Wear-resistant ceramic lining plate

I. Product Introduction
Cast stone is a non-metallic wear and corrosion-resistant material produced by processing raw materials such as natural rocks like basalt and andesite or industrial waste slag. It involves adding certain additives like amphibole, dolomite, and fluorite, along with crystallizers like chromite and magnetite, through processes such as melting, casting, crystallization, and annealing. The products include plates, bricks, pipes, and various non-standard materials, which are collectively referred to as cast stone products.
The casting stone molding process includes three types: solution casting, sintering, and hot direct casting. Currently, cast stone products are widely used in construction materials, chemical industry, metallurgy, mining, and other industrial sectors. Cast 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. Cast stone has been used in anti-corrosion engineering for decades, characterized by its dense structure, low water absorption rate, high compressive strength, and good wear resistance. It has excellent resistance to almost all inorganic acids, organic acids, alkalis, salts, water, and organic solvents, except for hot phosphoric acid above 30℃ and alkali solutions. Cast stone is a brittle material with high hardness, but its main drawback is its high brittleness, making it unsuitable for 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 to nearly zero. This is the primary reason for the cast stone's high resistance to acid.
Cast stone plates are divided into three main categories: common, common-irregular, and special-irregular. Common plates include rectangular, trapezoidal, hexagonal, fan-shaped, and round plates; common-irregular plates have curved, trough lining, and slag channel straight channel lining plates; special-irregular plates feature double-curved panels, cone-shaped panels, sieve bar cast stone plates, as well as slag channel bends, variable diameter, junction, bifurcation, and trifurcation plates. A wide range of equipment linings cast stone plates are included in the products of these categories.
