Refractory Brick

Thermal insulation refractory can also be called lightweight refractory, and is also often called thermal insulation material. It is widely used in the insulation layer of industrial kiln. There are many varieties and classifications of heat insulation and refractory materials. There are light clay bricks, light silica bricks, light high alumina bricks, mullite poly light bricks, alumina hollow ball bricks, high alumina poly light bricks, etc. Light brick has stable performance and convenient use, transportation and storage. According to the temperature classification, the insulation refractory materials are divided into low temperature insulation materials (< 600 Celsius), medium temperature insulation materials (600 ~ 1200 Celsius) and high temperature insulation materials (> 1200 Celsius). In terms of bulk density, the bulk density of commonly used lightweight insulation refractory materials is 1.0 ~ 1.2 g/cm3, and 0.3 ~ 0.6 g/cm3 is called ultra-lightweight insulation materia

The prefabricated slide rail brick for heating furnace is prepared from brown corundum particles, chromium corundum particles and powders, white corundum powder, alumina powder, pure calcium aluminate cement, silicon micro powder and composite water reducing agent according to a certain proportion, evenly mixed and prefabricated into brick blocks, and then the refractory bricks are dried in a drying room at 200 Celsius and cooled naturally to obtain finished bricks, The production process is simple, which reduces the labor intensity of workers; the raw material gradation is reasonable, the cement hydration in water, the materials can achieve the closest accumulation, and get high strength and low porosity refractory brick ; the prefabricated brick blank does not need to be fired at high temperature, which can save energy and reduce consumption, reduce pollution. At the same time, the strength of the finished slide rail brick can be improved and the service life of the slide rail can be
