近几年来,应用中、高温远红外炉加热金属,在实验室和生产中做了大量工作。但从所发表的数据来看,差异很大。有些文章认为:应用远红外炉加热可节能20%～30%,有的甚至高达70%～80%。但也有不少文章认为:用中、高温远红外炉加热金属效果不显著。甚至认为:“用涂料或其他东西将电阻丝(或带)屏蔽起来是有害的。”本文将从基本实验事实出发,分析讨论中、高温远红外加热金属是否节能,并对节能机理进行初步探讨。
In recent years, applications, high temperature far-infrared furnace heating metal, a lot of work in the laboratory and production. However, according to published data, the difference is very large. Some articles believe that: the application of far-infrared heating furnace can save 20% to 30%, and some even up to 70% to 80%. But there are also many articles that: with medium and high temperature far-infrared heating furnace metal effect is not significant. Even thought: “The use of paint or other things will be shielded wire (or belt) is harmful.” This article will proceed from the basic experimental facts, analysis and discussion, the high-temperature far-infrared heating of metal is energy-saving, and preliminary study on energy-saving mechanism .
