[0002] Electroslag casting is a secondary refining technology, which is a comprehensive metallurgical casting process that combines secondary refining of molten steel and directional solidification. Its principle is that an electric current passes through the slag resistance heat of the liquid slag pool to melt the metal electrode. The melted metal converges into molten droplets, and when dripping, it passes through the slag layer and enters the metal molten pool, and then crystallizes and solidifies into an ingot in a water-cooled mold. A wide slab electroslag ingot is a semi-finished large-section steel product produced by the electroslag remelting technology, and is mainly used for subsequent rolling of wide-width plates, such as ship plates, pressure vessel plates, etc.

[0028] Example 3: Please refer to Figure 2 , Figures 6-8 The present embodiment further illustrates the first embodiment. The tray 29 is used to support the wide slab electroslag ingot located at the grinding station. The tray 29 is installed on the outside of the conveying mechanism. The number of trays 29 on the outside of the conveying mechanism is two groups, and they are symmetrically distributed. The limiting component is used to limit the two sides of the wide slab electroslag ingot. The limiting component is installed on the tray 29. The limiting component includes a limiting block 30 that can move at the upper end of the tray 29. Both ends of the limiting block 30 are provided with a bevel portion 31, and the wide slab electroslag ingot passes through the bevel portion 31. 31 is in sliding contact with the limit block 30, and the limit block 30 is against both sides of the wide slab electroslag ingot to limit the wide slab electroslag ingot to prevent the electroslag ingot from displacement during the grinding process of the wide slab electroslag ingot. Two symmetrically distributed limit sliders 32 are fixedly installed on the lower end of the limit block 30, and the limit sliders 32 are slidably connected to the tray 29 through the limit straight groove. The limit slider 32 is used to prevent the limit block 30 from detaching from the tray 29, and two symmetrically distributed cylindrical pins 33 are fixedly embedded on the side of the limit block 30 away from the chain 4.

[0029] A positioning block two (34) is movably sleeved on the outer side of one end of the cylindrical pin rod (33) far away from the limit block (30), and the positioning block two (34) is fixedly connected with the tray (29). A third spring (35) is movably sleeved on the outer side of the cylindrical pin rod (33), and the two ends of the third spring (35) are respectively in movable abutment with the limit block (30) and the positioning block two (34). The third spring (35) can drive the positioning block two (34) to move through the positioning block two (34). The cylindrical pin rod (33) is used to prevent the third spring (35) from bending. A positioning component is installed on the limit block (30), and the positioning component includes a positioning rod (36) penetrating through the limit block (30).

[0030] An eccentric dial (37) is rotatably installed at the upper end of the positioning rod (36), and the connection mode between the eccentric dial (37) and the limit block (30) is movable abutment. The eccentric dial (37) can drive the positioning rod (36) to move up and down during rotation. A washer (38) is fixedly sleeved on the outer side of the positioning rod (36). A fourth spring (39) is movably sleeved on the outer side of the positioning rod (36), and the two ends of the fourth spring (39) are respectively in movable abutment with the limit block (30) and the washer (38). The fourth spring (39) can drive the positioning rod (36) to move downward through the limit block (30) and the washer (38). A plurality of pin holes (40) are arranged on the tray (29) at equal intervals, and the positioning rod (36) is inserted and pulled out of the tray (29) through the pin holes (40). When the positioning rod (36) is inserted into the pin holes (40), the limit block (30) can be positioned.

[0031] Working principle: When grinding and cleaning the surface of a wide slab electroslag ingot, the operator first places the electroslag ingot slab between the two limit blocks (30), and makes the electroslag ingot slab located between two adjacent stoppers (6) on the chain (4). The moving support (2) drives the grinding disc (3) to move to clean the surface of the electroslag ingot slab. After the front surface of the electroslag ingot slab is cleaned, the sprocket (5) rotates to make the chain (4) convey the electroslag ingot slab between the first support rod (10) and the second support rod (11). Then, the motor (8) drives the disc (9) and the electroslag ingot slab to rotate through the rotating shaft (7). After the electroslag ingot slab is turned over to another conveying mechanism, the chain (4) in the other conveying mechanism conveys the electroslag ingot slab between the two limit blocks (30), and the moving support (2) drives the grinding disc (3) to move again to grind and clean the reverse side of the electroslag ingot slab. Through the cooperation of the conveying mechanism and the turning mechanism, the electroslag ingot slab can be automatically turned over during the process of cleaning the surface of the electroslag ingot slab, so as to effectively reduce the workload of the operator and improve the cleaning efficiency of the surface of the electroslag ingot slab.

[0032] During the process of the chain 4 transporting the electroslag ingot slab between the first support rod 10 and the second support rod 11, the electroslag ingot slab will move upward through the inclined side three drive strip 13. The strip 13 will extrude the electroslag ingot slab under the driving force of the compression elastic force of the first spring 17. Cooperating with the first support rod 10, it can clamp electroslag ingot slabs with different thicknesses, which is beneficial for the flipping mechanism to flip electroslag ingot slabs with different thicknesses. During the process of clamping and rotating the electroslag ingot slab by the first support rod 10 and the strip 13, the ball 23 will rollingly contact the arc drive strip 26 through the inclined side one 27. During this process, the long ejector rod 21 drives the mounting frame 18 and the friction plate 19 to move until the friction plate 19 abuts against a plurality of tooth grooves 20 on the outer side of the rectangular pin rod 14. By the friction plate 19 abutting against the plurality of tooth grooves 20, the rectangular pin rod 14 and the strip 13 are locked, so as to effectively ensure the stability during the flipping process of the electroslag ingot slab and prevent the electroslag ingot slab from displacing or falling off.

[0033] When placing the electroslag ingot slab, the operator places the electroslag ingot slab between the two limit blocks 30, and then pushes the electroslag ingot slab. During the movement of the electroslag ingot slab, it will drive the two limit blocks 30 to move away from each other through the inclined side two 31. After the electroslag ingot slab is clamped between two adjacent stoppers 6 on the chain 4, the operator rotates the inclined side one 27, so that the positioning rod 36 is inserted into the corresponding pin hole 40 under the driving force of the compression elastic force of the fourth spring 39 to position the limit block 30. The cooperation of the two limit blocks 30 and the four stoppers 6 positions the electroslag ingot slab, which can prevent the electroslag ingot slab from displacing during the grinding process. Similarly, when cleaning the reverse side of the electroslag ingot slab, the chain 4 drives the electroslag ingot slab to move so that the electroslag ingot slab is inserted between the two limit blocks 30. The operator only needs to rotate the eccentric dial 37 to insert the positioning rod 36 into the pin hole 40 to position the limit block 30.
