Product Introduction
Ordinary Magnesia-Chrome Brick is a basic refractory product manufactured from high-quality sintered magnesia and chromite ore as the principal raw materials. It is produced through high-pressure pressing and high-temperature firing. The product features high refractoriness, excellent resistance to alkaline slag corrosion, and good performance under severe high-temperature operating conditions. It is widely used in the transition zone of cement rotary kilns, small and medium-sized non-ferrous metallurgical furnaces, permanent linings of steel ladles, and other applications requiring resistance to alkaline slags and high temperatures.
