Description
LG1.0 High Alumina Insulation Refractory Brick Insulating Product Big Size
The Description:
Heat insulation brick is a kind of heat insulation product with regular shape. It belongs to light insulation refractory material. The common characteristics of such materials are small volume density, light bulk weight and low thermal conductivity. But the strength is low, high temperature reburning shrinkage is large, heat insulation, moisture effect is good.

Product feature:
Due to its high porosity, low volume density and good thermal insulation properties, lightweight thermal insulation bricks are widely used as thermal insulation filling materials in the space between refractory bricks and ketone bodies inside various industrial kilns to reduce the heat loss of the kiln and obtain high energy utilization efficiency. The melting point of antrite is 1550ºC, which has the characteristics of low density, low thermal expansion coefficient, low thermal conductivity, stable existence in a reducing atmosphere, etc., and can partially replace the clay, silica and high aluminum refractory materials at the working temperature of 1000-1300ºC, and achieve energy saving and emission reduction. There are few single anorthite in nature, and some synthetic anorthite refractories have been reported. Why choose us? Zhengzhou Kaiyuan Refractories Co., Ltd is a manufacturer of silicon-aluminum refractory (fireclay brick, high alumina brick, silica brick, mullite brick, corundum brick, insulation brick, castable, mortar) for coke oven, blast furnace, hot blast stove, heating furnace, anode baking furnace, boilers and other industrial furnaces for 20 years located in Henan, China. Our total annual production capacity is about 100,000 tons of dense-shaped refractory product, and 100,000 tons of monolithic refractory product.
We have three tunnel kilns for silicon-aluminum dense bricks and one new plant for the monolithic refractory.
