Abstract: A device for adjusting the distance of stripper chisels from a circumference of work rolls supported in chocks of a roll stand, wherein the stripper chisels are movable parallel to the rolling line in direction towards and away from the roll gap. To adapt to different operating positions and diameters of the work rolls, the stripper chisels are arranged in a horizontally displaceable stand roller table. The movement of the stand roller table is linked with the vertical movement of the bottom work roll so that the stripper chisel can be moved away from the work roll when the bottom work roll moves upward, and vice versa.

Abstract: A method and a device for winding metal strip onto a mandrel to which the metal strip is fed by a driver encompassing a bottom and a top drive roller in a driver frame. In order to regulate the driver in such a way by measuring the strip tension, the longitudinal tensile strength applied to the metal strip by the driver to control the strip run through the driver is determined by means of a strip tension measuring device which is mounted on the driver frame, in a pivot located shortly behind the bottom drive roller, and can be swiveled into the metal strip from below. The strip tension measuring device is composed of a first lever arm and a second lever arm which is hingedly mounted at the front of the first lever arm and the forward end of which is provided with a roller.

Abstract: A process and material for producing foamed slag by which the foaming of a slag with a high chromium oxide content can be achieved. An electric arc furnace is charged with a mixture of metal oxides and carbon and, below the slag at the metal-slag interface, the metal oxide is reduced by carbon and limestone and becomes thermally discordant. The occurring gases cause the slag to foam due to the formation of bubbles.
