  • Refractory lining structure
    Patent number: 11440089
    Abstract: A refractory lining structure for a metallurgical vessel is characterized by at least one elongated expansion joint formed in and extending through the surface of the working lining in a substantially vertical direction. The elongated expansion joint accommodates thermal expansion of the working lining in a metallurgical vessel such as, for example, a tundish during preheating for a continuous casting operation. The elongated expansion joint decreases crack formation, delamination, and spalling of the working lining from underlying back-up linings and/or safety linings in metallurgical vessels during preheating and use, while still facilitating metal skull removal after the completion of metallurgical operations.
    Type: Grant
