从China供应商批发进口200# 325# 400# Powder Chromit — FOB条款

This foundry-grade chromite powder is a fine-ground chromite ore (FeCr2O4) with a minimum Cr2O3 content of 46%, offered in 200#, 325#, and 400# mesh sizes. The material is primarily sourced from large-scale mining operations in South Africa and Kazakhstan, which are known for producing chromite with consistent chemical composition. Its high thermal conductivity provides effective chilling properties during metal solidification, while its low thermal expansion helps maintain dimensional stability in moulds and cores.

In foundry applications, the powder is used for core and mould making in high-duty grey iron and steel casting. Its refractoriness and near-neutral basicity allow compatibility with a broad range of resin bonding systems and inorganic binders. For the steel industry, it serves as a well filler to protect sliding gates in large holding ladles. When ground to a fine flour, it is also used in the production of green glass beverage containers.

Buyers in the foundry and steel sectors typically source this material for its consistent grading and thermal performance. Packaging is usually in 1-metric-tonne big bags or 25kg sacks, with international trade terms commonly quoted as CIF or FOB.
