The latest direct reduction electric furnace steelmaking short process equipment has been successfully developed

The specific feature of this equipment is to mix powder ore and coal in proportion to form pellets, which are dried and laid in equipment with continuous feeding, continuous preheating in a tubular furnace, continuous melting, and continuous smelting functions. The pellets are heated to 1250-1350 ℃ using powder coal (or gas) to achieve rapid production of metallized pellets. After unloading, they are directly hot charged and continuously added to the electric furnace for smelting to generate high-quality molten iron. This method has high efficiency and saves money, and it has become a leap in the development of steel metallurgy technology, once again reflecting the importance of new equipment innovation.
Direct reduction iron, as a substitute for scrap steel to supplement the shortcomings of scrap steel, has successfully developed a new type of direct reduction electric furnace steelmaking short process equipment. With the progress of industrial technology, users' requirements for steel quality and variety have increased, and the proportion of electric furnace steel has also increased, leading to an increasingly tight supply of scrap steel, especially the raw materials required for producing high-quality and pure steel, Controlling the content of non-ferrous metal inclusions and harmful elements in scrap steel through a box furnace is the foundation for improving steel quality.
The direct reduction iron does not contain these impurities and less harmful elements. The use of direct reduction iron in electric furnace production can dilute harmful elements and significantly improve the steel quality. The addition of direct reduction iron in electric furnace smelting can form carbon boiling in the melting period, form foam slag, promote the melting of furnace charge, reduce nitrogen and hydrogen content in steel, protect the furnace lining, and shorten the refining period and smelting time; The direct reduction iron has a uniform and stable composition, moderate block size, and can be continuously fed.
