摘要： In a mold for casting a billet with a curved type continuous casting apparatus, D0 (m) is an inner diameter at a lower mold edge and R0 (m) is a curvature radius of an outer curvature side at the lower mold edge. When a rate of change Tp (%/m) in mold inner diameter per unit length along a casting direction is Tp=(1/D0)×(dD/dx)×100 (%/m), and when a rate of change Rp (%/m) in curvature radius of an outer curvature side per unit length along the casting direction is Rp=(1/R0)×(dR/dx)×100 (%/m), the rate of change Tp in mold inner diameter and the rate of change Rp in curvature radius satisfy a relationship expressed Rp=(Tp/2)×(D0/R0), where D is a mold inner diameter at a distance x away from an upper mold edge and R in Formula 2 is a curvature radius of the outer curvature side at the distance x.

摘要： Twin-roll caster for continuously casting metal strip comprises a pair of parallel casting rolls (1) each provided with longitudinal cooling water passages (26) adjacent other casting surfaces 25 of the rolls. Passages (26) are interconnected in groups of three to form three pass zig-zag water flow channels for flow of water back and forth between the roll ends. The roll ends are notched to form outwardly facing shoulders (44) for engagement with casting pool confining plates (10). Cooling water flows to and from the passages (26) through radial passages (35, 36) in roll end walls (27, 28) in the vicinity of the shoulders (44).

摘要： A chimney has a lower portion substantially in the shape of a pyramid and an upper portion forming a cylindrical portion that extends with a predetermined dimension upwardly and is provided in a ceiling portion of a building of a coil yard that is used for temporary storage of the hot-rolled coil which is an intermediate iron and steel product acting as a high-temperature heat radiator that is manufactured using the hot-rolling equipment of an iron and steel mill. A power generating turbine is provided at a predetermined position in the cylindrical portion. An intake duct is provided on a lower end portion of the side walls of the building. Hot-rolled coils that are in a high-temperature condition after manufacture are successively imported into the coil yard and accumulated and stored until transfer to a subsequent processing step. An ascending airflow is generated by sequential heating of air introduced into the building from the intake duct using heat retained in the hot-rolled coils. The power generating turbines are rotated by the ascending airflow passing through the cylindrical portion of the chimney to thereby execute wind power generation. As a result, the heat retained in the high-temperature heat radiator manufactured by introduction of heat can be efficiently used.

摘要： A method for continuously casting a billet with a small cross section in which a curved type or vertical type continuous casting machine is used while oscillating the mold upward and downward is characterized in that the casting machine is provided with a mechanism for withdrawing speed oscillation. The mechanism has structural play in the directions of driving and reverse driving in such a manner that the amount of a play-incurred displacement from the neutral position of the structural play in the direction of billet driving or reverse driving is ±2 to ±30 mm in the direction of driving on the pinch roll circumferential length equivalent basis. The mechanism produces a returning force toward the neutral position and operational parameters such as the billet length, the specific amount of secondary cooling water, the casting speed as well as the oscillation amplitude and frequency are optimized.

摘要： A reduction gear transmission capable of realizing a large reduction ratio while preventing both an increase in its diameter and a decrease in the diameter of its through hole, including: a motor gear; an intermediate shaft; a first and second gear; an input shaft; and an external and internal gear. The first and second gears are fixed to the intermediate shaft. The first gear meshes with the motor gear. The input shaft causes an eccentric rotation member to rotate eccentrically with the rotation of the input gear, which meshes with the second gear. The external gear engages the eccentric rotation member, revolving orbitally around an axis line of the input shaft. The internal gear meshes with the external gear, each having a different number of teeth. The motor gear and first gear mesh at a position offset from a straight line formed by connecting an axis line of the intermediate shaft and of the input shaft.

摘要： The invention addresses the problem of edge bulging and breakout of as cast strip due to a decrease of perfect solid phase shell thickness of the strip caused by heat recuperation of the unsolidified portion of the strip, by providing a chamber 19 which encloses the travel path of a strip 8 delivered from a pair of chilled rolls 1a and 1b, a pair of chilled blocks 29a arranged in the chamber to be positioned near a nip between the chilled rolls 1a and 1b, with each chilled block 29a being shaped for loose fitting over an edge of a strip 8 and being capable of injecting cooling gas toward the edge of the strip 8.
