Ukushisela kweamashubhu ethusibekulokhu kuyingxenye ebalulekile yokukhiqizwa nokusetshenziswa kwamashubhu ethusi.Phakathi nokusebenza okujwayelekile okunjalo, izinkinga ezincane ezihlukahlukene zivame ukwenzeka.Siyishisela kanjani ithubhu yethusi, isinyathelo esilula siboniswa lapha namuhla.
(1) Ukulungiselela kokuqala
Ngaphambi kokushisela, kuyadingeka ukuba nokuqonda okuthile ngezinto zokushisela, amathuluzi wokushisela, kanye nezidingo zokukhiqiza.Kuyadingeka ukuhlola ukuthi igesi ehambisanayo ku-cylinder ye-oxygen kanye ne-second block gas cylinder yanele, ukuhlolwa kwangaphambilini kwengxenye ngayinye kuqinile, futhi ubuso bezinto ezibonakalayo bucwebezelisiwe buhlanzekile, njll. , lezi ziyisiqalo sokuqala amalungiselelo
(2) Ukushisela
Lapho ushisela, kuyadingeka ukushisa ithubhu yethusi, ukushisa indawo lapho ithubhu yethusi idinga ukushiswa ngelangabi, futhi ubheke umbala.Ngokuvamile, okubomvu okumnyama kungaba ngu-600 degrees Celsius, okubomvu okujulile cishe kungama-700 degrees Celsius, kanti okuwolintshi cishe kungama-degree Celsius ayi-1000.
Ngesikhathi senqubo yokushisela, izingxenye ezilimele zivikelekile.Ngokuvamile, i-valve ye-solenoid, i-valve yezindlela ezine, njll. kufanele ihlakazwe bese ishiselwa okwesibili.Ilangabi lokushisela alikwazi ukusetshenziswa njenge-electrode yokushisa.Phakathi nenqubo ye-welding, i-welding kufanele igcwaliswe ngokushesha futhi ngokunembile, okungcono ngesikhathi esisodwa.Lapho ukushisela sekuzophela ukuze kufakwe i-annealing, izinga lokushisa lilawulwa cishe ngama-degree angama-300
(3) Ngemva kokushisela
Ngemva kokuphothulwa kokushisela, kufanele kupholiswe isikhathi esithile, futhi i-oxide, uthuli kanye nenye i-slag yokushisela epayipi lethusi kufanele ihlanzwe nge-nitrogen eyomile, futhi ezinye izindawo zokushisela ezingekho kufanele zilungiswe.Ngaphambi kokulungisa i-welding, ungqimba lwe-oxide ebusweni kufanele lususwe.Ngemva kokukhanda ukushisela, ingxenye ene-oxidized isadinga ukuphathwa, futhi ngemva kokuqedwa, iphinde iphathwe ngokushaywa komoya ukuze kugcinwe udonga lwangaphakathi lweshubhu yethusi lomile kanye nodonga lwangaphandle luqinile.
