Corundum Mullite Bricks Description
Corundum Mullite Bricks belong to high alumina refractory bricks that are manufactured with main phase of corundum and mullite. Corundum Mullite Bricks as a kind of refractory bricks are produced with high purity raw materials. Because the oxide impurity with low melting point will reduce the corundum mullite bricks’ high temperature property. Compared of the refractory bricks price, Corundum Mullite Bricks’ price is higher than the common high alumina bricks’.
Corundum Mullite Bricks Properties
Corundum Mullite Bricks have various excellent service properties in furnace or kiln, such as high temperature strength, high temperature creep resistance, thermal shock resistance and erosion resistance.
Talk about the typical physical and chemical properties, that corundum mullite bricks contain more than 85% Al2O3 and 0.45% Fe2O3, show the apparent porosity as 19% , more than 55MPa cold crushing strength and more than 1700℃ refractoriness under load.
Corundum Mullite Bricks Manufacturing Process
Corundum mullite bricks generally are manufactured with synthesized mullite. Adopt mullite granule as the aggregate and α- Al2O3 powder as the powder material. And also can use fused or sintered corundum granule as the aggregate and synthesized mullite powder as the powder material. Burdening of the aggregate and powder materials according to the certain ratio and grain size distribution mix with binding agent of sulfite pulp waste liquid in order. After complete mixing, use friction brick press or hydraulic brick press to mold into shapes. And then firing the green bricks under the temperature of 1650~1750℃ after drying.
Points for Attention: those corundum mullite bricks adopt the second manufacturing process method of using the fused or sintered corundum granule as the aggregate that will have the bad density. Thus the second method is not used for wide.
