1. Cast stone Plate Products

Cast stone is a natural rocks such as diabase, basalt or industrial waste as raw material, adding some additional agents such as angle head rock, dolomite, fluorite crystallization agents such as chromite, titanium, magnesium ore through melting, casting a non-metallic, crystalline and annealing processed to corrosion-resistant materials. Cast stone products have boards, bricks, pipes and all kinds of special materials, the variety of sheet metal, pipes, shaped object system called cast stone products.

Cast cast molding process are soluble type, sintering, hot direct burning cast type and other categories. Currently cast stone products have been widely used in building materials, chemical industry, metallurgy, mining and other industrial sectors. In some parts of many devices cast stone is steel, iron, lead, rubber, wood and other materials instead of the ideal, with the general metals reach highly wear-resistant, acid and alkali resistance, and has a device used to extend the period when reducing the maintenance man, increase productivity, reduce product cost. Cast stone taught early in the application of anticorrosion, are decades old. Cast stone with a compact, small water absorption, high compressive strength, good wear resistance characteristics. In addition to above 30 hot phosphoric acid, hydrofluoric acid and an alkali solution outside, almost all have good resistance to corrosion of inorganic acids, organic acids, bases, salts, water and organic solvents, etc., belong to the brittle material cast stone , having a high hardness,

Cast stone Disadvantages: It is brittle and difficult to withstand heavy impact.

SiO2 content of cast stone products is not high, but because it melted at high temperatures, after the formation of a crystalline layer of protective film, and finally the chemical corrosion media tends to zero, which is the main reason why the cast stone can bear highly acid.

2. The cast stone type:

cast stone plate there are ,normal one,normal- profiled , special profiled three categories. S & P has a rectangular plate-shaped plate, trapezoidal panels, hexagonal plates, fan-shaped plate, round plates, etc; P shaped board has curved panels, chute paneling, straight ditch ditch ash paneling; specially shaped boards are: 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.

3. The use of cast stone

1, Power generation industry: coal unloading chute, coal hopper, storage bunker, dry coal gate, dumper, slag, water treatment and so on.

2, Chemical industry: corrosion ground, pumps and other infrastructure.

3, Coal industry: wear liner waste rock storage medium barrel, scraper, bucket elevator, chute, hopper, etc. within the next screen.

4, Steel industry: blast mixing positions, firing hopper, feeder, Ball machines.
