我厂生产的打火机的钢轮,其硬度及耐磨性一直不理想。曾选用优质钢材经盐浴直接加热、液体氰化、固体渗碳等热处理方法,均得不到良好质量。为进一步解放生产力,参考了上海、北京有关渗硼介绍,以及广东工学院的渗硼科研成果,结合我厂实际,选取了液体渗硼工艺,取得一些成果。液体渗硼的优点是: 1.使用原料(硼砂、碳化硅等)来源易,成本低。
The lighters produced by our factory have not been ideal for hardness and wear resistance. Had selected high-quality steel directly heated salt bath, liquid cyanide, solid carburizing and other heat treatment methods, are not good quality. In order to further liberate the productive forces, with reference to the introduction of boronizing in Shanghai and Beijing and the boronizing scientific research results of Guangdong Institute of Technology, the liquid boronizing process was selected according to the actual situation in our factory, and some achievements were made. The advantages of liquid boronizing are: 1. The use of raw materials (borax, silicon carbide, etc.) easy to source, low cost.
