20100192655 | CLEANING DIES FOR HOT FORMING OF ALUMINUM SHEETS - In substantial volume production operations involving hot blow forming or hot stamping of aluminum alloy sheet workpieces, debris largely comprised of particles of aluminum alloy material adheres to critical forming surfaces of the heated steel tools. This debris mars forming surfaces and causes defects in aluminum alloy parts formed against them. Such aluminum-rich debris may be reactively transformed to change its adherent properties and removed from tool surfaces without removing the heated tool from production. In one embodiment, a hot sacrificial magnesium sheet may be formed on the tool(s) to alloy with aluminum debris and carry it from the forming surface. | 08-05-2010 |
20100199735 | Device For Adjusting the Distance of a Stripper Chisel - A device for adjusting the distance of stripper chisels from a circumference of work rolls supported in chocks of a roll stand, wherein the stripper chisels are movable parallel to the rolling line in direction towards and away from the roll gap. To adapt to different operating positions and diameters of the work rolls, the stripper chisels are arranged in a horizontally displaceable stand roller table. The movement of the stand roller table is linked with the vertical movement of the bottom work roll so that the stripper chisel can be moved away from the work roll when the bottom work roll moves upward, and vice versa. | 08-12-2010 |
20110247382 | METHOD AND DEVICE FOR DESCALING A METAL STRIP - The invention relates to a method for producing flat products of steel from continuously cast slabs having a large or medium thickness or from thin bars, which are compressed and subsequently run through a blooming train and a finishing train. The invention is characterized in that the flat products are descaled on their strip edges prior to compression. The method is carried out in a rolling train which comprises at least a first compression device ( | 10-13-2011 |
20110308289 | PROCESS AND RELATED PLANT FOR PRODUCING STEEL STRIPS WITH SOLUTION OF CONTINUITY - A process for manufacturing steel strips with solution of continuity. The steps of the process include a continuous casting step for thin slabs with a high “mass flow,” a shearing step and subsequent heating in furnace, followed by a multiple stand rolling step with the average temperature of the product at the inlet of the rolling mill being higher than the surface temperature, which is equal to at least 1100° C., lower than that measured in the inner central area by about 100° C. A plant is also described for the accomplishment of such process where at the inlet of a furnace, possibly of the induction type, combined with a temperature maintaining tunnel a shear is provided for cutting into pieces a slab coming from continuous casting with the distance between the outlet of the continuous casting and the inlet into the finishing rolling mill is not greater than 100 m. | 12-22-2011 |
20120036909 | METHOD AND DEVICE FOR CLEANING SLABS, THIN SLABS, PROFILED ELEMENTS, OR SIMILAR - A method for removing loose scale and other foreign matter from the top and/or bottom face of a cast product with the aid of flowable media which are sprayed onto the cast product by a cleaning device having at least one spraying apparatus that is disposed above the cast product and at least one spraying apparatus that is arranged below the cast product. According to the method, the amount of media and/or the effective width and/or the pressure of the media is/are controlled separately and independently of time for each spraying apparatus. | 02-16-2012 |
20120103044 | BEAD WIRE MANUFACTURING METHOD AND MANUFACTURING APPARATUS - A bead wire manufacturing method/apparatus includes a descaling step/device for removing oxide on the surface of a wire rod, a coating liquid adhesion step/device for adhering a coating liquid to the wire rod, wiredrawing steps/devices for performing area reduction workings on the wire rod, and a bluing step/device for bluing the wire rod having been raised to a high temperature through the area reduction workings, in a temperature range of 350° C. to 480° C. Thus, the wire rod having been raised to a high temperature through wiredrawing is blued without being cooled down to effectively utilize the temperature retained therein, so that the method/apparatus is little in energy loss. | 05-03-2012 |
20130074560 | METHOD OF TREATING A METAL ELEMENT FOR AN AUTOMOBILE - A method for treating a metal element for an automobile includes hardening the metal element so as to obtain a press hardened metal element. Scale from the press hardened metal element are removed by placing the press hardened metal element in an ultrasonic liquid and preforming an ultrasonic process thereon so as to obtain a de-scaled press hardened metal element. The ultrasonic liquid is an aqueous solution comprising an organic carboxylic acid in a concentration of from 0.1 to 10 vol.-%. The de-scaled press hardened metal element is coated in a coating process with an anti-corrosion coating. | 03-28-2013 |
20130192325 | Roll Cleaning Apparatus and Method - A roll cleaning apparatus having a cleaning member mounted to a support member that extends lengthwise relative to a first roller of the machine. The cleaning member has a brush having a substantial area to place against the surface of the roll. The cleaning member may be movable between an engaged position against the roll during operation, and a disengaged position spaced away from the roil in a non-operating condition, such as when replacement of the cleaning member is desired. The roll cleaning apparatus may include a drive connected to cause linear reciprocation of the cleaning member. The roll cleaning apparatus may have a drive or actuator mounted to move the cleaning member between the engaged and disengaged positions, and may be operable to bias the cleaning member against the roll in use. The roll cleaning member may have a contact head that includes an array of abrasive bristles. | 08-01-2013 |

20140238092 | Method for Producing a Crown of a Golf Club Head - A method for producing a crown of a golf club head is provided to solve the disadvantages of high manufacturing costs of conventional production of the crown. The method includes a material preparation step including preparing a sheet material to be processed, with the sheet material including a first surface and a second surface opposite to the first surface. The method further includes a formation step including press-shaping the sheet material obtained from the material preparation step at least one time by at least one mold, forming at least one rib on the first surface of the sheet material. The method further includes a milling step including milling the second surface of the sheet material obtained from the formation step, obtaining a crown for a golf club head. | 08-28-2014 |
