Then the impurities fall into the inside of the leakage trough, and then into the inside of the bearing frame. At the same time, the impurities fall into the inside of the second through groove and into the inside of the dust collection frame. After the process is completed, the gate opens, causing the fixed frame to rise back to the designated position. Then the steel body is pushed again, allowing it to enter the inside of the pusher-type heating furnace for heating. This operation is repeated for subsequent steel bodies.

[0046] Then the steel body enters the interior of the fixed frame 41. The fixed frame 41 drives the assembly plate 13 to move. The assembly plate 13 drives the third brush 46 to move, and at the same time drives the scraper 47 to move. The third brush 46 cleans the side of the steel body, and the scraper 47 scrapes the impurities on the side of the steel body, causing the impurities to fall off. At the same time, the wiping block 44 wipes the side of the steel body as it falls.

[0047] When the fixed frame 41 moves to the bottom, the hydraulic cylinder 8 drives the moving frame 9 to move. The moving frame 9 drives the second brush 45 to move. The second brush 45 cleans the top of the steel body, causing the impurities at the top to fall to the top of the receiving plate 48. Then the impurities fall into the inside of the leakage trough 17 and then into the inside of the bearing frame. At the same time, the impurities fall into the inside of the second through groove and enter the inside of the dust collection frame 10. After the operation is completed, the gate 2 is opened, causing the fixed frame 41 to rise back to the designated position. Then the steel body is pushed to enter the inside of the push-type heating furnace 1 for heating. Then the subsequent steel bodies repeat this operation.

At the same time, the wiping block (44) wipes the side of the steel body during the falling process. Step 3: When the fixed frame (41) moves to the bottom, the hydraulic cylinder (8) drives the moving frame (9) to move. The moving frame (9) drives the second brush (45) to move. The second brush (45) cleans the top of the steel body, so that the impurities at the top fall to the top of the receiving plate (48). Then the impurities fall into the inside of the leakage trough (17) and then into the inside of the bearing frame. At the same time, the impurities fall into the inside of the second channel and enter the inside of the dust collection frame (10). After the end, the gate (2) is opened, so that the fixed frame (41) rises back to the designated position. Then the steel body is pushed to enter the inside of the push-type heating furnace (1) for heating. Then the subsequent steel bodies repeat this operation.
