APPLICATIONS
In modern days while moving towards green environment, it is necessary to recycle steel scraps generated from various Industrial bodies including automobile, machine shops and also from domestic usage like furniture, kitchen utilities etc. Induction furnace is a preferred method to melt the steel scrap which undergoes several treatments to convert into useful end products. South Asian Association for Regional Cooperation (SAARC) and other African countries import scrap from various developed nations to make steel although induction furnace in the most cost effective process. HeatKing™ solutions have been designed for this kind of melting process and are suitable to provide best performances using scrap as the input charge. HeatKing™ solutions provide significant value like energy saving, productivity improvement, yield improvement and alloy recovery in the scrap melting process.

India and neighbouring countries have a unique method of producing direct reduced iron (DRI) which happens by reduction of Iron ore with Coal in rotary kilns. This is quite popular in Indian sub-continent due to availability of Iron ore and Coal. This particular geography helps in producing steel in the most economical way for this region. Melting of direct reduced iron in induction furnace undergoes several challenges due to corrosive slag and higher melting temperature so that there is a need of high performing refractories. HeatKing™ solutions provide optimal lining solutions for the DRI melting by delivering values such as higher productivity, lower energy consumption, safety and Hot heal to reduce the scrap consumptions.

In many countries, stainless production is picking up due to its unique property of longer life over regular steel. In general, stainless steel melting is done either by re-melting of stainless steel scrap or making the steel with ferro-chrome addition in induction furnace. Stainless steel melting generates basic slag and more corrosive manganese that reacts with traditional refractory lining reducing its performance. HeatKing™ products offer lining solutions which are most suited for the basic slags and provide higher recovery of expensive alloying elements in the input charge.

For more and more applications, the need of special steel alloys is increasing. Recent developments in melting refining process allows to produce alloy steel induction furnace with the same quality through other competitive routes like Electric Arc Furnace. While producing high quality alloy steel in induction furnace, the refractory lining can positively impact the alloy recovery potential and lead to less refractory material inclusions in the ingots. HeatKing™ solutions are designed to meet the highest quality standards in ingots production with very low refractory inclusion and highest alloy recovery.

The usage of induction furnaces to produce special steel cast is very high in the market segment of small foundries. Here, induction furnace sizes are generally in between 50 Kg to 3000 Kg of metal. The market demand is pushing for a suitable refractory lining that can handle both acidic and basic slags. HeatKing™ solutions offer a range of suitable products for such applications which demand higher alloy recovery.
