Wear-resistant ceramic lining plate

I. Product Introduction
Cast stone is a non-metallic abrasive and corrosion-resistant material made by processing natural rocks such as diorite, basalt, or industrial waste slag. It involves adding certain additives like amphibole, dolomite, and fluorite, along with crystallizing agents such as chromite and magnesite, through processes like melting, casting, crystallization, and annealing. The products include plates, bricks, pipes, and various non-standard materials. These materials of various specifications, such as plates, pipes, and non-standard objects, are collectively referred to as cast stone products.
The casting stone forming process includes three types: melt casting, sintering, and hot direct casting. Currently, casting stone products are widely used in construction materials, chemicals, metallurgy, mining, and other industrial sectors. Casting stone is an ideal substitute for steel, iron, lead, rubber, wood, and other materials in many equipment parts, offering high wear resistance and acid-base corrosion resistance that general metals cannot achieve. It also extends the service life of equipment, reduces maintenance time, improves production efficiency, and lowers product costs. Casting stone has been used in anti-corrosion engineering for decades, and it features a dense structure, low water absorption rate, high compressive strength, and good wear resistance. It has excellent corrosion resistance to almost all inorganic acids, organic acids, bases, salts, water, and organic solvents, except for hot phosphoric acid above 30℃ and alkali solutions. Casting stone is a brittle material with high hardness, but its drawback is its high brittleness and difficulty in withstanding impacts from heavy objects.

The cast stone products have a low SiO2 content, but due to the high-temperature melting process, a protective layer forms upon crystallization, reducing chemical corrosion of the medium to nearly zero. This is the primary reason for the cast stone's high resistance to acid.
Cast stone slabs are divided into three main categories: general, general irregular, and special irregular. General slabs include rectangular plates, trapezoidal plates, hexagonal plates, sector plates, circular plates, etc.; general irregular plates consist of curved plates, trough lining plates, slag channel straight channel lining plates, etc.; special irregular plates feature double-curved plates, cone-shaped plates, sieve strips of cast stone plates, as well as slag channel bends, variable diameter plates, junctions, bifurcation plates, and trifurcation plates. The cast stone plates for numerous equipment linings are all included within the products of these categories.
