根据用户需要,我厂承接了大批量、多品种的轻纺机械零件(包括自行车易损件脚踏轴、弹碗、纺机易损件导纱钩、盘等)热处理任务。这类零件过去多采用液体氰化(或渗碳)或气体渗碳,存在着污染环境、工效低或质量不易控制等缺点。我们做了在井式气体渗碳炉中进行气体碳氮共渗试生产,取得较好效果,正式在生产中应用。1.共渗设备和挂具我们将60和90kW 井式气体渗碳炉改装 According to user needs, I plant to undertake large quantities, more varieties of textile machinery parts (including bicycle wearing parts pedals, shells, textile machinery wearing parts yarn guide hooks, plates, etc.) heat treatment tasks. Such parts in the past more liquid cyanide (or carburizing) or gas carburizing, there is the pollution of the environment, inefficient or difficult to control the quality and other shortcomings. We have done gas carbonitriding trial production in well-type gas carburizing furnace and achieved good results, which are formally applied in production. 1. Percolation equipment and hanger We will 60 and 90kW pit gas carburizing furnace modification
