Refractory brick for hot air furnace
The invention discloses a refractory brick for a hot air furnace and relates to the technical field of refractory material manufacturing. The refractory brick consists of the following raw materials in parts by weight: 40-50 parts of alumina clinker, 15-20 parts of silicon carbide powder, 10-15 parts of silicon nitride powder, 20-30 parts of magnesia and 5-8 parts of paper pulp waste liquid; and the refractory brick for the hot air furnace is prepared by the steps of dosing, mixing, ageing, blank making, drying and firing. Compared with the prior art, the refractory brick disclosed by the invention has the advantages of corrosion resistance, high temperature resistance, strong compressive strength and good thermal shock resistance; and moreover, cracks do not appear easily in the using process of the refractory brick for the hot air furnace, and thus the service life is prolonged.
