Strict control of casting defects is crucial for the production of pump and valve steel castings. So what are the performance characteristics of South African chrome iron ore sand? Below, the chromium iron ore sand manufacturer will give you a detailed introduction!
Advantages and disadvantages of South African chromite sand:
1. Example Analysis of Casting Defects
Pump and valve steel castings have complex structures, uneven wall thickness, and irregular distribution of hot nodes. To prevent defects such as shrinkage, porosity, and cracks from occurring and obtain castings with dense microstructure, high requirements are put forward for the casting process.

2. Chromite and chromium ore sand
In the metallurgical industry, chromite is mainly used for the production of ferrochrome and metallic chromium. Chromium iron is used as an additive in steel to produce various special steels with high strength, corrosion resistance, wear resistance, high temperature resistance, and oxidation resistance, such as stainless steel, acid resistant steel, heat resistant steel, ball bearing steel, spring steel, tool steel, etc.
