. The purpose is to enable the anode conductive crossbeam (1), after being combined and configured with the anode conductive boss (8) of the anode carbon block, to make the anode conductive metal device and the anode carbon block produce a mortise-and-tenon type of hook connection; and thereby increase the structural strength of the connection structure between the anode conductive metal device and the anode carbon block, prevent the occurrence of vertical displacement between the anode carbon block and the anode conductive crossbeam (1), and avoid the occurrence of the accident of the anode carbon block falling off.

[0035] As described in Embodiment 1, Embodiment 2 and Embodiment 3, when the anode conductive crossbeam (1) and the anode carbon block of the present invention are assembled and configured, compared with the existing structure of using anode steel claws and anode carbon blocks with cast phosphor iron, one of the most distinctive technical features is that it adopts a cold assembly process similar to the assembly of mechanical parts. And the anode conductive crossbeam (1) is an anode metal conductive component. The resistivity of the conductive performance, that is, the conductive effect, between the iron-carbon bonding contact surface of this anode metal conductive component and the anode conductive concave groove should be as low as possible. That is, the tighter and denser the fit of the iron-carbon bonding interface, the better. Therefore, when designing the dimensional deviation of the assembly structure of the anode conductive crossbeam (1) and the anode conductive concave groove (7), the deviation value of the assembly gap between the two should be less than the dimensional deviation value generated by the thermal expansion stress coefficients in the width direction of the metal material of the anode conductive crossbeam (1) and the width direction of the carbon material of the anode carbon block. So as to make a dense conductive connection between the fitting interfaces of the anode conductive crossbeam (1) and the anode carbon block under the electrolytic heat load state. In order to achieve the technical goal that the innovative structure of the anode conductive device is superior to the traditional anode conductive device.

[0042] Embodiment 4 is as Figure 7 Figure 8As shown in the figure; the anode conductive metal device described in this embodiment is composed of an aluminum busbar, an explosion-bonded sheet, an anode conductive column (2) plate, an anode conductive connection reinforcing plate, and an anode conductive crossbeam (1). Its technical features are as follows: a horizontal structural gap adjustment slit (9) is provided at the lower part of the aluminum busbar, so that the explosion-bonded sheet, the anode conductive column (2), the anode conductive connection reinforcing plate, and the anode conductive crossbeam (1) can be divided into two components that are symmetric with each other about the height center line. When combined and installed with the anode carbon block, two anode conductive crossbeams (1) with equal height positions and symmetric left and right can be assembled in the anode conductive concave groove (7) at the upper part of an anode carbon block. Then, the anode structural gap slit adjustment device (10), that is, the wedge iron type adjustment device (10-2), is inserted into the horizontal structural gap adjustment slit (9) at the middle position between the two symmetric left and right anode conductive crossbeams (1) or anode conductive connection reinforcing plates (3) or anode conductive crossbeams (1), and is squeezed downward into the horizontal structural gap adjustment slit (9) in a mechanical interference manner, so as to squeeze the two symmetric left and right anode conductive crossbeams (1) in the lateral horizontal direction, causing the anode conductive crossbeam (1) to expand laterally, so that a firm structural connection and a tight iron-carbon interface conductive connection are generated between the outer side of the anode conductive crossbeam (1) and the inner side wall of the anode conductive concave groove. In order to improve and optimize the bonding connection strength between the two, a biting tooth groove (12) is provided on the contact surface between the side of the anode conductive crossbeam (1) and the anode carbon block. The cross-sectional shape of the biting tooth groove (12) is similar to a serrated thread groove. The cross-section of the anode conductive crossbeam (1) described in this embodiment can also be a long trapezoid or a rectangular long strip member with a tenon and mortise connecting member hanging member (11). As shown in Embodiment 2 and Embodiment 3 of the figure Figure 4 and Figure 6 shown

[0043] Embodiment 5 is as Figure 9 Figure 10As shown in the figure; the anode conductive metal device described in this embodiment is basically the same as that in Embodiment 4. This anode conductive metal device is composed of an aluminum guide rod, an explosion welding sheet, an anode conductive column (2) plate, an anode conductive connection reinforcing plate, and an anode conductive cross beam (1). A horizontal structure gap adjustment slit (9) is also provided at the lower part of the aluminum guide rod, so that the explosion welding sheet, the anode conductive column (2), the anode conductive connection reinforcing plate, and the anode conductive cross beam (1) can be divided into two parts that are symmetric with each other about the height center line and are installed on both sides of the lower part of an anode aluminum guide rod with a horizontal width adjustment slit at the lower end. The first distinguishing technical feature is that: on the upper part of the two symmetric anode conductive cross beams (1) and at the bottom of the anode conductive column (2) plate, an anode conductive connection reinforcing flat plate (3-2) and an anode conductive connection reinforcing vertical plate (3-1) are provided, and on the anode conductive connection reinforcing vertical plate (3-1), there is provided an anode structure gap slit adjustment device (10) for adjusting the width of the horizontal structure gap adjustment slit (9) provided in the middle of the width center line of the anode conductive device and capable of adjusting the clamping force of the two symmetric anode conductive cross beams (1) on the anode conductive boss (8), that is, a screw type adjustment device (10-1); so that during the anode assembly process in electrolytic production, after the two anode conductive cross beams (1) are installed by inlaying from the upper part of the anode carbon block into the anode conductive concave grooves (7) on both sides of the anode conductive boss (8) in the middle of the anode carbon block. Then, the screw type adjustment device (10-1) is used for rotational clamping adjustment, so that the anode conductive cross beam (1) can implement a high-strength clamping structure connection and a tight conductive connection to the anode conductive boss (8). And due to the thermal expansion stress and the increase in size of the anode conductive cross beam (1) under the thermal load state of the aluminum electrolytic cell, a tighter conductive connection is generated at the iron-carbon contact interface between the anode conductive cross beam (1) and the anode conductive concave groove (7).

[0043] Embodiment 6 is as follows Figure 11 Figure 12 As shown in the figure; the anode conductive metal device described in this embodiment is basically the same as that in Embodiment 5. The first distinguishing technical feature is that: the anode conductive column (2) provided on the upper part of the two symmetric anode conductive cross beams (1) is changed to an anode conductive column (2) plate structure configuration, and the anode conductive reinforcing connection vertical plate and the anode conductive column (2) plate are changed to an integrated structure design, that is, it is changed to a convex platform thick plate structure design with a convex shape in the side projection. The second distinguishing technical feature is that on the combined assembly of the two symmetrically arranged anode conductive column (2) plates and the anode conductive connection reinforcing vertical plates (3-1) on both sides, there is provided a screw type adjustment device (10-1) that can be used to adjust the clamping force of the anode conductive cross beam (1) installed symmetrically on the left and right in the anode conductive concave groove (7) on the anode conductive boss (8) and to adjust the installation width dimension. The usage and function of this screw type adjustment device (10-1) are the same as those in Embodiment 5.
