Product Introduction
Product Details
Sintered alumina magnesia spinel
"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 of shaped and unshaped high-performance refractory materials.It 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-50,SAM-66,SAM-78 and SAM-90 varieties.
