The bottom of the first placement groove 3 is connected with the second placement groove 4. The length and width of the first placement groove 3 are both greater than the length and width of the second placement groove 4. The first placement groove 3 and the second placement groove 4 can be plugged in and matched with the cloth flow ladle water inlet 5. The cloth flow ladle water inlet 5 comprises a first plug block 6 and a second plug block 7. The first plug block 6 can be plugged in and matched with the first placement groove 3, and the first plug block 6 cannot pass through the second placement groove 4. The second plug block 6 can be plugged in and matched with the second placement groove 4. In the present invention, the first plug block 6 and the second plug block 7 can be plugged into and matched with the first placement groove 3 and the second placement groove 4, and the first plug block 6 cannot pass through the second placement groove 4, thereby ensuring that the height position of the cloth flow bag water inlet 5 can be installed more accurately, solving the problem that the traditional inverted trapezoidal cloth flow bag seat brick and the cloth flow bag water inlet cannot be accurately installed at the installation height; at the same time, the stepped setting at the edge of the cloth flow bag water inlet 5 and the first placement groove 3 and the second placement groove 4 can reduce the risk of steel leakage at the joint, thereby ensuring safe production.

[0020] Specifically, a first ridge 8 is provided at the bottom of the adjacent side of the first and second flow ladle seat bricks 1, 2, as described in this embodiment, and a second ridge 9 is provided at the corresponding position of the second flow ladle seat brick 2 and the first ridge 8. In the present invention, the first ridge 8 and the second ridge 9 are deliberately coordinated to ensure that the first and second flow ladle seat bricks 1, 2 are at the same height and the stepped arrangement at the edges can reduce the risk of steel leakage at the joints and ensure safe production.
