Our Research
The present work is a pioneer study on the dissolution of calcium aluminate particles in liquid oxide mixtures using the unique real-time observation approach. Experiments were conducted to provide a better understanding of the effects of various steelmaking conditions on inclusion removal during the refinement of liquid steel. A clear understanding of the dissolution kinetics of inclusions helps to optimize the current steelmaking routes and enhance the removability of inclusions. Steel with a minimum amount of inclusions has better properties from all aspects, which improves its applicability in all fields.
The ladle and tundish play an important role in removal of non-metallic inclusions such as alumina, magnesia etc. which pose problems such as ceramic nozzle clogging. Studying the inclusion dissolution phenomenon by using a High Temperature Laser Scanning Confocal Microscope (HT-LSCM) where the dissolution of single inclusion particle, such as alumina shown in the video, is observed at steelmaking temperature.
