High Quality Refractory Brick High Aluminum Insulating Brick

1.Product introduction of high aluminum insulating brick

High aluminum insulating bricks are characterized by high temperature strength, corrosion resistance to various atmospheres, excellent thermal shock stability, good thermal insulation performance, and remarkable energy-saving effect.
High aluminum insulating bricks produced by taking blast furnace materials as the main raw materials, supplemented by appropriate additives, and adopting the polymer light burning loss method. The utility model has the advantages of high strength, good thermal stability, little change in re burning fiber, small thermal conductivity, significant energy saving effect, etc. It is widely used in metallurgy, machinery, ceramics and chemical industries.
