摘　　要：基于TRIZ理论,建立了连铸钢包开浇系统的功能模型,通过因果链原因分析法,确定了产生问题的关键原因;充分应用技术冲突、物理冲突、物质-场模型以及效应等工具对连铸钢包开浇工艺进行了改进,产生了8种创新解。针对某厂80 t钢包具体情况,通过方案对比优选出最佳方案,即采用真空复合滑板控流结构。实施后取得了良好的效果,钢包自动开浇率达到97%以上,虽然与采用传统的引流砂开浇工艺的自开率基本持平,但是降低了钢中大颗粒夹杂物产生量,有效解决了传统引流砂开浇工艺带来的引流砂污染钢液的顽疾。Based on TRIZ theory,the function model of ladle pouring system had been established,and the key causes of the problem had been determined by causal chain analysis.By fully applying the tools of technical conflict,physical conflict,material-field model and effect,the start-up process of continuous casting ladle was improved,eight kinds of innovative solutions were produced,and the optimal scheme was determined by scheme comparison.The scheme adopts vacuum composite flow control skateboard and achieves good process effect.The automatic casting rate of the ladle can reach more than 97%.Although it is basically the same as the self-opening rate of the traditional drainage sand casting process,the new scheme can reduce the amount of large particle inclusions in the steel and effectively solve the drainage sand pollution caused by the traditional drainage sand casting process.
