Application
* Chromite sand is mainly used for surface sand of large cast steel parts in casting production to prevent the surface sand of castings.
* Secondly,it is used for refractory aggregate of casting coating. Chrome ore is a cold material, in the molding (core) can replace part of the cold iron.
Packing & Delivery
Our refractory materials are available in 25kg paper sacks, 1000kg bulk bags or as bulk as standard.
Tianjin,Shanghai,Qingdao port or any port in china.
