摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing a stepped metallic tube by which the occurrence of seizure is suppressed when cold expanding a tube. SOLUTION: A plug 10 for expanding a tube including a tapered part 20 having the surface the outside diameter of which is gradually enlarged from the top end toward the tail end and a stellitic build-up layer which is formed on the surface of the tapered part is prepared. Successively, the plug 10 is inserted into the metallic tube 50 and the tube end of the metallic tube 50 is cold expanded. After expanding the tube end, the plug 10 is pulled out of the metallic tube 50. In the cold expansion of the tube, by forming a stellite build-up layer on the surface of the plug 10, the seizure is prevented equally to the coating film of a conventional cemented carbide and by coating method.

摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a plate material for the head face of a golf club, which is made of a β-type titanium alloy material and has a hardness distribution continuously changing in a face direction, and to provide a golf club head using the plate material. SOLUTION: In a process of manufacturing the plate material for the head face of the golf club with the use of the β-type titanium alloy material, this manufacturing method comprises cold-working the β-type titanium alloy material while controlling a rolling reduction for the material so as to be different in the face direction; and then aging it. Thereby, the head face acquires the distribution of hardness in the face direction. The manufacturing method preferably further comprises solution-treating the alloy material before cold working; controlling the rolling reduction given in the cold working so as to vary in the face direction from less than 10% for the minimum value to 35% or higher for the maximum value; and carrying out the aging treatment in the range of 300°C or higher but a β transus temperature or lower, and for a treatment time of 1 to 60 minutes.

摘要： PROBLEM TO BE SOLVED: To widen a size free zone, to make the finish cross section shape about complete round even though the rolling reduction is varied and to reduce the difference of deviated diameter by mutually arranging with an inclination respective roll axes of a pair of rolling roll in a two-roll rolling mill in the inverse direction or the same direction to the advancing direction of the stock to be rolled to execute finish rolling. SOLUTION: The upstream side rolling mill Sn+1 of the last two two-roll rolling mills in a finishing mill group 6 is provided with the reduction regulating mechanism of a pair of rolling rolls 1, and the distance between the roll groove bottoms of the rolling mill Sn+1 is set so as to get closer to the objective finish diameter. The downstream side two-roll rolling mill Sn+2 is provided with the reduction regulating mechanism of a pair of the rolling rolls 1 and provided with the mechanism arranging with an inclination respective roll axes of the roll 1 to the advancing direction of the stock 2 to be rolled. Therefore, the practical size free rolling having the finish cross section shape of about the complete round, the small difference of deviated diameter and moreover the wide size free zone is executed with the two-roll rolling mill.

摘要： PROBLEM TO BE SOLVED: To provide a tube stock of excellent dimensional accuracy by keeping a taper plug in the full-float condition with one pair of four-roll stands as large diameter roll and with the other pair as small diameter rolls to dispense with the positional adjustment of the plug. SOLUTION: In a tube rolling mill in which hole type stands of four-roll type are continuously arranged, a large diameter roll bites a tube stock 4 and moves it in the axial direction. A small diameter roll 2 follows the tube stock 4 and is turned to prevent a tapered plug 3 from being pulled inside the tube stock 4 after the thickness is reduced. The tapered plug 3 is arranged on the inner surface of the tube stock 4 so that the diameter Dp of a parallel finished part meets the condition of the formula I. The small diameter roll 2 is of non- driven roll, and has the diameter of the groove bottom so that the biting angle θs of the tube stock 4 is (2β+2)-25 deg.. The tube stock 4 is cold rolled by displacing the center of rotation of the large diameter roll pair to the roll-advancing direction from the center of rotation of the small diameter roll 2 pair within the range to meet the condition of the formula II.

摘要： PURPOSE:To provide a screw performance and yield of which can be improved, and manufacture thereof. CONSTITUTION:A blade part 2 made of aluminum alloy formed with helical projections is provided on the outer circumference of a shaft 1 (coefficient of linear expansion 17X10 / deg.C) made of stainless steel (SUS304) material of diameter 20-40mm. The blade part 2 is a clad composed of two layers, an inner layer material 2a (coefficient of linear expansion 16-17.5X10 / deg.C) made of powder alloy of low hot working adaptability, and an outer layer material 2b (coefficient of linear expansion 20X10 / deg.C) made of melt alloy of high hot working adaptability. When the thickness of the inner layer material 2a is set more than 3mm, it is easy to hold the strength due to shrinkage fiting. If the inner layer material 2a occupies from the center of projection height to the outside, the possibility generating a crack at hot rolling is increased. Considering the hot working adaptability at rolling, it is favorable that the inner layer material 2a is formed so as not to appeare on the surface.

摘要： PURPOSE:To obtain the bar of dissimilar diameter in the necessary length with good accuracy by using the slanting rolling mill made by biholding the rolls in the necessary number by facing to a pass line and forming the bar of dissimilar diameter from a cylindrical blank by adjusting the distance between the roll and pass line with oil pressure. CONSTITUTION:A slanting rolling mill 20 faces three or four conical rolls 1... around a pass line and each roll shaft le... is supported by biholding it with checks 23, 24 at the inlet side and outlet side respectively. This rolling mill 20 moves the cylindrical hot blank 10 bitten between the rolls 1... in the shaft length direction with driving it by rotating around the shaft center line thereof and works the dissimilar diameter bar 11 whose outer diameter varies at the position in the shaft length direction. In case of working, the distance between each roll 1... and the pass line is adjusted via the chocks 23, 24 by the hydraulic cylinders 25, 26 fixed to a rotary and stationary housings 21, 22 respectively. The dissimilar diameter bar in the necessary length can be thus manufactured with good dimensional accuracy.
