Abstract TISCO, which is an integrated iron and steel enterprise in China, have the largest capacity of stainless steel with the most advanced technology and equipment in global. Since 2005, particularly in the system renovation of the new stainless steel, relevant energy saving and emission reduction projects were built. In the construction, the most advanced technology was adopted and the technology of the whole process of mining, coking, iron making, steel making and rolling was updated, realizing updating of main technical equipment. At present, Tisco has formed an annual output capacity of 10 million tons of steel, including 3 million tons of stainless steel. Through analysis of the whole energy-saving direction of iron and steel industry combined with the condition of energy saving in TISCO in recent years, specific measures were implemented from the process to technical aspects of energy management, energy conservation around a variety of waste heat and energy utilization, blast furnace slag utilization, the comprehensive utilization of steel slag and exhaust purification program, and remarkable results was achieved. Between 2005 and 2010, the comprehensive energy consumption per ton of steel had been dropped from 703kg/t to 559kg/t, decline up to 20.5％. Water consumption per ton of steel had been dropped from 7.18t/t to 1.91t/t , decline up to 73.3％. Finally, the direction and measures of the future energy saving work of TISCO is presented.
