Current Status of Slag Design in Metallurgical Processes

Since the use of metallurgical slags is of great importance due to its versatile functions at high temperatures, comprehensive information is required to optimize the processes in iron and steelmaking processes. Primary silica-based slag composition can drastically deviate from expected norms by the significant amounts of additional constituents during processes. Accordingly, the comprehensive change in the slag composition and viscosity has a dramatic impact on the physico-chemical properties of the slags. In the current lecture, special focus will be put on the future technology relating the optimization of metallurgical slag composition and viscosity to cope with the situation with low quality of materials introduced into the metallurgical processes.
