The energy consumption of the third steelmaking plant of Handan Iron and Steel Group ranks among the advanced level in the industry

The three steelmaking plants of Handan Iron and Steel Company have always firmly grasped the center of maximizing efficiency, continuously increased efforts in energy conservation and consumption reduction, and strengthened energy awareness. In May, the converter’s gas recovery completed 118 cubic meters of steel per ton, and the amount of waste heat steam from the converter remained above 40 kilograms per tonne of steel. The integrated electricity consumption was 61.61 kilowatt-hours per ton of steel, which was 1.12 kilowatt hours less than the best record of history. The total energy consumption of the whole process has completed 12.54 kilograms of standard coal per ton of steel, reducing the standard coal by 3.54 kilograms compared with the goal of striving, and it has become a domestic advanced level in the same industry.

Negative energy steelmaking means that the total energy consumed in the steelmaking process is less than the total energy recovered. Gases and steam, which were once discharged in a vacuum, have now become a source of enormous wealth for energy generation. The realization of negative energy steelmaking is attributed to the optimization of new steelmaking companies. Process, improve energy and recycling. It is reported that in March 2011, the steelmaking plant of the three steel plants recovered 119.72 cubic meters of gas per ton converter, and the process energy consumption was -12.06 kilograms of standard coal.
