- Analysis of Dynamic Conditions of Electric Arc Furnace SteelmakingThe poor kinetic conditions of the metallurgical reaction in the molten pool have always been a technical problem in electric arc furnace steelmaking. The lack of agitation strength of the electric arc furnace steelmaking bath has a lot to do with the characteristics of the furnace type. The traditional electric arc furnace uses scrap steel as the basic raw material, mainly uses electricity, and is supplemented by chemical energy to produce qualified molten steel.ZBTECH News February 24, 2021
- 8 classification methods of electric arc furnace equipment8 classification methods of electric arc furnace equipment, how many do you know? There are many ways to classify electric furnace equipment: (1) According to the nature of the refractory material of the furnace lining, it is divided into: Acid electric furnace, alkaline electric furnace;ZBTECH News February 22, 2021
- The future development of electric arc furnace is broadThe proportion of scrap steel making steel is increasing, and the future development space is broad. my country is a big country of iron and steel production. The proportion of long-process steel making is as high as 90%. There is a huge demand for iron ore (745, 16.00, 2.19%). At the same time, the dependence on iron ore has also remained above 80%. The countries that import iron ore in my country are relatively concentrated, and most of the importing countries are in Australia, Brazil and South Africa. Among them, Australia's imports accounted for more than 60%. The total amount of Australian ore imported by China accounts for more than 70% of the country’s ore output. A large amount of dependence on imports has made our country very passive in international ore pricing. International iron ore prices have also risen all the way, which has also put pressure on domestic steelmaking costs.ZBTECH News February 19, 2021
