摘要： Disclosed is a walking beam and more particularly its driving mechanisms whereby a material placed on a plurality of stationary beams for transfer, e.g., a steel product such as a steel pipe or round bar is raised from below, moved forward and lowered again onto the stationary beams by a plurality of transfer beams and this process is repeated to effect the transfer of the material. Each of the driving mechanisms includes a first link for causing the transfer beam to make a circular motion and the first link is rotatable about a supporting shaft with a radius of rotation l. The supporting shaft is fitted in the forward end of a second link and is rotatable about a main rotating shaft with a radius of rotation 2l. Mounted also on the supporting shaft is a first gear which is rotatable along with the first link and the first gear is in mesh with a second gear mounted on the main rotating shaft. The driving of the second gear and the second link is controlled selectively such that one of them is driven and the other is locked or both of them are driven and in this way the feed length of the transfer stroke of the transfer beam is changed to 2l, 4l or 6l.

摘要： Disclosed is a high-efficiency manufacturing installation in which seamless steel pipe rolling and finishing lines are matched in capacity with each other and are formed into a single continuous lines.The high-speed rolling line extends to a straightening machine via a cooling equipment for as-rolled pipes and a heat treating equipment for pipes to be heat-treated and is further connected to a single-line finishing line via a nondestructive inspection machine and a cutting machine. The finishing line comprises each plurality of different finishing machines arranged along a variable feed pitch transverse transfer line, the plural number being selected in correspondence to the capacity of the rolling line. The cooling equipment and the heat treating equipment are designed so that each of them requires the same transfer time and thus there is no danger of causing any blank in the feed pitch spacing during the change-over between the as-rolled pipes and the pipes to be heat-treated.

摘要： A roll changing apparatus for rolling mills which is adapted for use in the manufacture of seamless steel pipes. The apparatus comprises a pair of sliding bases each mounted on a base block and movable parallel to each other, a plurality of roll carriages each containing a set of rolls, and means for moving the roll carriages, wherein two or more of the roll carriages are placed on each of the sliding bases and at least one of the roll carriages on each sliding base is moved forward to form a roll mill. When the roll carriages are to be changed, the forwardly moved roll carriages are moved back onto the sliding bases and then the other roll carriages are moved forward, thus automatically accomplishing the roll carriage changing in a short period of time.
