in a coreless induction furnace (gray shaded areas) The hottest area of medium and high frequency coreless furnaces is at the mid-point of the power coil. All areas of slag deposit will be at a much lower temperature than those occurring at the center of the coil. Slag can also be deposited in areas midway down the crucible lining, where insufficient metal

An induction furnace is accurate with repeatable results, safer and cost-effective way to melt precious metal bearing materials. It uses a high-temperature electric current to melt the metal with an added fluxing agent. Once the metal is molten it is stirred ensuring the
Oct 27, 2011· Air-cooled Blast Furnace SlagThe simplest treatment of the liquid slag is to lead it into a slag pit where layers build up until the pit is full. When it has fully solidified and then cooled somewhat, the slag (commonly known as air-cooled blast furnace slag or ACBFS) is excavated and transported away for further treatment (such as magnetic removal of any iron, or crushing and screening).

The induction furnace for melting sponge iron is required to have a large ratio of cross sectional area to volume so that the heat transfer is high and to keep the slag hot and fluid. The induction furnace uses the transformer principle of induction, i.e. when an electrical conductor is placed in a fluctuating magnetic field then a voltage is
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, aluminum, 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
May 24, 2018· Induction furnace is a type of electric melting furnace which uses electric current to melt metal. The principle of induction melting is that a high voltage electrical source from a primary coil induces a low voltage, high current in the metal (secondary coil). Induction heating is simply a method of transfer of the heat energy.
The slag in induction electric furnace steelmaking has poor ability to participate in the metallurgical reaction. In electric arc furnace steelmaking, the temperature of the slag is higher than that of the molten steel, and the slag has a strong ability to participate in metallurgical reactions.
Pyrometallurgical Processing of Vanadiferous Slag Pyro . The effect of slag basicity on the distribution of vanadium and iron was plasma-induction furnace at the 20 kg scale provided a solution to the problem of the.
Induction Melting An induction furnace is accurate with repeatable results, safer and cost-effective way to melt precious metal bearing materials. It uses a high-temperature electric current to melt the metal with an added fluxing agent. Once the metal is molten it is stirred ensuring the alloying conditions are fully mixedContinue reading

Coreless induction furnaces have been used in the ferrous industry for over 50 years and are now one of the most popular means of melting and holding
The most common process for granulating blast furnace slag involves the use of high water volume, high pressure water jets in direct contact with the molten blast furnace slag at a ratio of approximately 10 to 1 by mass. The molten blast furnace slag is quenched almost immediately to form a material generally smaller than a #4 sieve.
induction furnace iron slag processing. Control of Slag and Insoluble Build-up in Melting Furnaces Up in a Coreless Induction Furnace The areas of slag deposits are at a much lower temperature than the center of the furnace walls. and in the using flow-through process. Slag buildup in ductile iron treatment ladles is a very common problem at

merchant scrap will increase and additional processing ca pacities and the induction furnace system with which the formation of oxides and incorporating grey cast iron furnace slag
1. The induction furnaces are heated faster and have higher thermal efficiency. The heat is generated in the furnace (liquid steel), so the heating speed is high. In the arc furnace, the heat of the arc after the material is cleared must be transferred to the molten steel through the slag, which is indirect heating. Thermal efficiency is poor.
Induction Melting. JRI utilizes induction furnaces to melt precious metal with different structures and characteristics. A fluxing agent such as borax assists the metal to become molten and homogenous. The molten metal can be sampled using a vacuum pin tube in the molten state or drilled after the dore has been poured and slag removed.
In a coreless induction furnace, slag residuals normally deposit along the refractory walls and within the active power coil. The composition of slag varies with the type of metal being melted in a coreless furnace. The cleanliness of the metallic charge, (consisting of sand-encrusted gates and risers, or rust- and dirt-encrusted scrap
The electric induction furnace of the invention incorporates an electric arc or plasma beam generator to melt all the inorganic non-metallic material.
