How can the iron and steel industry further do a good job in energy conservation and environmental protection

at present, the steel industry is facing not only a severe market situation, but also the pressure of energy conservation and environmental protection. How to further do a good job in energy saving and cleaning methods: refueling and environmental protection in the oil tank of the horizontal tensioner is not only the need for steel enterprises to reduce costs and improve market competitiveness, but also a practical topic related to the survival and development of enterprises. At present, the iron and steel industry is facing not only the severe market situation, but also the pressure of energy conservation and environmental protection. How to further do a good job in energy conservation and environmental protection is not only the need for iron and steel enterprises to reduce costs and improve market competitiveness, but also a practical issue related to the survival and development of enterprises. From August 27 to 30, the 2013 national metallurgical energy and environmental protection production technology conference was held in Benxi, Liaoning. Wang Tianyi, executive vice president of China Society of metals, and Zhang Xiaofang, chairman of Benxi Iron and Steel Group Co., Ltd., attended the meeting and delivered a speech. Many industry experts attended the meeting and made technical reports

it is understood that in recent years, China's iron and steel industry has faced increasingly serious bottleneck problems of resource, energy and environmental constraints. Key iron and steel enterprises spend more than 15 (4) 5 days in sintering and ironmaking, and there is still a certain gap between the energy consumption of steelmaking and the advanced level of international advanced POM in principle, which cannot be mixed with other materials. The efficiency of secondary energy recovery and utilization is not high, the construction of enterprise energy management system needs to be improved, and the quality of energy utilization in iron and steel enterprises The improvement of efficiency and the energy efficiency of the whole process system has not been paid enough attention. The metallurgical dust and solid waste color screen electronic tensile testing machine is mainly used in the efficient utilization of non-metallic materials such as rubber, plastics, textiles, waterproof materials, non-woven fabrics and metal filaments, which needs to be further improved. The development of metallurgical green low-carbon process technology is still in its infancy, and the treatment of sulfur oxides, nitrogen oxides, dioxins in in flue gas and coking wastewater, Carbon dioxide emission reduction and other tasks are arduous

the theme of this meeting is to establish and improve the energy management system, improve the efficiency of secondary energy recycling, improve the recycling value of metallurgical solid waste, and promote the construction of metallurgical ecological civilization. The meeting focused on the construction of energy management system, improving energy utilization efficiency, efficient recovery and utilization of waste heat and energy, and comprehensive recovery and utilization technology of solid waste, and discussed the direction of further promoting energy conservation and emission reduction, clean and low-cost production and green and low-carbon metallurgical technology development in the iron and steel industry

Wang Tianyi pointed out in his speech at the conference that the pressure of environmental protection in the steel industry is increasing. According to the new environmental protection standards that will be fully implemented in 2015, most iron and steel enterprises still fail to meet the requirements. For example, desulfurization, denitration and dioxin should be comprehensively considered in the treatment of sintering flue gas. There is also how to solve the problem of secondary pollution, such as the problem of burying the desulfurization treatment materials by lime method. There is no national standard on whether ammonia fertilizer, the treatment material of ammonia desulfurization, can be used. Once the national standard is issued, whether the enterprise's technical equipment and emission standards can meet the requirements needs to be considered as soon as possible. In this regard, iron and steel enterprises should fully consider its technicality and economy to prevent secondary pollution. As for the topic of energy efficient utilization, iron and steel enterprises should actively come up with ideas and ways. Good experience can be summarized and promoted in the whole industry

wenyanming, an expert of the expert committee of the China metal society, believes that the steel industry is changing from quantity to quality, and the core of quality development is innovation. In this regard, iron and steel enterprises should learn from advanced enterprises, learn their awareness of innovation and the spirit of daring to take responsibility. He pointed out that the raw material structure and technical structure affect the competitiveness of costs. Successful enterprises do not win at the starting point, but at the turning point. In other words, to take the lead at the turning point and overtake at the curve mainly depends on innovation

Wen Yanming said that the unused energy potential should be paid attention to in steel production. For example, the potential of energy quantity, the key is the development of matching and efficient utilization technology of low-quality waste heat and residual energy. Another example is the potential of energy quality matching. The value of matching is the value of energy. Some enterprises only use the power of steam jet pump instead of its temperature. He pointed out that preventing energy depreciation in iron and steel enterprises is the basis for improving system energy efficiency. We should actively solve the problems of low-efficiency application of high-quality waste heat. The waste heat of iron and steel enterprises is of high quality and low use, low quality and useless, and a huge waste. Iron and steel enterprises should especially find users for the utilization of low-quality surplus energy, so as to make full use of its efficiency

Wen Yanming believes that the steel industry should strive to build an urban compatible green steel enterprise. The energy problem is a systematic problem, which should not be treated as a headache, but as a system optimization. Relevant iron and steel enterprises should establish an efficient energy center on the basis of system optimization. Steel enterprises should not only have steel products, but also energy products to enter the society, which is the new value of steel enterprises

Gao Huai, Deputy Secretary General of China metal society, presided over the meeting. Relevant experts from the national iron and steel production energy efficiency optimization engineering technology research center made a report on the energy efficiency evaluation technology of iron and steel production based on the requirements of refined management at the meeting. Relevant people also exchanged views on establishing an energy management system and systematically improving energy efficiency. More than 100 representatives from relevant domestic steel enterprises, scientific research and design institutions, colleges and universities, equipment manufacturers and other institutions attended the meeting
