Service — a case study
One steel plant was looking to increase the performance of their casting operation (more output, higher product quality, and more operational flexibility).
Vesuvius recommended the Shroud Exchange Mechanism, SEM85 with VPC (Vesuvius Precision Control). This solution combines a system to exchange the tundish shroud without cast interruption and without raising the tundish, automatic mould level control with +/- 1.5 mm accuracy, and automatic clogging prevention (stopper oscillation) with mould level set point modulation (to increase tube life).
As a result, annual caster production rose from 790,000 tonnes to 870,000 tonnes. Quality improved thanks to better accuracy in mould level control (95% of the time working in automatic), and as a result, there was a 56% reduction in diverted slabs on thin plate steel grades. Safety was also improved with the new ability to stop steel flow with a "blank" plate and better working conditions for operators.
