Product Details
Chemical elements : C ,Si ,Mn, p, s content% 0.65-1.10, 0.8-1.65, 1.20-2.0. < 0.05 hardness, microstructure of grinding balls HRC:50-65 (tempering) HRC:40-50 (tempering): the microstructure of the grinding balls of tempered martensite, tempering flexion bainite grinding pills than cast steel pill superiority embodied in the following aspects: 1. Grinding shot composition and stability. 2 grinding pill toughness and high tensile strength. 3 grinding pill to overcome all the weaknesses of the cast steel shot, no pores, not broken. 4 long service life. Grinding balls of steel balls with the consumption ratio: iron casting (sand) large, > 1000kg medium, is about 100kg small, < 10kg cast steel pill consumption quantity 2-4kg/ tons 6-8, kg / 8-10 tons, kg / tons of grinding steel shot consumption volume 1-2, kg / 3-5 tons, kg / 4-6 tons, kg / t use grinding shot benefits: 1. After cleaning workpiece surface colour is silvery white. 2 less environmental pollution. 3 the labor intensity of workers is reduced. 4 high efficiency, low consumption of pellets, reduce production costs.
