Product Description
The dovetail slotted ceramic liner is to fix the dovetail alumina ceramics to the equipment that needs anti-wear through carbon steel or stainless steel guide rails. When using, weld the dovetail guide rail to the parts that need anti-wear, and control the spacing to ensure the gap between the ceramics. The dovetail alumina ceramic will then be threaded into the rail to complete the installation.
Product Features
Dovetail alumina ceramics have the characteristics of high-temperature resistance, non-shedding, and long service life. You can choose ceramics of various thicknesses according to wear conditions, and customize various special-shaped structures to form impact-resistant and wear-resistant layers that meet specific equipment.

Scope of application
-It is widely used in thermal power, steel, smelting, machinery, coal, mining, chemical, cement, ports, and other enterprises in coal transportation, material conveying systems, pulverizing systems, ash discharge, dust removal systems, and other high-wear machinery and equipment.
-It is used for anti-wear of the high-temperature flue of power plants, waste heat power generation pipeline of cement plants, sintering and dust removal equipment pipeline of steel plants, etc. It has an irreplaceable role in both high- and low-- temperature environments.
-Cement plants are one of the most widely used industries for wear-resistant materials. The powder station, cyclone separator, V-type separator, recirculation fan, waste heat power generation system pipeline, grate cooler to dust collector pipeline, mill, and other equipment are all applied to wear-resistant materials. Because dovetail alumina ceramics liners are easy to install and inexpensive, they are highly recommended for cement plants.
-It is used in the denitration flue and deflector, coal mill shell, coarse and fine powder separator, pulverized coal pipeline, burner, hot air duct, circulating fluidized bed boiler, and other equipment in power plants. The properties of the wear layer reduce unplanned plant downtime and reduce the risk of equipment leaks. The dovetail wear-resistant ceramics produced by our company are also used in chemical, smelting, mining equipment, and other industries.
Technical characteristics
Alumina corundum ceramic has high strength, high hardness, and super wear resistance. It can be glued, welded, and fixed and has the advantage of being impact-resistant. The density of this material is 3.6g/cm3, which is half that of steel. It is lightweight, which greatly reduces the load on the equipment. In addition, it is easy to install, saving time and effort.
