Mullite Semi-Streight Refractory Brick for Steel Industry Thin Sheet FireBrick
The Description:
Half a brickHalf piece firebrick (two pieces, three pieces,2 pieces,3 pieces), referred to as half piece. According to the material is divided into high aluminum half sheet, clay half sheet, corundum half sheet and so on. The specifications and dimensions of firebricks are: 230*114*32mm, 230*114*20mm, the selection of high-quality calcined high bauxite clinker, clay clinker and binder first through granulation, powder process, after a certain proportion of mixing, by large tonnage press molding, high temperature fired products, products with high mechanical pressure strength, appearance of accurate size, high temperature resistance, high fire resistance, good slag resistance, wear resistance, long service life And other characteristics. Characteristics and uses: It is a weakly acidic refractory product with good thermal shock stability and long service cycle. It is suitable for boiling furnace, hot blast furnace, cupola, heating furnace, reduction furnace, smoke chamber, flue, etc.
