Abstract The reasons for the breakout of the heavy-gauge slab continuous caster are found by analyzing the information of breakout accidents in the heavy-gauge slab continuous casting process at a domestic steelmaking plant. The production practice shows that the main factors leading to breakout include uneven heat transfer in the mould, ill-performance of slag, mould level fluctuation, and improper operation etc. And the control and improved measures are put forward to prevent the breakout effectively, which has achieved good results.
