Chrome ore USES For drainage sand materials, casting, ceramic, glass and refractory, etc.
Chromite sand applicable types: 1) casting grade is special    2)special metallurgy level.
(1)Chrome ore in casting production is mainly used for large steel surface sand, prevent casting surface adhering sand;
(2)Secondly the grinding powder for the refractory aggregate of foundry coating, chrome ore is chilling material, when modelling (core) alternative part cold iron.
Chromite sand for casting coating, refractory materials, brake pads, high-performance ceramic materials, ceramic and glass colorant, friction material, chemical and metallurgical casting, etc.
