在热处理工程师中间流行着一种看法:即在真空炉中的热处理方法,严格地说还处于实验室阶段。作者想强调下述情况:甚至在早期,当时的真空炉在操作上和许多情况中,相当肯定地能得到显著的工艺上和经济上的好处。这些好处不仅由于最终产品的清洁,高质量和可靠性,而且还由于能够减少或者省掉其它的加工过程,如热处理后的精整操作。在本文中,将提到各种各样的真空炉,虽然不可能在有限的篇幅中讨论设计和有关
There is a popular view among heat treatment engineers that the heat treatment in a vacuum furnace is strictly speaking in the laboratory. The author wishes to emphasize the fact that even in the early days the vacuum furnace at that time was fairly surely able to achieve significant technical and economic benefits both in operation and in many cases. These benefits are due not only to the cleanliness, high quality and reliability of the final product, but also to the reduction or elimination of other processing operations, such as post-heat treatment finishing operations. In this article, a variety of vacuum furnaces will be mentioned, although it is not possible to discuss the design and the related aspects in a limited space
