The steel industry needs to accelerate the development of green

Date of release:2018-07-16 Author: Click:

In recent years, China's steel industry has made great achievements, but the environmental pressures facing it have gradually increased. As a resource- and energy-intensive industry, the development of the steel industry is accompanied by a large amount of energy consumption and pollutant emissions. The industry believes that the whole process of steel manufacturing, the whole life cycle of steel products, and the all-round development of green industry should be considered to promote the green development of the industry.

Under the background of the country's vigorous promotion of ecological civilization construction, the steel industry has entered the stage of reduction and development. Green development has become the main direction of steel future development, and it is also the key to the transformation and upgrading of the industry. Recently, the “Steel Industry Green Manufacturing Technology Experience Exchange Meeting” hosted by the Metallurgical Industry Planning and Research Institute was held in Handan City, Hebei Province. The industry gathered together to provide suggestions for the steel industry to promote green development.

Environmental pressure is gradually increasing

In recent years, China's steel industry has made great achievements, but the environmental pressures facing it have gradually increased. In 2017, ferrous metal smelting and rolling energy consumption accounted for 16.3% of the country's total energy consumption, and sulfur dioxide, nitrogen oxides, and dust emissions accounted for 19.7%, 12.0%, and 27.6% of key industries, respectively.

“The energy consumption of the steel industry is huge, and the dependence of iron ore is high, which has produced a large amount of industrial solid waste, which has brought great pressure on resources, energy and the ecological environment.” Gao Yunhu, Director of the Department of Energy Conservation and Comprehensive Utilization of the Ministry of Industry and Information Technology Point out.

A number of industry experts said that accelerating the green development of the steel industry is a requirement for the construction of ecological civilization and a key task for the high-quality development of the industrial economy in the new era. Gao Yunhu believes that promoting the green development of the steel industry can focus on three aspects. First, further accelerate the green transformation, promote the application of advanced green manufacturing technology, and improve the energy and energy utilization and clean production level of the industry. The second is to give full play to the benchmarking role of the industry's green factories, strengthen technical exchanges, encourage steel companies to promote the coupling development with the building materials, electricity, chemicals and other industries and cities, and promote the overall green improvement of the industry. The third is to speed up the standardization and revision of energy consumption, water consumption, clean production, encourage the establishment of corporate standards that are stricter than national standards, and improve the standardization of green development in the steel industry.

Key enterprises actively

Representatives from more than 60 steel companies, technology companies and scientific research institutions from China Baowu, Hegang, Shougang, Taigang, Angang, Xinxing Casting, Liugang, Linggang, Delong Iron and Steel, Tiangang and others participated in this Meeting. It can be seen from the introduction and exchange of the participating enterprises that a large number of key steel and steel enterprises attach great importance to green development and solidly promote related work.

 During the meeting, the delegates visited the CSCR desulfurization and denitration process of Hegang Steel Sintering Machine and the ironmaking plant, cold rolling mill and fully enclosed mechanized raw material field, and fully affirmed their efforts in energy saving, environmental protection and upgrading. . In recent years, Hegang Steel has firmly established and practiced the concept of “Green Water Qingshan is Jinshan Yinshan”, rooted the green development concept in all aspects of enterprise production and management, and has invested RMB 13.8 billion to implement 115 environmental protection and energy conservation projects. The main pollutants have achieved ultra-low emissions in an all-round way and have been identified as “green factories” by the Ministry of Industry and Information Technology.

Today, the greening area of the Hegang Steel Plant has exceeded 55%, achieving “the mine is not mine, the coal is not seen, the materials are not seen, and the iron is not seen”. Green transformation has promoted the high quality of the company. In the first five months of this year, the proportion of steel products of this enterprise exceeded 85%, which was 5.8 percentage points higher than last year; the proportion of medium and high-end was 80.3%, up 18.3 percentage points over last year; 46 new products were developed, and the benefits were quickly improved in green development. . Guo Jingrui, chairman of Hegang Steel Co., Ltd., said that Hegang Steel will fully promote the production of clean, green and high-end products, and strive to become a green steel demonstration enterprise with good efficiency, high efficiency, low consumption, low emissions and beautiful environment.

As the world's largest stainless steel enterprise, TISCO has built a “1124” green development model in practice, which is to establish a concept – steel mills and cities are “communities” of harmonious development; establish a goal – to build energy saving in the metallurgical industry Recycling circular economy demonstration factory; relying on "two innovations" technology innovation and management innovation; expanding "four major functions" product manufacturing, energy conversion, waste disposal treatment, greening and beautification, the main energy consumption and environmental protection indicators have reached the advanced level in the industry, Out of a new path of the development of a large steel mill and the modern city.

"We always regard green development as the premise of survival, the foundation of development, new growth points and competitiveness." The relevant person in charge of Taigang said that the company invested 13.6 billion yuan in 10 years and implemented 147 projects to build a complete solid state. Liquid and gaseous circular economy industrial chain.

Not only steel state-owned enterprises take responsibility, but also private enterprises. “Environmental investment does not cost, there is no cap.” Delong Steel’s responsible person revealed at the meeting that since 2014, Delong Steel has invested 1.28 billion yuan to carry out in-depth management and upgrading of more than 100 environmental protection projects. The environmental protection operation cost per ton of steel reaches about 200 yuan.

The industry still needs to work harder

Although many steel companies have made significant progress in energy conservation and environmental protection, overall, the green development of China's steel industry is still in its infancy, and there is still a lot of work to be done to truly achieve green steel companies.

Zhao Chunli, deputy researcher of the Department of Atmospheric Environment Management of the Ministry of Ecology and Environment, pointed out that the green development of the steel industry and enterprises should not only pay attention to the end management, but also focus on reducing the generation of pollutants from the source. Source reduction depends on technological innovation. Many steel companies still have the potential to dig in sintering pellets, reducing emissions from flue gas cycles and recovering waste heat.

Li Xinchuang, president of the Metallurgical Industry Planning and Research Institute, proposed that the steel industry should gradually establish a theoretical system, evaluation system and method system for the green development of steel processes, and establish a mature green development system to regulate the green development of steel enterprises. Improve the green development level of the industry. Specifically, from the perspective of the whole process of steel manufacturing, the whole life cycle of steel products, and the all-round development of green industry, the implementation of the six-in-one of “green mines, green procurement, green logistics, green manufacturing, green products, and green industries” should be implemented. layout.

“Green transformation is the inherent requirement of enterprise development.” Li Xinchuang called on iron and steel enterprises to establish green development strategic thinking, actively innovate, consolidate green development capacity building, strengthen the construction of professional talents, learn to understand outstanding enterprises, advanced technologies, and accelerate implementation. Effective and effective green development actions.
