Product Description

 

Chrome ore

Chromite sand is a special sand for foundry. It is a natural spinel mainly composed of chromite. After crushing, grinding, and screening, it is divided into specified particle sizes, which is suitable for molding (core making) sand. Chromium ore can be divided into primary Cr2O3 (>45%) and secondary Cr2O3 (>35%) according to chemical composition.

 

feature:

 

1. Heating volume stability

2. High thermal conductivity

3. Strong alkali resistance

4. Solid phase sintering, non-sticky sand

 

Advantages of chromite sand

Compared with silica sand, chromite sand can avoid most of the sand sticking to the casting, so it can also save the cost of surface treatment. Additionally, chromite can be recycled multiple times for use in different technologies.

Among all the chromite ore in the world, the chromite ore produced in South Africa is of the best quality. Therefore, Haixu Abrasives imports raw chromite ore from there and refines it to a higher purity, reaching 46% Cr2O3.

How does a foundry choose a grain size?
Generally speaking, the smaller the casting that needs to be made, the finer the grain size that the foundry will use. The image below is shown for reference:

 

Less than 500KGS

 

500-1000KGS

1-10 tons

10-30 tons

30-100 tons

40-70

45-50

45-50

40-45 years old

35-40
