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： In a heat transfer tube for a steam generator, a surface roughness of an inner surface of the tube is measured along a longitudinal direction and an amount of dimensional variation in a length of 50 mm taken from a measured roughness chart is 4 μm or less and an amount of bend crookedness in a portion of a length of 1000 mm from a tube end is 1 mm or less. Hence, when the tube is produced, an inspection of the tube by an eddy current flaw detection can be conducted at a high S/N ratio and hence an inspection efficiency can be improved, and when the tube is assembled into a heat exchanger, the assembling operation can be easily performed.

摘要： A method of and an apparatus for rolling a rod as a starting material and producing a wire of 5 mm or smaller diameter, the method and apparatus using a continuous rolling mill comprising a plurality of round-grooved four-roll stands arranged in tandem, wherein the grooved four-roll is displaced between adjacent rolling stands by 45 degrees relative to each other around the pass line and the center-to-center distance between adjacent rolling stands measured in the pass line direction is not greater than 50 times the diameter of the rod. The front end portion of the rod is fed at slow speed into the continuous rolling mill, the front end portion being guided by a front pipe to the center of the round groove, and the front end portion is wound on a coiler. After that, the rotation speed of the grooved rolls in each rolling stand is so set as to prevent slack in the rod passing through the continuous rolling mill, and the rod is rolled at high speed, without causing the rod to touch the leading pipe, to produce a wire. Each of the rolling stands that constitute the continuous rolling mill is movable in a direction perpendicular to the pass line, each rolling stand being moved for connection to or disconnection from the driving source.
