The chute lining plate should be made of materials with good wear resistance, strong pressure resistance and high temperature resistance, such as high alumina ceramics, silicon carbide ceramics, etc.
Chemshun Ceramics introduce Commonly used types and characteristics of abrasion resistant materials
1). High alumina ceramics
High alumina ceramic is a ceramic material made of high-purity alumina powder as the main raw material and sintered at high temperature. It has the advantages of high hardness, strong wear resistance, good chemical inertness, and high temperature resistance. It is a commonly used material for focus line chute lining boards.
2).Silicon carbide ceramics
Silicon carbide ceramics is a material made of carbon and silicon powder sintered at high temperature. It has the characteristics of high hardness, good wear resistance, strong corrosion resistance, and high temperature resistance. It is an ideal material to prevent tar erosion and extend the life of equipment. A good choice.
3). Zirconia ceramics
Zirconia ceramic is a high-grade ceramic material with zirconia as the main component. It has the characteristics of high hardness, high strength, high temperature strength, and good dimensional stability. However, it is more expensive and is suitable for coking equipment with higher requirements
2：How to choose suitable wear-resistant materials
1). Choose according to the usage environment
According to the characteristics of the use environment, wear-resistant materials with different characteristics are selected. For example, if the equipment needs to withstand harsh environments such as high temperature and high pressure, materials that are resistant to high temperature and pressure should be selected.
2). Choose based on cost
Different materials have different prices, processing difficulties, maintenance costs, etc., so cost factors should be considered when choosing. For coking equipment that needs to be used for a long time, choosing high-wear-resistant but expensive materials is actually a way to save in the long run.
3: Frequently Asked Questions
1). Do the focus line chute linings have to be made of ceramic materials?
Not necessarily, the material should be selected according to the specific use environment. In some cases, other suitable materials can also be used. Currently, alumina ceramic chutes are widely used.
2). How long is the service life of ceramic materials?
The service life varies depending on the use environment, processing methods, material quality and other factors. Usually, under the same conditions, the service life of high-aluminum ceramics and silicon carbide ceramics is longer, while the service life of zirconia ceramics is longer.
