Chrome sand Chrome powder -200 mesh -400 mesh -325 mesh

Chromite sand for foundry is a natural processing product of chromite after crushing, screening and grading. The main chemical composition of chromite is cr2o3. After heating, the sand has a stable volume and high thermal conductivity. When in contact with molten metal, it not only It has good alkali slag resistance, does not chemically react with iron oxide, etc., and has the characteristics of solid phase sintering, which can prevent the infiltration of molten metal and avoid sand defects. It is suitable for various stainless steel, alloy steel, carbon The steel gradually forms the original core and coating.

1. Technical service:
A technical team with more than 20 years of casting experience can provide better technical services.

2. Guaranteed delivery time:
Global logistics network, China loading port warehouse, guaranteed delivery time.

3. Chromium ore raw material:
Chromium ore raw material comes from the best chrome ore - no more "left over".

4. Customizable size:
AFS (about 25-70), the particle size distribution of sand can be customized according to customer requirements.

5. Cleanliness:
The turbidity is less than 100ppm (the sand is very clean), and it does not contain low melting point substances. We frequently upgrade and replace sand cleaning equipment to ensure the cleanliness of chromite sand.

 Chrome sand in the foundry industry

Its properties enable the material to be used as core and molding sand in high-strength gray iron and steel foundries. Its high thermal conductivity gives it good cooling properties and its low thermal expansion gives it good dimensional stability. Its alkalinity is close to neutral, and can be widely used in resin bonding systems and inorganic binders, with high refractoriness and wide sieving distribution.

Chrome sand in the steel industry

In steel production, chromite sand is used as filler to protect the sliding doors of large ladles.

Chrome sand in the glass industry

When ground into a fine powder, chromite sand can be used to produce green glass beverage containers.

The first step: the chrome ore raw material is washed with water.

Step2. Dry the raw materials to remove moisture;

Step3. The dried raw materials enter the vibrating screen to screen out the particle size required by the customer;

Step4, the size of the magnetic screen to achieve the purpose of removing iron and silicon. After magnetic separation, the chromium content reaches more than 46%, and the silicon content is less than 1%.

Step5: Packaging the finished product.
