Slag and Steel Resistance of FC Steelboard

This proposal is to carry out an experimental investigation into the basic material science that controls the**duration of high temperature resistance to breakdown of vacuum formed refractory panels in contact with**molten steel and slag. A series of experiments will evaluate the breakdown mechanisms by exposing**industrially produced material to contact with two metal (steel and iron) and two slag (steel and iron)**compositions at 1600°C, followed by chemical and microstructural assessment by x-ray, optical and electron**microscopy as well as strength testing. The work will identify chemical-structural material features responsible**for degradation resistance or failure in terms of chemical dissolution, thermal stress or mechanical erosion, and**point to improvements in product design that can be implemented by the partner company, FibreCast Inc., A**Burlington, Ontario, based manufacturer of high-performance refractory products. By improving the metal/slag**containment properties of its product, FibreCast will be in a position to increase its market share and expand**Canadian output of a value added product, with increased employment and capital investment at its Burlington**operation. Canadian steel producers who use the material for lining steel processing vessels will also benefit**from the availability of high quality structural insulation boards through increased working volumes of**steelmaking vessels, reduced frequency and cost of relining, reduced temperature loss and better breakthrough**protection safety.
