Calendered Microcrystalline Cast Stone Liners

Cast stone lining board is a kind of processed silicate crystalline material, using natural rocks (basalt, gabase and other basic rocks, as well as shale) or industrial waste slag (blast furnace slag, steel slag, copper slag, chromium slag, ferroalloy slag, etc.) as the main raw material, by battering, melting, pouring, heat treatment and other processes made of crystal arrangement is regular, hard, delicate non-metallic industrial materials. The cast stone has abundant resources, simple production process, low cost and excellent wear resistance, corrosion resistance and other properties.

The forming process of cast stone is divided into three categories: dissolution casting, sintering forming and hot direct sintering casting. At present, cast stone products have been widely used in building materials, chemical industry, metallurgy, mining and other industrial sectors. In many parts of the equipment cast stone is steel, iron, lead, rubber, wood and other ideal replacement materials, with the general metal can not reach high wear resistance, acid and alkali corrosion resistance, and has the advantages of extending the use of equipment cycle, reduce maintenance hours, improve production efficiency, reduce product costs and so on. Cast stone has been used in anti-corrosion engineering for decades. The cast stone has the characteristics of tight structure, small water absorption, high compressive strength and good wear resistance. In addition to the hot phosphoric acid, hydrofluoric acid and soluble alkali above 30℃, almost all inorganic acids, organic acids, alkali, salt, water and organic solvents have good corrosion resistance, cast stone is a brittle material, with high hardness, casting stone disadvantage is brittleness, not easy to withstand the impact of heavy objects.
