本文利用系统节能的概念,研究了全行业系统节能中的主要问题——铁系统要取消土焦炼铁,钢系统要消灭二次化铁炼钢,材系统要基本实现一火成材。文中指出,不需要什么尖端技术和先进设备,主要靠行业的归口管理和组织协调,就能挖掘出约1300万t标煤的节能潜力。 In this paper, the concept of system energy-saving was used to study the main problems of system-wide energy saving in the whole industry-iron system should cancel the soil coke iron, the steel system should eliminate the iron ore secondary refining, the material system should basically achieve a firewood. The article pointed out that do not need any cutting-edge technology and advanced equipment, mainly by the centralized management and coordination of the industry, we can tap out about 13 million tons of standard coal energy saving potential.
