Resumo
Centre segregation and porosity, in high quality blooms and billets, such as rail and bearing grades, can give rise to inconsistent mechanical properties and potential failure of the final product. Although static soft reduction can be used to improve the internal quality, this is only applicable for one set of casting parameters. Operational flexibility and improved quality, together, can only be achieved with a dynamic soft reduction system that takes into consideration transient casting speed, solidification process and material behaviour. This paper will discuss the successful implementation of Siemens VAI dynamic soft reduction, DynaGap, on bloom and billet casters and the benefits achieved.
