Reference number : GC-2017-Q4-01221, amendment number : , agreement type : G, recipient legal name : McLean, Alexander (University of Toronto), recipient country : CA, recipient province : nan, recipient city : Ontario, recipient postal code : nan, program name english : Engage Grants for universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : Continuous casting of molten steel is one of the most significant technological innovations in the field of_x000D_
steelmaking within the last 60 years. However, blockage or clogging of the refractory submerged entry nozzle_x000D_
which protects the steel from atmospheric oxidation during transfer processes is a serious problem due to the_x000D_
adverse effects on the casting operation and quality of the cast product. In collaboration with Gerdau Whitby,_x000D_
the proposed study is aimed at characterizing materials deposited on the walls of blocked nozzles, investigating_x000D_
the possible sources of these materials, and evaluating the effect of operational parameters on the formation of_x000D_
clogging. Gerdau is the leading company in the production of long steel specialty products in the Americas and_x000D_
one of the world's major suppliers. Gerdau's North American business divisions serve the construction,_x000D_
automotive, agricultural, real estate and energy markets through a vertically integrated network of steel mills,_x000D_
recycling operations, and downstream processing facilities. The steel plant in Whitby, Ontario is one of three_x000D_
Gerdau mills operating in Canada and employs approximately 500 people. Gerdau Whitby transforms scrap_x000D_
metal from about 240,000 old cars a year into special steel products including beams and piling, rebar, special_x000D_
bar and wire rod. The objectives of this project can be defined as follows: 1) Investigate nozzle blockage_x000D_
constituents using advanced characterization techniques. 2) Relate the results to the inclusions found in steel_x000D_
samples obtained at different stages during the steelmaking and casting processes. 3) Evaluate the relative_x000D_
effectiveness of modifying operational parameters such as steel composition, casting temperature, refractories_x000D_
and liquid steel flow, in order to eliminate nozzle blockage problems. The overall aim of the project is to_x000D_
generate a bank of new knowledge and facilitate technology transfer between academia and the industrial sector_x000D_
that will result in improved steelmaking processes, higher quality product and reduced treatment time. An_x000D_
additional benefit will be the training of students in metallurgical chemistry and materials characterization_x000D_
which in turn will boost excellence in science and engineering within Canadian-based organizations., program purpose french : Continuous casting of molten steel is one of the most significant technological innovations in the field of_x000D_
