In steelmaking plants, quick refractory maintenance steps are required in order to ensure a high productivity level in the continuous steel production flux. For the tundish working lining, for instance, the ideal conditions for a suitable repair includes easy deskulling, fast installation procedure, and short curing time. Considering these aspects, the present work addresses a novel refractory dry mix, which, due to a flexible binding system, could harden after only 30 minutes at room temperature, with no heating system requirement. In addition, a fast and simple disposal after use was achieved by the correct selection of additives, which provided an efficient sintering process without sticking to the tundish back lining. The monolithic material composition is also entirely water-free with very low residual carbon content, reducing the risks of any sort of elements pick-up from the refractory lining, and, consequently, helping the clean steel production.
