Abstract

Today, secondary metallurgical units represent the versatile usable connection between melting and casting plants in steelworks. Future-oriented process-improving measures must be consequently developed and applied to ensure that the secondary metallurgical facilities achieve their full extent of availability and thus a high level of productivity at low operative costs. Furthermore, metallurgical processes must be optimised to ensure that steel grades to be produced fulfil the continually increasing demands with regard to steel purity, precision of chemical composition and low contents of undesired tramp elements. RH and RH TOP vacuum units use the principle of the vacuum recirculation process, and are in particular applied in flat-product steelplants to enable mass production of deep drawing grades with very low contents of Carbon under economically favourable conditions. In addition, RH and RH TOP vacuum units are used for the removal of hydrogen, for deoxidation and for the precise adjustment of the chemical analysis and temperature of the molten steel.
