Abstract
The steel ladle is fundamental to the secondary refining process. The refractories used must be designed to obtain the lowest specific consumption and the lowest possible interaction with the metallic bath. Currently, a lining with carbon (C) in chemical composition is used in the barrel of the steel ladle. The main goal of this project is to increase the performance potential of the barrel, proposing a tempered alumina-magnesia and carbon-free brick. This product has superior raw materials compared with the standard one and better compatibility with the current plant production process. The additional benefits of this new concept aim for steel quality, preservation of equipment, and savings in production costs. Another advantage of this product is the formation of the spinel phase at the hot face of the refractory, promoting brick-joint closure and minimize the metallic infiltrations within the lining.
