Problem overview and objective
The production unit at Tasso is responsible for producing cast iron bars in round, square and rectangular shapes by the horizontal continuous casting process. The receiver is responsible for holding the molten cast iron and can hold up to 3500-4000 kg of molten metal. Due to high temperature of the molten metal, there is a heat loss from both the side and top of the receiver. The objective of the project is to minimise the heat loss by optimising the design of the receiver, primarily from the top part of the receiver that comprises of a temporary insu-lated blanket.
The overall objective that this project will attempt to solve is to not only minimise the tem-perature range of molten iron going to the die-casting unit, which will help us in stabilizing our operations and improving the quality of the final product. But also help us in reducing our energy consumption and continue our progress towards becoming a more sustainable foundry.
Problem statement
The heat loss in the receiver unit takes place from the walls and the top of the receiver. The walls of the receiver immediately exposed to the molten metal is magnesia lining, which is followed by a 2mm bricklayer, and finally a steel plate that is exposed to the ambient envi-ronment. Since the top part of the receiver cannot be permanently closed as it receives the incoming melt, a temporary insulator blanket is placed at the mounting when there is no pouring happening.
The heat transfer in the receiver unit should be simulated to understand the heat loss across the walls as well as the top. Once this achieved, the candidate should propose optimised design, especially on the top part of the receiver that will result in a minimum heat loss. The optimised design of the cover can take the form of revamped geometric design of the cover or changed materials or any other operational or technological change that will optimise the heat loss.
Who are you?
We are looking for a candidate to collaborate with us in the form of a thesis project. The ideal candidate would be the one who understands the bigger picture and can use his/her trans-disciplinary knowledge on thermal modelling, material science and CAD drawings to solve a real-life problem. It is expected to do some in-house experiments during the project at Tasso where the student can validate the simulated results with the experimental findings.
