Optimization design of mold for high speed slab caster
The production of high-speed continuous casting is the achievement and realization ways of the high effi-ciency,green and intelligent development of continuous casting.Aiming at realizing high-speed continuous casting,the mold is studied on the process control and equipment design,and the mold model is established.Based on the heat transfer analysis of mold,it is proposed that the key to optimize high-speed mold is to improve the homogeneity of Cu plate with the premise of increasing the cooling efficiency.By the multi-objective optimization,a new method to optimize the water seam of mold is proposed.After optimization,the hot surface temperature and the temperature difference of Cu plate of the mold are reduced significantly,which can obviously reduce the risk of breakout caused by the uneven cooling of the slab at high speed casting.This is of great significance for the promotion and applica-tion of high speed production technology of caster.
