轴承钢冶炼技术的发展是探索净化钢水、减少气体和非金属夹杂物含量的新技术,它的生产和科研包括冶炼方法、脱氧工艺、夹杂物、碳化物以及疲劳寿命的研究,是我国特殊钢生产中投入人力、物力、财力最多的钢种。我国特钢生产的特点是炉容小、模铸比例高、轧制及热处理工艺落后。经过“六五”、“七五”、“八五”“九五”的课题攻关,我国特殊钢生产技术进入了精炼的时代,氧含量从电弧炉大气熔炼下的30×10~(-6)
The development of bearing steel smelting technology is to explore the purification of molten steel, reducing gas and non-metallic inclusions in the new technology, its production and research, including smelting methods, deoxidation process, inclusions, carbides and fatigue life, is China’s special steel Production into manpower, material and financial resources of the largest steel. China’s special steel production is characterized by small furnace capacity, a high proportion of molding, rolling and heat treatment process behind. After the “Sixth Five-Year Plan”, “Seventh Five-Year Plan”, “Eighth Five-Year Plan” and “Nine Five-Year Plan” project, China’s special steel production technology has entered a refining era. Oxygen content is reduced from 30 × 10 -6 )
