Resumo

Hot stoves are essential components in ironmaking plants as they are responsible for heating the air used in blast furnaces. The failure of refractory systems, in a fast-paced industry, creates demand for reliable repairs that offer the shortest timeline. Therefore, innovative solutions must improve the refractory design and installation methods to repair older, traditional refractory systems promptly. An alternative design with monolithic materials was successfully implemented in 2020 and 2021 at stove D1 and D3, and currently stove C4 at Burns Harbor. Failure of the traditional (brick) hot stove refractory system led to the casting of a complete monolithic dome and large sections of the walls. A post-construction analysis will demonstrate the validity and feasibility of the design.
