The range of steel grit used in construction

　　The most obvious construction performance of steel grit is wear resistance, but in addition, it also has other remarkable good properties, which makes iron and steel grit play an important role in today's construction projects.

　　1. Storage silo protection: The physical and chemical effects of materials on the silo wall are various, and the common ones are the impact and wear of materials. In order to save steel as much as possible, in this protective lining design, as far as possible in production, "iron steel sand (construction abrasive)" should be used as the lining material for warehouse wall protection.

　　2. Coal industry beneficiation (washing) coal mine infrastructure project: the wear-resistant layer of the inner wall of the loading coal bunker, the bottom coal bunker, the raw coal bunker, the buffer bunker, the lump coal bunker, the loading and unloading bunker of the collection station, the drain door, the chute, etc.

　　3. Building material industry cement plant infrastructure project: clinker storage, raw material storage, wear-resistant layer on the inner wall of the homogenization storage and the wear-resistant layer on the ground of the gypsum board factory. Metallurgical industry steelworks, sintering plants, rod (wire) material factory infrastructure projects: raw material warehouse floor, finished product warehouse floor, sintering tank, sedimentation tank, slag ditch and other concrete wear-resistant layers. Power industry coal handling system: wear-resistant layer on the inner wall of silos and funnels.

　　4. Chemical industry coking plant, calcium carbide plant, chlorine plant and various chemical industry warehouse infrastructure projects: silos, funnels, wear-resistant layers on the inner walls of batching ore tanks.

　　5. Infrastructure projects of hydropower stations: flood discharge tunnels, flood diversion tunnels, and concrete wear-resistant layers on river slopes.

　　6. Basic engineering of transportation and navigation: high-strength concrete wear-resistant layers such as ports, docks, bridges, roads, and airport runways.
