Description of Magnesia-iron Spinel Brick:
Magnesia-iron spinel brick is an excellent refractory product with "chromium-free" in the firing zone of cement kilns. With excellent kiln coating hanging ability, good thermal shock resistance, cement clinker erosion resistance and low thermal expansion rate, it has excellent performance in the firing zone of cement kilns.
