摘要： A method of manufacturing a metallic tube with a spiral fin for use as a heat transfer tube of a heat exchanger and the like. A solid metallic bar or metallic elementary hollow bar provided with a small hole is supplied to an inclined rolling mill having a plurality of rolls provided with a plurality of annular grooves formed on an outer circumferential surface thereof, and the solid metallic bar or metallic elementary hollow bar is worked into a pierced hollow bar by piercing rolling by means of a piercing plug and at the same time a fin is formed on an outer circumferential surface of the pierced hollow bar to integrate the fin with a body of the tube. Accordingly, the piercing rolling and the formation of the fin on the outer circumferential surface of the tube can be carried out at the same time, so that the manufacturing process can be remarkably shortened and the productivity can be high. In addition, a high fin can be formed and the shape of the fin becomes reliable, whereby the product can be remarkably improved in quality.

摘要： A method of manufacturing hollow rods of very thick wall, in which wall thickness to outside diameter ratio is 25% or more, such as those used as work stock for manufacturing oil-well drilling collars. A cross-type or rotary mill having three or four cone-type rolls is employed without using internal sizing tools such as plug or the like, whereby a hollow work piece is worked and reduced in both outside diameter and wall thickness to the target values. In order to obtain higher dimensional accuracy and to prevent deterioration of the work material in mechanical properties, the cross angle should be positive and the feed angle should be set within the range of 3.degree..ltoreq..beta..ltoreq.20.degree..

摘要： The present invention relates to a method of manufacturing a clad bar and is basically characterized in that a columnar core member is fitted in a cylindrical outside layer member and the resulting assembly is heated, and then the heated assembly is rolled by a rotary mill provided with three or more cone type rolls to integrate the core member and the outside layer member by diffusion bending. The method is additionally characterized in that, in order to prevent unnecessary substances, such as oxides, from being formed on an interface between the core member and the outside layer member, the assembly is sealed at both ends thereof under reduced pressure or under vacuum or the assembly is cold drawn, the assembly thus welded or cold drawn is then heated and subsequently rolled by a rotary mill. Thus, an intermetallic compound layer formed between the core member and the outside layer member can be thinned, whereby improving bond strength.

摘要： The invention relates to a method of manufacturing solid metallic materials having a circular cross section by employing a rotary mill. A three or four roll cross-type rotary mill is employed, with cross and feed angle setting selected so as to meet specific conditions. The method permits efficient production of metallic materials without internal cracks or internal fracture initiated from porosity. In one version of the method the material being worked is rotated. In another version the material is not rotated and the roll housing is rotated around the former. Where the latter version is employed, it is possible to work the material as produced by a continuous casting machine and without cutting.

摘要： An exemplary embodiment of the invention provides a method for producing an ultra thin wall metallic tube by cold working method with significant wall thickness reduction. In a method for producing the metallic tube with a cold pilger mill according to the invention, cold rolling is performed while tube diameters are being expanded using rolls having tapered groove dies whose calibers increase from an engaging entry side toward a finishing exit side. In a method for producing the metallic tube with a drawing machine according to the invention, cold drawing is performed while the tube diameters are being expanded using a solid die whose calibers increase from an engaging entry side toward a finishing exit side and a plug of a tapered mandrel bar whose diameters increase from an entry side of the die toward an exit side. In the metallic tube producing method, a maximum diameter of the plug or tapered mandrel bar may be larger than an outside diameter of the mother tube.
