  • Process for direct softening heat treatment of rolled wire rods
    Patent number: 4881987
    Abstract: Direct softening heat treatment of rolled wire rods comprises the steps of:providing wire rods by hot- or warm-rolling, and immediately following rolling, coiling the rolled wire rods in an annealing furnace. Apparatus therefor comprises an annealing furnace provided with an externally or internally built coiler for rolled wire rods disposed adjacent to a rolling line of said wire rods, the coiler being disposed so as to directly receive the rolled wire rods.
    Type: Grant
    Filed: January 11, 1989
    Date of Patent: November 21, 1989
    Assignee: Sumitomo Metal Industries, Ltd.

  • Method of feeding material to hot forging machine
    Patent number: 4823577
    Abstract: Disclosed is a method and apparatus for feeding a material to a hot forging machine in a forging line in which a coiled material is uncoiled, straightened, fed intermittently by pinch rollers through a heating device, cut by a cutting device and then fed into a hot forging machine. The method has the steps of preparing a driving device which drives the pinch rollers mechanically independently from the hot forging machine; picking up the timing of forging conducted by the hot forging machine as an electric signal, and controlling the driving device in accordance with the electric signal.
