Rheological and Thermomechanical Behaviour of Steel Fiber Reinforced Carbon Containing Castables
Rheological test results on alumina-magnesia castables, containing extruded flake graphite pellets, as well as steel fibers are considered at first. After being fired at different temperatures, thermomechanical properties of such castables containing either carbon steel or stainless steel fibers have been determined, at room temperature, as well as at temperatures up to 1100°C. Those results indicate that the use of fibers improves the performances of carbon containing castables at intermediate temperatures (800 º - 1100 °C), increasing the work of fracture by 50% at 1100 °C and by 10 fold at room temperature.
