Quickly understand low shell steel shot in one minute
1. Low shell steel shot is an upgraded substitute for ordinary cast steel shot. Common to all series.
2. Low shell steel shot is a patented product of Daya Metal, which is specially smelted and produced in an electric arc furnace (the only one in China).
3. Among the current users of steel shot, whether they are central enterprises, foreign companies, or private companies with standardized management, especially leading companies in various industries, 2/3 have chosen to use low shell steel shot as shot blasting material. . For example: automobile casting industry: GM, Toyota, FAW, Dongfeng, Chery, Great Wall, Tekesi; shipbuilding industry: CSSC, CSSC, COSCO Kawasaki, New Yangzi, New Era, etc.; steel industry: Shagang, Xiangtan Iron and Steel, Anshan Iron and Steel, Pohang Stainless Steel, Xingcheng Special Steel, etc.;
4. The outstanding advantages of low-shell steel shots: they are not broken and have twice the life span of ordinary steel shots, saving you 50% of shot blasting costs. .
Why not break? Because 1) the material is high-quality low-carbon alloy steel (carbon content is only 0.1-0.2%, contains a variety of alloy elements, and the alloy content is higher) 2) the metallographic structure is a more impact-resistant martensite and bainite composite type organize.
Is it hard enough? Will it be impossible to clean? During the smelting process, a variety of alloy elements are added, and after special heat treatment, patented technology is combined with automated assembly line production. The hardness ensures HRC42-48 (national standard 40-50), and the hardness is high enough to ensure its shot blasting efficiency.
5. Low shell steel shot is more environmentally friendly. Because it is not broken, the amount of steel shot is halved, which reduces the wear on the impeller, blades, guard plates, etc., so the dust is halved, reducing the load of the dust removal system, and the dust removal The consumption of spare parts such as cloth bags is reduced by half, creating good economic and social benefits.
