Refractory Bricks

The effects of high alumina brick

Aug 09,2017
High alumina brick is the most commonly used refractory materials, widely used in steelmaking, iron, kilns and so on. The quality of high-alumina brick directly affects its many properties, such as high temperature, etc., today Xiaobian to introduce the impact of high alumina brick quality factors, hope that through this study can help you in general , According to the high alumina brick in a variety of chemical composition of the content and its role, it is divided into the main components, impurities and external components of three categories.
The main component of high alumina bricks is the chemical composition that accounts for the vast majority and plays a decisive role in the high temperature properties of the material. Why can high alumina bricks have excellent resistance to high temperature performance, and many refractory materials have their own characteristics? Completely or substantially based on the content of various chemical components in the refractory material and its role, usually divided into the main components, impurities and external components of three types.
Impurities are chemical constituents that are different from the main component in the refractory material and have a low content and are resistant to the high temperature properties of the high alumina bricks. This chemical composition is mostly from the main ingredients of the raw materials entrainment.

The main component of the high alumina brick is the most important chemical component that plays a decisive role in the high temperature properties of the material. The reason why high alumina bricks have a good resistance to high temperature performance, and many refractory materials have their own characteristics, completely or basically depends on the main component.
