High alumina clay checker refractory bricks for HBS has a plurality of through-holes, which are parallel to each other with the side surfaces, and locating projections and locating grooves on two parallel surfaces.
Raw material of tundish nozzle brick:Corundum&graphite,chrome&corundum,magnesia sand&bauxite,additive.
Features and advantages:Good thermal stability.High strength resistance to corrosion.
B series insulation bricks are made from high purity raw material according to different brick type to meet different requirement.They are ideal thermal insulation material usually used in industrial furnaces and heating pipe.
Refractory castable is one of the unshaped refractory materials.It is made of refractory aggregate . refractory powder . binders and other additives. It is loose, No fixed shape,Has high liquidity, Casting and vibration molding,Can use directly or use after add appropriate water or other liquid. It is one of the new type refractory material of don't need calcination.
