20090266128 | APPARATUS FOR ROTATING A CONTAINER BODY - An apparatus for rotating a container body that utilizes frictional forces rather than the engagement of gears to rotate the container body is provided. Such an apparatus may include a stationary housing and a turret rotating on a shaft proximate to the housing. The turret may have a plurality of pockets and a roller assembly disposed within each pocket. Each roller assembly may have a body portion and a drive roller portion. Each body portion may have a contact portion for contacting a container body received in a respective pocket. Each drive roller may be in contact with the housing such that as the turret rotates, friction between the drive rollers and the housing causes each roller assembly to rotate. | 10-29-2009 |
20120304721 | COLD-ROLLING METHOD FOR PREVENTING FRACTURE OF HIGH-SILICON STRIP STEEL - A cold-rolling method for preventing fracture of high-silicon strip steel, characterized in that the high-silicon strip steel has a Si content ≧2.3 wt %, and at the beginning of cold-rolling, the temperature of inlet strip steel is above 45° C.; during the cold-rolling process, an emulsion liquid is sputtered to the strip steel, a flow rate of the emulsion liquid is 3500 L/min at the inlet in rolling direction, a flow rate of the emulsion liquid is 1500-4000 L/min at an outlet in the rolling direction, and the temperature of the strip steel is maintained above 45° C. under the precondition to guarantee technological lubrication. The cold-rolling method of the invention might prevent fracture of a head portion and a tail portion of the strip steel, raise the rate of finished products, and increase production efficiency. | 12-06-2012 |

20110197643 | Heat Exchanger Fin Stock Lubrication System - Embodiments according to this disclosure include methods and systems for lubricating sheet metal stock by wiping a controlled amount of lubricant onto the surfaces of the sheet metal with strips of material, such as felt, saturated with the lubricant. The lubrication methods and systems disclosed herein can also provide for control of the pressure at which the lubricant is delivered, the volume of lubricant delivered, and the frequency lubricant is delivered to the felt strips. The lubricant is delivered to the felt strips at a number of locations and the felt material is configured to naturally wick the lubricant from the injection sites to the spaces between injection sites to substantially saturate the entire strip. | 08-18-2011 |
20130192326 | METHOD FOR DRAWING METALLIC TUBE - In a method for drawing a tube blank while supplying lubricant to an inner surface of the tube blank from a discharge opening of a rod, the lubricant is adhered appropriately to the inner surface both in the circumferential direction of the tube blank and in the longitudinal direction thereof without using any application member such as a core. While drawing a metal tube blank | 08-01-2013 |
20140260476 | MANUFACTURING METHODS AND APPARATUS FOR TARGETED LUBRICATION IN HOT METAL ROLLING - Rolling mill apparatus and methods of hot rolling with targeted lubrication are provided herein. A rolling mill apparatus having multiple roll stacks may include a cooling fluid pump and a lubricant pump fluidly coupled with cooling nozzles and lubrication nozzles through a piping system. The piping system may be configured such that the lubricant pump introduces neat lubricant that mixes with the cooling fluid to form a lubricating fluid as loose lubricant emulsion for discharge to select roll stacks through one or more lubrication nozzles, while one or more cooling nozzles discharge the cooling fluid without the added lubricant. The lubrication nozzles may be aimed to target discharge of the lubricant emulsion to the bite roll. Modifications to mill headers to provide targeted lubrication in accordance with the invention are also provided. | 09-18-2014 |
