Abstract: A method for cooling and lubricating rolls and/or the rolled material in cold rolling of metal strips in a rolling mill stand. The method includes supplying emulsifiers as necessary and emulsions which contain at least one oil phase. The emulsion is prepared immediately in front of the rolls of the rolling mill stand or immediately in front of the strip inlet into the rolling gap formed by the work rolls by separately supplying the media which form the emulsion.

Abstract: The invention includes apparatus and method for lubricating and cooling a workpiece, dies or ironing rings, and punch at the interface between the workpiece and such dies or ironing rings and punch in forming a workpiece into a hollow closed end cylindrical article.A lubricant liquid phase is injected into a coolant liquid phase to form a "dispersion" prior to application to the metal-tool interface. Providing the lubricant as a dispersion in the coolant liquid phase rather than as an emulsion provides several advantages. The quantity of lubricant and the time of lubricant injection can be varied to control lubricity and, thus, friction. The invention makes it possible to achieve differential friction in the ironing process by having higher lubricity on the ironing die (low friction) and lower lubricity on the punch surface (high friction). Lubricities and cooling are controllable for the specific metal forming process employed to produce closed end hollow body containers.

Abstract: Hollow billet (13) in a first operation of a piercing mill (1, 2) is advanced over a piercer (10) placed on front end (5) of a piercer rod (6) and is retracted after removal of the piercer. During the advance of hollow billet (13) a lubricant is applied to the hollow billet inside wall processed immediately before by piercer (10) with the help of an inert carrier gas current through outlet openings (16, 17) on front part (14) of piercer rod (6). In this way the lubricant is distributed uniformly on the hollow billet wall in the first operation for processing in the second operation of the piercing mill and in the latter for processing in a third operation (in a reeling mill). Thus, no delay whatsoever occurs in the processing, i.e., the operations can be performed without interruption successively, and no environmental pollution by the agent occurs.

Abstract: The invention relates to a method and apparatus for open-die forging of workpieces in forging presses at high forging temperatures, more particularly steel billets or ferrous alloy billets between about 800 and 1250 degrees Celsius. In conventional open-die forging it is often not possible to complete the forging process in a single heat, and the workpiece must therefore be reheated. Also, with direct contact between workpiece and tool, cracks occur, particularly in the vicinity of bulges, the prevention or straightening of which requires repeated transverse hammer- or pressure-forging, so lengthening the cooling time. The total energy consumption for deformation and heating of the workpieces is therefore relatively high.

Abstract: A substantial amount of liquid lubricant used in a cold strip rolling mill is prevented from passing between the area of the work roll necks and work roll bodies not in contact with a strip by locating in a strip guiding means on the entry side adjacent both edges of the strip, several zoned air nozzles which delivery a positive pressure to force the liquid away from this area, in a direction toward the center of the strip and rolls, and which nozzles are controlled according to the width of strip being rolled. The relatively small amount of liquid finding its way onto the delivery side is removed from the strip by providing in the strip guiding means both positive and negative air pressure means located above and below the strip, and negatively pressurized longitudinal enclosures located adjacent both edges of the strip and the said area.

Roll lubricant is directed by nozzles 80 on to the work rolls (12, 13) and the work (16) outside the confines of the casings.

Abstract: A plug for use in the plug drawing of hollow tubes or other stock. A flexible and deformable seal is mounted on the rearward part of the plug.

In its deformed state, which it is caused to adopt in use, it effectively seals the rearward end of a cylindrical clearance between the plug and the stock, so enabling this clearance to be filled with pressurized lubricant to improve drawing efficiency. The lubricant is supplied through passages formed in the plug and connected to a hollow conduit extending backwards within the undrawn stock. The conduit may be flexible, or may be rigid and then act as a plug bar. The plug may be in two parts which are caused, as drawing begins, to move relative to each other and in so doing to deform the seal.
