摘要： A method for manufacturing a ring-rolled product, which manufactures the ring-rolled product from a ring material, includes a step of rolling the ring material, which has an operation of rolling the ring material from both inner and outer circumferential sides thereof between a mandrel roll and a main roll in a state of rotating the ring material toward one side in a circumferential direction thereof, and induction-heating the ring material by induction heating elements. An induction heating element is disposed on only an outer circumferential side of the ring material or is disposed on each of both the inner and outer circumferential sides in a region immediately before the rolling, or an inclined portion is provided in an outer-peripheral edge portion of a coil in the induction heating element.

摘要： A wide endless-loop chain-link drilling mud separation belt formed of a plurality of laterally adjacent jointed links hinged together by transverse rods is pre-stretched prior to its installation and use on a drilling mud separation unit to prevent subsequent elongation, distortion, misalignment, chain tooth jumping, and side loading. The chain-link belt is installed on and driven in a continuous loop around a pair of parallel spaced cylindrical rollers adjustably mounted transversely in a rectangular frame of a hydraulic tensioning machine. The drive roller has a plurality of axially spaced circumferential rows of radially extending teeth that engage the openings in the links and the other roller has a smooth circumference. The drive roller and rear roller are mounted in inner front and rear tensioning frame assemblies, respectively, that are connected by hydraulic cylinders which extend and retract to move the rollers relative to one another and adjustably apply and maintain tension force in the moving chain-link belt as it is driven in a continuous loop over a period of time sufficient to achieve the desired linear expansion. In a preferred embodiment, the cylindrical rollers are formed of a metallic drum having a thick outer elastomeric layer and the teeth of the drive roller are machined into the surface of the elastomeric material to prevent metal-to-metal contact and reduce heat, wear, and friction.

摘要： The precise cutting of thin wafers from blocks or rods of hard and brittle material by means of ribbon or wire saws requires a very high strength of the sawing ribbon material or sawing wire material. In the method according to the invention, seamless metal rings are cold-rolled to form ribbon loops, optionally divided to form narrower ribbon loops or to form wire loops and optionally provided with a cutting coating. In this way, extremely strong cutting tools can be obtained.

摘要： A rolling mill for making endless bands, preferably by cold working precipitation hardenable stainless steel, includes a stationary central work roller and a pair of moveable work rollers, each carried by a corresponding carriage. The movable work rollers are backed by intermediate and drive rollers so as to be stiff in response to bending forces. The drive rollers provide rotary motion to all rollers. By elastically distorting a preform and then rolling it in the peripheral direction, the band is cold worked to a desired thickness. The preform may be obtained by parting an annular ring from tubular stock. Subsequent precipitation hardening of the cold worked band produces a stainless steel band having enhanced strength and endurance, and which is free of welds and similar discontinuities while exhibiting stress relieved edges rather than stress concentrated edges.

摘要： The specification discloses apparatus and a process for forming the female or bell end of welded wire reinforcing cages, particularly cages of the type used to reinforce concrete pipe. A cylindrical wire cage assembly is automatically centered and positioned within the apparatus and the bell end is formed by elongating one or more of the circumferential wires at one end of the cage. A force is applied between two points on the circumferential wires to simultaneously expand the wires and rotate the cage. A heat source is applied to a localized zone between the two points on the wire. The heat source and wire are moved relative to each other such that the heat zone moves along the wire as the force is applied. The wire is stretched under the force being applied to thereby continuously reduce the diameter of the wire and elongate the wire as it is moved relative to the heat source.

摘要： Various implementations include a ring material used for producing a ring molded article. The ring molded article has two convex portions which respectively protrude on opposite sides of the ring molded article in a direction of a center axis thereof and extend in a direction of a circumference of the ring molded article. A straight line passing through centers of gravity of first and second side regions is inclined by an angle relative to the center axis of the ring material, the first and second side regions are obtained by virtually dividing a one half section of the ring material based on a middle of a maximum height of the ring material in the direction of the center axis of the ring material, and a range of the angle is 7 degrees to 40 degrees.
