Functions of casting mould powder:
1. Molten steel Insulation
2. Isolate air, prevent the secondary oxidation of molten steel
3. Purify steel slag interface, absorb inclusions in molten steel
4. Lubricate billet shell and improve solidification heat transfer.
Advantages of CH series Casting Mould Powder
•Casting Mould Powder forms a good lubricating film on the surface of mould not allowing solidifying metal adhesion to the mould.
•Casting Mould Powder provides easy and fast solidification of metal by providing high rate heat removal from metal.
•Casting Mould Powder gives very good performance at elevated temperatures with the aid of its well selected additives.
•Casting Mould Powder increases the quality of metal surface.
•Casting Mould Powder can help to purify molten steel
•Casting Mould Powder is cheaper than Rapeseed/Casting Oil.
