A 2D axisymmetric two-phase model was developed to study the effect of an arc impingement on liquid metal inside electric furnace. In addition flow dynamics, covered heat transfer and magneto hydrodynamics metal. Through a parametric study, three different parameters were considered predict most important factors affecting overall behaviour process: gap, density gas, total current. Understandin...

To grow high-purity and large sizes MgO single crystals with twin-electrode DC submerged arc furnace requires that the temperature distribution be well understood and the processing temperature be precisely controlled. For the complexity of the production of MgO single crystals and the difficulty to measure the temperature inside the furnace, the temperature distribution was studied by using fi...

This paper provides results from a series of projects investigating the application of PLS to provide process engineering solutions in the steel industry. These applications involve the prediction of final product quality in a LD converter, the prediction of NOx in a reheating furnace and an analysis of the effects that changing scrap types have on final product quality in an electric arc furna...

Considerable work has been done on the development of advanced process control for the Electric Arc Furnace (EAF) steelmaking process. Historically, many control systems have been employed which rely on static heat balance calculations coupled with power input profiles to generate recipe driven control models. Steelmakers have desired to have continuous information about the gases exiting the f...

An ABB SVC Light® rated at 13.2 kV, 0-64 Mvar (capacitive) has been installed at the Gerdau plant in Charlotte, N.C., USA operating an electric arc furnace (EAF) with continuous charging for scrap-based steel production. The EAF, rated at 30/33 MVA, as well as a ladle furnace (LF) rated at 18 MVA are taking their power from a 100 kV supply grid. The fast control of SVC Light will improve the po...
