Please keep the source and address of this article for reprinting: T he Development Of Electric Arc Furnace Steelmaking Clean Production Technology Using this technology, iron ore powder can be smelted into slag-free, symmetrical and nearly pure granular iron within 10 minutes. Pulverized coal directly obtains molten iron. It is a coal-based direct reduction technology that uses rotary hearth furnaces to produce high-quality pig iron jointly developed by Kobe Steel Corporation of Japan and Midland Corporation of the United States. ITmk3 (IronTeChnologyMarkm) is known as the third-generation ironmaking method. (3) MesabiNuggetITmk3 factory of Kobe Steel, Japan.Using the Casttrip process, due to the high cooling rate, short solidification time, and high drawing speed (generally 80-1500m/min), it has high productivity and can obtain extremely fine microstructures. The strip passes through the hot rolling stand. In the electric arc furnace steelmaking workshop after the company’s transformation, there is no heating device between the casting machine and the hot rolling stand. (2) The Crawfordsville plant of Nucor Corporation, USA.The designed annual production capacity is 2 million tons, which can produce strip steel with a thickness of 0.8-12.0mm and a width of 1590mm. The company has built the world's first ArvediESP endless rolling strip steel plant, including a 250t electric arc furnace, two 250t ladle refining furnaces and an ESP endless strip rolling production line. (1) Cremona ESP endless rolling strip mill of Alvidi, Italy.In recent years, some electric arc furnace short-flow steel mills using cutting-edge technology integration have been produced. Following the surging of compact small steel mills in the 1960s, it has changed the unique situation of joint enterprises. Significant technological progress in recent yearsĮlectric arc furnace steelmaking production technology has made great progress in recent years. ⑥ Dust recovery and treatment technology.⑤ Refined slag and steelmaking recycling technology.④ Development of preheating technology for electric arc furnace scrap steel.② The si removal process is adopted to reduce the amount of slag.① Electric arc furnace steelmaking uses clean energy.⑥ Electromagnetic braking and large inclusion control technology.
② Low-oxygen smelting, control the terminal molten steel Wr0≤450×10.① Increase the proportion of pure iron sources in the raw materials (such as direct reduced iron and molten iron).In addition, the clean development of electric arc furnace steelmaking technology is as follows. The development of electric arc furnace steelmaking itself is the development of clean production. It does not consume non-renewable resources and uses the cleanest energy-electricity. It is a production technology that consumes waste iron and steel materials from the society and recycles them. The clean technology includes two aspects: improving the cleanliness of steel and reducing the load on the external environment. Publish Time: 06/23 2021 Author: Site Editor Visit: 8752
