Abstract:
The primary goal in steel converter operation is the removal of carbon from the hot metal. This is achieved by blowing oxygen into the melt. The oxidation of carbon produces a lot of heat. To avoid too high temperatures in the melt cold scrap (recycled steel) is charged into the converter. The melting rate is affected by heat and carbon mass transfer. A process model for steel converter is in development. This model is divided into several modules, which are fluid dynamics, heat- and mass-transfer, scrap melting and chemical reactions. This article focuses on the development of the scrap melti

Abstract:
The article presents the results stemming from the calculation of the arc efficiency of arc steel melting furnaces during melting of scrap and metallized pellets. Furnaces that use metallized pellets are characterized by less arc efficiency and a higher electric energy consumption than similar pellet furnaces. The calculation results are confirmed by experimental investigations of energy balances of arc steel melting furnaces during melting of scrap and metallized pellets.

Abstract:
The annual cumulative quantity of high and medium alloy steel scrap has exceeded 10 million tons. Using the traditional smelting process involving electric arc refining in a smelting furnace for these scraps causes high percentages of alloy losses, which decreases the value of the alloy steel scrap and poses environmental threats. Existing studies have rarely focused on separate smelting of the scrap and oxidation behaviors of the alloying elements. Therefore, this study proposes an induction melting and electroslag remelting scheme to process the scrap. Based on this scheme, the effects of th

With the increasing of scrap usage in steelmaking processes, the melting of scrap becomes a very important phenomenon that limits the productivity and tap-to-tap time. Ice-water systems have been widely used to study the melting of scrap and alloys. In this study, the melting rate of saturated KCl solution ice spheres in gas-water two-phase plume zone are studied as a function of height of location, gas flowrate, and melt temperature. The results show that the shape of the ice sphere gradually changes firstly from spherical to elliptical, and finally becomes an irregular state. 1) The decreasi

Metallurgical aggregates, which are used for metal waste melting, are equipped with lances for blowing gaseous media. These gaseous media allow especially scrap melting and intense homogenization of the resulting melt. In connection with this, the blowing systems are developed both for blowing of gaseous media itself on the bath surface or into the melt and for blowing of the gas mixture with powdered substances.

The Linz–Donawitz (LD) converter is still the dominant process for converting hot metal into crude steel with the help of technically pure oxygen. Beside hot metal, scrap is the most important charging material which acts as an additional iron source and coolant. Because of the irrevocable importance of the process, there is continued interest in a dynamic simulation of the LD process, especially regarding the savings of material and process costs with optimized process times.

Based on the preliminary modeling study, an improved heat-transfer model has been developed in this study to further examine the viability of the oxy-fuel-fired continuous process rotary melting furnace (CPRMF) as a replacement of the electric arc furnace (EAF) in minimill steelmaking. The model treats the furnace as three domains: the freeboard space, the liquid metal bath and slag, and the refractory structure. Based on certain physical correct assumptions for the gas flow and combustion patterns, radiative exchange within the freeboard is solved by the zone method in combination with a clea

Therefore samples from the melt, slag and filter dust are taken to be analyzed by gammaspectroscopy.

Abstract:
Prediction of structural dynamics of the Electric Arc Furnace (EAF) is rather difficult, because of a number of phenomena occurring during the scrap melting process. Three large electrodes, corresponding to each phase of a AC circuit, are lowered by the main mast towards the scrap to activate the melting process, induced by the electric arc. Electric current fed to each electrode produces a strong magnetic field and applies an electromechanical force on the other electrodes. Arc voltage looks irregular upon time, even because of the scrap motion within the vessel and temperature growth. The ve

Abstract:
A significant amount of aluminum is processed by melting secondary aluminum that contains small amounts of magnesium. A major drawback of aluminum production in secondary melt furnaces is the formation of dross or aluminum oxide by the oxidation of the molten metal. Since aluminum scrap forms a major source of the metal in secondary aluminum processing, the presence of alloying elements plays a key role in the oxidation process. Here, we consider the early stage of oxidation of Al-Mg alloy, during which primarily oxidation of magnesium to magnesium oxide occurs. We have simulated the processes
