Magnesium aluminum spinel refractory brick for rotary kiln fire bricks lining

Short Description:

kiln fire bricks Introduction

Magnesia alumina spinel bricks is a kind of alkali refractory bricks, the cement kiln block can also be synthetized as spinel, which is made into an amorphous refractory used for integral structures and internal lining. The production process of magnesite refractory bricks is basically in phase with the production process of common magnesia brick, However, each level of granule in the batching component is composed of a sintered synthetic spinel or an electrically fused spinel, or a mixture of the two.
