In the steel industry, there are some parameters that difficult to measure online due technical difficulties. these scenarios, soft-sensors, which tools aim forecasting of certain variables, play an indispensable role for quality control. this investigation, different soft sensors developed address problem predicting slag quantity and composition in electric arc furnace process. The results pro...

Abstract This paper presents a comprehensive model of an industrial electric arc furnace (EAF) that is based upon several rigorous first-principles submodels the heat exchange in EAF and practical experience from melt shop. The suited for process simulation, optimization, control applications. It assumes energy demand satisfied by six sources, arc, oxy-fuel burners, oxygen lances, combustion co...

The rapid increase of non-linear loads in the last three decades has caused electrical quantities such as voltages and currents in 3-phase distribution systems to become distorted waveforms. This paper reviews, explains and discusses some new concepts, definitions and new available theory in the unbalanced and distorted systems. The usefulness of the proposed practical definitions is investigat...

Introduction: It is important that biological and health effects from the induction of currents and fields in the body by extremely low frequency (ELF) fields are fully explored to determine the effects produced at the molecular, cellular and organ levels. The objective of this study was to evaluate the intensity of ELF electromagnetic fields and its probable relationship with hematological cha...

Combining the transformation project of certain strip steel rolling production line, the techniques process of walking beam heating furnace was elaborated in this paper. The practical application of LOS-T18-2ZC1 laser detector was elaborated. The network communication model of walking beam heating furnace control system was designed. The realization method of production process automation contr...

Powderous crystalline materials of the composition Fe3−xMnxC have been prepared by first synthesizing Fe3C via mechanical alloying in a planetary mill followed by the addition of elemental manganese and arc-plasma melting or via the classic ceramic route in an electric furnace. The milling time for the synthesis of Fe3C was significantly reduced through adjusting the parameters of the planetary...
