Anshan Iron and Steel Group's key project to build a quality raw material base - Anshan Iron and Steel Dagushan pellet production line was soon completed and put into production. This project, which produces 2 million tons of high-quality acid-oxidized pellets annually, will help Anshan Iron and Steel Mining Co., Ltd. achieve a transformation from traditional resource development and production to deep processing of mineral products and high value-added, high-tech mining enterprises.
As a high-quality man-made rich ore with iron ore as the main raw material, pelletized ore is a high-end product of metallurgical and mining enterprises. It is known as the “shunqi pill†of blast furnaces and has become an important raw material for modern steel enterprises. . In recent years, the Anshan Iron and Steel Mine System has overcome the difficulties in the processing of poor hematite ore dressing, completed the modernization of the old plant, and greatly improved the quality of iron ore concentrates. At the same time, since the "10th Five-Year Plan", Anshan Iron and Steel has vigorously eliminated backward production capacity, developed a recycling economy, took a new road to industrialization, and successively demolished small blast furnaces and flat furnaces. In order to meet the new requirements of new large-scale, modern blast furnaces for the variety, structure, and quality of iron-smelting raw materials, Angang decided to build two production lines with an annual output of 2 million tons of pellets in the Anshan Mining Company to achieve the most international construction. The goals of competitive steel companies provide quality raw material protection.
In the production line design, strict adherence to the principle of "high starting point, low input, rapid output, and high efficiency" and the goal of building a cost-effective, resource-saving, environment-friendly, and green ecological enterprise are fully absorbed. Based on the advanced experience at home and abroad, integrated innovation, has completed more than 30 technical research. The layout of the process adopts parallel arrangement and sharing of a set of public and auxiliary facilities, which reduces the large amount of land and investment. For the first time in domestic metallurgical mines, a tubular curve tape machine was used for material delivery to reduce secondary dust during material transportation and save land. The use of new, high-efficiency filtration equipment has transformed the plant, eliminating the drying process in pellet production and reducing energy consumption and pollution. The gas circulation system adopts advanced technological processes at home and abroad to recycle gas waste heat. Using PLC centralized control to achieve accurate ingredients, digital management, improve production efficiency. Through the optimization of design, the major indicators of process equipment and products have reached the international advanced level.
