镁铬耐火砖用耐火浇注料铬铁矿粉2500#超细铬矿粉由天然铬矿经选矿，水洗，烘干，筛分，研磨等工艺生产而来。由于铬矿具有较低的热膨胀系数，与镁砂按照一定工艺混合后，可以改善耐火砖的体积膨胀，还可以避免单一铬质耐火砖的荷重软化温度低的缺陷。
Chromite powder 2500# ultra-fine chromite powder for refractory castables for magnesia-chrome refractory bricks is produced from natural chromium ore through processes such as beneficiation, washing, drying, screening, and grinding. Since chromium ore has a low thermal expansion coefficient, it can improve the volume expansion of refractory bricks after being mixed with magnesia according to a certain process, and can also avoid the defect of low load softening temperature of single chromium refractory bricks.
