Abstract:Guixi Smelter has always been committed to the development of green smelting. Under the low energy consumption smelting level, it has created a new level of ecological and environmental protection, and a number of environmental protection indicators are in the international leading level. However, there are a series of problems such as high energy consumption and low resource utilization rate, low level flue gas emission and furnace body safety in the current long-term production process of depleted electric furnace, which run counter to the development concept of metallurgical. And not only the cost space is limited, but also the safety and environmental protection situation is difficult to control. In order to solve the current adverse situation, we must adhere to the "technology innovation leading" as the guide, build a highly efficient and coordinated operation control mode, aiming at the optimization and transformation of the direct discharge and slow cooling of the flash furnace slag of No.1 system of MCC, and constantly deepen the connotation of development to break out of the situation.
