Investigation on the novel technology of the fine inclusion removal due to the dispersed in-situ phase induced by the composite ball explosion reaction
Abstract：In the present investigation, a novel fine inclusion removal technology due to the dispersed in-situ phase induced by composite ball explosion reaction was put forward. A composite ball with this function was designed and industrial investigation has been carried out on the base of the experimental research. The results indicate that Feeding composite ball in RH furnace is a novel technology and inclusion in the molten steel can be removed effectively. CaCO3/CaO ratio in composite ball has a great effect on the inclusion removal efficiency. More feeding times and a little feeding amount can increase the using efficiency of the composite ball. Compared with the conventional inclusion removal technology, the number of the oxide inclusion can be decreased to a lower level and the inclusion size becomes much finer. Using this novel technology, the total oxygen in the as-cast slab can approach to 6ppm.
