The 12th Five-Year Steel Industry will focus on process optimization and secondary energy recovery, improve the quality of materials and fuels, increase the ratio of blast furnace coal injection to pellets, increase scrap recycling and comprehensive utilization, and reduce iron-to-steel ratio. Vigorously develop green steel products, effectively control the growth of steel production, eliminate sintering machines below 90 square meters, blast furnaces of 400 cubic meters and below, converters and electric furnaces of 30 tons and below, and the height of carbonization chambers is less than 4.3 meters (3.8 meters of tamping coke ovens) Machine coke oven, iron alloy electric furnace of 6300 kVA and below, iron alloy semi-closed DC electric furnace of 3000 kVA and refined electric furnace. We will increase the technological transformation of energy efficient recycling, conversion and utilization, and improve the comprehensive utilization of secondary energy. Fully promote coke oven dry quenching, converter gas dry dust removal, blast furnace gas dry dust removal, coal conditioning, continuous casting billet hot charging, converter negative energy steelmaking and other technologies; focus on the promotion of sintering pellets low temperature exhaust gas waste heat utilization, On-line heat treatment of steel; demonstration and promotion of waste heat recovery and utilization, dehumidification blast, use of coke oven to absorb waste plastics and waste tires; research and development of high-temperature steel slag iron slag sensible heat recovery technology, direct reduced iron production process, etc. Accelerate the application of power saving technology and energy-saving transformers for motor systems. By 2015, the proportions of technologies such as converter negative energy steelmaking, dehumidification blast, sintering waste heat power generation, and coal conditioning will reach 65%, 20%, 40% and 50% respectively. The main process energy consumption and energy utilization efficiency targets of the steel industry are as follows: Coking: By 2015, the number of enterprises whose energy consumption has reached the advanced value of the national unit product energy consumption limit standard accounted for 60%. Sintering: By 2015, the number of enterprises with energy consumption reaching the advanced value of the national unit product energy consumption limit standard accounted for 15%. Blast Furnace: By 2015, the number of enterprises whose energy consumption has reached the advanced value of the national unit product energy consumption limit standard accounted for 15%. Electric furnace: By 2015, the number of enterprises whose energy consumption has reached the advanced value of the national unit product energy consumption limit standard accounted for 65%. Comprehensive utilization of secondary energy: The utilization rate of residual heat and residual pressure of large and medium-sized iron and steel enterprises is more than 50%, and the proportion of self-generation by secondary energy of by-products is more than 50% of total electricity consumption.
