The industrial application of an aluminum wire injector for ladle metallurgy

Abstract Low and inconsistent recoveries of aluminum in the production of aluminum-killed steels triggered an extensive research program on the aluminum dissolution kinetics at McGill University. This research program led to the understanding of the melting kinetics and the hydrodynamics of making additions to liquid steel. It showed the necessity of gradually releasing liquid aluminum at the bottom of the ladle to increase aluminum recoveries.This knowledge was verified in practice at Sidbec-Dosco, where a prototype aluminum wire injector was developed and installed for the first time in Canada. The industrial application showed the validity of the theoretical and experimental results and provided further data for the mathematical modelling of the process.The development of the theoretical understanding, the industrial results, and the interaction between university and industry are presented.
Keywords: Technology, Wire injectors, Aluminum, Ladle metallurgy, Sidbec-Dosco, McGill University, Steel, Melting kinetics, Force monitoring.

Summary: A program of evaluation of in-mould electromagnetic stirring on the product of a straight-mould, billet continuous casting machine has been carried out. The effects on macrostructure, surface and internal quality, chemistry segregation and mechanical properties on carbon, low-alloy and resulphurized, free-machining steel billets and rolled bars are discussed. Operational aspects as a result of in-mould stirring are highlighted.

Summary: This paper will describe how cultivator shanks are made in one company and how the manufacturing was studied with a view to increasing product consistency and reducing manufacturing cost. The product, which is used extensively in the agriculture industry, was analyzed to determine which geometric parameters optimized its design and whether there was justification for the great variety of styles and shapes that are available in the market. Finally, an extensive series of field trials were...

Summary: In addition to the actual energy consumed, billing is dependent on the peak load and the power factor. The lower the power factor goes, the higher will be the penalty the consumer pays. The principles of a power factor regulator, the two ways of improving the power factor and methods for calculating the capacitor values required will be described.The rate structure of the utility company is founded on three cornerstones: the energy consumed during a given period of time and two penalties...

Summary: Tailings in the mining and smelting industry are reject products of the refining process which are deemed too deficient in native ore to warrant smelting. They are essentially finely ground rock materials which have been moved by alluvial suspension from the site of crushing to a deposit site. It is realized that components of flotation chemicals used in specific gravity separation may become part of the tailings and also that sewage sludge or other materials may be added at some stage to the...

Summary: The Snow Lake massive sulphide deposits are hosted by Aphe-bian volcanic rocks of the Flin Flon - Snow Lake greenstone belt, which in this area were deformed and metamorphosed to the amphibolite fades during the Hudsonian orogeny. All the known deposits occur infelsic rocks a short distance below the contact with an overlying mafic rock unit.The Stall Lake copper deposit occurs close to the top of an explosive felsic volcanic sequence. Rocks stratigraphically underlying the deposit have been...

Summary: Canada's largest known chromite deposit occurs in a layered intrusion in the Bird River area of Manitoba. However, numerically most of the chromite occurrences are in the Appalachians. Few, apparently minor, occurrences are also known in the Cordillera.In the Appalachians, chromite occurs as lenses and pods in dunite; they are of "podiform" type. The individual concentrations vary in size from a few pounds to tens of thousands of tons. Locally, chromite concentrations form discontin...

Summary: The Nemeiben Lake ultramafic complex, in the Churchill Province of the Canadian Shield in north-central Saskatchewan, is a small 1.6-km circular plug largely composed of high-alumina pyroxene cumulates forming a series of grossly concentric layers of clinopyroxenite, websterite and wehrlite. Minor dunite and gabbro are present in the northwestern part ofthepluton.Disseminated primary magmatic pyrrhotite, pentlandite, chalcopyrite, magnetite and chromite occur throughout the intrusion....
