Waste heat recovery in a furnace helps to increase higher efficiency because the main reason is, ... Why is the furnace used for the extraction of iron called a blast furnace? Who makes the best high efficiency furnace? ... What are the disadvantages of an industrial induction furnace in heat treatment?
Direct Reduced Iron (DRI), also known as Sponge Iron, offers an alternative steel production route to BFBOF and ScrapEAF routes. In DRI, iron ore is reduced in its solid state – unlike BF process where a liquid metal is formed during reduction. DRI can then be transformed to steel in electric arc furnaces.
Thermodynamic calculation on the smelting slag of direct recycling of electric arc furnace stainless steelmaking dust was presented. An induction furnace was used to simulate electric arc furnace smelting to recover the metals from the dust.
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 .

traditional route of steel making. Iron Ore and Coke is main raw material in this process, leading to high Carbon emission in environment. While on the other side Secondary route uses Electric Arc Furnace / Induction furnace for steel making and uses Scrap, Pig Iron and Sponge Iron (HBI /DRI) as .
Thermodynamic calculation on the smelting slag of direct recycling of electric arc furnace stainless steelmaking dust. An induction furnace was used to simulate electric arc furnace smelting to recover the metals from the dust. The elements of iron, chromium and nickel in the ingot and the components of metal oxides in the slag were analyzed.
The aluminum foil did not suffer any treatment or grindding, and they were grouped and packed in the crucible of the furnace manually. In the total, 79 processes were developed, obtaining a recovery yield of 93%. Comparisons with income from other types of scrap in different types of furnaces were made.
Scrap is by far the he most important resource, accounting for about 80% of all electric arc furnace metal feedstock (IEA, 2007. p. 128). The iron units are loaded in a basket together with limestone – for slag formation – and charged into the furnace.

The furnace charging well is connected to the melt area by channels through which molten aluminum is pumped from the melt area into the charging well. Aluminum flows back into the melt section of the furnace under gravity. Most secondary aluminum recovery facilities use batch processing in smelting and refining operations.
