大冶钢厂50t高功率电弧炉—60t VAD精炼生产的轴承钢可完全除去对轴承钢疲劳寿命危害最大的D类夹杂物,得到较低的B类夹杂评级和较低的氧含量,使轴承钢内在质量的主要指标达到世界先进水平。采用计算机对精炼过程进行控制可得到低而稳定的氧含量。
Daye Steel 50t high-power electric arc furnace -60t VAD refined production of bearing steel can completely remove the bearing steel, the most damaging fatigue life Class D inclusions, get a lower Class B inclusion rating and lower oxygen content, so that the bearing The main index of internal quality of steel has reached the world advanced level. Using a computer to control the refining process results in a low and stable oxygen content.
