This invention is of fresh source that finds wide application in industrial & domestic application saving considerable amounts of energy. Induction Melting Furnace has reduced some disadvantages that were hard to control in arc furnace.
Adhesive salting, paint drying, induction brazing, joining, induction melting, iron casting, foundries are a lot of the areas of application. These furnaces are considered to suit variety of application. Available in different sizes & capacities, these furnaces have characteristic types, like high chemical toughness, high refractory properties, low blend losses & change best metal quality free of impurities.
However, the induction progression usage in foundry lack purifying volume and supplies charged must be free of corrosion products. This will main to loss of alloy fundamentals due to oxidation and must be added again to the melted material. The frequency of induction furnace is reliant on the melted material and the speed as high frequency furnace is faster in melting the charge as against the lower regularity furnace creates more commotion in molten stage. Strangely, there will be humming, the field of which is a sign to identify the working power level of the Melting Furnace alerting the operator.
The application of induction melting furnace in steel industry is phenomenal. Both high & medium frequencies are popular in steel making. Mild steel, Stainless steel, Alloy steel of lots of results are a quantity of the types that are usually manufactured by Induction Melting Furnace in steel industry. Other applications are melting scrap, direct reduction of iron, alloy making etc.
Direct reduced iron posed an issue in carbon adjustments till the chemistry of the melt turned out to be under control by virtue of these furnaces. Using this knowledge, continuous castings of billets or rolling mills to make bars are positively done.
As compared to electric arc furnaces, Induction Melting Furnace consume less power. The intractable quantity employed is also low. The cost of electrodes is inexpensive. Initial investment on plant & machinery is also much less. These economical advantages in the production of steel by employing induction-melting furnace make this popular.
All input metals are chemically examined before accusing to keep control of the arrangement of the finish product. Fraction of scrubber iron in the charge is adjusted depending on the high carbon, sulphur & phosphorous content that will be identified in chemical analysis. When 80% of the process is through, a sample is tested to make optimistic the carbon percentage. If it is found to be high more sponge iron is added. If carbon is found to be less then forged iron scrap & turnings are added. This is how the configuration is controlled. Since there is no energetic arcing, the iron is subjected to lesser oxidation keeping the losses to the extreme. Spectrometer usage help control the chemical composition in the production of low alloy steel by Induction Melting Furnace.
Stainless steel is produced before making mild steel & the raw material is removed with molten metal to which liquid elements & compound are added as it progresses. Ferro-alloy is added while the mild steel scrap is melted & this molten metal is then refined. Special forged iron, stainless steel used for tools are also made in these furnaces. The economy & elasticity of these furnaces have created an everlasting demand for this induction melting Furnace.
