Railway tank cars are constructed from TC 128 steel plates, a design that has not changed for more than 50 years. The Lac Megantic rail disaster in 2013 refocused the attention of Canadians on the safety aspects of tank car design and operation, but not so much on the actual properties of the steels used to build them. In this project, we will explore the potential of modern advanced high strength steels as a replacement for TC 128. In particular, significant improvements to the tank wall puncture resistance will be targeted. New alloys will be designed using the latest scientific knowledge.
Over 70% of tasks in manufacturing are still manual; therefore, over 75% of variation in manufacturing comes from human beings. Human errors were the major driver behind $22.1 billion in vehicle recalls in 2016. Currently, when plant operators want to gain an understanding of their manual processes, they send out their highly-paid industrial engineers to run time studies. These studies produce highly biased and inaccurate data that provides minimal value to manufacturing teams.
The ultimate goal of this project is to develop a fundamental understanding of inclusion evolution during a particular refining process in secondary steelmaking unit. The particular focus is firstly on developing a detailed characterization of the inclusions formed during refining in the Stelco Ladle Metallurgy Facility, and secondly on adapting the existing McMaster ladle metallurgy/inclusion model for the Stelco facility. Ultimately this is expected to achieve better process and product control. Inclusions, depending on their size and type, may profoundly affect steel properties.
This research is an attempt to understand a heat transfer challenge encountered in the Glen Dimplex electric baseboard heaters in details and provide recommendations to resolve that. This baseboard heater uses electricity to heat up an internal element which is designed to transfer the heat to the room?s air via a series of thin aluminum plates called fins. The poor heat transfer from heater fins to air results in low efficiency of the heater as well as the unwanted physical deformation of fins by thermal expansion.
Firefighting water additives are a mixture of chemicals that are mixed with water to more effectively extinguish fires (i.e., residential, industrial, forest fires). The use of these additives is likely to increase in fighting forest fires due to the projected increase in forest fire occurrence and intensity due to climate change. Ingredients of firefighting water additives used in the past were found to be persistent and detrimental to the environment.
Metal-based direct energy deposition processes, such as robotic welding and laser powder fed additive manufacturing, ideally require feedback sensing of the deposition quality using vision detectors. Image processing algorithms are challenging to develop due to changing process operating conditions. Despite challenges, implementing in-process image processing algorithms is beneficial for traceability and quality assurance, for calibrating process models, and for developing closed loop control algorithms which are able to maintain deposition quality within acceptable quality margins.
Intern will significantly benefit in terms of knowledge generation and implementation from this research project by learning novel process to shape and modify biopolymer. After successful completion, the intern will learn process to scale up the product to real life application such as fishing line and nets. Plantee Bioplastics will be able to bring the modified product to market and capitalize on research done by the intern. This project has capacity to change the negative public perspective on plastics by bringing in market an improved fishing line and n
Coming into force in October 2019, amendments to the Canadian Cannabis Regulations will introduce guidelines governing the legal production and sale of cannabis-infused extracts, edibles, beverages and topicals. These new products are at the forefront of the natural health product (NHP) and consumer packaged goods (CPG) industries, but challenges associated with their formulation, production and stability are quickly mounting.
The Ladle Metallurgy Furnace is used for adjustment of chemical composition and temperature, and control of tiny particles called “inclusions”. Controlling inclusions is carried out by adding calcium to modify the solid alumina or magnesium aluminate inclusions to less harmful liquid inclusions.
During ladle process, reaction of top slag, steel and inclusions occur simultaneously. Therefore, establishing a model to describe ladle process is indeed a challenge.
This project will create novel goat milk-based products and test their health effects in healthy adults. Interest in goat milk is increasing, mainly due to two market trends: consumers’ new taste trends for niche/ethnic products, and the perception of goat milk having added health properties. Goat milk is perceived as having intestinal anti-inflammatory effects and improved digestive properties compared to bovine milk, due to the unique functionalities of its oligosaccharides and triglycerides.
