Studies on the Use of Electricity to Reduce the Consumption of Coke in the Development of Cast Iron in the Furnace

Abstract

The paper presents the studies carried out in order to reduce the consumption of the volume of coke required for the production of pig iron in the furnace. Reducing coke consumption is necessary because it is an increasingly expensive material that increases the production cost of pig iron. Internationally, for the partial replacement of coke, auxiliary fuels were generally used in the form of gas or in liquid form, and the most used turned out to be methane. This process is limited by the fact that the temperature in the furnace is difficult to ensure. The studies carried out have demonstrated that, under the given conditions, it is possible to directly introduce electricity into the crucible, the charge of the crucible presenting properties of electrical resistance that allow the application of additional electrical heating.
