Induction Furnace - A Review

5) Molten Metal : The molten metal is the desired output of the Induction furnace. The quantity depends upon the capacity of the furnace, and the quality depends upon the raw material and alloy composition. The tapping temperature depends upon the type of steel, as well as the distance of end use of the molten metal.

Materials needed for Steel Production in Basic Oxygen Furnace

Oct 16, 2015 · Limestone is commonly used to cool the bath if the turndown temperature is higher than the specified aim. When limestone is heated, the endothermic calcining reaction occurs producing CaO and CO2, causing a temperature drop in the BOF converter. The extent of the temperature drop just before tap depends on the heat size and the condition of the slag.

Induction furnace - SlideShare

Nov 28, 2014 · Definition.  Electric induction furnace is type of melting furnace that uses electric current to melt the metal. Once molten, the high frequency magnetic field can also be used to stir the hot metal, which is useful in ensuring that alloying additions are fully mixed into the melt.

Blast furnace - Wikipedia

In a blast furnace, fuel (coke), ores, and flux (limestone) are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with oxygen enrichment) is blown into the lower section of the furnace through a series of pipes called tuyeres, so that the stone reactions take place throughout the furnace as the material falls downward.

Induction furnace - Wikipedia

An induction furnace is an electrical furnace in which the heat is applied by induction heating of metal. Induction furnace capacities range from less than one kilogram to one hundred tonnes, and are used to melt iron and steel, copper, aluminium, and precious metals. The advantage of the induction furnace is a clean, energy-efficient and well-controllable melting process compared to most other means of metal …
