【据《Trans.ISIJ 》VoL.27.№.2.198764页报导】日本Aichi钢厂已经能够大批量生产疲劳寿命可与ESR或VAR的产品相媲美的高碳滚珠轴承钢。众所周知,ESR产品中氧化夹杂物的分布比一般钢锭和连铸钢坯中的夹杂物分布更均匀。因此,这意味着Aichi钢厂通过应用一种新的LF-RH钢坯连铸法来减少氧化夹杂物,使其产品达到了ESR产品相同的效果。 According to Trans.ISIJ VoL.27.No.2.198764 Japan’s Aichi Steel has been able to mass produce high-carbon ball bearing steels with comparable fatigue life comparable to ESR or VAR products. It is well known that the distribution of oxidized inclusions in ESR products is more uniform than the inclusions in normal ingots and continuous cast billets. This means, therefore, that Aichi uses a new LF-RH billet continuous casting process to reduce oxidized inclusions and achieve the same result as the ESR product.
