Estudo de eficiência energética em forno de percussão

Abstract

Iron manufacturing has gone through many evolutions, until you reach the steel we know today, one of the materials with the highest number of applications in industry, with great importance for the world economy. For their use, are needed many manufacturing processes, to achieve the necessary mechanical characteristics, among which we highlight the impact of heat treatment furnaces, which performs operations stress relief annealing and according CHIAVERINI (1977). The oven activity is divided into two parts, when loaded and unloaded. In both cases, the oven remains at high temperatures. In the first to meet the specified mechanical properties and the second parts in vacuo, and the remaining majority of the time. When the downloading is kept warm working temperature to eliminate the temperature and taken to avoid wetting the inside at low temperatures, which can promote cracks in the refractory lining. Thus, in the context of proposing improvements to the energy efficiency of processes in electric arc furnaces, this study was defined as a qualitative and quantitative study, using a descriptive design with a theoretical, whose methodology was based on an action research with collection data in the field, providing analyzes to define the temperatures that the furnace should remain, so that the energy consumption is minimized without compromising productivity, equipment integrity and still achieving a significant cost reduction, concatenating with the central objectives research.
