Ukuze kuphuculwe ubulukhuni bomphezulu kunye nokumelana nokunxiba16Mn iityhubhu ezixande, unyango oluphezulu, olufana nomlilo womlilo, ukucima i-high-frequency surface, unyango lokushisa kweekhemikhali, njl. Ngokubanzi, uninzi lweendawo eziphakamileyo neziphakathi ziyacinywa, kwaye ubushushu bobushushu bungama-850-950 degrees. Ngenxa yokungahambi kakuhle kwe-thermal, isantya sokufudumala akufanele sikhawuleze. Ngaphandle koko, iintanda ezinyibilikayo kunye neentanda ezicimayo ziya kuvela. Ukucinywa kwamatyeli aphezulu kufuna ukuba i-matrix yesiqhelo ibe yipearlite. Ukupholisa amanzi okanye isisombululo sotywala se-polyvinyl. Ubushushu bobushushu bungama-200-400 ℃, kwaye ubunzima bungama-40-50hrc, obunokuqinisekisa ukuqina kunye nokumelana nokunxiba.ityhubhu yesikwereumphezulu.
La manqaku alandelayo aya kuqatshelwa xa kucinywa16Mn square tube:
(1)Umbhobho omde awusayi kutshiselwa ngokuthe nkqo kwiziko lokuhlambela ityuwa okanye kwiziko lomthombo kangangoko kunokwenzeka, ukuze kuncitshiswe ukonakala okubangelwa bubunzima bomnatha.
(2)Xa ukufudumala imibhobho ngamacandelo ahlukeneyo kwisithando somlilo esifanayo, iibhobho ezincinci ziya kufakwa ekupheleni kwangaphandle kwesithando somlilo, kwaye imibhobho emikhulu kunye nemibhobho encinci iya kugqitywa ngokwahlukileyo.
(3)Imali nganye yokutshaja iya kuhambelana nenqanaba lamandla eziko. Xa isixa sokutya sikhulu, kulula ukucinezela kunye nokunyuka kweqondo lokushisa, kwaye ixesha lokufudumala lifuna ukwandiswa.
(4)Ubushushu bokucima kweetyhubhu ezisikwere ezicinyiweyo ngamanzi okanye i-brine iya kuthathwa njengomda osezantsi, kwaye ubushushu bokucima i-oyile okanye ityuwa enyibilikisiweyo ecinyiweyo iya kuthathwa njengomda ongaphezulu.
(5)Ngexesha lokucima okuphakathi kabini, ixesha lokuhlala kwindawo yokuqala yokucima liya kulawulwa ngokweendlela ezintathu ezingentla. Ixesha elihambayo ukusuka kwindawo yokuqala yokucima ukuya kwinqanaba lesibini lokucima liya kuba lifutshane kangangoko kunokwenzeka, ngokukhethekileyo i-0.5-2s.
(6)Imibhobho engavunyelwanga ukuba ifakwe kwi-oxidation okanye i-decarburization iya kufudunyezwa kwiziko lokuhlambela ngetyuwa elilungisiweyo okanye kwisithando somlilo esikhuselayo. Ukuba ayihambisani neemeko, inokufudumeza kwisithando somlilo sokumelana nomoya, kodwa amanyathelo okukhusela kufuneka athathwe.
(7)Emva kokuba ityhubhu ye-16Mn ye-rectangular ifakwe ngokuthe nkqo kwindawo yokucima, ayijingi, inyuke kwaye ihle, kwaye iyeke ukushukuma kwendawo yokucima.
(8)Xa amandla okupholisa amacandelo afuna ubulukhuni obuphezulu akwanelanga, yonke inxalenye inokuntywiliselwa kwindawo yokucima ngexesha elinye, kwaye iindawo zinokupholiswa ngokutshiza ulwelo ukuphucula isantya sokupholisa.
(9)Kufuneka ibekwe kwindawo esebenzayo yokufudumeza. Isixa sokuhlawula, indlela yokuhlawula kunye nefom yokubeka i-stacking iya kuqinisekisa ukuba ubushushu bokufudumala bufana, kwaye akunakwenzeka ukuba kubangele i-deformation kunye nezinye iziphene.
(10)Xa ufudumeza kwisithando somlilo setyuwa, asiyi kusondela kakhulu kwi-electrode ukuphepha ukushisa kwendawo. Umgama uya kuba ngaphezulu kwe-30mm. Umgama ukusuka eludongeni lwesithando somlilo kunye nobunzulu bokucwiliswa ngaphantsi komgangatho we-liquid uya kulingana ne-30mm.
(11)Intsimbi yesakhiwo kunye nentsimbi yekhabhoni inokufudumeza ngokuthe ngqo kwiziko elinokushisa okucimayo okanye i-20-30 ℃ ephezulu kunobushushu bokucima. Ikhabhoni ephezulu kunye nentsimbi ephezulu yealloy iya kufudunyezwa malunga ne-600 ℃ kwaye emva koko iphakanyiswe kwiqondo lokucima.
(12)Ubushushu bokucima bunokwandiswa ngokufanelekileyo kwimibhobho enomaleko obunzima obunzulu, kwaye iqondo lokushisa elisezantsi lokucima lingakhethwa kwimibhobho enomaleko wokuqina ongekho nzulu.
(13)Umphezulu we-16Mn yesikwere ityhubhu awuyi kuba neoli, isepha kunye nobunye ubumdaka. Ngokusisiseko, iqondo lobushushu lamanzi aliyi kuba ngaphezu kwe-40 ℃.
