Functional Refractory Material Design for Advanced Thermal Shock Performance Due to Titania Additions



One of the biggest challenges of refractory materials during metallurgical applications is the thermal shock performance. In terms of this work, different ways of improving the thermal shock resistance in carbon-bonded as well as in oxide-based materials by adding reactive titania powders are explored with the aid of thermal shock tests and followed by microstructure evaluation. The laboratory results obtained lead to microstructures with superior thermal shock properties and open the horizon of development of functional components such as slide gates or nozzles for clean steel technology.
