Automatic Settlement System of Liquid Steel Level Into the Tundish for Continuous Casting Machine
Munteanu, Viorel (Universitatea "Dunărea de Jos" din Galaţi, 2008)The increasing quality of steel and a reliability indices of the afferent installations need an automation system for continuous steel casting machines. This paper presents an original solution of automatic settlement ... -
Basic Mathematical Modeling of the Environmental Processes in the Lower Danube Region [I]
Munteanu, Viorel; Costea, Ovidiu (Universitatea "Dunărea de Jos" din Galați, 2007)In most environmental pollution problems, the pollutant is released to the environment by the, almost always, turbulent flow of a carrier fluid. The pollutant mixes with the surrounding fluid (air or water) and undergoes ... -
Experimental Model for Pollutants Monitoring Into the Coke-Chemical Plant
Munteanu, Viorel; Vlad, Maria; Balint, Lucica (Universitatea "Dunărea de Jos' din Galați, 2009)The Coke-Chemical plants contribute heavily to producing and emitting in the atmosphere a big amount of polluting agents. Polluting emissions diminution and situating them within the international specific standards, ... -
Improvement of Properties of Heavy Plates by Secondary Steelmaking Technologies and Rolling Conditions
Munteanu, Viorel; Bodor, Marius (Universitatea "Dunărea de Jos" din Galați, 2013)In order to obtain the mechanical and technological characteristics required for controlled rolled plates it is necessary to realize a very low content of sulphur by desulphurized mixtures using CaO-Al2O3-CaF2 and injection ... -
Increase of Converter Life by Own Slag Coating
Munteanu, Viorel; Drăgan, Viorel; Zorlescu, Dan (Universitatea "Dunărea de Jos" din Galați, 2012)This paper presents a method for the improvement of the lining life of the BOF converter by slag coating, under nitrogen pressure. Own slag coating of converter lining is put in practice after steel tapping. Dolomite ... -

Munteanu, Viorel; Sava, Simona (Universitatea "Dunărea de Jos" din Galați, 2006)The quality increase of steel continuous casting and a reliability indices of afferent installations imposes the automation systems adoption of machines of continuous casting of steel. In this paper enters original ... -
Modelling and Numerical Simulation of the Atmospheric Dispersion of Pollutants from an Integrated Iron and Steel Complex-Part I
Munteanu, Viorel (Universitatea "Dunărea de Jos" din Galați, 2010)The Iron and Steel Complex processes handle, store and undertake important amounts of raw materials (iron ores, coals, etc.) energy, fuels, waste waters, slags and other different types of wastes. These activities have ... -
Preliminary Investigations Concerning Monitoring of Water Pollution Level
Cosor (Rusu), Daniela Ecaterina; Munteanu, Viorel; Gheoghieș, Constantin (Universitatea "Dunărea de Jos" din Galați, 2009)The aim of this paper is to develop an effective tool based on artificial intelligence techniques for monitoring and characterization of surface waters. Monitoring of the pollution in the aquatic environment consists in ... -
Study of the Thermodynamic Regime at the Continuous Casting of Steel
Ivănescu, Alexandru; Ivănescu, Lilica; Cireșica, Cocindau; Munteanu, Viorel (Universitatea "Dunărea de Jos" din Galați, 2007)The paper presents the evolution of the heat exchange coefficient along the path of the continuous casting unit, as a function of the cooling water flow rate and the path length. The optimization of this thermodynamic ... -
