Production of iron ingots
One of the newest and most modern methods of steel ingot production is the use of smelting induction furnaces. Many European countries now use induction furnaces to melt metals and produce steel.
These furnaces use electric current to melt scrap iron or metal ingots, and the resulting molten material is produced in the form of steel ingots after being discharged into embedded molds. Steel ingots prepared by this method are used in factories to produce various types of rebars, angles, studs. The remarkable thing about induction furnaces is their very high melting rate compared to fossil furnaces (rotary furnaces). Other advantages of induction furnaces over old furnaces include much less space, no environmental pollution, very high efficiency, and very easy operation. Induction furnaces are produced in various capacities from low to high tonnage, which makes this new industry on a workshop-to-factory scale. Of course, in the case of high-capacity furnaces, continuous steel billet lines can be used. In this method, the production of molten material from induction furnaces is transferred to a continuous casting line and the billet is removed from it in long dimensions. The use of induction furnaces has also expanded due to the high speed of operation in the parts manufacturing industry, so that now many casting and production units are replacing old furnaces with induction furnaces, which plays an important role in increasing the profitability of these units. It is vital.
