Casting Powder is a crucial part for the casting which acts as a lubricant to flow the hot metal to solidification.
Casting powders significantly determine the stability of the continuous casting process of steel at all casting speeds.
- To protect liquid steel against oxidation.
- To provide lubrication for the solidifying steel.
- To control, optimize, and insulate the heat transfer from the liquid steel to the mould and the ambient in horizontal and vertical directions.
- To absorb the inclusions from the liquid steel to produce cleaner cast steel product.
- To provide chemical protection to the liquid steel from oxidation and other undesired reactions.
The high basicity of the mould powder increases its capability to assimilate non-metallic inclusions.
