Expanding the Applications and Improving the Efficiency of Steel Grit

　　Steel grit is primarily used for weight distribution and wear resistance, and it is widely used in construction.

　　Steel grit has distinct characteristics: high grade, uniform particle size, high hardness, non-pulverizing specific gravity, and a dark iron red or blackish-red color. It is not only wear-resistant, compressive-resistant, and impact-resistant, but also possesses properties such as moisture resistance, acid and alkali corrosion resistance, and high-temperature resistance, making it widely used in construction.

　　Concrete wear-resistant layers or mortar wear-resistant layers made with steel grit exhibit superior compressive strength, splitting tensile strength, and coefficient of friction compared to iron filings mortar wear-resistant layers. Iron filings are prone to corrosion and flaking, while steel grit does not. Compared to diabase cast stone, steel grit is not only cheaper and easier to apply, but its impact strength and brittleness value are approximately twice that of diabase cast stone.

　　Therefore, for decades, iron-steel grit has been widely used as the wear-resistant layer in concrete or mortar for industrial infrastructure projects in my country, including coal mines, power plants, chemical and metallurgical plants, warehouses, docks, loading and unloading machinery factories, parking lots, electronics industries, highways, textile industries, and military industries. This is for applications involving heavy friction, easy damage, and high impact.

　　Applications of steel grit in construction:

　　1. Coal chemical infrastructure: Wear-resistant layer for the inner walls of various coal bunkers, hoppers, chutes, etc.; wear-resistant layer for the surface of coal pillars, beams, etc.

　　2. Thermal power plant infrastructure: Wear-resistant layer for coal conveying systems such as coal bunkers, hoppers, and unloading ditches; wear-resistant layer for the inner walls of dry ash silos, etc.

　　3. Coal coking and steel infrastructure: Wear-resistant layer for mine bins, coal receiving pits, coke bins, hoppers, etc.

　　4. Cement industry infrastructure: Wear-resistant layer for various hoppers, silos, material pits, bulk storage silos, etc.

　　5. Water conservancy and hydropower infrastructure: Impact-resistant, wear-resistant, and corrosion-resistant layer for spillways, diversion tunnels, overflow dam surfaces, and locks, etc.

　　6. Base layers, In civil buildings: stair treads and anti-slip strips; wear-resistant flooring in underground garages and parking lots;

　　7. In metallurgical and chemical infrastructure: wear-resistant layers for hoppers, silos, and chutes in various mineral processing and chemical industries;

　　8. In other infrastructure: such as heavy truck storage areas and large machine tool workshops requiring dust control in high-precision technology processing and production, workshops with heavy machinery and equipment pressure, and places prone to oil spills, requiring oil resistance, anti-slip, and wear resistance.

　　From this, we can see how important the proper use of steel shot is. Everyone should study this carefully.
