Chromite Sand AFS40-45 and Chromite Powder 200# Powder for Magnesium Chromium Castables
Magnesium-based castables have good slag resistance and corrosion resistance to molten steel. It is usually used in key parts such as slag lines of high-grade steel ladles. However, magnesium sand itself has a thermal expansion coefficient of up to, poor thermal shock resistance, and low anti-stripping ability. Chromite sand AFS40-45 and chromite powder 200 # fine powders are usually added as auxiliary materials in magnesium chromium castables to improve the thermal shock resistance and service life of magnesium-based refractory materials.
