Problems solved by technology

This stacking method causes the two outermost billets of each billet to bend due to uneven cooling; and if the billet bends too much, it will affect the normal production of the rolling process, such as failing to enter the furnace or rolling , roller idling, etc.

Abstract

The invention belongs to the field of steelmaking continuous casting, and relates to a method for preventing square billets from laterally bending in a stack cooling process, which comprises the following steps: when casting billets are primarily cooled by a rolling cooling bed, advance to the tail end of the cooling bed, are collected by a collecting device to be in a six-piece closed state, and are ready to be offline by a travelling crane, fixing clips are clamped at two ends of the casting billets; casting blank offline stacking is carried out through a traveling crane (clamp), the clamp is recycled when the surface temperature of the casting blank is reduced to 300 DEG C or below, sidewise bending caused by internal stress in the cooling process is reduced, and convenience is created for production of the next procedure.

Description

technical field [0001] The invention belongs to the field of steelmaking and continuous casting, and relates to a method for preventing side bending of a billet in the process of stack cooling. Background technique [0002] During the continuous casting process of the billet casting machine, when the billet needs to be cooled off-line, the general billet still has a surface temperature of 600-700°C after being cooled by the tumbling cooling bed. The factory will use the fixture to go offline. Using the fixture to go offline will inevitably cause a gap between every 6 billets (the number of a clamp) and the other 6 billets (for the fixture to exit). This stacking method leads to the bending of the outermost two billets of each square billet due to uneven cooling; and if the billet is too bent, it will affect the normal production of the rolling process, such as not being able to enter the furnace or rolling. , roller idling, etc. SUMMARY OF THE INVENTION [0003] In view ...
