一、概述节能涂料主要是将一种辐射率(黑度高ε)的材料涂到炉墙表面,从而提高炉墙内表面的黑度和温度,加强对被加热物的辐射,达到节能的目的。随着工业炉节能问题越来越被人们重视,炉墙黑度对传热的影响也随之提到议事日程。苏联“锻压生产”杂志在78年就发表过研究文章,主要注重于理论公式,但没有予以肯定的结论。79年以后,日本多种杂志作了节能涂料应用的报导,据资料介绍,炉温为1100℃的燃油连续加热炉可节油6％、周期式燃料加热炉可节约燃料10～17％,加热周期可短缩15％左右,并且认为节能涂料在电炉上也有效果。由于节能涂料费用低廉,涂料费可在1～3
First, an overview of energy-saving coatings is mainly a radiation rate (high black ε) of the material is applied to the furnace wall surface, thereby increasing the furnace wall surface blackness and temperature, to enhance the radiation on the heated object, to save energy . With the industrial furnace energy conservation issues more and more attention, the impact of furnace wall blackness on heat transfer also mentioned the agenda. The Soviet Union, “Forging Production” magazine published in 78 years of research articles, the main focus on the theoretical formula, but did not be conclusive. 79 years later, many magazines in Japan made reports on the application of energy-saving coatings. According to the introduction of the materials, a fuel continuous furnace with a furnace temperature of 1100 ° C can save 6% of fuel, a periodic fuel furnace can save 10-17% of fuel, Cycle can be shortened by about 15%, and that energy-saving coatings also have effect on the electric stove. Due to the low cost of energy-saving coatings, coating fees can be 1-3
