　　The raw material for steel grit is scrap steel of high carbon steel or alloy steel. Firstly, the scrap steel is placed in an intermediate frequency furnace for high-temperature heating to melt it. It needs to be inspected by instruments to ensure that the carbon, silicon, manganese, phosphorus, and sulfur content in the steel meets SAE standards. If it does not meet the SAE standards, the steel material needs to be optimized. Then, the steel is placed in a separator, divided into spherical shapes and cooled in a water tank. The cooled steel balls are dried in a dryer, and the quenched scrap steel is crushed in a crusher to obtain semi-finished steel sand products. The semi-finished steel sand products are screened and classified to obtain finished steel sand products. At this time, the steel sand also needs to undergo secondary tempering to make the hardness of the steel sand moderate.

　　Characteristics of Blue Ground Steel Sand:

　　1. Moderate hardness:; Customized series: customized according to requirements;

　　2. Sharp edges: high cleaning efficiency;

　　3. Uniform particle size: effectively ensuring the uniformity of the workpiece surface;

　　4. Precision machining: Blue ground steel sand is all precision machined steel sand, with low consumption and fast cleaning speed, which can greatly shorten the time for surface treatment of workpieces.

　　The appearance is angular and made of broken steel balls. It is a commonly used material for metal surface processing, mainly used in air powered sandblasting machines. Steel sand has sharp edges, moderate hardness, and uniform particle size, which can effectively remove the oxide scale on the surface of metal workpieces, produce suitable roughness on the workpiece surface, and facilitate the adhesion and bonding of subsequent paint films. Due to the special modulation heat treatment of blue steel grit, it has low consumption and fast cleaning speed, which can greatly shorten the surface treatment time of workpieces. It is a very good surface treatment material. In short, Blue Earth Steel Sand is efficient and wear-resistant, reducing your overall costs while meeting your usage needs.
