Chrome sand AFS(35-40)
Description
Chrome ore sand, also known as chromite sand, is a special type of foundry sand. It is a natural spinel mainly made of chromite. It is crushed, ground, and sieved to the specified fineness, and is suitable for modeling (core making) sand. Chrome ore is divided into 2 grades according to chemical composition; first grade Cr2O3≥45%; second grade Cr2O3≥35%. Chrome ore is mainly used in the casting production for the surface sand of large steel castings to prevent the surface of the castings from sticking to the sand; secondly, it is ground to be used as the refractory aggregate of the casting coating; chrome ore is the chilling material and is used in the modeling (core making) Sometimes it can replace part of cold iron.
Effect
Casting chromite sand is a product processed by natural chromite ore through crushing, screening and other processes. Its main chemical composition is cr2o3. This kind of sand has stable heating volume and high thermal conductivity. When it comes in contact with molten metal, it not only has It has good resistance to alkaline slag, does not react with iron oxide, etc., and has the characteristics of solid phase sintering, which can prevent the penetration of molten metal and avoid sand defects. It is suitable for all kinds of stainless steel and alloy steel. And carbon steel gradually molds the raw sand and paint for core making.

Use
It is suitable for making drainage sand raw materials, casting, ceramics, glass and refractory materials.
Applicable types of chromite sand: special for foundry grade and special for metallurgical grade. Chrome ore is mainly used in casting production for the surface sand of large steel castings to prevent the surface of castings from sticking to sand; secondly, it is ground for refractory aggregates for casting coatings. Chrome ore is the chilling material, which is used in modeling (making sand cores). ) Can replace part of cold iron. Chromite sand is suitable for casting coatings, refractory materials, automobile brake pads, high-performance ceramic materials, ceramic and glass colorants, friction materials, chemical and metallurgical casting and other fields.
