What is refractory material?

Source: Network

Refractory material, as the name implies, is that this material can reach the fire resistance level, endure a certain temperature, and have a very wide range of use.

What are 1. refractory materials?

1. It is a non-metallic material that can withstand high temperatures. Generally speaking, it is an inorganic material, and its refractoriness can exceed 1580 degrees. It has the functions of high temperature resistance, deformation resistance and erosion resistance. Refractoriness refers to its thermal melting, this material softens to a certain extent, the formation of the temperature is a physical index.

2. Its main components are natural raw materials or some waste residues, including synthetic materials and recycled materials. Later, it needs to be made by different processes and cast by sintering or casting.

Classification of 2. refractory materials

1. If there are two kinds of stereotypes and stereotypes according to it, one is refractory bricks, such as clay type or carbon bricks, which have refractory effects. There is a kind of amorphous, refractory cement or refractory slurry, including plastic, which is not solid, called amorphous refractory.

2. If it is divided according to its performance, there is a refractory material with heat insulation and thermal insulation performance, which is more suitable for the installation of external walls. For example, vacuum insulation board or fiber adhesive, and fiber blanket, used for indoor partition refractory brick.

3. If it is divided according to its chemical composition, some chemical compositions are acidic or neutral, and some are alkaline.

4, if according to its chemical composition content to divide, some materials contain alumina or carbon, chromium elements.

5. If there are many divisions according to its raw materials, some use refractory clay, made of refractory bricks or spinel, steel jade, dolomite, etc.

6. If divided according to the industry, the ceramic industry includes the glass industry or the heating industry, and the steel industry, there are refractory materials.
