Abstract
In electric arc furnaces, the lifetime of the taphole can be a critical factor in governing productivity and operational costs for the steelmaker. The field performance of tapholes can be investigated by developing a detailed understanding of the key material properties that govern taphole sleeve behaviour in the steelmaking process. In this application, high erosion resistance, oxidation resistance and thermal shock resistance are those key properties, and current taphole sleeve refractory material technology aims to maximize these attributes through formulation and material selection. The improvements in taphole refractory properties are expected to lead to more consistent and stable tapping times with increased taphole lifetime, reducing furnace down time and increasing productivity
