摘要： A four-roller type sizing mill apparatus for forming round steel rods, comprises two four-roller mills each having two pair of facing rollers. One pair of facing rollers is arranged in rolling direction perpendicular to the rolling direction of the other pair of rollers. The two four-roller mills are arranged in line, with the rolling direction of one of the two four-roller mills being shifted by 45.degree. from the rolling direction of the other four-roller mill. The two pair of rollers of a first four-roller mill positioned closer to the rolling material inlet are separated from each other by a distance which is greater than zero and not greater than five times the projected contact length of one of the pair of rollers positioned closer to the rolling material inlet. The distance is measured between a first standard straight line which passes through the centers of one of the pair of rollers and lies on a plane parallel to the side surfaces of the same pair of rollers and a second standard straight line obtained by projecting the axes of the other pair of rollers onto the above-mentioned plane.

摘要： A method of producing a steel H-sheet pile from a beam blank of an H-shape cross section, symmetrical in the vertical and lateral directions, and prepared through blooming rolling or continuous casting including a first step wherein a breakdown mill having a preparatory step forming caliber and a forming caliber is used to form the beam blank in such a manner that in the preparatory step forming caliber the beam blank is changed into an asymmetrical shape in the vertical direction and subsequently, in the forming caliber, the beam blank is rolled to have a socket and projections; a second step wherein a group of roughing universal mills is used to roll the beam blank in such a manner that in a roughing universal mill mainly the web and flanges are reduced in thickness while in a sizing universal mill the outer surfaces of the flanges are pressed by vertical slots thereof while the end portions of the flanges are sized-rolled by horizontal rolls thereof; a third step wherein a joint portion at the end portion of the flange is subjected to bending between a first roller having a projection for defining a bending position of said joint portion and a second roller having a projection for bending the joint portion and a fourth step wherein a finishing universal mill is used to finish-roll the beam blank to provide the steel H-sheet pile.
摘要翻译：一种从横截面对称的H形横截面的坯料制造钢H型片桩的方法，通过包括第一步骤的开轧或连续铸造制备，其中具有预备步骤的击穿磨机使用成形口径和成形口径来形成梁坯料，使得在准备阶段成形口径中，将坯料沿垂直方向变为不对称形状，随后在成型口径中将梁坯料卷起有一个插座和突起; 第二步，其中使用一组粗加工通用磨机来轧制梁坯料，使得在粗轧万能铣刀中，主要是幅材和凸缘的厚度减小，而在上浆通用磨机中，凸缘的外表面被按压通过其垂直槽，同时凸缘的端部的尺寸通过其水平卷筒滚动; 第三步骤，其中在凸缘的端部处的接合部分在具有用于限定所述接合部分的弯曲位置的突起之间的第一辊和具有用于弯曲接合部分的突起的第二辊之间经受弯曲;以及第四步骤其中使用精加工万能磨机来完成轧辊坯料以提供钢H型钢板桩。
