The
principle used in induction furnace is comparable to that of the functioning of
transformer. A method in which electrical conductors gets heated via currents
induced by a fluctuating electromagnetic field. This innovation is of recent
origin that finds wide application in industrial and domestic application
saving substantial quantities of energy. Induction furnace has minimized
several disadvantages which were difficult to control in arc furnace.
Adhesive
curing, paint drying, brazing, soldering, melting, iron casting, foundries are
some of the areas of application. These furnaces are designed to suit range of
application. Offered in different sizes and capacities, these furnaces have
exceptional features, such as high chemical durability, high refractory
properties, very low alloy losses and evolve premium metal quality free of
impurities.
However,
the induction process usage in foundry lack refining capacity and substances
charged needs to be free of oxidation products with Ferro Alloys Exporter in India. This will result in loss of metal elements due to
oxidation and has to be added again to the molten material. The frequency of
induction furnace is dependent upon the melted material and the rate as high
frequency furnace is significantly faster in melting the charge as against the
reduced frequency furnace generates more turbulence in molten stage. Oddly,
there will be humming, the pitch of which can be an indication to identify the
operating power level of the induction furnace alerting the operator.
The
application of induction furnace in steel industry is phenomenal. Both high and
medium frequencies are popular in steel making. Mild steel, Stainless steel,
Alloy steel of grades are some of the types which are generally manufactured by
Induction Melting Furnace in steel industry. Other applications are melting
scrap, direct reduction of iron, metal making etc..
Direct
reduced iron posed a problem in carbon adjustments till the chemistry of the
melt turned out to be under control by virtue of these induction furnaces.
Using this technology, continuous castings of billets or rolling mills to make
bars are successfully done.
As
compared to electric arc furnaces, induction furnaces consume less power. The
refractory quantity employed also is low. The cost of electrodes is economical.
Initial investment on plant and machinery also is much less. These economical
advantages in the manufacture of steel by employing induction-melting furnace
create this very popular.
All
input metals are chemically analyzed before charging to maintain control of the
composition of the end product. Percentage of iron in the charge is adjusted
depending upon the high carbon, sulphur and phosphorous content which will be
known in chemical analysis. When 80% of the process is a sample is tested to
guarantee the carbon percentage. If it's found to be high more sponge iron is
added. If carbon is found to be less then cast iron scrap and turnings are
added. This is how the composition is controlled. Since there is no arcing, the
iron is subjected to lesser oxidation keeping the losses to the minimum.
Spectrometer usage help control the chemical composition in the production of
alloy steel that is non by Induction Melting Furnace.
Stainless
steel is produced before making mild steel and the raw material is purged with
molten alloy to which liquid elements and metal are added as it progresses. Ferro Alloys Supplier is added while the mild steel scrap
is melted and this molten metal is then refined. Special cast steel, stainless
steel used for utensils will also be made in these furnaces. The economy and
versatility of these furnaces have created an everlasting demand for these
induction furnaces.
Ferro Alloys Exporter in India makes it easy for
you to get the Alloys, you can purchase them from Nishit Thermit Alloys Pvt Ltd.
