Problems solved by technology

[0002] At present, the continuous casting process adopts welding cold material for the placement structure of the medium and large continuous casting slab section, and welds the steel plate in the middle of the cold material frame as the main component of the cold material, which is very important for the crystallizer. If the cross-section of the billet and the round billet are large, if they are placed in this way, the center temperature of the continuous casting billet will be too high during the pouring process, resulting in leakage accidents, and at the same time, the continuous casting billet will be dragged, Leakage, resulting in large economic losses and production accidents

Abstract

The invention discloses a continuous casting blank section casting cold material placing structure and a placing method thereof. The placing structure comprises a crystallizer, a dummy bar head arranged in the crystallizer, and the following parts arranged in sequence in the vertical direction from bottom to top: asbestos cloth, multiple steel wire shots and casting bricks; multiple asbestos ropes are filled in a gap between the crystallizer and the dummy bar head; the asbestos cloth respectively covers the upper surface of the dummy bar head and the multiple asbestos ropes; the casting bricks are coated with cold material frames; multiple reinforcements are arranged on the top surfaces of the cold material frames; and the multiple steel wire shots cover the asbestos cloth. The placing structure can reduce the economic loss in the casting process, and can prevent production accidents caused by overhigh center temperature of continuous casting blanks.

Description

technical field [0001] The invention relates to a continuous casting production technology, in particular to a placement structure and a placement method for continuous casting slab cross-section pouring cold material. Background technique [0002] At present, the continuous casting process adopts welding cold material for the placement structure of the medium and large continuous casting slab section, and welds the steel plate in the middle of the cold material frame as the main component of the cold material, which is very important for the crystallizer. If the cross-section of the billet and the round billet are large, if they are placed in this way, the center temperature of the continuous casting billet will be too high during the pouring process, resulting in leakage accidents, and at the same time, the continuous casting billet will be dragged, Leakage, resulting in greater economic losses and production accidents. [0003] Therefore, it is an urgent problem to be so...
