Progress of breakout prediction technique for slab casters at Baosteel

Breakout prediction is one of the important techniques of continuous casting. The software and hardware of the breakout prediction system have been upgraded and revamped time after time since slab casters were put into operation at Baosteel, and its performance and technical indexes have been improved remarkably. This paper reviews the development of the breakout prediction technique of the No.1 Steelmaking Plant at Baosteel. The newly developed BBPS(II) is introduced, and the mould mapping system of the No.4 slab caster is described. The breakout prediction technique is playing an important role in increasing production capability, improving slab quality and decreasing breakout events.
