轴承行业先进热处理生产线的应用 Application of advanced heat treatment line for bearing industry 由于网带炉热处理生产线存在着产品磕碰伤、网带使用寿命相对较短等问题，国内知名企业如洛阳轴承集团、瓦房店轴承集团等采用了辊棒式可控气氛热处理生产线。针对较大轴承套圈油淬火容易产生托氏体，心部硬度难以满足客户需求问题，国内知名企业天马轴承、人本轴承等采用了硝盐代替油作为淬火介质，有效地解决了此问题。 Because the mesh belt furnace heat treatment production line there is a knock against injury, mesh belt service life is opposite shorter, domestic well-known enterprises such as luoyang bearing group, wafangdian bearing group adopted roller type controlled atmosphere heat treatment production line. For larger bearing ring oil quenching prone to austenite, the core hardness is difficult to meet customer demand, the domestic well-known enterprise tianma bearing, humanism bearing adopted nitrate instead of oil as a quenching medium, such as effectively solves this problem.
