Patent number: 9333625Abstract: A method for descaling stainless steel includes providing a descaling apparatus having wheels configured to propel a scale removing media against the sheet metal. The wheels are positioned In such a way that the scale removing media propelled from one wheel does not substantially interfere with the scale removing media propelled from another wheel. The scale removing media propelled from each wheel extends across substantially an entire width of the length of the sheet metal, and the wheels are positioned adjacent opposite side edges defining the width of the sheet metal with the sheet metal centered between the wheels. In accordance with the method, a user is induced to install at least one of the descaling apparatuses in a push/pull sheet metal processing line and process stainless steel sheet metal in the line to substantially remove all scale from the surfaces of the stainless steel strip using the descaling apparatus.Type: GrantFiled: December 5, 2014Date of Patent: May 10, 2016Assignee: The Material Works, Ltd.Inventors: Kevin C.

Patent number: 8707529Abstract: 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.Type: GrantFiled: December 11, 2008Date of Patent: April 29, 2014Assignee: The Material Works, Ltd.Inventor: Kevin C.
