    Abstract: A method of improving the surface quality of a continuously cast slab, particularly a thin slab having a maximum cast thickness of 100 mm, wherein the slab is covered with a casting slag film and a layer of scale, and wherein the slab is descaled after casting and is rolled in a finishing train. A reaction agent, which is different from water, is applied onto the slab prior to descaling or during descaling. The application of the reaction agent may be preceded by a conventional hydraulic, mechanical or pneumatic removal of the layer of scale which covers the slab.

    Abstract: The present invention provides a descaling system for hot strip or plate mills. The descaling system includes upper and lower spray headers which are offset from each other along the pass line. Each spray header is adapted to direct a high-pressure water spray on the metal product to descale the upper or lower surface thereof. The upper and lower spray headers are offset at a distance greater than the length of the product, whereby the spray headers can be sequentially, separately used. The spray headers are coupled to a common drive pump.

    Abstract: A descaling tool for use with a reciprocating hammer for removing foreign substances from metal, wood, stone, or the like. The tool is comprised of an elongated shank, one end having an adapter for receipt into a reciprocating hammer, the other having a bore therein for receiving a bundle of elongated, resilient descaling members. The shank is encased by a sleeve and handle assembly which is used to adjust the exposed portion of the descaling members.
