I. Product Introduction
Cast stone is a non-metallic wear and corrosion-resistant material made by melting and casting raw materials such as natural rocks like diorite and basalt or industrial waste slag, along with additives like amphibole, dolomite, and fluorite, and crystallizers like chromite and magnesite. It is processed through processes such as melting, casting, crystallization, and annealing. Its products include plates, bricks, pipes, and various shaped materials. These variously sized plates, pipes, and shaped objects are collectively referred to as cast stone products.
Cast stone molding processes include melt casting, sintering, and hot direct casting. 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, wood, and other materials in many equipment parts, offering high wear resistance and acid-base corrosion resistance that general metals cannot match. It also extends equipment lifespan, 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 exhibits 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 brittle, with high hardness, but its main drawback is its high brittleness, making it unsuitable for承受 heavy impacts.

The cast stone products have a low SiO2 content, but due to their high-temperature melting and subsequent crystallization, a protective layer forms, reducing chemical corrosion to nearly zero. This is the primary reason for the cast stone's high resistance to acid.
Cast stone slabs are categorized into three types: standard, standard irregular, and special irregular. Standard slabs include rectangular, trapezoidal, hexagonal, sector, and circular plates; standard irregular slabs consist of arched plates, chute镶板, slag trench straight groove镶板, etc.; special irregular slabs feature double-curved panels, cone-shaped panels, sieve strips cast stone plates, as well as slag trench curved sections, varying diameters, confluence, Y-junction, and T-junction plates. The extensive range of equipment linings cast stone slabs are all included within the products of the aforementioned categories.
