Calendered microcrystalline board product is a new type of protective material and architectural decoration board with high strength, high wear resistance and corrosion resistance, which is made by melting, calendering, crystallization, annealing and other processes with various minerals or slag as raw materials. The main difference between the rolled microcrystalline plate and the cast stone plate is that the cast stone plate is made of naturally formed diabase and basalt as raw materials, and the thickness of the cast stone plate can reach 20 mm and 30 mm. The thickness of the rolled microcrystalline plate is from 12 to 20 mm. In most cases, only about 14 mm thickness can be used to meet the actual needs, and the weight is only 1 / 3 of that of steel. Therefore, the internal volume of the warehouse body can be relatively increased, and the weight of the equipment and the warehouse body can be reduced.

The calendered microcrystalline plate is mainly used in the following aspects :

1. the power generation industry unloading ditch, coal hopper, coal bunker, dry coal grid, car dumper, slag machine, water treatment, etc.
2. the chemical industry anti-corrosion ground, pump base, etc.
3. The wear-resistant lining board in gangue bin, medium barrel, scraper, bucket lifter, chute, sieve funnel and so on in the coal industry.
4.  the iron and steel industry blast furnace mixing silo, sintering silo, feeder, ball machine, etc.
