20110130075 | Method of Producing Rust Inhibitive Sheet Metal Through Scale Removal with a Slurry Blasting Descaling Cell Having Improved Grit Flow - A method is provided for removing iron oxide scale from sheet metal and producing a sheet metal surface with rust inhibitive properties. The sheet metal is advanced through the descaling cell and a slurry mixture is propelled against at least one of the top surface and bottom surface of the sheet metal across the sheet metal width as the material is advanced through the descaling cell. The rate of slurry impact against the at least one of the top surface and bottom surface of the sheet metal is controlled in a manner to remove substantially all of the scale from a surface of the sheet metal, and in a manner to create a passivation layer on the descaled surface of the sheet metal. The passivation layer comprises at least one of silicon, aluminum, manganese and chromium and inhibits oxidation of the descaled surface of the processed sheet metal. | 06-02-2011 |

20100146757 | Method and Apparatus for Breaking Scale from Sheet Metal with Recoiler Tension and Rollers Adapted to Generate Scale Breaking Wrap Angles - A metal processing apparatus comprises a scale breaker apparatus having a plurality of rollers positioned in a staggered arrangement and engaging first and second surfaces of sheet metal. The staggered arrangement creates clearances between the rollers of the first and second surface rollers sufficient to enable the sheet metal to conform to a portion of an outer periphery of at least one of the rollers while passing between the first and second surface rollers under a tensile force. The metal processing apparatus further comprises a recoiler adapted to coil the length of sheet metal. The recoiler subjects the sheet metal passing through the scale breaking apparatus to a tensile force sufficient to conform the sheet metal to a portion of the outer periphery of at least one of the rollers with a wrap angle sufficient to break scale from the sheet metal. | 06-17-2010 |
20090002686 | Sheet Metal Oxide Detector - An apparatus for detecting residual oxide or scale present on a metal surface following pickling or mechanical processing of the metal surface to remove scale makes use of laser light that is reflected off of the metal surface, a reflection detector that detects the absolute reflectivity and polarization of the reflecting laser light, a roughness measurement sensor, and a computerized control system that uses combinations of the information from the three sensors to provide an indication of the scale remaining on the metal surface. | 01-01-2009 |
20080216925 | METHOD AND APPARATUS FOR PRODUCING SCALE-FREE SHEET METAL - A method and apparatus for strip casting sheet metal and then conditioning the surfaces of the sheet metal strip to remove iron oxide scale employs first brushing the surfaces with stainless steel brushes to remove the scale without requiring pickle and oil, and then brushing the surfaces with aluminum oxide brushes to further clean and smooth the surfaces of the cast metal strip. | 09-11-2008 |
