Description

[Technical Field]

[0001] The present invention relates to a belt-type continuous casting method and a casting apparatus. [Background technology]

[0002] As an example of a belt-type continuous casting method, Patent Document 1 describes a casting method in which molten metal is supplied into a mold formed by a pair of casting belts to continuously produce thin plate-shaped cast pieces. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 9-192789 Summary of the Invention [Problem to be solved by the invention]

[0004] In the belt-type continuous casting method, temperature control of the casting belt is important. By controlling the temperature of the casting belt to an appropriate value, the temperature of the casting material fed into the mold can be increased, which reduces casting defects (blowholes) in the cast bar, leading to improved quality in the next process.

[0005] However, in current belt-type continuous casting machines, the temperature of the casting belt is only measured intermittently by an operator, and the heater that heats the casting belt and the band jetter for cleaning are also adjusted manually by the operator.

[0006] In addition, although the belt-type continuous casting method described in Patent Document 1 describes that a temperature sensor is provided to measure the temperature of the casting belt during casting, it does not specifically mention how to control or manage the temperature of the casting belt.

[0007] SUMMARY OF THE INVENTION An object of the present invention is to provide a belt-type continuous casting method and casting apparatus that can improve the quality of the cast bar in the process following the casting process. [Means for solving the problem]

[0008] The belt-type continuous casting method of the present invention is a belt-type continuous casting method in which molten metal is poured into a space formed by a casting ring rotating around a rotation axis and a circulating casting belt to continuously cast cast bars. The method comprises the steps of: pouring molten metal into the space formed by bringing the casting belt into close contact with the rotating casting ring to continuously cast cast bars; separating the casting belt from the rotating casting ring to send the cast bars out of the casting section; cleaning the casting belt; heating the casting belt; and measuring the temperature of the casting belt. The degree of cleaning and heating of the casting belt is automatically adjusted based on the results of measuring the temperature of the casting belt.

[0009] In one aspect of the present invention, the method further includes a release agent application step of applying a release agent to the casting belt, measuring the temperature of the casting belt in the direction of travel of the casting belt before applying the release agent, and applying the release agent to the casting belt immediately before feeding the casting belt to the casting ring after measuring the temperature.

[0010] In another aspect of the present invention, the heating of the casting belt in the heating step is carried out in the direction of travel of the casting belt before the application of the release agent, and the temperature of the casting belt is measured between the heating step and the release agent application step.

[0011] The belt-type continuous casting apparatus of the present invention is a belt-type continuous casting apparatus comprising a casting ring that rotates around a rotation axis and a circulating casting belt, and in which molten metal is poured into a space formed by the casting ring and the casting belt to continuously cast cast bars. The apparatus comprises a casting section that continuously casts cast bars by pouring molten metal into the space formed by bringing the casting belt into close contact with the rotating casting ring, a cleaning section that cleans the casting belt, a heating section that heats the casting belt, a temperature measurement section that measures the temperature of the casting belt, and a control section that adjusts the degree of cleaning and heating of the casting belt. After casting the cast bar, the casting section separates the casting belt from the rotating casting ring and sends the cast bar out of the casting section, and the control section adjusts the degree of cleaning and heating of the casting belt based on the results of the temperature measurement of the casting belt by the temperature measurement section.

[0012] In one aspect of the present invention, the casting machine further includes a release agent applicator that applies a release agent to the casting belt, the release agent applicator being provided in a position in the direction of travel of the casting belt immediately before the casting belt is supplied to the casting ring, the heating unit being provided upstream of the release agent applicator, and the temperature measuring unit being provided between the heating unit and the release agent applicator. [Effects of the Invention]

[0013] According to the present invention, it is possible to improve the quality of the casting material in the process subsequent to the casting process. [Brief explanation of the drawings]

[0014] [Figure 1] 1 is a schematic view of a belt-type continuous casting device according to an embodiment of the present invention. [Figure 2] FIG. 2 is a cross-sectional view showing the structure cut along the line AA in FIG. [Figure 3] 2 is an enlarged schematic view showing the detailed structure of a casting unit of the belt-type continuous casting machine shown in FIG. 1. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, embodiments will be described in detail with reference to the drawings. In all drawings for explaining the embodiments, components having the same functions are designated by the same reference numerals, and repeated explanations thereof will be omitted. In the following embodiments, explanations of the same or similar parts will not be repeated unless particularly necessary.

[0016] <Structure of a belt-type continuous casting machine> The structure of the belt-type continuous casting apparatus of this embodiment will be described below with reference to FIGS.

[0017] As shown in FIG. 1, the belt-type continuous casting apparatus 13 according to this embodiment is an apparatus for continuously casting copper wire (copper wire rod), and includes, for example, a melting furnace 210, an upper trough 220, a holding furnace 230, an adding section 240, a lower trough 260, a tundish 300, a molten metal pouring nozzle 320, a continuous casting machine (casting section) 500, a hot rolling machine 620, and a winding machine (coiler) 640.

[0018] The melting furnace 210 heats and melts copper raw material to produce molten copper (molten metal) 110, and includes, for example, a furnace body and a burner provided at the bottom of the furnace body. The copper raw material is charged into the furnace body and heated by the burner, thereby continuously producing molten copper 110. For example, copper (Cu) or the like can be used as the copper material. The molten copper contains oxygen (O).

[0019] The upper trough 220 is provided downstream of the melting furnace 210, connects the melting furnace 210 and the holding furnace 230, and transports the molten copper 110 produced in the melting furnace 210 to the holding furnace 230 downstream.

[0020] The holding furnace 230 is provided downstream of the upper trough 220 and heats the molten copper 110 transferred from the upper trough 220 to a predetermined temperature and temporarily stores the molten copper 110. The holding furnace 230 transfers a predetermined amount of the molten copper 110 to the lower trough 260 while maintaining the molten copper 110 at the predetermined temperature. The adding unit 240 continuously adds a predetermined metal element to the molten copper 110 in the lower trough 260. Examples of the metal element added to the molten copper 110 include tin (Sn), indium (In), titanium (Ti), magnesium (Mg), silver (Ag), aluminum (Al), calcium (Ca), and manganese (Mn). That is, preferably, at least one of these metal elements is added to the molten copper 110.

[0021] The downspout 260 is provided downstream of the holding furnace 230 and transports the molten copper 110 transferred from the holding furnace 230 to the downstream tundish 300. The downspout 260 is connected to the adding unit 240. Note that the adding unit 240 is not limited to being connected to the downspout 260, and may be connected to the holding furnace 230 or the tundish 300, for example.

[0022] The tundish 300 is provided downstream of the lower trough 260, temporarily stores the molten copper 110 transferred from the lower trough 260, and continuously supplies a predetermined amount of molten copper 110 to the continuous casting machine 500. In this manner, the molten copper 110 to be supplied to the continuous casting machine 500 is prepared.

[0023] A pouring nozzle 320 for pouring out the stored molten copper 110 is connected to the downstream side of the tundish 300. The molten copper 110 stored in the tundish 300 is supplied to a continuous casting machine 500 through the pouring nozzle 320.

[0024] The continuous casting machine 500 is a device for performing so-called belt-wheel type continuous casting, and includes, for example, a casting ring 1 and a belt (casting belt) 3. As shown in FIG. 2, the casting ring 1 has a cylindrical main body 1a, with a groove 2 formed on the outer periphery of the main body 1a. The casting ring 1 rotates around a rotation axis 6 during the copper material casting process, and the rotation axis 6 is aligned along a horizontal plane. A cylindrical holder 5 that holds the main body 1a is disposed inside the main body 1a. That is, the casting ring 1 is fixed to the holder 5 and rotates together with the holder 5. The casting ring 1 may be a cylindrical or disk-shaped member.

[0025] The belt 3 is configured to rotate and be able to come into close contact with a portion of the outer peripheral surface of the casting ring 1. Molten copper (molten metal) 110 flowing out from a tundish 300 shown in Fig. 1 is poured into a space 4 formed by the groove 2 of the casting ring 1 and the belt 3. In other words, the tundish 300 and the pouring nozzle 320 form a supply unit 330 that supplies the molten copper 110 into the groove 2 of the casting ring 1.

[0026] The casting ring 1 and belt 3 are cooled, for example, by cooling water. As a result, the molten copper 110 is cooled and solidified (coagulated), and rod-shaped cast bars 120 are continuously cast. In other words, the continuous casting machine 500 equipped with the casting ring 1 is a casting unit that solidifies the molten copper 110 and casts the cast bars 120. After casting the cast bars 120, the continuous casting machine 500 separates the belt 3 from the rotating casting ring 1 and sends the cast bars 120 out of the continuous casting machine 500.

[0027] The hot rolling mill 620 is provided downstream of the continuous casting machine 500 (on the cast bar discharge side) and is a rolling section that continuously rolls the cast bar 120 delivered from the continuous casting machine 500 to form a rolled material. That is, the hot rolling mill 620 is used to pull the cast bar 120 out of the groove 2 of the casting ring 1 and transport it outside the continuous casting machine 500. The rolled material formed by rolling the cast bar 120 using the hot rolling mill 620 is subjected to a surface cleaning process between the hot rolling mill 620 and the winder 640, whereby the copper wire (copper wire rod) 130 is cast.

[0028] The winder (coiler) 640 is provided downstream (on the copper alloy material discharge side) of the hot rolling device 620, and winds up the copper wire 130 that is transferred from the hot rolling device 620 through the surface cleaning treatment device. Through the above steps, the copper wire (copper wire rod) 130 can be formed.

[0029] Here, the cast bar 120, which is removed from the casting ring 1 shown in FIG. 1 and before being rolled in the hot rolling mill 620, contains oxygen. Similarly, the copper wire 130 also contains oxygen. The oxygen content (oxygen concentration) in the copper of each of the cast bar 120 and the copper wire 130 is 450 mass ppm or less. From the viewpoint of increasing the hardness of the copper wire 130 to be produced, a more preferable value for the oxygen content is 120 mass ppm or less.

[0030] Next, the specific structure of the outer periphery of the main body 1a of the casting ring 1 will be described with reference to Figure 2. Figure 2 is a cross-sectional view taken along the rotation axis (hereinafter simply referred to as the rotation axis) 6 of the casting ring 1, and shows the main body 1a of the casting ring 1, the belt 3 covering the outer periphery of the main body 1a, and the holding part 5. Figure 2 is a cross-sectional view taken along line AA in Figure 1. Neither the molten copper nor the cast bar is shown in Figure 2.

[0031] A groove (recess) 2 recessed toward the rotary shaft 6 is formed annularly along the outer periphery of the main body 1a on the outer side surface in the radial direction (hereinafter simply referred to as the radial direction) P1 of the cast ring 1, i.e., the outer peripheral surface. The groove 2 extends along the outer periphery (circumferential direction) of the cast ring 1 and is formed annularly so as to surround the rotary shaft 6. The width of the groove 2 in the direction along the rotary shaft 6 (also referred to as the rotary shaft direction Q1) gradually decreases from the outer periphery of the cast ring 1 toward the rotary shaft 6. In other words, the cross-sectional shape of the groove 2 is an inverted trapezoid whose width gradually decreases toward the rotary shaft 6. The inverted trapezoidal cross-sectional shape of the groove 2 makes it easier to remove the cast bar 120 (see FIG. 1 ) solidified in the groove 2 from the groove 2. In other words, it makes it easier to separate the cast bar 120 solidified in the groove 2 from the cast ring 1.

[0032] Although not shown here, the surface of the groove 2 is continuously covered with a refractory film made of soot, also called soot. The surface of the belt 3 facing the bottom of the casting ring 1 is also covered with a refractory film made of soot. The soot is a mold release agent that makes it easier to separate the casting bar 120 from the casting ring 1 and the belt 3.

[0033] The casting ring 1 is made primarily of copper (Cu), for example. The casting ring 1 may also be made of copper mixed with chromium (Cr) or zirconium (Zr). Molten copper 110 poured into the space (in the groove 2) between the belt 3 and the outer circumferential surface of the casting ring 1 absorbs heat from the casting ring 1, which is mainly made of copper, which has a relatively high thermal conductivity, and is cooled by this, solidifying before making one revolution around the casting ring 1.

[0034] 1, the diameter D1 of the casting ring 1 is the maximum width in the radial direction P1 of the casting ring 1 shown in FIG. 2, and the diameter D1 is, for example, about 3 m. The casting ring 1 rotates together with the molten copper 110 and the casting bar 120.

[0035] <Detailed structure of the casting part> The detailed structure of the cast part shown in FIG. 3 will be described.

[0036] The belt-type continuous casting apparatus 13 of this embodiment has a continuous casting machine 500 as a casting section that continuously casts cast bars 120 by pouring molten copper 110 into a space 4 (see FIG. 2 ) formed by bringing the belt 3 into close contact with the rotating casting ring 1. The belt-type continuous casting apparatus 13 further has a cleaning section 9 that cleans the belt 3 after it has been separated from the casting ring 1, a heating section 8 that heats the belt 3 after it has been separated from the casting ring 1, and a temperature measuring section 11 that measures the temperature of the belt 3 after it has been separated from the casting ring 1.

[0037] The belt 3 is, for example, about 30 m long, and moves around the periphery of the casting ring 1. The movement of the belt 3 is guided by pulleys 7 provided at multiple locations.

[0038] The cleaning section 9 is a place where the belt 3 is cleaned after the cast bar 120 cast in the continuous casting machine 500 is separated from the belt 3 and moves back toward the continuous casting machine 500. In the cleaning section 9, for example, water is sprayed at high pressure onto the belt 3. This is jet cleaning using water. This jet cleaning cleans the belt 3 and also lowers the temperature of the belt 3.

[0039] The heating section 8 is disposed downstream of the cleaning section 9 in the traveling direction S1 of the belt 3, and is a section for heating the belt 3. In the heating section 8, the belt 3 is heated by a heater that uses gas or the like. That is, by heating the belt 3, moisture that has adhered to the belt 3 by jet cleaning in the cleaning section 9 is blown off, the belt 3 is dried, and the temperature of the belt 3 is increased. Since it is not preferable to bring the belt 3 with moisture adhered thereto into contact with the molten copper 110, the belt 3 is heated in the heating section 8 to blow off and remove the moisture that has adhered to the belt 3.

[0040] The temperature measuring unit 11 is disposed downstream of the heating unit 8 in the traveling direction S1 of the belt 3, and is a location for measuring the temperature of the belt 3. Specifically, the surface temperature of the belt 3 heated by the heating unit 8 is continuously measured by a contact or non-contact temperature sensor.

[0041] At this time, the temperature of the belt 3 measured by the temperature measuring unit 11 is immediately fed back to the control unit 12.

[0042] The release agent applicator 10 is located downstream of the temperature measuring unit 11 in the traveling direction S1 of the belt 3 and immediately before the belt 3 is supplied to the casting ring 1, and applies a release agent (soot) to the belt 3. The soot is a refractory film made of soot, and is applied to the belt 3 by, for example, incomplete combustion of acetylene.

[0043] The control unit 12 constantly manages the surface temperature of the belt 3 measured by the temperature measurement unit 11. That is, the control unit 12 continuously monitors the surface temperature of the belt 3 fed back from the temperature measurement unit 11, and adjusts the temperature of the belt 3 during casting to a preset value.

[0044] That is, the control unit 12 continuously monitors the measurement results of the surface temperature of the belt 3 by the temperature measurement unit 11, and based on the temperature measurement results, adjusts the degree of cleaning and heating of the belt 3. In this way, the control unit 12 automatically adjusts the temperature of the belt 3 during casting so that it becomes a preset value.

[0045] <Belt-type continuous casting method> The belt type continuous casting method of this embodiment will be described.

[0046] The belt-type continuous casting method of this embodiment is a casting method in which molten copper 110 is poured into a space 4 formed by a casting ring 1 rotating around a rotation axis 6 and a circulating belt 3, thereby continuously casting cast bars 120.

[0047] As shown in Figure 3, in a continuous casting machine 500, which is the casting section, molten copper 110 is poured into a space 4 (see Figure 2) formed by tightly contacting a rotating casting ring 1 with a belt 3. This allows for the continuous casting of cast bars 120. The casting ring 1 rotates together with the molten copper 110 and cast bars 120.

[0048] The molten copper 110 poured into the space 4 between the belt 3 and the outer peripheral surface of the casting ring 1 loses heat to the casting ring 1, which mainly contains copper, which has a relatively high thermal conductivity, and is thereby cooled. The molten copper 110 then solidifies before making one full revolution around the casting ring 1 due to the heat it loses and is cooled by the casting ring 1.

[0049] Next, the belt 3 is separated from the rotating casting ring 1, and the cast bar 120 is sent out of the continuous casting machine 500. At this time, because a mold release agent (soot) has been applied to the belt 3 and the grooves 2 of the casting ring 1, the casting ring 1 and the cast bar 120, and the belt 3 and the cast bar 120, can be easily separated from each other.

[0050] Next, the belt 3, which has been separated from the casting ring 1, moves around the casting ring 1, and then moves toward the casting ring 1 again, is washed in the washing section 9 (washing step).

[0051] In the cleaning unit 9, for example, jet cleaning is performed. Specifically, water is sprayed onto the belt 3 at high pressure to clean the belt 3 and also to lower the temperature of the belt 3.

[0052] Next, in the traveling direction S1 of the belt 3, the belt 3 is heated by the heating unit 8 provided downstream of the cleaning unit 9 (heating step). In the heating unit 8, the belt 3 is heated by a heater using, for example, gas. By heating the belt 3, the moisture adhering to the belt 3 is removed in the cleaning unit 9, and the temperature of the belt 3 is further increased. In other words, the belt 3 is heated in the heating unit 8, and the moisture adhering to the belt 3 is removed by being removed.

[0053] Next, in the traveling direction S1 of the belt 3, the temperature of the belt 3 is measured by the temperature measuring unit 11 provided downstream of the heating unit 8 (temperature measuring step). Specifically, the surface temperature of the belt 3 heated in the heating unit 8 is continuously measured by a contact or non-contact temperature sensor.

[0054] The temperature of the belt 3 measured by the temperature measuring unit 11 is immediately fed back to the control unit 12.

[0055] Next, a release agent (soot) is applied to the belt 3 by a release agent application unit 10 provided downstream of the temperature measurement unit 11 in the traveling direction S1 of the belt 3 and immediately before the belt 3 is supplied to the casting ring 1 (release agent application step). The soot is a refractory film made of, for example, soot.

[0056] In the traveling direction S1 of the belt 3, the temperature of the belt 3 is measured before the release agent is applied in the release agent application section 10, and after measuring the temperature of the belt 3, the release agent is applied to the belt 3 immediately before the belt 3 is supplied to the casting ring 1.

[0057] In addition, in the traveling direction S1 of the belt 3, the heating of the belt 3 in the heating step (heating section 8) is carried out before the release agent is applied, and the temperature of the belt 3 is measured between the heating step (heating section 8) and the release agent application step (release agent application section 10).

[0058] The belt type continuous casting apparatus 13 of this embodiment is equipped with a control unit 12 that adjusts the cleaning and heating of the belt 3 based on the measurement results of the temperature of the belt 3 by the temperature measurement unit 11. That is, the belt type continuous casting apparatus 13 automatically adjusts the degree of cleaning and heating of the belt 3 based on the measurement results of the temperature of the belt 3. In other words, the control unit 12 automatically adjusts the magnitude of the cleaning amount and the magnitude of the heating amount of the belt 3 based on the measurement results of the temperature of the belt 3 by the temperature measurement unit 11.

[0059] In this way, the belt-type continuous casting device 13 has a control unit 12 that automatically adjusts the amount of cleaning and heating of the belt 3 based on the results of temperature measurement of the belt 3 by the temperature measurement unit 11, thereby allowing the control unit 12 to manage the temperature of the belt 3.

[0060] The temperature measurement unit 11 is located downstream of the heating unit 8 and the cleaning unit 9 in the traveling direction S1 of the belt 3, i.e., closer to the insertion port into the casting ring 1 (where the pouring nozzle 320 is located) than the heating unit 8 and the cleaning unit 9.

[0061] This makes it possible to measure the temperature of the belt 3 immediately before it is supplied to the casting ring 1, and also to control the temperature of the belt 3 immediately before it is supplied to the casting ring 1 by the control unit 12.

[0062] The release agent application section 10 is preferably provided in the traveling direction S1 of the belt 3 just before the belt 3 is supplied to the casting ring 1. In this case, the heating section 8 is provided upstream of the release agent application section 10 in the traveling direction S1 of the belt 3, and the temperature measurement section 11 is provided between the heating section 8 and the release agent application section 10.

[0063] This makes it possible to measure the temperature of the belt 3 heated by the heating unit 8 before the release agent is applied to the belt 3.

[0064] The control unit 12 of the belt-type continuous casting apparatus 13 constantly manages the surface temperature of the belt 3 measured by the temperature measurement unit 11. That is, the control unit 12 continuously monitors the surface temperature of the belt 3 fed back from the temperature measurement unit 11 and automatically adjusts the temperature of the belt 3 during casting so that it reaches a preset value. For example, when the measured temperature of the belt 3 is higher than the preset value, the control unit 12 adjusts the amount of cleaning and heating of the belt 3 by increasing the water pressure for cleaning in the cleaning unit 9 to lower the temperature of the belt 3. On the other hand, when the measured temperature of the belt 3 is lower than the preset value, the control unit 12 adjusts the amount of gas supplied to the burner in the heating unit 8 to increase the temperature of the belt 3.

[0065] This allows the control unit 12 to control the temperature of the belt 3 just before it is supplied to the casting ring 1.

[0066] <Effects of this embodiment> In the belt-type continuous casting apparatus 13, the control unit 12 continuously monitors the temperature measurement results of the belt 3 and adjusts the degree of cleaning and heating of the belt 3 based on the measurement results, thereby automatically adjusting the temperature of the belt 3 to a preset value. This makes it possible to control the temperature of the belt 3 just before it is supplied to the casting ring 1, thereby improving the quality of the cast material. As a result, the quality of the cast bar 120 (cast material) in the process following the casting process (rolling process) can be improved.

[0067] Furthermore, the control unit 12 automatically adjusts the degree (level) of heating of the belt 3 in the heating step (heating unit 8) and cleaning of the belt 3 in the cleaning step (cleaning unit 9), thereby controlling the temperature of the belt 3 to be higher or lower. This also makes it possible to adjust the temperature of the casting material to be higher, thereby sealing any casting defects (blowholes) in the cast bar 120. As a result, casting defects in the cast bar 120 can be reduced, improving the quality of the next process. This also increases the yield in the subsequent winding process. Furthermore, the non-defective product rate and first-run rate in the casting process can be improved.

[0068] Furthermore, since it is possible to maintain an appropriate belt temperature, the release agent is applied to the belt 3 in a good condition, and the heat insulating effect of the belt 3 can be improved. This allows the temperature of the casting material to be raised, and casting defects (blowholes) in the cast bar 120 can be sealed. As a result, the quality of the next process can be improved.

[0069] The invention made by the present inventors has been specifically described above based on the embodiments, but it goes without saying that the present invention is not limited to the above-described embodiments and can be modified in various ways without departing from the spirit of the invention.

[0070] For example, in the above embodiment, the belt-type continuous casting apparatus has been described as having a hot rolling mill and a winder, but the belt-type continuous casting apparatus does not have to have a hot rolling mill or a winder, as long as it has at least a continuous casting machine (casting unit) having a casting ring and a casting belt.
