Application Value of Refractory Material

Date:2016-12-23 17:23 From:Zhengzhou Sunrise Refractory Author:admin
Refractory brick, as the important industrial product, has the performances of good heat resistance ability, large volume density, strong shock resistance.

Usually, refractory brick generally is divided into two types, namely unshaped refractory materials and finalize refractory materials. According to different material ingredients, and

can be divided into five categories, namely silica alumina refractory brick, alkaline series refractory brick, carbonic refractory brick, zirconium refractory brick, thermal insulation

refractory brick.

Refractory brick is to use refractory clay or refractory raw materials firing into the refractory materials. Light yellow or brown. Magnesia  brick has a certain shape and size of

refractory materials. According to the preparation process method, can be divided into the burnt brick, unburned brick, fused brick (fused cast brick), fire-resistant insulating

brick. According to the shape and size, can be divided into standard brick, ordinary brick, special-shaped brick, etc.

Refractory brick can be used as building kiln and high temperature construction materials and structural materials of many thermal technology equipment, and can withstand

various physical and chemical changes in the heat and mechanical action. Such as refractory fireclay brick, high alumina brick, silica brick, magnesia brick, etc. Refractory rick is

one of the most widely used in refractory products, and what features does it have?

1. Chemical composition: the main ingredient decided the quality of refractory brick and characteristics.

2. Volume density: unit volume weight, density is big, shows that the compactness of refractory brick is good, the strength is likely to be high, but the coefficient of thermal

conductivity could be big.

3. Apparent porosity: without specific requirements, but must strictly control the porosity.
