It mainly depends on the working conditions, each has its own advantages. Cast stone is heavy and has lower wear resistance than wear-resistant ceramics.
Let’s talk about wear-resistant ceramics first. Ceramic-lined pipes are manufactured using a high-tech production process - self-igniting high-temperature clutch synthesis. The tube is composed of three layers: corundum ceramic, transition layer, and steel from the inside to the outside. The ceramic layer is formed into dense corundum porcelain (AL2O3) at a high temperature above 2200°C, and forms a strong bond with the steel pipe through the transition layer. Composite pipes take full advantage of the high strength, good toughness, impact resistance, and good welding performance of steel pipes and the high hardness, high wear resistance, corrosion resistance, and good heat resistance of corundum porcelain to overcome the low hardness, poor wear resistance, and poor toughness of ceramics. characteristics. Therefore, the composite pipe has good comprehensive properties such as wear resistance, heat resistance, corrosion resistance, resistance to mechanical and thermal shock, and good weldability. It is an ideal wear-resistant and corrosion-resistant pipeline for conveying granular materials, grinding, corrosive media, etc.
Because the pipe has wear-resistant, corrosion-resistant and heat-resistant properties, it can be widely used in electric power, metallurgy, mining, coal, chemical and other industries to transport sand, stone, coal powder, ash and slag, aluminum It is an ideal corrosion-resistant pipe for abrasive particulate materials and corrosive media such as liquids.
Let’s talk about casting stone.
Cast stone products mainly include cast stone pipes, cast stone composite pipes, cast stone slabs and cast stone materials. They have been widely used in severe wear and tear in industrial sectors such as electric power, coal, mining, metallurgy, chemical industry, and construction. Corroded parts, such as scraper conveyor bottom lining, chute lining, fan shell lining, mill inlet and outlet device, etc. It can extend the service life of components or equipment by more than ten times or even dozens of times that of other materials. Because cast stone products have poor toughness and high hardness, they are difficult to cut and process. Products are generally processed into certain shapes and sizes. Its fixing method adopts masonry and inlay methods. [1]?
The main use of cast stone is as anti-corrosion and wear-resistant materials in industry, such as anti-corrosion linings of acid and alkali storage tanks, reaction tanks, and pickling tanks (tanks); Chutes and conveying pipes for various ores, ash and tailings, as well as wear-resistant linings for ball mills, etc. In construction, it can be used as warehouse floors, aisles and stair treads in public buildings, acid-resistant floors and dado skirts in factories, and dam veneers and sand discharge hole linings in hydraulic engineering projects. Light-colored or colored cast stone can replace marble and granite as interior and exterior decoration materials and floor materials. [1]?
Cast stone materials are mainly used in building materials equipment to replace metal material wear-resistant parts that are not subject to impact. Such as belt conveyor rollers, screw conveyor inner cavity, mixer inner surface, air selection hammer crusher air duct inner wall, pneumatic conveying pipe lining, etc.
