低碳白口磨球广泛应用于电力、水泥及其它一些行业,需求量很大,现就φ60磨球的生产工艺作一介绍。 一、低碳白口磨球的材质特性 低碳白口磨球属亚共晶白口铸铁,其化学成份为(％):C1.9～2.4,Si0.3～0.8,Mn0.5～1.0,S<0.1,P<0.1,Re0.05。机械性能为:抗拉强度σ_b30～40kg/mm~2;抗弯强度σ_bb≥50kg/mm~2;冲击值α_k≥0.35kgm/cm~2;硬度HRC≥30～40。
Low-carbon white ball grinding ball is widely used in electric power, cement and other industries, the demand is great, is the production process of φ60 ball made an introduction. First, the material characteristics of low-carbon white ball mill Low-carbon white mill ball is sub-eutectic white cast iron, its chemical composition (%): C1.9 ~ 2.4, Si0.3 ~ 0.8, Mn0.5 ~ 1.0 , S <0.1, P <0.1, Re0.05. Mechanical properties: tensile strength σ_b30 ~ 40kg / mm ~ 2; flexural strength σ_bb ≥ 50kg / mm ~ 2; impact value α_k ≥ 0.35kgm / cm ~ 2; hardness HRC ≥ 30 ~
