Ukusebenza Kokushisa Okuphezulu
Okuqukethwe okuphezulu kwe-tungsten kwe-H21 kusekela ubulukhuni obushisayo kanye nokumelana nokuthamba ekushiseni okuphezulu. Kukhethwa amathuluzi avulekele ukuthintana kwensimbi eshisayo, ukushisa nokupholisa okuphindaphindiwe, kanye nokuguguleka ngaphansi kwesevisi yokushisa okuphezulu. Ukusebenza kwangempela kuncike ekushiseni, ingcindezi yokuthintana, ukuqina kokupholisa kanye nokugcotshwa.
Ukusebenziseka kalula
Ukukwazi ukusebenza kahle kwemishini ngokuvamile kungcono esimweni esifakwe emanzini abandayo. Ukujika okukhulu, ukugaya, ukubhoboza kanye nokulungisa imishini ngokungemthetho kuvame ukuqedwa ngaphambi kokuqinisa nokushisa. Ngenxa yokuthi i-H21 iqukethe izinga eliphezulu le-tungsten, ukukhetha amathuluzi, isivinini sokusika kanye nokulawula okupholisayo kufanele kuhlelwe ngokucophelela.
Ukwelashwa Kokushisa
I-H21 ivame ukuboshwa ngaphambi komshini bese iqiniswa futhi iqiniswe ukuze ifinyelele ukuqina okufunekayo kokusebenza. Amapharamitha okuqinisa, ukucima kanye nokushisa kumele akhethwe ngokuya ngosayizi wesigaba, umoya wesithando, ukuqina kwenhloso kanye ne-geometry yokushisa. Ukushisa ngesikhathi sesevisi kuvame ukuba kubalulekile ukunciphisa ukushaqeka kokushisa.
Ukushisela Nokulungisa
Ukulungisa ukushisela kungenzeka ngenqubo yokushisela efanelekile, insimbi yokugcwalisa efanelekile, ukwelashwa kokushisa kwangaphambili kanye nokwelashwa kokushisa ngemva kokushisela. Kuma-dies okushisa abalulekile, izinqumo zokulungisa kufanele zicabangele ingozi yokuqhekeka, umehluko wobunzima, izinga lokushisa lesevisi kanye nokuphila kwethuluzi elisele.
Kungani Ukhetha I-SAKY STEEL?
Ububanzi, ubude, ukuqeda ubuso kanye nemvume yokulungisa kunganikezwa ngokwemidwebo.
Ukuhlonza izinto kungagcinwa kusukela ezincwadini kuya ekupakisheni kokugcina.
I-MTC (iSitifiketi Sokuhlolwa Kwesigayo / 质保书) inganikezwa ngokwe-oda lokuthenga.
Imibhalo ye-EN 10204 3.1 iyatholakala uma ichazwe yi-oda.
Ukuqina, ubukhulu, ukuhlolwa kwe-PMI kanye ne-UT kungahlelwa uma kuchazwe.
Kungahlelwa amaqoqo, amakesi okhuni, ama-pallet kanye nezimpawu zokuthumela zamakhasimende.
Imibuzo Evame Ukubuzwa
Iyini insimbi yamathuluzi ye-DIN 1.2581 H21?
I-DIN 1.2581 H21 iyinsimbi yamathuluzi okusebenza ashisayo exutshwe ne-tungsten. Isetshenziselwa amathuluzi asebenza ngaphansi kokushisa okuphezulu, ukuguguleka kanye nokujikeleza kokushisa, njengezinsimbi zokufaka ezishisayo, ama-hot punches kanye namathuluzi okukhipha.
Ingabe i-H21 iyafana ne-SKD5?
I-H21 kanye ne-SKD5 zivame ukusetshenziswa njengezinkomba zohlobo olufanayo lwensimbi yamathuluzi okusebenza ashisayo e-tungsten. Ukulingana kokugcina kufanele kusaqinisekiswe yizindinganiso ezidingekayo, ukwakheka kwamakhemikhali, ukwelashwa kokushisa kanye nezidingo zokuhlola.
Yiliphi izinga elisebenza kubha yensimbi yamathuluzi e-H21?
I-ASTM A681 ivame ukubhekiselwa kunsimbi yamathuluzi ye-AISI H21, kuyilapho i-DIN EN ISO 4957 ingasetshenziswa ku-DIN 1.2581 / X30WCrV9-3. I-oda lokuthenga kufanele lichaze indinganiso edingekayo kanye nokubuyekezwa.
Iyini inzuzo enkulu ye-H21 uma iqhathaniswa ne-H13?
I-H21 iqukethe i-tungsten ephezulu kakhulu, ethuthukisa ubulukhuni obubomvu kanye nokumelana nokuthamba kwezinye izinhlelo zokusebenza zokushisa okuphezulu. I-H13 isetshenziswa kabanzi futhi inikeza ibhalansi ehlukile yokuqina, ukumelana nokukhathala kokushisa kanye nokutholakala.
Ingabe ibha ye-H21 inganikezwa igayiwe noma ihlutshulwe?
Yebo. Izindawo ezimnyama, ezihlutshiwe, eziphendukile kanye nomhlabathi zingaxoxwa ngokuya ngobubanzi, ukubekezelelana kanye nesidingo sokugcina somshini. Imigoqo yomhlabathi ifanelekile lapho kudingeka khona ukulawulwa kobubanzi obuqinile noma ukuqeda okuthuthukisiwe komhlabathi.
Ingabe ukuhlolwa kwe-ultrasonic kuyatholakala kuma-H21 bar?
I-UT ingalungiselelwa ububanzi bebha obufanele kanye nebha ezibunjiwe uma kuchazwe. I-oda kufanele lichaze indlela yokuhlola, izinga lokwamukelwa kanye nesidingo sokubika.
Ingabe i-MTC kanye ne-EN 10204 3.1 zinganikezwa?
I-SAKY STEEL inganikeza amadokhumenti e-MTC kanye ne-EN 10204 3.1 ngokwe-oda lokuthenga. Imibiko yokuqina, ubukhulu, i-PMI noma i-UT nayo ingahlelwa uma kuchazwe.
