Refractory castables are produced from refractory aggregates, refractory powders, binders and other additives and can use directly or use after adding appropriate water or other liquid. Refractory castable is used as lining turning kiln, hot converter lining heat treatment furnace, furnaces of metallurgy industry, chemical industry and construction industry, circulation part of furnaces. Characteristics High refractoriness, high refractoriness under load. High density, low porosity. Good slag resistance and corrosion resistance. High strength and wear resistance. Good resistance to flake performance. Good thermal shock stability. Scouring resistance. Long service life
