本钢采用EBT电炉→精炼(LF+VD)→中方坯连铸→连轧工艺生产轴承钢GCr15,其化学成分和检验结果全部达到本钢制定标准要求。其中As、Sn、Sb和Pb等残余元素远比标准要求低,另外[Ti]≤30×10-6,[Ca]≤8×10-6,[O]≤8×10-6,[H]≤0.8×10-6,轧材低倍、夹杂物、碳化物和脱碳检验指标也均达到标准要求,并优于GB/T18254-2002标准要求,满足瑞典SKF标准的要求。
Benxi Iron and Steel (Group) Co., Ltd. adopted EBT electric furnace → refining (LF + VD) → billets continuous casting → continuous rolling process to produce bearing steel GCr15. The chemical composition and test results all met the requirements set by Benxi Iron and Steel. Among them, the residual elements such as As, Sn, Sb and Pb are far lower than the standard ones. In addition, [Ti] ≤30 × 10-6, [Ca] ≤8 × 10-6, [O] ≤8 × 10-6, [H ] ≤0.8 × 10-6, rolling mill times, inclusions, carbides and decarburization test indicators have also reached the standard requirements, and better than GB / T18254-2002 standard requirements to meet the Swedish SKF standards.
