摘要： A process for producing a thin-webbed H-beam steel having a web thinner than flanges, which comprises the steps of: forcibly water cooling the outer surface of the flanges during an intermediate hot rolling prior to a final hot rolling, so that the flange outer surfaces are cooled to a temperature of 700 DEG C or lower; terminating the forcible water cooling during the intermediate hot rolling so that the flange outer surfaces are returned to a temperature higher than 700 DEG C; repeating the forcible water cooling and the termination thereof during the intermediate hot rolling to refine the microstructure of the flange surface to a predetermined depth from the surface; final-hot rolling the intermediate-hot rolled H-beam steel; and forcibly water cooling the flanges of the final-hot rolled H-beam steel immediately after the completion of the hot rolling, in a manner such that either the cooling time is not longer than an upper limit or the difference between the flange and the web temperatures upon completion of the cooling is not less than a lower limit, within which upper and lower limits the wavy web does not occur during the cooling, and such that either the cooling time is not less than a lower limit or the difference between the flange and the web temperatures upon completion of the cooling is not more than an upper limit, within which lower and upper limits a thermal stress, generated in the web during air cooling to room temperature, does not exceed a buckling strength of the web, the upper and lower limits being predetermined with respect to the size of H-beam and the density of the coolant water quantity. An apparatus for carrying out the process is also disclosed.

摘要： PROBLEM TO BE SOLVED: To precisely manufacture even shapes asymmetry between flanges on the drive side and on the working side by independently controlling a roll interval between horizontal rolls and vertical rolls on the drive side, and a roll interval between the horizontal rolls and the vertical rolls on the working side. SOLUTION: After a material is bit by a universal rolling mill, the rolling loads of the vertical rolls 2DS on the drive side and the vertical rolls 2ws on the working side, are measured by load cells 3DS and 3WS. Measured results are memorized in an arithmetic unit 4 as lock-on values. After that, the rolling loads of the vertical rolls 2DS on the drive side and the vertical rolls 2WS on the working side, are continuously measured, measured results are inputted in the arithmetic unit 4. With respect to both vertical rolls 2DS and 2WS. differences to the lock-on values, that is, rolling load deviations are found. By finding roll interval control quantities of the horizontal roll 1 and the vertical rolls 2DS, 2WS, by a prescribed formula, using the arithmetic unit 4, control is performed by drawing down controllers 5DS and 5WS Consequently, even the shapes with the nonsymmetry flanges can be precisely manufactured.

摘要： PURPOSE:To allow the manufacture of H shape whose ratio of the flange to the wed is large, i.e., H shape of excellent sectional performance by utilizing the trucking information of steel material, operating the cooling zone sequentially and successively jetting the cooling liquid. CONSTITUTION:When the material to be rolled is rolled to (13) direction, the surface temperature of the material to be rolled is measured with both flange thermometers 7a, 7b before the flange cooling device having two zones 9, 10 of the inlet sides of the universal mill U and the edger mill E and the wed thermometer 8, based on the difference of the temperature of the wed and the flange of the material to be rolled, whether there is or not the forcible cooling for the zones from 9 to 12 of flange cooling devices including two zones 11, 12 after U and E rolling is decided with the calculation with the calculator or with reading the table preliminarily inputted. By storing the position of the material to be rolled decided whether there is or not the forcible cooling for the zone based on the temperature difference in the calculator, the position of the material to be rolled is passed through the zone based on the trucking information of the material to be rolled, the cooling liquid is controlled to jet or not according to the instruction.

摘要： PURPOSE:To eliminate the movements of side guides and to make the entrance and exit of a rolling material smooth by making a housing that incorporates caliber rolls movable in the axial direction of the roll and in the vertical direction, in a caliber rolling mechanism. CONSTITUTION:Tables 3, 5 formerly movable are made stationary, and side guide rails 4, 6 are also fixed at prescribed positions separated by a prescribed distance. A housing 10 with caliber rolls 1, 2 is mounted on a sole plate 11 and is made movable in the axial direction of the roll axis by a cylinder 13. Further, the housing 10 is made vertically movable by a cylinder 12 on the plate 11 to fit the calibers of the rolls 1, 2 to a prescribed position. A rolling material M goes smoothly in and out of the caliber without being bent laterally or vertically. The dimensions and cross-sectional shapes at both ends of a formed shape- steel M are made uniform and highly accurate to improve its quality.

摘要： PROBLEM TO BE SOLVED: To remove a play in the axial direction of a horizontal roll and to improve dimentional precision of products and productivity by providing a hydraulic cylinder to receive a rolling reaction force in the axial direction, a sensor for measuring shifting amount of a cylinder rod, and hydraulic pressure controlling equipment on a horizontal roll to roll a shape with different figures in right and left flanges. SOLUTION: Initial plays of a shaft from which a play is to be removed is specified as a1 , a2 , b1 , b2 (a1 >a2 ). When a left side vertical roll 2a is shifted in the rightward direction while being pressed on a horizontal roll, a lower horizontal roll 1b arrives earlier at a set pressure Pr2 of a hydraulic cylinder 21b, and at this time, a2 =O and on this condition removal of play is completed. An upper horizontal roll 1a is at an pressure of a hydraulic cylinder 21a, Pr

摘要： PROBLEM TO BE SOLVED: To improve the conveyance position accuracy of rail members in a longitudinal conveying line of erect rail members. SOLUTION: On the downstream side of opposed linear guides 11 that nay be freely set to gradually narrow the passage width of rail members along the longitudinal conveying direction of erect rail members, at least one of roller guides 1a to 1h is placed, which each comprise opposed rollers with a mechanism that allows their position setting right across the conveying direction and also their reciprocating motion of a short stroke. For severer position accuracy, on the downstream side of the linear guides 11, at least one of guide rollers 2a to 2f is also placed, which each comprise a roller that gives a press to three portions of a rail member, or both the chamfered portions from the vertex down to the head side and the sole, in the perpendicular plane to the conveying direction.
