摘要： PROBLEM TO BE SOLVED: To manufacture a product having good quality without causing defects of dimension and shape even when carrying out formation of extensive web heights from the case of having no increase in a web height to the case of performing expansion of the web height exceeding 50 mm through a pair of roll sets. SOLUTION: An oblique roll type rolling mill is arranged for rolling between an intermediate rolling process and a finish rolling process of a shape steel rolling process including a rough rolling process, the intermediate rolling process, and the finish rolling process. In a method of rolling a shape steel having a flange of a series having a web height not less than 600 mm which performs the expansion of the web height while rolling down an excessive metal part at both sides of a web of a material to be rolled, when a roll axis of an oblique roll is projected to a horizontal surface in parallel with a rolling direction and an angle made between the projected roll axis and a surface perpendicular to the rolling direction is made to θh, and the roll axis of the oblique roll is projected to the surface perpendicular to the rolling direction and an angle made between the projected roll axis and the surface in parallel with the rolling direction is made to θv, rolling is carried out by setting the relation between θh and θv to be θh COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a rolling method by which an asymmetrical wide flange rough shape billet which is free from bend can be manufactured efficiently and at high yield.
SOLUTION: In the method of rolling the asymmetrical wide flange rough shape billet, an asymmetrical dog-bone-shaped billet 10, 20, 30 is formed by reducing a width of flat rectangular billet 50 by edging calibers G1-G3 by making the bottom diameters of the edging calibers G1-G3 into different diameters and independently driving upper and lower rolls 11, 12 so that the upper and lower bottom circumferential speed of the edging calibers G1-G3 are approximately equal (first stage). Next, the asymmetrical wide flange rough billet 40 is formed by repeatedly reducing the dog-bone-shaped billet 30 in the thickness direction by using a forming caliber G4 (Second stage). On the way of this second stage, by making upper and lower rolls 11, 12 independently drive so that the upper and lower circumferential speed of the edging caliber G3 is different and edging the material 35 to be rolled on the way of rolling or after rolling with the forming caliber G4 by using the edging caliber G3, the bend of the material 35 to be rolled is straightened.

摘要： PROBLEM TO BE SOLVED: To provide a rolled steel sheet pile excellent in joint strength and productivity.
SOLUTION: In this rolled steel sheet pile (1), fitting joints 5 of the same shape each are formed at the terminal ends of end flanges 3, which are located on the both sides of the pile (1), in such a manner as to be mutually symmetric with respect to a point. The pile (1) is formed in such a manner that the central axes of the fitting joints 5 at the coupling of the piles (1) almost correspond to the axes of the flanges 3 located on both the sides of the pile (1). A tapered fitting groove with an approximately trapezoidal cross section is formed in the fitting joint 5 by using a bent pawl part; a tip locking part is formed at the tip of the pawl part; and the fitting groove and the tip locking part are fitted together so that the adjacent piles (1) can be coupled together.

摘要： PROBLEM TO BE SOLVED: To prolong the life of a rolling roll by applying a specified web thickness draft to a flange width draft at the same time at the time of edge rolling. SOLUTION: When edge rolling is executed, a building part is generated at an edge part. A roll part brought into contact with the bulging part is worn locally. By making the bulging amount small, the local wear of the roll can be prevented. Simultaneously with edge rolling of the flange, the web is rolled, owing the drawing function, the tension of the longitudinal direction is applied on the flange part and the local bulging amount is made small. A back-up roll 63 is pressed freely rotating on the external circumference of a shaft part 62 of the web rolling roll 61. A flange reduction work roll 64 is supported by the back-up roll 63. The work roll 64 is displaced in the direction shown by an arrow mark A by opening or closing the back-up roll 63, and the rolling reduction is regulated. Simultaneously executing edge rolling with the work roll 64, the web part is rolled with the web rolling roll 61, and the bulging amount is made small.

摘要： PURPOSE:To reduce uneven friction on the side of horizontal rolls and to prolong the life of the rolls by lubricating the upper and lower face of the web of a rolling stock or the reduction face of the web of a pair of upper and lower horizontal rolls in a universal rolling mill and also nonlubricating the sides of a pair of upper and lower horizontal rolls. CONSTITUTION:A nozzle is arranged in a position symmetrical in up and down and left and right proximately to the web reduction faces 4-2, 5-2 of horizontal rolls 4, 5, in the entrance side for rolling; and a lubricant is injected from this nozzle to the web reduction faces 4-2, 5-2 of the horizontal rolls 4, 5. A nozzle is also arranged in a position symmetrical in up and down and left and right proximately to the upper and lower web faces of a rolling stock ; and the lubricant is injected from this nozzle to the upper and lower web faces. A friction coefficient is reduced between the web face of the rolling stock and the web reduction face 4-2, 5-2 of the horizontal roll; and on the contrary, the side faces of the horizontal rolls are nonlubricated so as not to lower the friction coefficient. Thus, an uneven friction is reduced by a simple means on the side of a horizontal roll affecting the life of the roll, and the long life of a roll is attained.

摘要： PURPOSE:To suppress the generation of insufficient thickness and recessed part in flanges and to enable manufacturing large wide flange shapes by rolling the web of a rough shape billet while producing the metal flow from the web to flanges. CONSTITUTION:In a 1st roughing universal mill 2a, the web reducing parts 24 and the corner parts 25 of upper and lower horizontal rolls 22 are constituted of one, plural circular-arcs or the conbination of a circular-arc and a straight line. When these horizontal rolls 22 are used, rolling reduction in the thick parts at both ends of web in the initial pass is reduced and also, at the time of reducing of the web, components of force toward flange sides are exerted from the surfaces of the horizontal rolls, so metal flows to the flanges easily and an intermediate billet 56 having thicker thickness in the flanges is obtained. The web thickness in both end parts of web of the intermediate billet 56 is thicker than that in the middle part of web. In this way, the large sizes of an extremely thick wide flange shape and large wide flange shape which are difficult to ensure the thickness of flange are manufactured without generating defects in the dimensional shape and surface property.

摘要： PURPOSE:To roll a large H-beam by forming a flange generating pass to plural passes, in which width of each pass are about equal and height of center projecting parts are different, and alternately executing edge rolling with the flange generating pass after a V shape groove is imparted to the short side of a rectangular cross section with the pass. CONSTITUTION:When the width direction center part of a flange is divided by the center bulged part 221a under a first flange generating pass G2-1, the neighboring metal is displaced in flange width direction, both ends thereof are restricted by the side wall 321 of a pass, thus, there is no increase in the flange width but the thickness is increased. Further, a gage mark S is moved in the arrow direction, an amount of which is infestimal. Successively, the stock to be rolled is introduced into a second flange generating pass G2-2, by a groove of the pass, the part excepting the recessed part of flange center part of the stock to be rolled is pressed. By this method, a distance between the flange outside face and gage mark is decreased from I1, to I2, the metal around the gage mark S is flowed in flange direction so as to increase the flange cross sectional area.
