Parameter

‘Jun’ brand sintered magnesia-alumina spinel is made from industrial alumina and calcined magnesia as raw materials, and is sintered in an ultra-high temperature shaft kiln through a multi-stage homogenization process. It has a high bulk density, well-developed crystals, small grain size, high content of spinel phase, good sintering activity, and uniform structure. Magnesia-alumina spinel has superior characteristics such as corrosion resistance, anti-peeling, good slag resistance, good thermal shock stability, and high temperature resistance.

Magnesia-alumina spinel sinterata de alta qualitate provvidet garantia pro productione de materialia refractaria non-formata et formata de alto rendimento. Est materia prima idealis pro producta refractaria, ut bricks de magnesia-alumina spinel pro fornaces rotatorias cementarias, bricks pro linings de ladles, et castabilia pro ladles. Utitur late in metallurgia ferrea, fornaces rotatorias cementarias, et fornaces pro industria vitrea. Secundum contentum de alumina, magnesia-alumina spinel sinterata dividitur in SAM-50, SAM-66, SAM-78, et SAM-90.
