    钢材的冶炼质量控制、轧制质量控制和后期的产品深加工同样重要。新万博苹果下载一在上海宝钢集团的生产现场,采用精炼+真空+连铸+钻孔法+表而扒皮的生产流程,严控质量要点包括但不仅限于:

    非金属夹杂物含量A、B、C、D≤0.5
    ·有害元素Pb、Sn、Sb、As等残留≤0. 01%
    气体含量O≤ 10ppm,H≤2ppm
    *轧制表面脱碳≤0.05mm

    Drill steel smelting qualiw control, ro) ling quality control and further products deep processing are equally important. HOPH use following mantJfacnJre process, Refining + Vacuum + Continuous casting + Driuing hole method +surface peeling at Shanghai Baosteel production site. Strictly quality control not only include
    above process, also control

    Non Metallic inclusion content A. B. C. D. S≤0. 5
    Harmful Rlement Residues Pb. Sn. Sb. As.etc. ≤ 0. 01%
    Gas Content 0 ≤ 10ppm, H ≤ 2ppm
    Rrouing Swface Decarburizatinn ≤ 0. 05mm
