Chromite Powder 325#mesh For Lost Foam Coating
Chromite Powder 325#mesh can be used in lost foam coatings. Chromite powder is often used in casting coatings.
The reasons are as follows:
Precise fineness: Chromite Powder 325mesh 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 sand 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.
Excellent thermal conductivity: Chromite sand 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 Powder 325#mesh is an ideal choice in lost foam coatings, which can improve the performance of the coating and the casting effect.
Chromite Powder 325#mesh is an iron chromium oxide found naturally in the earth crust. It is the most industrially important mineral for the production of metallic chromium by far, used in the production of stainless and tool steel. It is also used as a refractory material because of its high heat stability. Chromite fines extracted from chromite sand is used in Chrome plating & alloying for production of corrosion resistant super alloys. Chromite fines is also used as a pigment for glass, glazes & paints and as an oxidizing agent for tanning leather. 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.
