Análise de tempos e balanço de massa do processo da aciaria de uma siderúrgica de grande porte.

Abstract

The current scenario of the national steel industry raised the search for a competitive edge in Brazilian organizations, for them to remain competitive in this scenario if there is an increase in the rigor of the management and control of the productive processes, because with the price of the steel products in the low the reduction of costs of process is of paramount importance. Therefore, the objective of this work is the statistical analysis of the process times of a steel mill of a large steel company for the comparison of the standard process times in relation to the process time prediction model already used, with the use of tools, such as mass balance, for quantification of changes, and discrete events simulation. The results of the mass balance and simulation were used as parameters for the comparison between the prediction models of process times, thus producing maximum production results for the steelmaking process. The present times, statistically analyzed showed greater production capacity than the old patterns, thus showing the lag of the forecast model of process times.
