远红外加热技术是节能的有力措施,具有实施简单,上马快,使用寿命长和维修方便等优点。它在低于600℃加热干燥方面的节能效果已有很多报导,人们希望在高于600℃的金属热处理工艺中能应用它,借以节约能耗。这几年,不少单位曾在这方面做了不少工作,有的取得一定效果,有的则根本收不到效果,对其前途和可行性争论较大。笔者认为,这是由于尚缺乏理想的涂料品种。因为对于一般的远红外涂料,在中高 Far-infrared heating technology is a powerful measure of energy saving, with the implementation of simple, quick start, long service life and easy maintenance. It has been reported that the energy saving effect of heating and drying at a temperature lower than 600 ° C has been reported. It is hoped that it can be applied to a metal heat treatment process above 600 ° C to save energy. In recent years, quite a number of units have done a great deal of work in this respect. Some have achieved some results, while others have not received any results at all and the debates over their future and feasibility are even greater. In my opinion, this is due to the lack of ideal coating varieties. Because for the general far-infrared coating, in the high
