Prediction and potential analysis of green metallurgy innovation development situation

It is urgent for the non-ferrous metal industry to carry out in-depth industrial structure adjustment to achieve scientific layout, and should abandon extensive production increase in the future, and actively turn to the deep-processing of non-ferrous metals with higher added value and wider demand. ① Based on the industry background of sufficient production capacity, drive industrial transformation and upgrading with advanced technology, improve quality and efficiency, form a complete industrial chain, and accelerate the transformation and upgrading from low-end to high-end, high-speed development to high-quality development; Promote the non-ferrous metal industry and aviation, aerospace, automotive, equipment manufacturing and other industries, from traditional industrial applications to expand to new industrial applications. (2) Overall planning of resources, energy, environment, transportation and other production factors inside and outside the country (environment), overall optimization of the non-ferrous metal industry layout, promote the withdrawal of inefficient production capacity, encourage the existing production capacity to energy, resource enrichment areas, concentrated consumption areas transfer, such as electrolytic aluminum industry to the west transfer, aluminum processing industry to the north transfer; The formation of coal (water) - electricity - alumina - electrolytic aluminum - aluminum deep processing - recycled aluminum integration "efficient aluminum industry chain", as far as possible the primary aluminum local or nearby into deep processing products, parts manufacturing, semi-finished products, finished products, production services extended.

4. Promote the application of process information and realize industrial intelligent manufacturing

Intelligent manufacturing has become the development trend of many industries, and the introduction of metallurgical enterprises can not only improve productivity and product quality, but also achieve the interconnection of production information. In the future, the steel industry will make full use of the new generation of information technology to continuously improve the level of digitalization, networking and intelligence; Take intelligent manufacturing as the development theme [23] to promote transformation and upgrading and high-quality development. Specifically, a big data platform of process parameters - product comprehensive performance - quality stability is built, the process parameters of the whole process of product production are deeply optimized, and the intelligent process model database of product production is established which is suitable for mass customization and multi-process coordination. In the future, the non-ferrous metal industry will break through the traditional division of labor interface of non-ferrous, steel, chemical, construction and other industries, and form cross-industry composite enterprises or joint enterprises in the way of interest coordination, so as to achieve green, low-carbon and safe development while enhancing the high-end supply capacity of new non-ferrous metal materials.

(2) Innovation and development potential of iron and steel metallurgy

At present, China's steel industry to capacity remarkable results, from the source to ensure the level of green development of the industry, in the "13th Five-Year" period not only completed in advance of the target limit (1.5×108 t), but also banned a certain scale of "strip steel" capacity (1.4×108 t). In this process, the performance of process equipment is significantly improved, and the promotion of advanced green technology is accelerated; The capacity of 5.5m and above tamping, 6 m and above top charging coke oven increased by 6.7%, the capacity of 1000 m3 and above blast furnace increased by 6.5%, and the capacity of 100 t and above converter and electric furnace increased by 10 percentage points. In addition, the green development capacity has been significantly improved, energy conservation and emission reduction indicators have been significantly improved, such as the key statistics of the average ton of steel SO2, NOx, particulate matter emissions of iron and steel enterprises have decreased by 48%, 18%, 39%, and the comprehensive energy consumption of tons of steel has decreased from 0.572 tce to 0.554 tce.

In the face of the urgent need for higher levels of green development, the development of new green processes, equipment and technology, and the construction of green steel industry production mode that ADAPTS to the characteristics of national conditions. The use of industrial structure optimization, reasonably improve industrial concentration and broaden market influence, completely change the industry development of "small scattered" situation, with advantageous enterprises to drive the green development process of the whole industry. Promote the transformation of raw material structure and process flow, and strive to reach 30% of the national iron and steel industry scrap by the end of the "14th Five-Year Plan", and increase the proportion of electric furnace steel to 20%. Implement the green upgrading of steel and accelerate the high-value and concentrated development of the comprehensive utilization of resources industry; Encourage steel enterprises to build a comprehensive industrial base for waste resources that can play a leading role in the market, and effectively promote the coupling development of steel and building materials, electric power, chemical and other industries. We will improve the standard system for green manufacturing, and fully establish a standard system for energy saving, water saving, and comprehensive utilization of resources in the steel industry.
