Heat Treatment method of precipitation hardened copper alloy tube or tube for mass production

摘要

The present invention relates to a heat treatment method for precipitation hardening type alloy tube or rod of mass production, and more particularly making the copper alloy castings, to produce a product of middle size by extrusion and general process the casting, excellent electrical conduction through the solution heat treatment and aging treatment and subsequent uniform with high hardness can ensure the high quality and uniform quality is productive of a high precipitation hardening type alloy rod or tube to heat treatment method for mass production. ; According to the invention, supersaturated 50-100 minutes at 1,030 ~ 1,070 hardness compensating for the alloying elements in the material Embodied step, embodied for precipitation hardening type copper alloy tube or rod and heat treatment method for mass-producing composed of water-cooled quench within seven seconds in steps of less than 50 for material to employment; Transferring a large amount of the material by a plurality of rollers that jeokchi driven by the motor transport unit, the inlet and the gate is installed at the outlet, a plurality of rollers driven by a motor is disposed inside, heat treatment and receptor by a heating device a heating unit for a plurality of rollers driven by a motor is provided, and is fastened to the lifting cylinder for the lifting movement and sedimentation, precipitation hardening type alloy rod or tube is configured to include a large amount of quench water bath consisting of immersion for the sedimentation for the production of heat treatment system is provided.
