Abstract

Abstract

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.
