LD Slag is produced during the separation of molten Steel Slag from impurities in steel-making furnaces.
Slag being a complex solution of silicates and oxides is lighter and hence, floats on top of the molten mass of steel. It is then tapped into a Slag pot which solidifies on cooling and is then separated.
The free metallic Slag is magnetically separated and the non-metallic Slag left after this is segregated in different sizes based on its usage.
Deliberate control of the steel manufacturing process influences both the quality of the Steel and the Slag. At Tata Steel IBMD, comprehensive range of chemical examinations are carried out to ensure the quality of LD Slag is supreme.
A hardstand is a paved area for parking heavy vehicles, storing raw materials/ finished products etc.
Due to better strength, abrasion and impact resistance than natural aggregates, Steel Slag aggregates are particularly suitable for use in areas subjected to heavy vehicle loads and high shear stress.
Portland Slag Cement (PSC) Manufacturing:
LD Slag can also be used as a partial replacement of Blast Furnace Slag in PSC making. In fact, LD Slag reduces the cost of making PSC. Also, inclusion of LD Slag in PSC making in the BIS Specifications strengthens its widespread usage.
