Microcrystalline cast stone based on a variety of slag as the main raw material, melting, calendering, crystallization, annealing and the formation of a high strength and high corrosion resistance of new high-tech industrial protective materials and building decoration materials. Widely used in silos, hopper, chute, scraper, surface treatment and other parts of the coal, steel, electricity, chemicals, non-ferrous metallurgy and other industries. Meanwhile, as the building decoration materials, its clean and beautiful, beautiful, no color, no morals, no radioactive contamination, is a green building materials. High wear resistance, corrosion resistance, impact resistance, thin sheet, flat surface, size large, cutting, easy construction, environmental protection, non-radioactive contamination, high brightness. Unloading can be used in the power generation industry ditch, coal bucket, Front warehouse, dry coal gate, dumper, slag, water treatment and so on. Can be used in the chemical industry, anti-corrosion ground, pumps and other infrastructure. Can be used for wear-resistant lining of the coal industry waste rock storage medium barrel, scraper, bucket elevator, chute, hopper, etc. within the next screen. Can be used in steel industry blast mixing positions, firing hopper, feeder, Ball machines. Microcrystalline cast stone plate has a P-shaped, general contour, special profiled three categories. Among them, the P-shaped plates have a rectangular plate, trapezoidal panels, hexagonal plates, fan-shaped plate, round plates, etc; P shaped board has curved panels, chute paneling, straight ditch ditch ash paneling; special shaped board has : hyperbolic panels, tapered panel, screen grate cast stone and ash ditch ditch bends, reducers, confluence, two fork, Crossroads board. Range of cast stone lining equipment are included in the above categories of products included.
