Since the beginning of this year, the steelmaking operation area has anchored the goal of “reducing cost per ton of steel” and has actively explored and practiced energy conservation and consumption reduction, achieving remarkable results. From March to May, the electricity consumption per ton of steel in the converter area decreased by 17.8% compared with the same period last year, achieving energy savings of 242,000 yuan.
In order to reduce the electricity consumption per ton of steel, the operation area has implemented a series of effective innovative measures.
On the one hand, the “avoiding peak and valley” production mode is deeply implemented, and the dynamic adjustment of the converter operation strategy is achieved by establishing a real-time electricity price monitoring and production linkage mechanism.
During the peak period of daily electricity prices, one converter is retained to support continuous smelting operations to ensure the continuity of production, while another converter is arranged for low-energy operations such as equipment maintenance, effectively avoiding energy loss caused by frequent start-up and shutdown of high-energy-consuming equipment.
On the other hand, we will continue to optimize the production organization process, promote the “fast iron mixing and blowing” process of molten iron, and reduce the temperature consumption in the process by shortening the interval between iron mixing and blowing;
Vigorously promote the “steeling without falling furnace” technology, strengthen the skill training of furnace masters and rely on the carbon and temperature measurement of TSC in the smelting process to improve the smelting end point hit;
Try the molten steel treatment process directly from the converter to reduce the transfer time of the intermediate links, so as to improve the overall flow efficiency of molten steel from the converter to the continuous casting process, promote the significant reduction of the processing time within the production process and the waiting time between processes, and effectively control the energy consumption of the process.
