摘要： PROBLEM TO BE SOLVED: To provide a mill for rolling bar or sections capable of replacing only a ring roll without dismantling a housing. SOLUTION: In the bar mill that disposes a plurality of roll assemblies around a pass center PC at regular intervals and is held by the housing 7, surfaces of the sides of internal diameters of a ring-fixing section 1A of a roll shaft 1 and a ring roll 2 are tapered, and the both tapered surfaces are so engaged by hydraulic pressure applied through the inside of the roll shaft from an end of the roll shaft as to be capable of being tight-fitted or separated. The end of the roll shaft at the side of a hydraulic input is disposed at the outside of the housing.

摘要： PROBLEM TO BE SOLVED: To inexpensively provide a wire rod rolling mill capable of extending the range of size-free without increasing the equipment of a rolling mill, excellent in rolling quality such as dimensional precision and suppressing in investment amount. SOLUTION: In this wire rod rolling mill A which is provided with three 4-roll mills arranged in series shifting the reducing direction 45 deg. by 45 deg. and arranged in the last of a continuous finish rolling line Ls for wire rods, among three these 4-roll mills P1, P2, P3, by taking the mill P1 for the 1st pass as an individual motor drive system with a motor M1, the range of size-free is extended. Since the mills P2, P3 for the 2nd and 3rd passes are a common motor system with one motor M2, the number of motors is reduced, the interval between the mills is narrowed, and the rolling quality is improved.

摘要： PROBLEM TO BE SOLVED: To reduce the cost needed for the housing of a roll stand and also to facilitate the handling of the housing with respect to a rolling mill for wires and steel bars. SOLUTION: This housing H of the roll stand is divided into a roll side part 4 and drive side part 5 with a parallel plane C between planes A, B. The roll side part 4 and the drive side part 5 are respectively divided into two with the plane A and the plane B. The plane A is the plane on which the axial lines of rotation of four grooved rolls 1 are present. The plane B is the plane on which the axial lines of rotation of the driving gears for respective grooved rolls 1 are present. The plane C is positioned in the vicinity of a point of contact of the pitch circle 20 of the driving gear with the pitch circle 30 of a gear to be driven and slightly on the side of the driving gear from this point of contact.

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method for a deformed wire and steel bar which is extremely high in dimensional accuracy and excellent in the out-of- roundness of the outside diameter by satisfying the fullness into the nodal grooves of a roll and simultaneously preventing excessive over-filling of longitudinal ribs. SOLUTION: Four-roll mills P1, P2 are arranged at the final two passes of a continuous finish rolling line Ls for wires and steel bars. By controlling the interstand tension between the upstream-side four-roll mill and the rolling mill Lsn just before the same in the range of 0.2-1.2 kgf/mm2, the nodes and over-filled longitudinal ribs in four places of the circumference are formed on the surface of a material to be rolled while controlling the fullness of a material into the caliber of the upstream-side four-roll mill P1 and excess and deficiency of over-filled dimensions of the ribs. By shaping by reducing the longitudinal ribs with the downstream-side four-roll mill P2, the out-of-roundness of the outside diameter is secured.

摘要： PROBLEM TO BE SOLVED: To make it possible to adjust the roll alignment by an extremely simple operation, keep the alignment adjusting value without going wrong at the time of separating a split housing, and simply conduct the readjustment after the assembly in a small man-hour. SOLUTION: This equipment comprises an exterior nut 41 fixed to a first housing 3, and interior nut 43 screwed in the exterior nut 41, and an adjusting rod 51 screwed in the interior nut 43. A first screw composed of the interior and exterior nuts 41 and 43, and a second screw composed of the interior nut 43 and the adjusting rod 51 are the double nuts, wherein the screwing direction is opposed and the screwing volume is somewhat different. The adjusting rod 51 moves forward and backward very slightly by the rotation of the interior nut 43. A roll housing is a split housing composed of the first housing 3 and a second housing, and the exterior nut 41 of an adjusting device 40 is fixed to the first housing 3 and to be left on the side of the first housing 3 when the housings are separated.

摘要： PROBLEM TO BE SOLVED: To provide a roll setting method for a four-roll rolling mill by which centering is accurately and easily set by attaching setting jigs highly accurately machinable to rolls and mutually abutting the jigs. SOLUTION: In setting the relative position of each roll of the four-roll rolling mill for rolling wires or bars by screwing down four orthogonal rolls R1 -R4 , the ring-shaped setting jigs A, B are preliminarily attached coaxially with roll axes to each roll R1 -R4 and, by screwing down each roll R1 -R4 in that state, the setting jigs A, B of the adjacent rolls are abutted. Because the setting jig A, B are highly accurately machined, the relative position of each roll is accurately set.

摘要： PURPOSE: To provide the rolling method for a bar steel small in the rate of width change and diameter difference by setting inter-stand tension between 4-roll rolling mills on a compressive side and executing continuous rolling while imparting compressive stress in the axial direction to the bar steel. CONSTITUTION: When free tension rolling is executed by use of a free tension controller(FTC), a spreading rate is changed to the negative direction and narrowing is increased as the reduction of area is increased. However, by imparting the compressive stress to the bar steel by adjusting the rotational speed of the driving motor of a 1st stand mill so as to be slightly faster than that of the 2nd stand mill, the width variation of the bar steel is increased in the spreading direction in accordance with the increase of the compressive stress. By adjusting this compressive stress to be imparted to 0.05-0.30kg/mm , the spreading change is decreased and the bar steel high in dimensional precision is obtained.
