在迎接新的一年到来之际,预示一下机械行业热处理技术发展动向是很有意义的。机械制造工业中的热处理,是保证机械产品质量的一个重要环节。其任务也是十分艰巨的,突出的问题是提高产品质量和节省能源。当前,有以下一些问题值得我们认真考虑。 1.推广无氧化加热无氧化加热既可以提高热处理件的表面质量,又可以节省金属材料,减少机械加工工作量。国内现有可控气氛热处理炉的数量已不少,技术基本掌握,应当要求各厂充分发挥现有可控气氛炉的作用,力争尽早正常开动。同时还要注意改造、添置可控气氛炉。控制气氛类型,除吸热式及放热式气氛外,还应当推广氮基气氛及滴注气氛。不少单位在氮基气氛研究中,取得了一定成果,应该
In the face of the arrival of the new year, it is very significant to foreshadow the development trend of the heat treatment technology in the machinery industry. Heat treatment in the machinery manufacturing industry is an important part of ensuring the quality of mechanical products. Its mission is also very arduous, the outstanding problem is to improve product quality and save energy. At present, the following issues deserve our serious consideration. 1. Promotion of non-oxidation heating Non-oxidation heating can improve the surface quality of heat treatment parts, but also can save metal materials and reduce the workload of machining. At present, the number of controlled atmosphere heat treatment furnaces in China is quite large and the technology is basically mastered. All the factories should be required to give full play to the role of the existing controlled atmosphere furnace and strive to start the normal operation as early as possible. At the same time also pay attention to transformation, access controllable atmosphere furnace. Control the type of atmosphere, in addition to endothermic and exothermic atmosphere, but also should promote the nitrogen-based atmosphere and drip the atmosphere. A lot of units in the nitrogen-based atmosphere research, has achieved some results, it should be
