I-1, i-Spheroidizing annealing yamabhawodi anamandla amakhulu

Lapho amabhawodi ekhanda lesokhethi ye-hexagon ekhiqizwa inqubo yesihloko esibandayo, ukwakheka kwangempela kwensimbi kuzothinta ngqo ikhono lokwakha ngesikhathi sokucutshungulwa kwesihloko esibandayo. Ngakho-ke, insimbi kufanele ibe nepulasitiki enhle. Lapho ukwakheka kwamakhemikhali ensimbi kuhlala njalo, ukwakheka kwe-metallographic kuyisici esibalulekile esinquma ipulasitiki. Ngokuvamile kukholakala ukuthi i-pearlite egqagqene egqagqene ayihambisani nokwakheka kwesihloko esibandayo, kuyilapho i-pearlite eyisiyingi ecolekile ingathuthukisa ngokuphawulekayo ikhono lokuguga lepulasitiki lensimbi.
Ngensimbi ye-carbon steel ne-medium carbon alloy steel enenani elikhulu lezibophelelo ezinamandla amakhulu, ukufakwa kwe-spheroidizing annealing kwenziwa ngaphambi kwesihloko esibandayo, ukuze kutholwe i-pearlite efanayo nenhle ye-spheroidized ukuze kuhlangatshezwane kangcono nezidingo zangempela zokukhiqiza.

2, Ukugoqa kanye nokwehliswa kwamabhawodi anamandla amakhulu

Inqubo yokukhipha ipuleti le-iron oxide entweni yensimbi enesihloko esibandayo iyahlubula futhi iyehle. Kunezindlela ezimbili: i-mechanical descaling kanye ne-chemical pickling. Ukushintsha inqubo yokukhetha amakhemikhali yenduku yocingo ngokuhlehlisa ngomshini kuthuthukisa ukukhiqiza futhi kunciphisa ukungcoliswa kwemvelo. Le nqubo yokwehlisa ihlanganisa indlela yokugoba, indlela yokufafaza, njll. Umphumela wokwehlisa muhle, kodwa isikali sensimbi esisele asikwazi ukususwa. Ikakhulukazi uma isikali sesikali se-iron oxide sinamandla kakhulu, ngakho-ke ukwehla komshini kuthinteka ubukhulu besilinganiso sensimbi, isakhiwo kanye nesimo sokucindezeleka, futhi sisetshenziswa ezindongeni ze-carbon steel wire for low-power fasteners. Ngemva kokwehliswa kwemishini, induku yocingo yezinsimbi eziqinile ingena inqubo yokukhetha amakhemikhali ukuze isuse zonke izikali ze-iron oxide, okungukuthi, ukwehla okuhlanganisiwe. Ezintini zezintambo zensimbi enekhabhoni ephansi, ishidi lensimbi elishiywe ukusika ngomshini kungenzeka libangele ukuguga okungalingani kokusanhlamvu okusanhlamvu. Lapho imbobo yokusanhlamvu okusanhlamvu inamathela eshidini lensimbi ngenxa yokungqubuzana kwenduku yocingo kanye nezinga lokushisa langaphandle, ingaphezulu lenduku yocingo likhiqiza izimpawu zokusanhlamvu ze-longitudinal.
