High Alumina Brick & High Aluminum Castable Difference 1.Difference between high alumina bricks and high alumina castables is that one is a high alumina refractory brick made by high temperature sintering, and the other is a bulk material made of high alumina aggregate, powder and binder. 2.Appearance shape, high alumina brick is sintered refractory brick with fixed shape and size, high aluminum castable is bulk material, no fixed shape. 3.Construction method, refractory bricks are constructed by masonry, and refractory castables are casted. 4. The price of high aluminum bricks is higher than the high aluminum refractory castables. High Alumina Bricks Definition High alumina brick refers to alumina with a content of more than 48% and less than 90%. It is made of refractory brick made of high alumina bauxite or sillimanite. high alumina refractory brick is usually divided into three according to the Al2O3 content in the product: The Al2O3 content of th...

Refractory Materials fo Hot Metal Pretreatment Effect 1.Strong scouring and wear of high temperature molten iron and slag. Since the temperature of molten iron is as high as 1400 ℃or higher,  industrial refractory material for furnace lining  and the stirring and blowing equipment will be strongly washed by the high temperature iron during the pre-existing process of molten iron, industrial refractory material is required to be used in the hot metal pretreatment process. The refractory material has high temperature strength and is resistant to wear. 2.Chemical attack of various pretreatment agents. Since various desulfurizing agents react with the kiln lining and the refractory materials for the stirring and blowing devices during use, and can generate some low-melting substances, dissolved in molten iron, especially for some low-melting soda and other fluxes, They make the refractory erosion of various pretreatment agents particularly severe, so the refracto...
