The role of carburizer during steelmaking in the induction furnace is to remove oxygen from the sponge iron which is present in the form of FeO and to provide carbon pick up in the liquid steel to the desired level. Anthracite coal and petroleum coke are the two popular carburizers being used during steelmaking in the induction furnace. Recovery of carbon depends on the size and quality of the

Sponge iron induction furnace. The sponge iron used in induction furnace should have a high metallization. This will result in a high melting efficiency. In fact, there is no possibility of using second grade sponge iron in the induction furnace due to the structure of these furnaces. While the electric arc furnace type are less sensitive to
Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal.Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting

than induction furnace operations. Laboratory experiments showed that there is a potential for increased alloy recovery and control through argon stirring with a porous plug. Argon stirring decreased mixing time by 50% and decreased the local variation in steel composition. Introduction . One of the highest costs in a melting operation is alloy additions. Therefore, if a foundry can have a
The furnace is switched on, current starts flowing at a high rate and a comparatively low voltage through the induction coils of the furnace, producing an induced magnetic field inside the central space of the coils where the crucible is located. The induced magnetic fluxes thus generated out through the packed charge in the crucible, which is placed centrally inside the induction coil.
DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using gaseous reductants (CO + H

In sponge iron making, iron ore is reduced in solid state. Unlike in the conventional steel melting processes, the gangue content of iron ore cannot be separated as a slag. Therefore, it becomes imperative to select an ore with a high Fe content and a low gangue content, to optimize yield during steel making. Apart from this, to ensure a better kiln campaign life and output, the iron ore is
