Resumo
Continuous casting of steel is basically a process in which liquid metal starts its solidification at the meniscus of the so called mould. Here at the very first process step the heat extraction is a multiple of any other heat exchanging process and the mould material suffers from temperatures which is at the limit for copper. Because of the large range of steel grades cast with carbon contents of 0.03 % - 1.00 %, the steel shrinkage factor varies substantially. Therefore the mould shape, taper and other design features need to be carefully chosen and may be calculated with finite element method (FEM). Mould-Systems can incorporate electromagnetic stirring and the like in order to distribute the hot liquid steel over a longer length. Mould level control and powder detection systems are also available. This paper describes cartridge mould systems, state of art CONVEX moulds, integrated moulds, ALL- CONVEX moulds and looks into the future designs. Productivity figures and mould optimizing- and refurbishing processes are mentioned.
