一、前言钢球等小零件在常规渗碳过程中会遇到一些难以解决的问题,如堆积起来渗碳不均匀,表面相互接触造成局部软点现象等。为了解决这些问题,我们经过五年的实践,研制出回转式真空渗碳炉成功地用于钢球生产,既提高产品质量,还减少渗碳时间,节省费用,受到用户的好评。 First, the foreword Ball and other small parts in the conventional carburizing process will encounter some unsolved problems, such as accumulation of uneven carburization, the surface contact with each other caused by local soft spots and so on. In order to solve these problems, after five years of practice, we developed a rotary vacuum carburizing furnace successfully used for steel ball production, which not only improves the product quality, but also reduces the carburizing time and saves the cost, which is praised by users.
