This paper deals with the development of scale on five different grades of steel as it would form on the slab surface in a reheat furnace. The scale development rate and properties are evaluated. This work is particularly interesting in that the influence of oxygen enrichment in the burner and the stack oxygen concentration on the steel scaling is presented.

Summary:

Steel scaling tests have been performed in a research furnace utilizing an oxygen-enriched, low NOX, burner.  This work was performed in conjunction with a study of the combustion characteristics for the Canadian Gas Research Institute (CGRI) low NOX burner.  The furnace (a facility of the Centre for Advanced Gas Combustion Technology (CAGCT)) was fired with the burner mounted in a sidewall configuration similar to the geometry encountered in steel reheat furnaces.  Scale habit, intactness, adhesion and oxidation rates were examined for five grades of steel over a range of stack oxygen concentrations (~0.8% – ~4.3%) and oxygen enrichment levels (0 – 90%) at 1100°C.  Steel grade had the largest effect on scaling properties examined in this work.  Within the tests for each grade, stack oxygen concentration had the largest effect on the scaling properties while oxygen enrichment level had only a small effect.

Key Words:
steel scaling, reheat furnace, low NOX burners, oxygen-enrichment

Publication in the Journal
The Editor-in-Chief would like to remind all potential authors that publication in the Journal is open to all. If you have interesting results to publish in the field of, or related to, industrial combustion, we invite you to prepare a paper according to the guidelines given in the Author’s Guide on the website (http://www.journal.ifrf.net/).

Papers may be regular “articles” (typically up to 20 pages) or Communications (typically up to 4/5 pages). Review papers can of course be longer. Remember that figures and graphics in general can be in full color. This advantage should be encouraged.

All manuscripts and associated files, proposed for publication should be sent by the Corresponding Author in a compressed/zip file, as an email attachment to journal@ifrf.net. This file should include a statement that the proposal’s content is unpublished material that has not being submitted for publication elsewhere. When an article by the author(s) is cited in the proposed article as “in press”, a copy of this article should accompany the proposed article and should be included in the compressed file.
The Editor-in-Chief looks forward to receiving your proposals.
