A Process For Saving Energy And Time In Electric Arc Furnace

It is known for a long time that the reaction of oxygen with carbon, silicon, iron and many other elements is exothermic. The heat of released from these kind of reactions can decrease the time of fusion of iron and steel for metallurgical purposes in the electrical arc furnaces. By decreasing the time of fusion, we increase the rate of process and the amount of production. So, by blowing oxygen in to the furnace, we can reduce the consumption of electricity and save cost. There are many problems in the procedure of the oxygen blowing. In this project, the theoretical aspect of the oxygen blowing and its side effects into the arc electric furnaces are investigated. An oxygen blowing system into the arc electrical furnace of metallurgy department of Machine Sazi factory was also set up. This process reduced the consumption of electricity up to 22% and increases the rate of production, by reducing tap ? to ? tap time up to 15%. In this project; all oxygen blowing systems and its control were set up.
