我厂生产的连体飞轮芯子和平档是连体型的,这种飞轮是参考某名牌飞轮设计的。它具有结构合理、美观、省工省料(比普通飞轮每只省料0.27kg)等特点。但芯子的热处理是个难题。原因是按国标GB3576-83规定,芯子部分仅要求平档进行表面渗碳处理,而芯子的内外螺纹部分不允许处理。从有关资料介绍和光谱分析得知,某名牌飞轮的芯子部分是采用16Mn钢表面渗氮处理的;而我们的连体飞轮芯子是用B2-F普通钢制造的。在大批量生产情况下,用B2-F钢进行低温渗氮,很难达到有关技术指标。而其它化学热处理方法,又往往温度高、变
I plant the production of Siamese flywheel core peace file is Siamese-type, this flywheel is a reference to a brand-name flywheel design. It has a reasonable structure, beautiful, provincial labor saving (than the ordinary flywheel only save 0.27kg) and other characteristics. But the core heat treatment is a problem. The reason is that according to the national standard GB3576-83 stipulation, the core part only requires the flat file to carry on the surface carburizing treatment, and the inner and outer thread part of the core are not allowed to deal with. From the introduction of information and spectral analysis that the core part of a brand-name flywheel is nitriding 16Mn steel surface; and our Siamese flywheel core is made of B2-F ordinary steel. In the case of mass production, B2-F steel for low temperature nitriding, it is difficult to achieve the relevant technical indicators. Other chemical heat treatment methods, often high temperature, variable
