Abstract: A method for operating a system of the iron and steel industry for producing a metal product with participation of a severing or forming device. The actual value of an indicator be calculated over a length section of the metal product for the metal product to be produced. The indicator represents the resistance of the metal product to severing or forming processes. The calculated actual value pIst for the indicator p is then compared to a predefined threshold value. The severing or forming also only actually takes place when the actual value of the indicator of the metal product is less than the threshold value. If a comparison should show that the actual value of the indicator is greater than the threshold value, before the severing or forming of the metal product, a local processing of the metal product is performed in the corresponding length section.

Abstract: A roller for a roller hearth furnace, the roller including a water-cooled, rotatably mounted carrying axle on which a plurality of support rings are arranged at a spacing from one another. In the axial region between and next to the support rings, the carrying axle is provided with insulation composed of a fiber material and configured with protection of the outer circumference of the fiber material from the environment. In the case of insulation constructed from ring-shaped punched parts, the insulation arranged in the axial region between and next to the support rings is composed of circular or ring-shaped punched fiber parts. The protection is configured as ring-shaped insulating disks composed of a more resistant material than that of the punched fiber parts, and at least one punched fiber part is provided in each case between two insulating disks.
