  • Patent number: 6187118
    Abstract: A method of heat-treating a work piece of high-alloy steel by hardening involves relatively briefly annealing the work piece before hardening, followed by cooling the work piece. The brief annealing that is performed before the actual hardening and the ensuing cooling results in homogeneity of the material in the microscopic range. Following the annealing, the work piece is hardened, for instance by quenching in a salt bath, to achieve a super fine distribution of globular carbides in the microscopic structure with considerably reduced size as compared to the outset state. Also, the microscopic structure created by the method of the invention has improved toughness properties as well as increased microscopic structure stability to aging and leads to a longer service life.

  • Patent number: 6174390
    Abstract: A spiral parts heat treatment apparatus includes a first guide, a transfer unit, a second guide, and a controller. The first guide has a carrier portion that continuously conveys the manufactured spiral parts carried thereon in a longitudinal direction. The transfer unit is disposed downstream from the first guide to feed the spiral parts one by one after discrimination. The second guide is provided continuously to the transfer unit and has a carrier portion and a driving portion. The carrier portion serves to guide the spiral parts carried thereon in the longitudinal direction in the heat treatment furnace. The driving portion serves to push the spiral parts from a rear end side thereof and a driving portion. The controller performs a control operation so as to feed the spiral parts one by one.

  • Patent number: 5958158
    Abstract: The invention relates to a process for producing hot-worked elongated products, such as bars or tubes, from high-alloy or hypereutectoid steel in which a feedstock is heated to a deformation temperature and undergoes at least one deformation step. Following the at least one deformation step, the deformed feedstock is either cooled or heated at a specific temperature to achieve a uniform temperature distribution throughout the length and thickness of the deformed feedstock. Next the deformed feedstock is reheated to a temperature below the deformation temperature. The reheated feedstock is continuously rolled in a multi-stand reducing mill to its final size and then cooled by ambient air.

  • Patent number: 5785760
    Abstract: A self propelled, walk-behind or surrey drawn striping machine includes a single fluid tank for confining and, delivering under a pressure, fluid drive, heated thermoplastic, paint and the new, environmentally preferred, thin line thermoplastic. The machine is propelled by hydraulic wheel motors. A primary material tank comprises a pressurized interior vessel that is substantially surrounded by a heating fluid circulation jacket. A third wall around the fluid circulation jacket provides a heat riser insulating space. Combustion products from a burner head below the circulation jacket rise through the insulating space. A coaxial flow channel around the conduits that deliver the striping material to a spray head carries heat transfer medium such as hot oil drawn from the heating fluid circulation jacket.

  • Patent number: 5776268
    Abstract: A process for progressively manufacturing cutting edge needles or wire members. Needle blanks or wire blanks are cut from a roll of wire and mounted to a carrier strip. The carrier strip and needles are moved through a succession of coining dies and at least one trimming die, wherein the first coining die is an open coining die and the one or more successive coining dies are closed coining dies. The needle blanks or wire members are optionally curved, heat treated and electrochemically treated resulting in cutting edge needles or wire members formed without a grinding step and without adversely affecting point ductility.

  • Patent number: 5578150
    Abstract: A conveyor moves forward an unconcentrically spiralled loose coil of steel wire rod having a temperature not lower than Ar.sub.3 into a retention bath of molten salt for heat treatment. Just before entering the retention bath, the coil is quenched by spraying a solution of molten salt kept at a temperature between 400.degree. and 600.degree. C. and not higher than the temperature of the retention bath either from above and below or from only above the coil. Then, the quenched coil is retained in the retention bath of molten salt kept at a temperature between 400.degree. and 600.degree. C., thereby causing pearlite transformation and forming a fine pearlite structure in the wire rod.
