The state-of-the-art magnesia-based dry vibrateable tundish linings are predominantly bonded by resin. However, besides high energy consumption, the pyrolysis of the resin-containing lining during the tundish heat-up process generates hazardous gases and carbon residues, resulting in an unwanted carbon pick by the molten steel after the finished ladle treatment.Hence, the aim of this study was to develop novel carbon free binder system, therefore combine acid-based with thermally activated binder systems. Their influence on the physical and mechanical properties were investigated. Additionally, utilizing a unique steel casting simulator, the influence of newly developed lining compositions on the steel quality compared to a reference binder system was tested and analyzed. The influence on the inclusion population in the molten steel and the steel quality was evaluated.Newly developed compositions showed no significant influence on the steel cleanliness, only a minor change in the population could be detected. |
