Characteristics and application of wear-resistant refractory castable

Wear-resistant and refractory castable is a kind of industrial equipment used in high temperature environment. The main components of wear-resistant and refractory castable include alumina, silicon carbide, magnesium oxide, silicate and other materials, which have good wear resistance and fire resistance. Properties of monolithic refractories. The following is an introduction to the characteristics and applications of wear-resistant refractory castables.
First, the characteristics of wear-resistant refractory castables
1. Good high temperature resistance: Wear-resistant refractory castables can maintain stable physical and chemical properties in high-temperature environments, and are not easy to melt and flow.
2. Good wear resistance: Wear-resistant refractory castables have excellent wear resistance and can withstand various wear methods such as mechanical wear and airflow erosion.
3. Good corrosion resistance: wear-resistant refractory castable has excellent wear resistance, which can effectively reduce the wear and peeling of the material surface.
4. Good stability: wear-resistant refractory castable has good stability, and it is not easy to crack and drop.
5. Convenient construction: wear-resistant refractory castables can be constructed by pouring, vibrating, etc., and the construction is simple and convenient.
6. Wide range of applications: Wear-resistant refractory castables are suitable for various high-temperature equipment and internal linings of furnaces, such as cement kilns, steel furnaces, chemical reaction kettles, etc.

Second, the scope of application of wear-resistant refractory castables
1. Iron and steel industry: Wear-resistant and refractory castables are used for lining and repairing of high-temperature equipment such as steelmaking furnaces, converters, electric arc furnaces, intermediate frequency furnaces, continuous casting machines, rolling mills, heating furnaces, and annealing furnaces in steel plants.
2. Cement industry: Wear-resistant refractory castables are used for the protection and maintenance of high-temperature parts such as rotary kilns, kiln shells, kiln heads, and kiln chambers in cement plants.
3. Chemical industry: Wear-resistant and refractory castables are used for internal protection and repair of high-temperature, high-pressure, high-wear and corrosive parts such as chemical reaction kettles, storage tanks, pipelines, and equipment.
4. Electric power industry: Wear-resistant and refractory castables are used for internal protection and repair of high-temperature, high-pressure, high-wear parts such as power plant boilers, dust collectors, fans, guide vanes, and containers.
5. Mining and metallurgical industries: used for internal protection and repair of high-temperature, high-pressure, high-wear equipment such as ball mills, ore grinding machines, flotation machines, magnetic separators, and copper smelting furnaces in mineral processing plants.
6. Glass industry: Wear-resistant refractory castables are used for protection and repair of high-temperature parts such as glass kilns and FRP molds.
It should be noted that although the wear-resistant refractory castable has good performance, its price is relatively high, and the construction is difficult at the same time, requiring professional technical and equipment support, so it needs to be evaluated and selected according to the actual situation when using it.
