Parameter
"Jun" brand sintered alumina-magnesia spinel is based on industrial alumina and dead burnt magnesite, through the multi-stage homogenization process，sintered in ultra-high temperature shaft kiln, with large volume density, high spinel phase content, good crystal development, uniform structure, stable performance. Also alumina-magnesia spinel has corrosion resistance, peeling resistance, good slag resistance, good thermal shock stability, high temperature resistance and other characteristics.
High quality sintered alumina-magnesia spinel provide guarantee for the production ofshaped and unshaped high -performance refractory materials. lt is an ideal raw material for fire-resistant products such as magnesia-alumina spinel brick for cement rotary kiln, ladle brick, and refractory carstables for ladles. On steel metallurgical, cement rotary kiln and glass industrial kiln.According to alumina content, sintered magnesia-alumina spinel is classified into SAM-50SAM-66,SAM-78 and SAM-90 varieties.
