Ts’ebetso e potlakileng ea ho khothaletsa spheroidizing bakeng sa ho futhumatsa sebōpi
The ente e futhumatsang mollo ts’ebetso e potlakileng ea ho koala spheroidizing ke mohato o kopantsoeng oa spheroidizing o phetheloang ke boapeelo ba ho futhumatsa bo futhumatsang le sethala sa boitokisetso ba spheroidizing, mme sethala sa spheroidizing se phetheloa ke ho futhumatsa ha setso. Fana ka papali e felletseng ho litšobotsi tsa mekhoa e ‘meli ea ho futhumatsa’ me u kopane ho etsa ts’ebetso e ncha e potlakileng ea ho khothaletsa spheroidizing.
Ho sebelisoa litšobotsi tsa mocheso o potlakileng oa sebōpi sa ho futhumatsa bakeng sa ts’ebeliso ea matlafatso, ho fumanoa likristale tse ntle tsa austenite, tse hlahisang lintho tse hlokahalang bakeng sa pholileng e latelang ho fumana lithollo tse ntle. Ho ea ka maemo a fapaneng a ho futhumatsa austenitizing, likarolo tse fapaneng tsa pele tsa spheroidizing lia fumaneha. Mefuta e fapaneng ea litokisetso tsa spheroidizing e entsoe ka spheroidized le annealed ho sebelisa mekhoa ea setso ea ho futhumatsa hore qetellong e fumane lisele tsa spheroidizing.
Ho latela maemo a fapaneng a ho futhumatsa austenitizing, sebopeho sa boitokiso ba spheroidizing se arotsoe ka mefuta e meraro e latelang:
(1) The spheroidized tsa go baakanyetsa sebopeho thehoa ke moea tsidifatso (normalizing) ke pearlite.
(2) Sebopeho sa spheroidization se entsoeng ka ho futhumatsa ha metsi (ho tima) ke martensite + e bolokileng austenite.
(3) Sebopeho se hlophisitsoeng se hlophisitsoeng hantle se entsoeng ke ho futhumatsa ha metsi (ho futhumatsa khafetsa le ho tima kaholimo ho 400 ° C) ke sorbite.
