Low turbidity chrome sand for foundry works well for thick-wall castings. The casting wrinkle and heavy leather defects of large thick-walled castings have always been a problem that plagued foundry enterprises. Even the use of chromite sand with superior performance is prone to defects that are difficult to clean. However, through a series of material and technical control methods, the quality of large thick-walled castings can be effectively improved.

Chromite sand (chromite ore sand) is often used as molding sand for large thick wall steel castings. It has the characteristics of high sintering temperature and strong resistance to liquid steel penetration. It is applicable to Iron chromium oxide sand, which can avoid most of the mechanical and chemical sand sticking. Thus it can make castings obtain smooth and clean surface quality. Chromite sand is very popular in heavy steel foundry fields.

Chromium-based minerals are commonly used products in the industry. From the source, there are natural chromite sand and synthetic chromite sand.

The chromite sand price was raised at the beginning of 2023. On February 9, 2022, South Africa declared a state of disaster nationwide due to worsening power shortages. At present, Eskom has to cut off a large number of customers’ electricity every day due to insufficient power supply.

Chromite sand is a kind of chilling material, and 46% Cr2O3 Chromite sand is the main material for producing chrome-based ladle filler sand (Drainage sand). Chromite sand for ladle filler is one of the main applications of natural chromite sand.

Chromite sand for casting comes from natural chrome ore. The manufacturer should produce chrome ore blocks to chromite sand or powder with specific AFS fineness. In the meantime, our QC team must conduct quality control throughout the production process. We adopt strict quality control standards to ensure the good quality and particle distribution of chromite ore for casting.
