Abstract: The ordinary method of energy conservation and emission reduction has been out of time. Energy saving should focus on the reform of technology and equipment instead of facing the energy sources and pollutant only. According to the new situation and demands caused by changing stage of Chinese steel industry development, and through the study at home and abroad and the preliminary research, developed countries thought energy conservation and emission reduction depending on technology could not achieve better effect. We should reduce the production of energy consumption and pollutant from the source on the premise of ensuring the production and quality of products by way of technology revolution and innovation. On the basis of the reality that few industries achieved energy conservation and emission reduction through technology improvement, new technology and methods used to save energy and reduce emission in foreign metallurgy industries were analyzed and summarized. Basic ways of energy conservation and emission reduction for Chinese metallurgy industries is concluded, that is the research on new technology and new equipments of saving energy and reducing emission should be taken up, meanwhile, current research should continue and technology of energy conservation and emission reduction should be promoted. Some case studies on new technological equipment for energy conservation and emission reduction from the source in China was introduced.
