Abstract

DC60 (05/11/45) This invention is a method for cold rolling of materials such as stainless steel and / or non-ferrous metals in a rolling process with a A lot The first one, one (multiple) platen works to greatly reduce the size, and one final press (several) determines the surface quality of the tabs. There is a relatively small reduction in size in the adjustment of the extrusion process, in terms of thickness reduction and in the surface quality of the body. The bar that has been rolled out This invention provides a method in which the extrusion is passed on one flight of the body. The strips are rolled through a relatively large reduction in size and an emulsion is used as a refrigerant. And lubricant. Subsequently, the refrigerant and the adhesion lubricant film are rolled. Coming out of the strip after it comes out of the extrusion channel in the final emulsion extrusion platform, the extrusion oil is specifically used as a lubricant in the final rolling (lump) through the rolling process Which will have a relatively small reduction in size Devices in use of this method are also disclosed. Figure 1 This invention is a method used to cold-roll strips of material such as stainless steel. And / or non-ferrous metals in Ironing process with a large number of rolling stands One of the first (many) presses works to significantly reduce the size and One last stand (several) will be the designated platform. Surface quality of the bar There is relatively little reduction in size in the modifications of the extrusion process in terms of thickness reduction and In terms of the quality of the skin of the body The rolled strips then provide a method in which the extrusion passes in First trip of the body The strips are rolled through the sizing will be reduced. Quite a lot and emulsions are used as a refrigerant And lubricant. After that, the refrigerant and the film that As the adhesion lubricant will be rolled Coming out of the bar After the strip comes out of the extrusion channel in the final emulsion extruder, the extrusion fluid is used exclusively as an additive. Lubricated in one last pass (multiple passes) through a rolling process, where there is a relatively small reduction in size. Devices in use following this method are also disclosed in Figure 1.

1. Methods for cold rolling of strips of material such as stainless steel and / or Non-ferrous metal Ironing process using a rolling pin The first, one (multiple) platen is a relatively reduced size, and one (several) the last one determines the surface quality. Of the bar, which will have The downsizing is relatively small. Where directed by the manner Emulsions are used as a refrigerant and lubricant in Rolling through the first round of the body The strip is rolled through a rolling process where the size is reduced somewhat and the refrigerant and the film-bonded lubricant are extruded from the strip body after the strip. This comes out of the rolled compartment and the oil. That is used to iron will be taken Use exclusively As a lubricant for rolling in the end One end (multiple) of the rolled strip body At this stage, there will be a relatively small reduction in size. 2. Method as stated in Clause 1, which is directed by the manner in which Emulsions are first used as a refrigerant in One last pallet (several) for passing through.
