Iron making in induction furnace for casting steel billets
To avoid off grades, hot metal was produced by melting the mixed scrap. In this method, the charge mix was so designed that, the metal tapped from induction furnace contains carbon in the range of 3.0–––3.5%, which was then converted into steel in EOF and was subsequently cast into billets to cater to the needs of Syria. 4)The usual practice is to charge a basket of scrap which representing from 20 to 50% of total charge, to melt that scrap partially to create a molten pool and then to feed sponge iron at a particular rate. 100% sponge iron charge is achieved by keeping a heel of molten metal (about 20–25%) in the furnace after tapping and then feeding Electric Furnace Processes SpringerLink

Molten Metal Splash and Furnace Refractory Safety
By diligently examining and treating scrap, following induction furnace safety procedures, properly training and retraining personnel, and use of automated melt shop equipment, founders can be confident their operations are as safe as possible. Wet charge materials are a serious safety hazard in all foundries.The induction stirring accelerates the transfer of heat and promotes the melting of DRI. The effect of partial replacement of scrap by DRI on various melting parameters has been studied.STUDIES ON DIRECT REDUCED IRON MELTING IN INDUCTION FURNACE

The melting time of scrap is a factor that affects the Electrical Energy (EE) consumption of the Electric Arc Furnace (EAF) process. The EE consumption itself stands for most of the total energyThe first phase of steelmaking using induction furnace melting is the scrap charging which could be done manually or by mechanical systems depending on the size and type of the induction furnace [2].

The extent of dephosphorization in the induction furnace with available DRI and steel scrap is in the range of 24.44% to 54.44% by using LD slag. Experimental result it shows that the aluminium and silicon level in the final product have increased. The acidic lining of the induction furnace may be responsible for it.Process algorithm, numerical model and techno-economic assessment of charge calculation and furnace bath optimization for target alloy for induction furnace-based steelmaking is presented in this study.

Iron making in induction furnace for casting steel billets
ES is producing 130 mm 2 mild steel billets to cater to the needs of rolling mills in Syria. An induction furnace is an electrical furnace in which the heat is applied by induction heating of metal for the production of steel [1]. Since no arc or combustion is used, the temperature of the material is no higher than required to melt it; this canfurnaces directly. For electric induction furnaces, however, the scrap metal added to the furnace charge must first be pretreated to remove grease and oil. Scrap metals may be degreased with solvents, by centrifugation, or by preheating to combust the organics. 12.10.2.2 Metal Melting The furnace charge includes metallics, fluxes, and fuels.12.10 Gray Iron Foundries U.S. Environmental Protection Agency
