ibhoro emfula yesele 321

Umthombo Omdala
1.Umthombo wokusha lesisheqezulu usetyenziswa ngokuvavanywa kunye nokuhlola kwezinto, kunye nezi zikhona ezininzi:

2.Umthombo wokusha lesisheqezulu lweAustenitic: njengesi 304 (06Cr19Ni10), 316 (06Cr17Ni12Mo2), uhlu lwemfuphi yokuhlola, ayishayamagnesi, asibonisi kwiindawo zakabili, izintaba, nokubhekisisa kunye nesinye.

3.Umthombo wokusha lesisheqezulu lweMartensitic: njengesi 420 (20Cr13), 440 (90Cr18), ukusukela okuhle, ukugcina umoya, usetyenziswa ngokubanzi kumakhetho amanqaku, iibharingi kunye nesinye.

4.Amiselwano esiferritic: njengokuba 430 (10Cr17), ukungabuyiselwa kumthetho, uphansi kunye nomdinga, kodwa kuhlukele ngephakathi, kulandelwe ngazo zonke izidingo lokusebenza. Iphepha amaphrojekti.

5.Amiselwano eduplex: njengokuba 2205 (022Cr23Ni5Mo3N), kunezinye zezilimi ezilandelayo neziferritic, ungenzi lokungakhulu kunye nokungabuyiselwa kumthetho olunomthelela, sibhidwa phakathi komlilo womhlaba kunye nemfundo yemikrosophi.

Izicwangciso ezimbini
1.Isiphumo: indawo eluhlukileyo, indawo esincinci, indawo esisheshe, indawo elandelayo, noma okukeni.

2.Umgeni/Umbiko Wesithuthi: Indawo eluhlukileyo usenokubala Φ1mm~Φ300mm, umbiko wesithuthi wesincinci kunye nesisheshe wakhiwo 3mm~100mm.

3.Inhlanganiso: Ukuphakamiswa okwesintu kwezindlela ezincane zikhulu ngokubanzi 1m~6m, futhi ungathintele ukuba uhlaleke amasayizi aokugciniwe okanye amacacile.

Inqubo Yokukhiqiza
1.Ukugqibela okungumhlabathi: ukugqibela nokulanda ngomphilo engakhulu, isiphupo esihle sasihlangene, sesibonisa amabhopho engakhulu.

2.Ukukhupha ngemvume (ukugqibela ngemvume): uphucamelo lwendawo lokusebenza, inhlanganiso yamagama ehlinzekileyo, isiphupo sasihle, imibuzo yomekanikali yayidinga kulandelana.

3.Ukufundziswa: Ukusetha idensity nesithole ngokufundziswa, usetyenziswa ngamaphishi apho akudingekanga.

Amahlelo amaphi
1.Ukulandelayo: i-chromium iphawuli le 10.5% ukuze kuhluleke umthengamo wokuphawula, ukulandelayo kwe-acid, -alkali, kunye nomthengamo we-salt spray (316 ngokusho lwakho lomolybdenum, ukulandelayo kukuhle kakhulu).

2. Umphumela okukhulu: i-martensitic kunye ne-duplex stainless steel ifomula yethemba ngokwesobizo uphume 500MPa okanye ngaphandle.

3. Ukugcina kwezinsimbi ezintsha kunye nezintsha zikhulu: amahlayo angamashumi amabili (ngokusho 310S) azogcina izinto eziphumayo nge-1000 ℃ noma -196 ℃ ezintsha.

4. Ukusebenza kusenziwa ngokucacileyo: ungathintele, ungenziwe, uqondelwe, ungavavazekile ukuvumela izinhlobo eziningi.

Isicelo izindawo
1. Isigaba sentsha: amabhulu, amahlaba, amaphu athole kunye nemibhalo yebhala, imibhalo yesikhemisi.

2. Ukuhlawuluka: amakhamba okuzameka, amaphuphu, amaphuphu wokungena kwesayithi.

3.Igama lezincwadi: amathuluzi amaphutha, amakhomphaketho (ngasinye sokuqala 316L).

4.Inyama: imibiko yokuphatha kwezincwadi, indlela yocula esebenzayo (kufuneka i-food grade 304/316).

5.Umnotho: umnotho womkhulu, izilondolozi zezichanekileyo ezintshangeni tsha-oolifini.

Ukuphathwa Kwemvelo
1.Isiphumo semncane: uphawu olungazinamandla, ngumoya nokuhlela kucinzwa.

2.Isiphumo semanzana: hlayisa umlando wemfuyo, phumelela ukugcwaliswa kokukhombisa.

3. Umsindo wesandile/ubrushwe: uqaphele umthetho nokugcina amathumbu aqhakamandla.

Amaninzi kanye nezinye izindaba zokukhetha kunye nokuthengisa
1. Ucinga lwezilungiselelo: Bheka iindlela ezithethwayo kweASTM, GB, JIS nokulandlela (ngisho 304 kufuneka ikholelwe ngeASTM A276).

2. Ukusetyenziswa kwenkathi: ukusetyenziswa kwenkathi yomoya omncane zikhetha 316, ukusetyenziswa kwenkathi yokuhlula kuhlu zikhetha 310S.

3. Amahhala angaphandle kwezindlela: uphawu lokulima kufuneka zikhethwe amabhopho oludumelekile ukuguquketha.

Ukhomba nokubonisa
1. Ngokwesikhathu sula umphako wemithombo ethunyelwe ukuvimba okugcineni amaphara engamashumi angendlela (njenge-salt).

2. Ngemuva kokuhlanganisa, kufuneka usetyenziswa lokuhlola kubheka okanye lokuhlola ukususa ukuhlolwa kokuncedwa.

Ukukhetha kwesithuthi esesihlaleni kufanele lisho imibiko, uproseshi neuphindo lwesikhatsi, ukukhetha okungakho kungavulise izicwangciso ezifanekisayo nokugcina imali.
