摘要： In the cold rolling process by pilger rolling that holds a mandrel between each of paired roll-dies, by optimizing the side relief rate SR and the mandrel factors like the taper θ1 in the primary deformation zone of the mandrel and the taper θ2 in the final size reduction zone thereof, and the feed rate F of the workpiece material, and at the same time by properly adjusting the relationship between the side relief rate SR and the feed rate F, the dimension-related shape characteristics (near-perfect round shape) of the tube inside surface after the final finishing rolling process by pilger rolling can be ascertained to thereby ensure excellent surface property without requiring a new apparatus, and further without causing the decrease of the product yield and/or the increase of the manufacturing costs. Thus, this can be widely applied for producing steam generator tubes which exhibits high S/N ratio in the inner coil eddy current testing.

摘要： The present invention provides a seamless tube piercing/rolling plug and a seamless tube producing method in which piercing/rolling is performed with an inclined rotary piercing mill while the seamless tube piercing/rolling plug is used as a piercing tool. The seamless tube piercing/rolling plug is used while a front part and a rear part of the split plug are held as an integral plug, at least the front part is made of low alloy steel, and oxide films are formed on surfaces of the front part and rear part. The present invention also provides a seamless tube piercing/rolling apparatus and a seamless tube producing method in which the front part and/or rear part is replaceable in a tube making process line using the seamless tube piercing/rolling apparatus. In the seamless tube piercing/rolling apparatus, the front part and rear part are held as the integral plug, the front part and/or rear part is removably mounted, a mandrel bar holding the plug goes through the rear part, and the mandrel bar is coupled with the front part. It is preferable that a thickness of the oxide film formed in the front part be set to 200 µm or more while the oxide film formed in the front part is thicker than the oxide film formed in the rear part. Even if a hard working material is pierced/rolled, a seam defect and inside surface defects are eliminated, and excellent life-time of plug and excellent plug cost per production quantity can be achieved.

摘要： A reducing mill according to the invention includes a plurality of stands disposed along a rolling direction line, in which a tube is rolled through the plurality of stands along the rolling direction line. The stands each include n rolls (n≥3) disposed around the rolling direction line, and the n rolls are disposed shifted by 180°/n around the rolling direction line from n rolls included in a preceding stand. The n rolls included in each of the plurality of stands excluding the last stand each have a groove having an arch shape in cross section. The bottom of the groove has a circular arc shape around the rolling direction line having a first radius in cross section, and the distance between the surface of a roll flange portion positioned between the bottom and the edge of the groove and the rolling direction line is longer than the first radius, and the distance between the edge of the groove and the rolling direction line is longer than the first radius in the groove of a roll included in the preceding stand. Therefore, the reducing mill according to the invention allows both polygon formation and roll edge marks to be suppressed.

摘要： While a reference means having a positional relationship to the pass-line of a continuance mill determined in advance and caliber profile (area enclosed by the groove profile of a rolling roll) formed by a rolling roll at each stand are imaged within the same visual field and a position corresponding to the pass-line is calculated based on the region corresponding to the reference means within the taken image, the center position of the region corresponding to the caliber profile within the taken image is calculated and the misalignment amount of the caliber profile can be calculated based on the calculated center position and the calculated position corresponding to the pass-line. Accordingly, a misalignment amount can be measured accurately as long as images of the reference means and the caliber profile are taken within the same visual field.

摘要： The invention concerns the control of male or female taper pipe threads (3) located at the ends of metal tubes for sealed assembly thereof. The method consists in controlling the pitch diameter of threads in a measuring plane (P1) substantially located in the middle of zone containing perfect threads using a planar diameter-measuring apparatus (51) whereas the pitch diameter of threads is conventionally measured by the specification API 5B in the plane (P0) of the last perfect male thread and in comparing the measured pitch diameter of the threads with an estimated value (D1e) calculated from the pitch diameter nominal value in the plane P0, from the distance the distance between P0 and P1 and from a transfer value of the taper, itself a function of the distribution of the taper ratios produced. The invention enables to better estimate the thread interference in the proximity of sealing surfaces (5, 6) and/or bearing surfaces (7, 8), hence the sealing capacity of the assembly.
