What does the wear resistance of refractory bricks have to do with?
Refractory brick is a typical refractory material. We need to test all aspects of the product during the production process. Since this product is mostly used for the construction of engineering walls, the requirements for its own wear resistance are relatively High. If you want to improve its wear resistance, you must first remove the factors that affect the product’s wear resistance. Then the question is, what does the wear resistance of refractory bricks have to do with it?
The abrasion resistance of refractory bricks depends on its own composition and structure. When the product is composed of dense polycrystals composed of a single crystal, its abrasion resistance mainly depends on the hardness of the mineral crystals that make up the material. High hardness, high wear resistance of the material. When the mineral crystals are non-isotropic, the crystal grains are fine and the wear resistance of the material is high. When the material is composed of multiple phases, its wear resistance is directly related to the bulk density or porosity of the material, and is also related to the bonding strength between the components.
Therefore, for a certain type of brick at room temperature, its abrasion resistance is proportional to its compressive strength. If the manufacturer considers the above factors when sintering the refractory bricks, the products produced have better abrasion resistance. In addition, the wear resistance of the product is related to the temperature during use. Some products, such as high alumina bricks, are generally considered to be at temperature (such as within the elastic range below 700-900℃). The higher the temperature, the lower the wear resistance. It can be considered that when the temperature increases, the wear resistance decreases as the elastic modulus of the brick increases.
First of all, people can also know the chemical composition of this material. Because refractory brick factories are still very popular in people’s lives. And we all know that its main components determine the quality and characteristics of the refractory. Generally speaking, the raw materials of refractory materials come from many refractory materials. Therefore, we are starting to apply these raw materials more and more in our lives.
Secondly, we also know that it has special characteristics such as bulk density. Because such refractory bricks need to withstand a very high temperature experience, people also need them to work normally at high temperatures. Therefore, the weight per unit volume has a high density, which means that the compactness of the refractory brick is good, and the strength it brings may be high.
Later, refractory bricks also have higher requirements for the porosity. But nowadays, people need to make specific requirements in the industrial production process, but as a manufacturer, they strictly control the visible pores and have very high quality. On the other hand, the thermal shock resistance of this material is very good, and its ability to resist sudden changes in temperature without being destroyed.
It can bring too many benefits to people. There are a lot of new chemical materials in people’s lives, and these are to make people’s material life better. Refractory material Refractory brick is an indispensable material in industrial production. Refractory material is a very stable chemical property.
