The products have been renowned as the fourth generation castables, which can be applied in all applications where low cement, ultra-low cement and no cement castables are applied. Corundum based SFC is suitable for the ladle bottom, around the seating block, gap fitting of EAF roof. Both mullite-based SFC and alumina-based ones can be applied for the permanent lining of ladle and tundish. SFC can also be installed by machine.
