摘要
高拉速连铸生产是连铸高效、绿色、智能化发展的成果和实现途径.以实现高拉速连铸为目标,从工艺控制和装备设计角度对结晶器开展研究,建立结晶器传热模型,在对结晶器传热分析的基础上,提出了高拉速结晶器优化设计的核心是在提高冷却效率前提下,提高铜板冷却均匀性的优化思路.采用多目标策略优化的方法,提出了一种结晶器水缝优化设计的新方案.优化后的结晶器铜板热面温度和温差显著降低,从而可显著降低高拉速下由坯壳冷却不均造成的漏钢风险.这对于连铸机高拉速生产技术的推广和应用具有重要意义.
Abstract
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.
