  • Patent number: 8806910
    Abstract: A method for continuously removing scale from a hot-rolled carbon steel strip includes: cracking the scale on the hot-rolled steel strip; shot-blasting the cracked scale to remove the scale; deforming the hot-rolled steel strip so as to weaken the bond between scale remaining after the shot-blasting and the hot-rolled steel strip and so as to impart surface roughness to the hot-rolled steel sheet; and polishing the deformed hot-rolled steel strip to remove the remaining scale.

  • Patent number: 7386911
    Abstract: An apparatus for dislodging and removing contaminants from a surface of a machine tool. The apparatus includes an arbor, a vacuum source, a tube, and a cleaning member disposed proximate a distal end of the tube. The cleaning member contacts a surface of the machine tool to dislodge contaminants. The contaminants are drawn through the tube by the vacuum source.

  • Publication number: 20040194804
    Abstract: A method of removing iron oxide scale from processed sheet metal comprises the steps of: providing a surface conditioning apparatus; and conditioning a surface of the processed sheet metal with the surface conditioning apparatus. In general, the iron oxide scale generally comprises three layers prior to surface conditioning: a wustite layer, a magnetite layer, and a hematite layer. The wustite layer is bonded to a base metal substrate of the processed sheet metal. The magnetite layer is bonded to the wustite layer, and the hematite layer is bonded to the magnetite layer. The surface conditioning apparatus has at least one surface conditioning member. The step of conditioning the surface of the processed sheet metal includes bringing the at least one surface conditioning member into engagement with the surface of the sheet metal.

  • Patent number: 6431971
    Abstract: This invention provides an abrasive brush having strength and abrasive characteristics similar or superior to those of conventional brushes, and which allows a brush assembly having a desired width dimension and a desired brush surface hardness to be readily and easily assembled. A disk-shaped abrasive brush 1 includes a radial inner hub 5 and a radial outer brush section 3, preferably the hub 5 being integrally formed with the brush section 3. The hub 5 is provided with a flat part, a recessed part 9, 11, and a projecting part 7. When two adjacent abrasive brushes are aligned adjacent to each other, the flat, recessed and projecting parts of the abrasive brushes are engaged with each other and define a pitch between the abrasive brushes.

  • Patent number: 6321431
    Abstract: A method and device for A process for removing oxide skin from cut surfaces of a thin-walled metal strip used for preparing strip material for welded pipes. The invention comprises passing the metal strip between pairs of rotating cutting tools and applying a low self-adjusting working pressure to the cut surfaces with the tools. During this process, the temperature of the metal strip is maintained below 80° C. to prevent the oxide skin from redepositing.
