Description

Technical Field

[0001] The invention relates to the technical field of blast furnace water-cooled walls, and in particular to a copper-steel bimetallic blast furnace water-cooled copper wall formed by metallurgical compounding. Background Art

[0002] The blast furnace cooling stave is an important water-cooled part of the blast furnace lining. It is installed in the blast furnace body, furnace waist, furnace belly, furnace hearth and other parts. It not only withstands high temperature, but also withstands the wear of furnace charge, erosion of slag and scouring of gas flow. It must have good comprehensive properties such as thermal strength, thermal shock resistance, and resistance to rapid cooling and heating. The cooling stave can effectively prevent the furnace shell from being heated and red-hot. After the blast furnace lining bricks are burned, the slag skin mainly protects the cooling stave itself and maintains the safe production of the blast furnace. Therefore, the material and performance of the cooling stave determine its working life and even the life of the blast furnace body.

DETAILED DESCRIPTION

[0035] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] Example 1

[0037] A copper-steel bimetallic blast furnace water-cooled copper wall made by metallurgical compounding, such as Figure 1 , Figure 2 and Figure 3As shown, it includes a cooling stave 1, a water channel 2, a water inlet pipe 3 and a water outlet pipe 4. The cooling stave 1 is composed of a hot surface 11 and a cold surface 12. The hot surface 11 is made of copper, and the cold surface 12 is made of steel. A water channel 2 for circulating cooling liquid is provided in the cooling stave 1. The cold surface 12 is provided with a water inlet pipe 3 and a water outlet pipe 4 connected with the water channel 2. The water inlet pipe 3 and the water outlet pipe 4 are welded on the cold surface. The hot surface 11 made of copper and the cold surface 12 made of steel are metallurgically composited, and their bonding surfaces are completely composited. The water channel 2 is formed on the hot surface 11 by deep drawing and drilling. There are four groups of water channels 2. An annular groove surrounding the water channel 2 is provided on the bonding surface of the hot surface 11 and the cold surface 12. A sealing ring 5 is fixedly installed in the groove by a clamping method. The sealing ring 5 is made of elastic high-temperature resistant rubber material.

[0038] The blast furnace water-cooled wall structure includes a hot surface 11 and a cold surface 12. The hot surface 11 made of copper slabs and the cold surface 12 made of steel slabs are metallurgically composited to achieve 100% bonding of the bonding surface, with high bonding strength. The bonding surface will not separate during the use of the blast furnace. At the same time, a cooling liquid flow channel is formed by cooperating with a water channel 2 through a water inlet pipe 3 and a water outlet pipe 4, and heat exchange is accelerated by continuous circulation. In addition, an additional sealing ring 5 can seal water in the cooling wall 1 when the water channel 2 may be deformed due to high-temperature thermal cycles, resulting in water leakage on the bonding surface.

[0039] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a locking assembly 6 for strengthening the connection is also included, the locking assembly 6 includes a fixing bolt 61, a protrusion 62, a locking bolt 64 and a rack 66, the four corners of the cold surface 12 are installed with cylindrical fixing bolts 61, the fixing bolts 61 pass through the cold surface 12 and vertically extend into the hot surface 11, the fixing bolts 61 can slide and rotate relative to the cooling wall 1, the bottom of the fixing bolt 61 is provided with a radially protruding protrusion 62 made by an integrated molding process, the corners of the upper and lower ends of the protrusion 62 are wedge-shaped to facilitate alignment with the in-and-out grooves, the cooling wall 1 is provided with a matching card slot, and the top center of the fixing bolt 61 A hexagonal hole 63 is provided, and a locking bolt 64 is installed on the side of the cold surface 12 by threaded cooperation. The locking bolt 64 is pressed inward when it is rotated clockwise. When the locking bolt 64 is tightened, pressure is applied to the fixing bolt 61 to limit its rotation. The side surface of the fixing bolt 61 is provided with square tooth grooves 65 arranged at equal intervals. A rack 66 meshing with the tooth grooves 65 is connected between the two fixing bolts 61. The rack 66 consists of a long rod in the middle and a toothed meshing portion on the side surfaces at both ends. The rack 66 can move horizontally relative to the cooling wall 1, and the fixing bolt 61 can rotate synchronously under the transmission action of the tooth grooves 65 and the rack 66.

[0040] When the water-cooled copper wall is in use, the fixing bolts 61 are inserted into the slots at the four corners of the cooling wall 1, and then one of the fixing bolts 61 is rotated with a hexagonal wrench or other tools. When the fixing bolt 61 rotates, the tooth grooves 65 on its side surface push the rack 66 to move, so that the other three fixing bolts 61 rotate synchronously, and then the fixing bolts 61 at the four corners can be rotated at the same time, and the protrusions 62 at the bottom are staggered and clamped with the sliding grooves, and then the locking bolts 64 are tightened so that the head is pressed against the fixing bolt 61, fixing it at the current angle, and further strengthening the connection between the hot surface 11 and the cold surface 12 of the cooling wall 1.

[0041] Example 2

[0042] On the basis of Example 1, Figure 8 As shown, it also includes a mounting assembly 7 for auxiliary installation, and the mounting assembly 7 includes a mounting plate 71 and fixing bolts 73. The outer side of the cooling wall 1 is provided with a mounting plate 71 that is tightly fitted by bolts. The mounting plate 71 is frame-shaped and surrounds the hot surface 11 and the cold surface 12. Slots 72 are symmetrically provided on both sides of the mounting plate 71. Slidable fixing bolts 73 are provided in the slots 72, and two fixing bolts 73 are provided on one side.

[0043] When the blast furnace wall needs to be partially replaced, it can be fixedly connected through the mounting plate 71 on the outside of the cooling wall 1, and the fixing bolts 73 can slide along the slots 72 on both sides of its short sides to facilitate adjustment of its position and avoid additional drilling.

[0044] like Fig. 9 As shown, it also includes a docking assembly 8 for facilitating the docking of an external pipe with the water inlet pipe 3 or the water outlet pipe 4. The docking assembly 8 includes a sleeve 81 and a ball 82. The outer sides of the water inlet pipe 3 and the water outlet pipe 4 are both sleeved with matching sleeves 81. Four balls 82 are evenly spaced around the inner wall of the sleeve 81. The balls 82 are symmetrical around the axis. The outer walls of the water inlet pipe 3 and the water outlet pipe 4 are provided with grooves matching the balls 82.

[0045] like Fig.10 and Fig.11As shown, the docking assembly 8 also includes a cylinder body 83, a piston rod 84, a ring block 85, an air bag 86 and an air pipe 87. A small cylindrical cylinder body 83 is welded at the bottom of the water inlet pipe 3 and filled with gas. A piston rod 84 is slidably connected in the cylinder body 83. The piston rod 84 consists of a piston that fits and seals with the inner wall of the cylinder body 83 and a support rod at the top of the piston. A slidable ring block 85 is provided on the outer side of the bottom of the water inlet pipe 3. When the sleeve 81 moves downward, the ring block 85 can be pushed down synchronously. The ring block 85 and the top of the piston rod 84 are fixedly connected by strong glue. When the ring block 85 moves downward, it pushes the piston rod 84 to slide downward. An elastic annular air bag 86 is connected between the water inlet pipe 3 and the sleeve 81. An air pipe 87 is connected between the air bag 86 and the cylinder body 83 to form a channel, and the gas in the cylinder body 83 can flow into the air bag 86.

[0046] like Fig.12 , Fig.13 and Fig.14 As shown, it also includes an adding component 9 for adding cleaning agents or other auxiliary agents, and the adding component 9 includes a branch pipe 91, a movable block 92, a fixing ring 93, an elastic member 94, a rotating shaft 95 and a blade 96. The sleeve 81 is vertically connected to and communicated with a branch pipe 91 extending horizontally outward. A reduction structure is provided near the end of the internal channel of the branch pipe 91. The inner diameter of the part of the pipeline close to the end of the sleeve 81 is larger. A truncated cone-shaped movable block 92 is movably connected at the reduced diameter. The maximum diameter of the movable block 92 is consistent with the inner diameter of the branch pipe 91 at the reduced diameter part. The fixing ring 93 is fixedly installed in the branch pipe 91 by welding. An elastic member 94 is connected between the fixing ring 93 and the movable block 92. The elastic member 94 adopts a stainless steel compression spring. The movable block 92 blocks the inlet of the branch pipe 91 under the action of the elastic member 94. A rotatable shaft 95 is provided at the center of the fixing ring 93. Blades 96 that rotate with the water flow are clamped on the shaft 95 along the circumferential direction. The blades 96 are symmetrically arranged and the inclination directions on both sides are opposite. The water flowing in different directions can drive the blades 96 on one side to rotate respectively.

[0047] When connecting the water pipe connected to the water source to the water inlet pipe 3, the sleeve 81 is first sleeved on the outside of the water inlet pipe 3. The ball 82 on the inner wall of the sleeve 81 can make it slide down smoothly along the water inlet pipe 3. After the sleeve 81 slides down to the bottom and contacts the ring block 85, the ring block 85 is squeezed and pushed downward, so that it drives the piston rod 84 to move downward along the cylinder body 83, and the gas in the cylinder body 83 is transported to the air bag 86 along the air pipe 87, so that the air bag 86 expands to further fix the sleeve 81 and the water inlet pipe 3, and the gap between the sleeve 81 and the water inlet pipe 3 caused by the ball 82 is blocked to prevent water from flowing through the gap. Then, the water source can be turned on to send water into the waterway 2 to assist in cooling. In addition, the cleaning agent can be removed from the branch pipe 91, and the movable block 92 is pressed inward to move along the branch pipe 91 to the connection with the sleeve 81. The elastic member 94 is compressed, and the movable block 92 retreats to the pipe part with a larger inner diameter of the branch pipe 91, and no longer blocks the inlet. After the cleaning agent is sent in, the movable block 92 moves back to the reduced diameter under the reset action of the elastic member 94, and blocks the reduced diameter part of the pipe, and the inlet is closed. After the water flow is introduced, the water will push the blades 96 to rotate when flowing in the branch pipe 91, so that it drives the rotating shaft 95 to rotate, and then the blades 96 on both sides rotate at the same time, and the mixed liquid of the cleaning agent and water is stirred and mixed, and then sent into the waterway 2 along the sleeve 81 and the water inlet pipe 3 to clean the waterway 2 in the cooling wall 1.
