The swivel rotates and drives the cylinder 12 to rotate. Since the cylinder 12 is threadedly connected to the push rod 13, and under the limit of the moving rod 15, the connecting plate and the fixed block 14, the rotation of the cylinder 12 causes the push rod 13 to move. The movement of the push rod 13 will also cause the connecting plate, the moving rod 15 and the fixed block 14 to move. The movement of the push rod 13 will push the old nozzle body 6 to move. At the same time, the movement of the moving rod 15 will also cause the fixed block 14 to move, and at the same time, the insert rod 16 will be removed from the slot. Then move the old nozzle body 6. When the nozzle body 6 moves, the block 10 will also move into the chute 8 and squeeze the spring 11. Then the old nozzle body 6 can be disassembled, and then the new nozzle body 6 can be installed. You only need to push the new nozzle body 6 and the fixed plate 7 into the movable groove 5 and the fixed groove 4, and slide to the other side of the block 10. When it slides, the block 10 will also move toward the inside of the chute 8 and squeeze the spring 11. Then reverse the swivel, and rotate the swivel to rotate the cylinder 12 and move the push rod 13, the connecting plate, the moving rod 15 and the fixed block 14, and insert the insert rod 16 into the slot, thereby fixing the nozzle body 6. After that, the molten steel will flow from the vertical pipe 2 to the inside of the tundish and be introduced into the crystallizer through the nozzle body 6.
