Chromium Ore Powder 325mesh# For Lost Foam Coating
Chromium ore powder can be used in lost foam coatings. Chromite flour is often used in casting coatings.
The reasons are as follows:
Excellent thermal conductivity: chromite powder has stronger thermal conductivity, can accelerate cooling and heat conduction, and improve casting efficiency.
Good chemical stability: It has good resistance to alkaline slag when in contact with molten metal, does not react chemically with iron oxide, etc., can prevent the penetration of molten metal, and avoids the occurrence of sticky sand defects. Therefore, Chromite flour is an ideal choice in lost foam coatings, which can improve the performance of the coating and the casting effect.
Precise fineness: chromite powder has a pass rate of more than 90-100%, uniform particles, and can be better dispersed in the coating to improve the uniformity and stability of the coating.
Low moisture content: Dry without caking, ensuring that the coating will not be affected by humidity problems during use.
High refractory temperature: The melting point of chromite powder is 2180 degrees, and the sintering temperature is greater than 1850 degrees. It can remain stable at high temperatures to prevent the coating from failing at high temperatures.
Our chromium ore powder another name chromite powder, is made from high-quality L6 layer chrome ore imported from South Africa. It is a natural ore. After washing, drying, crushing, screening, grinding and other processes, different types of chromite sand and chromite powder are produced.
Application: Used in high duty grey iron and steel foundries as core and mould making sand, in steel production it is used as a fller, used for production of green glass beverage containers.
