At the 2018 (ninth) China Steel Energy Conservation and Emission Reduction Forum held recently, Li Xinchuang, president of the Metallurgical Industry Planning and Research Institute, said that the environmental protection work of the steel industry has made positive progress. In the past 10 years, tons of steel such as sulfur dioxide and particulate matter have been discharged. The amount of decline is more than 60%. Due to the large steel output, the sulfur dioxide, nitrogen oxides and particulate matter emissions in the steel industry rank third, third and first respectively in all industrial sectors, and remain the main battlefield for the blue sky defense war.

Li Xinchuang said that the environmental protection level of iron and steel enterprises is very different. There are enterprises such as Baosteel and Taigang that have reached the world's advanced level, and there are also a number of backward enterprises with serious pollution. The prevention and control of air pollution in the steel industry has just entered the deep water area: the industrial structure and industrial layout need to be adjusted; the process and energy structure need to be optimized; the level of environmental protection equipment needs to be upgraded.

According to the "Work Plan for Ultra-low Emissions Transformation of Iron and Steel Enterprises (Draft for Comment)", the corresponding control standard requirements are: sintering head flue gas, pellet roasting flue gas under the condition of 16% of reference oxygen content, particulate matter, sulfur dioxide, nitrogen The hourly average emission concentration of oxides is not higher than 10 mg/m3, 35 mg/m3, and 50 mg/m3 respectively; the hourly average emission concentrations of particulate matter, sulfur dioxide and nitrogen oxides of other pollution sources are not higher than 10 mg/m3 respectively. 50 mg/m3, 150 mg/m3.

Li Xinchuang said that the introduction of ultra-low emission standards in the steel industry marks the beginning of the nationwide atmospheric governance work in the non-electrical industry. The most stringent emission standards in this history show the government's determination to resolutely control air pollution and win the battle against blue sky; environmental protection tax, differentiated electricity price, and “differential production limit” and other multi-dimensional reward and punishment policies for ultra-low emission transformation. Execution and continuity provide a strong guarantee.
