摘要： PURPOSE:To perform stably local hardening of a turbine blade consisting of a base metl which is an alloy steel having small tensile stress by a simple method by immersing partly the non-hardening part of said turbine blade into water and preheating the boundary part between the hardening part and the immersed part to a prescribed temp. then heating the hardening part to a hardening temp. CONSTITUTION:The front edge 3 of the turbine blade 1 is held horizontal and part of the non-hardening part 2a under the hardening part 2 is immersed in the water 11. The water in a water tank 10 is then circulated 13 and the boundary part 31 between the part 2 and the immersed part, i.e., the part 2a is preheated to 300-400 deg.C by plural pieces of auxiliary burners 32. A main burner pipe 5 is then moved from one end toward the other end of the part 2 and while the flame of the burner 32 is successively shut off, the part 2 is successively heated to 900-1,000 deg.C by the flame of the main burner pipe 5. When the flame of the pipe 5 passes by, the part 2 is deprived of heat by the water in the tank 10 and is thereby hardened. The hardened part 2 having hardening hardness of about 450-500 Vickers hardness and small residual tensile stress is tably obtd.

摘要： PROBLEM TO BE SOLVED: To reduce labor and weight of a equipment-material in welding process and postheating treatment of a heat treatment rail for reducing operating burden, to prevent from accident and to increase working efficiency. SOLUTION: In an postheating treatment method where a weld zone of a heat treatment rail is air cooled down after re-heating, a pre-heating burner for welding is also used for the postheating treatment in common and the postheating treatment burner is used with an oxygen and propane burner an oxygen pressure 4.0 kgf/cm2 or more and a cooling air amount 2.2 cm3/min. or more are used for the burner.

摘要： PROBLEM TO BE SOLVED: To facilitate driving into a base material, and to increase extracting resistance at its extracting from the base material by heating a fastener for quenching, and forming an acrylic polymer coating, while quickly cooling the fastener in the water base medium which includes the acrylic polymer. SOLUTION: A continuous stitch body 10 is maintained by wires 14, 16 welded to narrow and long fasteners 12, and the fastener 12 includes a head part 18 and a shaft part 20 and includes carbon steel, stainless steel, aluminum or the like in response to the final use and the base material of driving without limiting the combination thereof. Each fastener 12 is coated with a thin polymer coating 34, and the coating 34 coats one or more specified parts or the whole of each fastener 12 in response to the purpose of use, and the coating 34 is composed of the acrylic polymer, copolymer, derivative thereof, and combination thereof. Before coating the coating 34, the fastener 12 is heated to about 204-1,093 deg.C and dropped into a water base medium which includes the polymer so as to be quenched. Driving into a base material is thereby facilitated, and extracting resistance can be improved.
