I-FIXDEX Factory2 SS304 SS316 I-BOD egcwele threaded rod / ibha ye-threaded / stud bolt

Ungayibona kanjani ikhwalithi ye-bar engagqwali yensimbi engagqwali / ibha ye-threaded / Stud Bolt?

1. Ukutholwa kazibuthe

Uthe insimbi engagqwali ingubuthe, kwesokudla! Kuyiqiniso futhi ukuthi akuyona uMagnetic! Eqinisweni, empeleni ahlukile. Sonke siyazi ukuthi i-steel engenasici ihlukaniswe ngensimbi yensimbi engenasici kanye nensimbi engenacala. Insimbi engenacala engagqwali ayizibuthe, ngenkathi insimbi engenacala ye-Ferritic iyinsimbi eqinile kazibuthe. Ngochungechunge lokuhlolwa, kufakazelwa ukuthi insimbi engenacala engagqwali izoba nobude obucashile ngaphansi kwezimo ezithile ezikhethekile, kodwa kungeyona in-magnetic ngaphansi kwezimo ezijwayelekile.

2. Yenza ukuhlolwa kwe-nitric acid point

Ezimweni eziningi, kunzima ukuhlukanisa uchungechunge olungama-200, ama-300ries ​​angama-300, uchungechunge olungu-400 nezinye izinhlobo zensimbi engenasici ngeso elinqunu. I-Nitric Acid Point Test iyindlela yokuhlola enembile kunazo zonke yokuhlola ukumelana nokugqwala kwe-substrate. Imvamisa, uchungechunge lwama-400 luzogcwala kancane ngesikhathi sokuhlolwa, kuyilapho insimbi engama-200 yensimbi engenacala ngokumelana nokugqwala okuphansi kakhulu kuzoba namamaki asobala wokugqwala.

3. Ukuhlolwa kobulukhuni

Uma insimbi engenasici i-autenitic izokhombisa uMagnetism othile lapho kubanda ngaphansi kwengcindezi yezulu, khona-ke ukuhlolwa kokuqala kazibuthe okusanda kushiwo akuvumelekile; Ngakho-ke sidinga ukushisa insimbi engagqwali kuye cishe ngo-1000-1100 ℃ bese amanzi aqeda ukuqeda uzibuthe wensimbi ye-auntenitic yensimbi futhi ahlole ubulukhuni. Ubulukhuni bensimbi e-auntenitic engagqwali imvamisa ingaphansi kwe-RB85

Ngaphezu kwalokho

Ubulukhuni bama-430, 430F kanye ne-466 zensimbi kungaphansi kwe-RC 24

Ubulukhuni bakwa-410, 414, 416 no-431 yi-RC36 ~ 43

Ubulukhuni be-carbon ephakeme 420, 420F, 440A, B, C no-T yensimbi yi-RC50 ~ 60

Uma ubulukhuni bungu-RC50 ~ 55, kungaba ngensimbi engu-420

Ubulukhuni be-440A e-440A ne-B amasampula yi-RC55 ~ 60

Inani le-RC le-60 noma ngaphezulu liyinsimbi engu-440c.

4. Ngokuhlola amainintshi

Uma insimbi engenasici ihlolwe injwe, kunconywa ukuyiyisa ku-lathe ejwayelekile noma i-CNC LATE yokuhlolwa kwemishini, kepha kusekhona ukulinganiselwa. Le ndlela ilungele kuphela insimbi yokusika kanye nensimbi ejwayelekile engenacala, njenge-303, 416, 420f, 430f, 440f. Uhlobo lwensimbi lukhonjwa ngesimo sama-chip ajikayo. Lolu hlobo lwensimbi elula luzokhipha iphunga elingajabulisi lapho liphenduka isimo esomile.

I-5. I-phosphoric acid ukutholwa

Le yindlela yokutholwa esiyisebenzisa kaningi empilweni yansuku zonke. Le ndlela isetshenziselwa ukwahlukanisa insimbi engenasici ye-chromium-nickel. Faka i-phosphoric acid ehlanganisiwe ku-0.5% sodium fluoride solution bese uyishisa ku-60-66 ℃.

I-6. Ukutholwa ngephuzu le-sulfate yethusi

Le ndlela ingabona insimbi ejwayelekile yekhabhoni nensimbi engenasici. Ukuhlushwa kwesixazululo se-sulfate yethusi kumele kube phakathi kuka-5% no-10%. Lapho wehla ngensimbi ukuze ihlolwe, ungqimba lwensimbi yensimbi luzokhe ebusweni bensimbi evamile yekhabhoni kungakapheli imizuzwana embalwa, kanti ingaphezulu lensimbi engenasici lizohlala lingashintshiwe.

7. Ukutholwa kwesisombululo se-sulfuric acid

Le ndlela ingahlukanisa ama-302, 304, 316, kanye nama-317 ama-steel angenasici. Lungiselela i-sulfuric acid ngenhlanganisela engama-20% kuya ku-30% kanye namazinga okushisa acishe abe ngu-70 ° C, bese ubeka insimbi ukuthi ihlolwe kwikhambi. Ama-302 futhi ama-304 ama-stainless azokhiqiza inani elikhulu lama-bubble lapho ahlangabezana nesixazululo futhi azophenduka abe mnyama kungakapheli imizuzu embalwa;

Ngokuphambene nalokho, ama-316 kanye nama-317 ama-steel angenamicibiwe ngeke akhombise ukusabela okukhulu kwikhambi, futhi ngokuyisisekelo ngeke aphenduke amnyama kungakapheli imizuzu eyi-10 kuye kwayi-15.

8. Ukutholwa kwe-Cold Acide Point

Uhlobo olufanayo lwensimbi engenasici lungahlukaniswa ngokudonsa isixazululo se-sulfuric acid esingu-20% ngaphezulu kwesampula elisebusweni, libunjiwe, lihlanziwe noma licwebezelwe.

Donsela amaconsi ambalwa wekhambi le-acid ebusweni besampula ngayinye. Ngaphansi kwesenzo sekhambi le-acid, ama-302 kanye nama-304 ama-stainless ama-stainle agcwala ngokuqinile futhi ajika amnyama, abonise abamnyama abumnyama noma abamnyama, bese amakristalu aluhlaza akhiwa kwikhambi;

316 Izinsimbi ezingenasici ezingenasici kancane kancane futhi kancane kancane zijike aphuzi-ziphuzi, bese ziphenduka zinsundu - bese ekugcineni zikha amakristalu amnyama amnyama esikhaleni; Ukusabela okungenhla kwensimbi engama-317 yensimbi kuqhubeke kancane.

9. Ukuqashelwa ngokusebenzisa izinhlansi

Ukuhlolwa kweSpark kusetshenziselwa ukwahlukanisa insimbi ye-carbon, i-alloy yensimbi yensimbi kanye nensimbi yethuluzi, kepha kusetshenziswa okuncane ekuhlukaniseni insimbi engagqwali. Le ndlela yokuhlola ye-Spark ingasiza abasebenzi abanolwazi ukuthi bahlukanise insimbi engagqwali ibe yizigaba ezine ezinkulu, kepha akulula ukuhlukanisa phakathi kwamabanga ahlukile ensimbi.

Izici zeSpark Stark yalezi zigameko ezine zemishini yensimbi engenasici zimi ngokulandelayo:

I-Class A: 302, 303, 316 Insimbi, ikhiqiza izinhlansi ezibomvu ezibomvu ngemfoloko eziningana.

I-Class B: 308, 309, 310 ne-446 yensimbi, ekhiqiza izinhlansi ezimbalwa ezibomvu ezimnyama ezimnyama ezinamaforakhi ambalwa.

I-Class C: 410, 414, 416, 416, 430 no-431 insimbi, ekhiqiza izinhlansi ezinde ezimhlophe ngemfoloko eziningana.

I-Class D: 420, 420F no-440a, B, C, F, ukukhiqiza ama-Shimmering Colour Spark ngokukhanya okusobala noma izinhlansi ezinde ezimhlophe.

10. Ngokuthola ukutholwa kwe-hydrochloric acid

Le ndlela yokutholwa ingahlukanisa ama-403, 410, 416 insimbi engagqwali enokuqukethwe okuphansi kwe-chromium kusuka ngo-430, 431, insimbi engagqwali, 446 insimbi engagqwali enokuqukethwe okuphezulu kwe-chromium

Shintsha inani elilinganayo lokusika isampula kukhambi le-hydrochloric acid ngesimo sevolumu sama-50% cishe imizuzu emithathu, bese uqhathanisa ukuqina kombala kwesisombululo. Insimbi enokuqukethwe okuphezulu kwe-chromium inombala oluhlaza okotshani.
