產(chǎn)品詳情
與全淬透的GCr15鋼軸承相比,GCr4鋼軸承的壽命明顯提高,可用于重載高速列車軸承。今后軸承鋼主要向高潔凈度和性能多樣化兩個(gè)方向發(fā)展。提高軸承鋼的潔凈度,特別是降低鋼中的氧含量,可以明顯延長(zhǎng)軸承的壽命。氧含量由28ppm降低到5ppm,疲勞壽命可以延長(zhǎng)1個(gè)數(shù)量級(jí)。為了延長(zhǎng)軸承鋼的壽命,人們多年來一直致力于開發(fā)應(yīng)用精煉技術(shù)來降低鋼中的氧含量。通過不懈的努力,軸承鋼中的氧含量已從2世紀(jì)6年代的28ppm降低到9年代的5ppm。

為了使工件表面和內(nèi)部都獲得滿意的力學(xué)性能,必須采用真空高壓氣淬技術(shù)。目前上真空氣淬的氣壓已從.2MP.6MPa提高到1~2MPa甚至3MPa。所以高壓氣淬真空爐的冷卻氣體壓力的逐步提高是一個(gè)重要的發(fā)展趨勢(shì)。除高壓氣淬外,在先抽真空而后填充高壓惰性氣體后施行對(duì)流加熱可以比傳統(tǒng)真空輻射加熱速度提高一倍以上,從而明顯提高加熱效率也是真空加熱技術(shù)的重要方向之一。向多功能發(fā)展也是真空爐的趨勢(shì)之一。
