    Blast furnace cement refers to the cement made of blast furnace slag. Slag, also known as granulated blast furnace slag, is a glassy material formed when the slag melted by blast furnace ironmaking is quenched without crystallization. Its main components are calcium oxide, silicon oxide and alumina. It has high potential activity. Under the action of activator, it can be combined with hydration to form hydraulic cementitious material.

    After more than 30 years of efforts, continuous cast steel has gradually replaced ingot mold casting. Continuous casting slabs with thickness of 150 ~ 250mm are widely used in various countries to produce plates. In the 1980s, continuous casting technology has made a breakthrough. At present, the continuous casting technology that can pour thinner slabs and higher pouring speed to make the production capacity have economic scale is developed
