Cast stone
close Cast stone Cast stone is a kind of processed silicate crystal material, which uses natural rock (basalt, diabase and other basic rocks, and shale) or industrial waste slag (blast furnace slag, steel slag, copper slag, chromium slag, ferroalloy slag, etc.) as the main raw materials, and is made of regular crystal arrangement, hard texture Fine non-metallic industrial materials. Cast stone has good corrosion resistance and wear resistance. Its acid and alkali resistance can reach more than 99%. Its wear resistance is 5~10 times higher than that of manganese steel and several times higher than that of carbon steel; Its Mohs hardness is 7~8, second only to diamond and corundum. But its toughness and impact resistance are poor, and it is difficult to cut. Cast stone products mainly include cast stone pipes, cast stone composite pipes, cast stone slabs and cast stone materials, which have been widely used in the severely worn and corroded parts of power, coal, mining, metallurgy, chemical industry, construction and other industrial sectors, such as the bottom lining of scraper conveyor, chute lining, fan shell lining, mill feeding and discharging device and other parts. The service life of components or equipment can be extended by more than ten times or even dozens of times than that of other materials. In construction, it can be used as the warehouse floor, and the corridor and stair step of public buildings, with low cost and particularly excellent wear resistance, corrosion resistance and other properties. The acid resistant floor and dado of the powerhouse, as well as the dam facing and sand discharge hole lining of hydraulic engineering. Light or colored cast stone can replace marble and granite as interior and exterior decoration materials and floor materials. Due to the poor toughness and high hardness of the cast stone products, it is difficult to cut and process them. Generally, the products are processed according to a certain shape and size. The fixing method is masonry and inlay.
