Keywords: Vacuum induction furnace, Deoxidation with carbon, Steel for petrochemistry, Oxygen activity, Total oxygen 1. Introduction A metallurgical unit composed of a vacuum induction furnace and a vacuumed crucible seems to be a prospective one for
electric-furnace, or vacuum-induction melting (VIM). The primary melting may incorporate separate degassing or refin-ing, and may be followed by secondary melting using electro-slag remelting (ESR), or vacuum-arc remelting (VAR). 5.1.1 The steel shall be fully
· Induction furnace melting The medium frequency coreless induction furnace (Fig. 4.5) is the most flexible steel melting unit and is widely used in steel foundries. Small sized scrap can be melted from cold and the furnace can be used for successive melts of widely differing analyses.

· EF deoxidation eliminates nearly all slag formation during the EF melt cycle. With DeOX Metal Treatment, slag volumes produced during the cupola melt cycle decrease close to 75%. A minor amount of slag will always be created due to the SiO 2 ash contained within coke.
Induction heating is simply a method of transferring heat energy. Induction furnaces are ideal for melting and alloying a wide variety of metals with minimum melt losses, however, little refining of the metal is possible. There are two main types of induction furnace:
99.9 %, flow rate 400 cm3/min), the sample was melted in an induction furnace at 1873 K for 1 h, and then Al (purity 99.9 %) followed by Ti (purity 99.9 %) were added in sequence with interval of 2 min to specimens 2–A and 2–C, or only Ti was added to specimen 2–B.

An induction furnace is an electrical furnace in which the heat is applied by induction heating of metal.[1][2][3] Induction furnace capacities range from less than one kilogram to one hundred tonnes, and are used to melt iron and steel, copper, aluminum, and precious metals. The advantage of the induction furnace is a clean, energy-efficient ...
· The induction furnace is an electrical furnace in which the heat is applied by induction heating of a conductive medium (usually steel scrap) in a crucible placed in a water-cooled alternating current solenoid coil. Induction coil is required to be protected from the liquid steel by isolation material called refractory.
· DEOXIDATION PRACTICE On industrial scale there are three methods of deoxidation. After refining, molten steel can be deoxidized either inside the furnace, called furnace deoxidation or during tapping in a ladle, called ladle deoxidation. For
induction furnace. Initially, the most common operations of ladle treatment were deoxidation and alloying. More sophisticated methods like vacuum degassing, chemical reheating, or injection of powdered refining mixtures have also been successfully
suspensions. Particular attention must be given to the final deoxidation treatment which is the most important phase in electric furnace steelmaking. Gas treatments can be continued during tapping and holding the melt in the ladle by
· Emission rate from an induction furnace depends upon the charge material which again depends upon the product being made from that furnace. If the product being made is a good quality casting then emissions are of the order of 1 to 2 kg/ton metal charge but if it is ingot/billet which then emission rates of the order of 10 to 20 kg/ton metal charge are normal.
