Cao-Sio2 Mould Powder Refractory Material for Steelmaking Continuous Steel Casting Process

Cao-Sio2 Mould Powder Refractory Material for Steelmaking Continuous Steel Casting Process. CaO-SiO2 Mould powder Refractory Material for steelmaking during the continuous steel casting process is a functional molten slag material specially used for continuous casting moulds. It spreads evenly on the molten steel surface and melts to form a liquid slag layer, ensuring the quality of cast strand formation. The mould powder features excellent spreadability and superior thermal insulation, preventing crust formation on the molten steel surface. It isolates air to avoid reoxidation of molten steel. With good lubricating performance, it lubricates the solidified shell and mould wall, reducing friction and preventing sticking and breakout. It can adsorb inclusions in molten steel to purify steel quality. Meanwhile, it delivers stable and uniform heat transfer to guarantee good surface quality of cast strands, and performs well on various continuous casters for different section sizes.
