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 |
20150052717 | METHOD AND DEVICE FOR DESCALING A SCALED METAL STRIP - The invention relates to a method for descaling a scaled metal strip, in particular a hot-rolled metal strip with a thickness of more than 1 mm, for example 1.2 mm to 16 mm. The strip is guided around at least two straightening rollers which are arranged one behind the other in the strip running direction and undergoes an alternating bending in the process. At least one of the straightening rollers can be positioned transversely to the strip running direction. The method is characterized in that the strip is unstressed or is under a low tensile stress of less than 10% of the yield strength of the strip on the inlet side upstream of the straightening rollers, and the diameter of the straightening rollers, the spacing between same in the strip running direction, and the positioning of the rollers transverse to the strip running direction are selected while taking into consideration the strip properties such that expansions and compressions of at least 2%, preferably at least 3%, are produced in the course of a first plastic bending process and a second plastic bending process on the strip upper face and on the strip lower face for the purpose of descaling. | 02-26-2015 |

20100218354 | METHOD AND APPARATUS FOR REMOVING SLAG AND BURRS FROM A METAL SURFACE - A tool for removing slag from a flame-cut edge of metal includes a downwardly facing cup containing a plurality of steel balls. Only a portion of each ball extends from the lower end of the cup. A radially outer wall of the cup slants from a first position at its upper end to a second radially outer position at its lower end. As a result, when the cup rotates, centrifugal force urges the balls downwardly with a force that is proportional to the speed of rotation. As the cup moves over slag, lateral impact from the balls remove the slag. Because the balls are not connected to surrounding structure, they are free to rapidly move upwardly in the cup in response to hitting the edge of the cut. Consequently neither the edge nor the surface of the metal is peened or otherwise marred or disfigured. | 09-02-2010 |
20130180092 | CONE NUT DECOKING MACHINE - A work station for cleaning a cone nut includes a work bench comprising a bench top, a lathe arranged on the bench top and configured to rotate a cone nut, and a cleaning unit arranged on the bench top adjacent to the lathe and configured to clean the cone nut. | 07-18-2013 |

20080235928 | METHOD AND APPARATUS FOR REMOVING MATERIAL FROM A SURFACE OF A METAL PROCESSING CHAMBER - Methods and apparatus for removing condensed metal from the surfaces of metal processing chambers, such as, a vacuum induction metal (VIM) furnaces having, for example, condensed Mg or Ti, are disclosed. The methods and apparatus provide a robotic arm end positioned in the furnace having a nozzle operatively connected to a source of dry ice. The robotic arm end directs a stream of dry ice particles against the surface of the furnace to displace condensed metal. The displaced metal is collected for reuse or disposal. Aspects of the invention provide a safe and automated process for cleaning process chambers and recovering metal that can typically be dangerous when performed by conventional methods. | 10-02-2008 |

20090070976 | Non-Pneumatic Scaler - A non-pneumatic scaler includes a linear motion gearbox and an electric motor in communication with the gearbox for selectively actuating it. An implement is removably coupled to the linear motion gearbox such that actuation of the gearbox causes the implement to oscillate. A housing contains the linear motion gearbox such that the implement extends partially outside the housing. A rechargeable battery is coupled to the housing for supplying power to the motor. The scaler includes a trigger for actuating the motor. Another input device is included for varying the rate of oscillation of the implement. One or more light emitting diodes may be mounted to the housing for illuminating a work area. The scaler may include a force transmitter that transfers the motor's force to cause the implement to rotate.
