Wear-resistant ceramic composite lining plate

I. Product Introduction
Cast stone is a non-metallic wear and corrosion-resistant material made by processing natural rocks such as diorite and basalt, or industrial waste slag, with additives like amphibole, dolomite, and fluorite, and crystallizers such as chromite and magnesite, through processes like melting, casting, crystallizing, and annealing. Its products include plates, bricks, pipes, and various non-standard materials. These variously sized plates, pipes, and non-standard objects are collectively referred to as cast stone products.
Cast stone forming processes include melt casting, sintering, and hot direct casting. Currently, cast stone products are widely used in construction materials, chemicals, metallurgy, mining, and other industrial sectors. Cast stone is an ideal substitute for steel, iron, lead, rubber, and wood in many equipment parts, offering high wear resistance and alkali-resistance not achievable by general metals. It also prolongs equipment lifespan, reduces maintenance time, improves production efficiency, and lowers product costs. Cast stone has a history of early application in anti-corrosion engineering, spanning several decades. It features a dense structure, low water absorption rate, high compressive strength, and good wear resistance. It exhibits excellent corrosion 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 brittle with high hardness, but its major drawback is its brittleness, making it unsuitable for承受 heavy impacts.

The SiO2 content in cast stone products is not high, but due to its high-temperature melting process, it forms a protective layer upon crystallization, making chemical corrosion of the medium negligible. This is the primary reason why cast stone is highly acid-resistant.
Cast stone slabs are categorized into three main types: common, common irregular, and special irregular. Common slabs include rectangular, trapezoidal, hexagonal, sector, and circular shapes; common irregular slabs consist of curved slabs, chute lining slabs, slag channel straight groove lining slabs, etc.; special irregular slabs feature double-curved panels, conical panels, sieve strips of cast stone, as well as slag channel bend, variable diameter, junction, Y-split, and T-split slabs. All types of equipment lining cast stone slabs are included within the products of these categories.
