Although agglomeration behaviour of alumina based inclusion in low carbon steel has been widely investigated, very few studies focus on non-alumina based inclusions in high carbon steel. The usage of high carbon steel has been attracting a lot of attention due to the increasing demand for more strength and hardness. By utilizing IR furnace combined with Confocal Scanning Laser Microscope (CSLM), in-situ observation of agglomeration behaviour in liquid high carbon steel has been investigated. Agglomeration behaviour of non-alumina based oxide and CaS based sulfide particles at the surface of liquid steel has been studied in-situ. Measured attraction forces from recorded video file were of the similar order as estimated capillary forces which were calculated from contact angle. Furthermore, it was indicated that attraction forces among these inclusions were lower than those of pure alumina particles in low carbon liquid steel.
