Widely used in ceramic roller kiln, shuttle kiln, cracking furnace, hot blast furnace and all kinds of electric furnace lining, furnace door brick, kiln car brick, etc. The advantages are high purity, low impurity content, high temperature resistance, direct contact with flame, resistance to various atmosphere corrosion, low thermal conductivity, low hot melt, high strength, and excellent thermal shock resistance, high dimensional accuracy, can be cut arbitrarily. Body density according to user requirements can be between 0.5 0.6 0.8 0.9 1.0 1.2 1.5, acting on high temperature kiln direct contact with the flame, good thermal insulation effect, high compressive strength, low thermal conductivity. It is suitable for heat preservation of electric kiln, all kinds of high temperature rotary kiln, tunnel kiln, gas nitride kiln, etc. The crystallization of fused mullite is larger than that of sintered mullite, and the thermal shock resistance is better than that of sintered products. Their high temperature performance mainly depends on the content of alumina and the uniformity of the distribution of mullite phase with glass. 1400 degree mullite brick is mainly used in hot blast furnace top, blast furnace body and bottom, glass furnace regenerator chamber, ceramic sintering kiln, dead corner lining of petroleum cracking system, etc.

JM23 light mullite brick is, is the introduction of new technology in China, the latest type of high temperature energy-saving light refractory material. Light mullite brick quality light insulation effect is good, is a high-quality high purity refractory powder, according to the product requirements of the proportion, adding organic composite filler, vacuum extrusion molding, high temperature sintering synthesis of light mullite products, our company's production of light mullite brick according to different specifications, alumina content in 50%-80% range.
