METHOD FOR USING METALLURGY FABRICATION FOR MANUFACTURING AN INTEGRATED HEADER AND TUBE REPLACEMENT SECTION FOR EASY CNC MILLING AND BORING

摘要

PURPOSE: A method for using metallurgy fabrication for manufacturing an integrated header and tube replacement section is provided to reduce lead time and the number of welding spots for a header replacement section.;CONSTITUTION: A method for manufacturing an integrated header and tube replacement section comprises the steps of: preparing a reverse mold for a head and tube replacement section(12), filling the reverse mold with atomized metal powder(13), inserting the mold into a High-temperature Isostatic-pressure Processing(HIP) furnace to integrate the powder into a head and tube replacement section, and vacuumizing the mold to remove air pockets.;COPYRIGHT KIPO 2013;[Reference numerals] (11) Designing reproduction header; (12) Preparing reverse mold; (13) Filling reverse mold with atomized powder; (14) Evacuating and sealing mold; (16) High-temperature isostatic-pressure processing; (17) Maintaining at sintering temperature; (18) Cooling to room temperature; (19) Thermal processing?; (20) Removing from mold; (21) Washing/Grinding; (22) Boring; (23) Chamfering
