摘　　要：近年来,我国钢铁行业迅猛发展,钢产量逐年升高。冶金行业中各工序产生的低品位余热量都很大,余热利用率普遍较低。而热泵技术又是节能减排的重要新兴技术之一,如果能够利用钢铁行业的工业余热结合热泵技术,进行废热利用,不仅可以变废为宝,降低冶金行业的能耗,又可以减少对环境的热排放,符合目前国家提出的节能减排与绿色发展的战略方针。In recent years,the rapid development of China＇s steel industry make the steel production increased year by year. A lot of low-grade heat generated in the process of Metallurgical industry,and the residual heat utilization ratio is very low. The heat pump technology is one of the important emerging technologies of energy-saving emission reduction. Therefore,if companies can take advantage of the industrial waste heat and heat pump technology,using the waste heat,not only can make the waste into treasure,reduce the energy consumption of the metallurgical industry,but also reduce the heat emissions to environment. It is coincidence with the current national energy-saving emission reduction and green development of the strategic approach.
