我厂对于小件淬火原来采用RJX-30-9中温箱式电炉加热。为防止氧化脱碳采用装箱保护,但是工件表面仍有不同程度的氧化脱碳,淬火后零件质量差,而且生产效率低,劳动条件差。为解决上述问题,我们自行设计和制造了一台半自动推进式气体保护炉,经两年多的生产使用效果良好。现介绍如下,供大家参考。 I plant for small pieces of the original use of RJX-30-9 in the oven electric furnace heating. In order to prevent the oxidation decarburization packing protection, but the surface of the workpiece is still varying degrees of oxidation decarburization, after quenching the parts quality is poor, and the production efficiency is low, poor working conditions. In order to solve the above problems, we designed and manufactured a semi-automatic pusher gas protection furnace, which has been used well for more than two years. Now introduced as follows, for your reference.
