Product Description

 

Product Description

Fused magnesia-alumina spinel

Fused magnesia-alumina spinel is a new type of high-

purity synthetic refractory raw material, which is made of

alumina and high-purity light-burned magnesia as the

main raw materials in an electric arc furnace after being

melted at a high temperature above 2000 ºC and then

cooled. There are mainly MA-65, MA-70 and other

models, and various types of fused magnesia-aluminum

spinel can also be produced according to customer

requirements.

Application

 

Fused magnesia-aluminum spinel has the characteristics of high bulk density, good thermal ballast stability and strong corrosion resistance, which can effectively improve the slag resistance, thermal shock resistance, thermal ballast resistance of refractory products, prefabricated parts, and unshaped refractory materials. Stability and high-temperature mechanical properties are suitable for the production of high-grade magnesia-alumina bricks, high-performance magnesia-aluminum castables, large-scale cement kilns, magnesia-aluminum ladle castables, blast furnace tap ditch castables, sliding nozzles, ladle lining bricks, continuous casting slides , ideal raw materials for nozzle bricks and open hearth furnace roof bricks, etc.
