Mould Flux Film between Mould and Steel Shell - Effect on Heat Flux and Defect Formation

摘要

This work desrcibes the occurence of the so called slag detect in industrial continuous casting of stainless steel slabs. When liquid casting powder infiltrates into the gap between mould and shell, a part of it solidifies on the mould surface. This layer of the powder slag can grow in thickness and can change in its structure during hours of casting, leading to a reduction in heat flux and an increase in frequency of the defect type.
