[0006] The left and right outer walls of the tundish body are both equipped with ear plates, the side walls of the ear plates are provided with fixing holes, and the fixing holes are equipped with lifting rods;

[0007] The end of the hoisting rod is equipped with a limit ring a, the outside of the hoisting rod is located inside the limit ring a and is equipped with a limit ring b, and a hanging cavity is provided between the limit ring a and the limit ring b;

[0008] The hoisting rod extends through the fixing hole to the interior of the tundish body and is screwed with a fastening nut. A fastening groove is provided at the end of the hoisting rod, and the fastening rod is inserted into the interior of the fastening groove.

[0009] Furthermore, a fastening cylinder is sleeved on the outside of the fastening rod, and three anti-slip rods are assembled on the outer wall of the fastening cylinder. The three anti-slip rods are distributed in a triangle, and the outer wall of each anti-slip rod is provided with anti-slip teeth.

[0010] Furthermore, an annular groove is provided on the outer wall of the fastening nut, the end of the anti-slip rod is arranged in the annular groove, the outer wall of the anti-slip rod is provided with an external thread, and the inner wall of the fastening cylinder is provided with an internal thread.

[0011] Furthermore, a rotating disk is provided at the end of the anti-slip rod.

[0012] Furthermore, a sealing gasket is provided on the outside of the lifting rod at the front end of the fastening nut.

[0013] Furthermore, the structure of the overflow trough is an open rectangular overflow trough, the bottom surface of the overflow trough is inclined downward by 10°-15°, the width of the overflow trough is 1.25m-1.3m, and the depth of the overflow trough is 0.8m.

[0014] The beneficial effects of this patent are:

[0015] A continuous casting tundish that is convenient for taking out materials has a simple structure and is easy to operate. By arranging ear plates on the outer wall of the tundish body and arranging lifting rods on the ear plates, and by arranging limit rings a and b on the lifting rods, a lifting cavity is formed between the two, thereby facilitating external lifting and further facilitating lifting and taking out materials.
