Conclusions Using rig equipment a study was made of the temperature distribution across the thickness of a 460 mm periclase-spinel roof in an open hearth furnace in conditions of natural cooling, and also forced surface and deep cooling of the structure. It is shown that the cooling of the external surface cannot effectively contribute to a reduction in the roof wear. The developed method for deep air cooling facilitates a substantial increase in the temperature gradients in the layers of the refractory adjacent to the working surface of the roof, which should lead to a reduction in its wear. A quantitative analysis was made of the probable relationship between the intensity of deep cooling and the reduction in the level of scaling (spalling).
