国际先进工业国家均采用电炉(转炉)-炉外精炼-大方坯连铸的工艺生产以轴承钢、齿轮钢等为主要产品的特殊钢。本钢炼钢厂采用LD-LF-RH-CC工艺路径成功地进行了GCr15钢生产试验试制。生产试验结果达到或接近SKF标准,试验过程中积累了经验同时也发现了不足,为今后批量生产此类钢种打下了坚实基础。
International advanced industrial countries are using electric furnace (converter) - furnace refining - bloom casting process to produce bearing steel, gear steel, etc. as the main product of special steel. Benxi Iron and Steel Mill LD-LF-RH-CC process successfully GCr15 steel production trial trial. Production test results at or near the SKF standard, the test process has accumulated experience and also found deficiencies for the future mass production of such steel laid a solid foundation.
