Brief introduction of chromite sand

Chromite sand mainly made of quartz sand, petroleum coke, smelted by above 2500 in the electric furnace, the hardness is between corundum and diamond, the hardness is superior to corundum, it has the function of conductivity and thermal conductivity.

Characteristices of chromite sand

1. High temperature strength

2. Good thermal conductivity

3. Impact resistance

4. High strength

5. Corrosion and erosion resistance

6. Good thermal shock resistance

Application of chromite sand

It is suitable to process metals and non-metallic materials. Such as gray cast iron,non-ferrous

metals, stone,leather,rubber and so on . It also widely used in refractories,metallurgical.
