摘要： A system for producing components by hot forming includes a conductive post-furnace heat station, a furnace, a computer system, and a press. The computer system comprises one or more physical processors operatively connected with the furnace in and the conductive post-furnace heat station. The one or more physical processors being programmed with computer program instructions which, when executed cause the computer system to control the furnace to heat the blank to a temperature that is below AC3 temperature; and control the conductive post-furnace heat station to heat a portion of the heated blank to a temperature above the AC3 temperature by thermal conduction. The press is constructed and arranged to receive the post-heated blank from the post-furnace heat station and to form the post-heated blank into the shape of the component.

摘要： Embodiments are described herein of a bifurcated heat treatment apparatus and methods for localized heat treatment of a golf club hosel or golf club head. The heat treating method comprises a bifurcated process in which the golf club head is treated in the first heating unit via induction heating and then moved to the second heating unit for convection heating. Both steps are to localize the hosel heat treatment. The heat treatment apparatus may also include a cooling component, such as a heat sink, to ensure the body of the club head remains at the correct temperature during the second heating stage when the hosel is heated in isolation. The overall bifurcated method and apparatus of the localized heat treatment leads to a hosel or golf club head with at least two different hardness values to allow for manipulation of the material without cracking or fracturing.

摘要： A homogenization process for coiled tubing is provided. After being preheated in a sectional manner and quenched and tempered, laser-welded low-carbon alloy steel coiled tubing is spray cooled, and then is tempered to obtain homogeneous silvery coiled tubing. Microstructural uniformity of the silvery coiled tubing after the treatment is greatly improved in a welding seam region, a heat sensing region, and a tube wall, situations in which an outer surface of the coiled tubing is burnt and oxidized in the homogenization process are reduced, and a service life of the coiled tubing is prolonged. Moreover, homogeneous coiled tubing with different yield strengths and tensile strengths can be obtained by changing a temperature of the tempering, so that production costs are reduced.
