在我国,热处理工序的节能问题日益受到人们的重视和关注。许多冶金厂,特别是中小型钢铁厂,热处理设备相当陈旧,急需进行以提高生产效率和节能为中心的技术改造。为此,本文根据收集到的一些资料,结合几种新型的钢材热处理炉,对国外节能技术的现状作一简要介绍。 In our country, the issue of energy saving in heat treatment process has been paid more and more attention by people. Many metallurgical plants, especially small and medium-sized steel mills, and heat treatment equipment are rather obsolete and there is an urgent need to carry out technological transformations centered on improving production efficiency and saving energy. To this end, this article based on some of the information collected, combined with several new types of steel heat treatment furnace, the status of foreign energy-saving technologies for a brief introduction.
