目前,气体渗碳氮化工艺广泛地应用于自行车工业上,以提高自行车传动部件如轴消、轴腕、链条另件等的强韧性、耐磨性、耐腐蚀性及接触疲劳强度,提高自行车另件的使用寿命是势在必行。天津链条厂原有设备(盐炉等)不能满足工艺要求,为此从日本东方机械工程公司引进了 UM-5042网带式渗碳氮粑炉两台。实践证明,在该设备上进行自行车另件的渗碳氮化,可成倍的提高另件的
At present, the gas carburizing and nitriding process is widely used in the bicycle industry to improve the toughness, abrasion resistance, corrosion resistance and contact fatigue strength of bicycle transmission components such as shaft elimination, shaft wrist and chain parts, and to improve the bicycle Another piece of life is imperative. Tianjin Chain Factory original equipment (salt furnace, etc.) can not meet the process requirements, for this purpose from the Japanese Oriental Mechanical Engineering Company introduced UM-5042 mesh belt carburizing nitrogen furnace two. Practice has proved that in the device for carbonation nitriding of another piece can be multiplied to improve the other pieces
