For this equipment to perform well and mitigate damage, it is necessary to be coated with appropriate refractory materials so that they are thermally insulated. When rolling hot strips, plate reheating ovens generally use refractories (walls, ceilings, sills, doors, stringers, poles, etc.) [2]. The detonating doors of these ovens require special attention because they are in an aggressive, high-temperature environment [3]. The dry door is an alternative to replace refrigerated doors, to eliminate the recurrent problems of these, with leaks and frequent maintenance, and increase the life of the deformation doors. The use of dry door in reheating ovens of Arcelor Mittal has been advantageous, a study on its application and lifetime shows the efficiency of this port concerning others used.
