The Al2O3 content of the Yellow Low Bulk Density 1350C Fire Clay Bricks Insulating Refractory Brick refractory bricks used For steel Furnace is from 30-48%.During the manufacturing,first mix the clay chamotte with refractory clay powder,then prepared with clay aggregate into dry mud,high pressure molding,sintering at about 1400C.Under high temperature,the Yellow Low Bulk Density 1350C Fire Clay Bricks Insulating Refractory Brick refractory bricks used For steel Furnace show weakly acidic,and the ability of resistance to alkaline slag erosion is poor,but with the increase of the content of Al203,the thermal stability of Yellow Low Bulk Density 1350C Fire Clay Bricks Insulating Refractory Brick refractory bricks used For steel Furnace is better than silica brick, magnesia brick and so on.
Yellow Low Bulk Density 1350C Fire Clay Bricks Insulating Refractory Brick refractory bricks used For steel Furnace is made from clinker clay by mixing, forming, drying, sintering and matching characterized by good resistance to corrosion and abrasion, good thermal shock resistance, good spelling resistance, high mechanical strength, good volume stability under high temperature.
Yellow Low Bulk Density 1350C Fire Clay Bricks Insulating Refractory Brick refractory bricks used For steel Furnace is made of local top grade fireclay materials under the high temperature according to the lasted national standard, which possesses even bulk density, high strength, low thermal conductivity and low impurity.
Advantage
