工业炉节能不是特别新的课题。在高温处理方面,如何节约燃料,以前就有过研究,并在不断努力。但是,研究象渗碳炉这样的热处理炉节能问题,从1973年石油冲击以来一直是个大课题。自那时起,重点是如何以少的投资来增加生产。即与节能措施的投资效果相比,要以提高生产能力为目的来提高投资效果。为了扭转由于石油冲击造成的燃料价格上涨的局面,主要的办法是节能。 Industrial furnace energy saving is not a new topic. In the field of high-temperature treatment, how to save fuel has been studied before and continuous efforts have been made. However, studying the issue of saving energy in heat-treating furnaces like carburizing furnaces has been a major issue since the oil shock of 1973. Since then, the emphasis has been on how to increase production with less investment. That is, compared with the investment effect of energy-saving measures, it is necessary to improve the investment effect with the purpose of improving production capacity. In order to reverse the fuel price hikes caused by the oil shock, the main solution is energy saving.
