Kodi mungadziwe bwanji mtundu wa ndodo yachitsulo chosapanga dzimbiri/mipiringidzo ya ulusi/bawuti?

1. Kuzindikira maginito

Mwati chitsulo chosapanga dzimbiri ndi maginito, chabwino! Ndizowonanso kuti si maginito! Ndipotu iwo ndi osiyana kwambiri. Tonse tikudziwa kuti chitsulo chosapanga dzimbiri chimagawidwa kukhala chitsulo chosapanga dzimbiri cha austenitic ndi chitsulo chosapanga dzimbiri cha ferritic. Chitsulo chosapanga dzimbiri cha Austenitic sichikhala ndi maginito, pomwe chitsulo chosapanga dzimbiri cha ferritic ndi chitsulo cholimba cha maginito. Kupyolera mu mayesero angapo, zimatsimikiziridwa kuti chitsulo chosapanga dzimbiri cha austenitic chidzakhala ndi maginito osadziwika pansi pa zinthu zina zapadera, koma si maginito nthawi zonse.

2. Pangani mayeso a nitric acid point

Nthawi zambiri, zimakhala zovuta kusiyanitsa mndandanda wa 200, mndandanda wa 300, mndandanda wa 400 ndi mitundu ina yazitsulo zosapanga dzimbiri ndi maso. Mayeso a nitric acid point ndiye njira yoyesera kwambiri yoyesera kukana kwa dzimbiri kwa gawo lapansi. Kawirikawiri, mndandanda wa 400 udzangowonongeka pang'ono panthawi yoyesedwa, pamene zitsulo zosapanga dzimbiri 200 zokhala ndi zotsika kwambiri zowonongeka zidzakhala ndi zizindikiro zowonongeka.

3. Mayeso olimba

Ngati chitsulo chosapanga dzimbiri cha austenitic chidzawonetsa maginito pamene kuzizira kukulungidwa pansi pa mphamvu ya mumlengalenga, ndiye kuti mayesero oyambirira a maginito omwe angotchulidwawa ndi olakwika; kotero tiyenera kutentha zitsulo zosapanga dzimbiri pafupifupi 1000-1100 ℃ ndiyeno madzi kuzimitsa izo kuthetsa maginito austenitic zitsulo zosapanga dzimbiri ndi kuyesa kuuma. Kuuma kwa chitsulo chosapanga dzimbiri cha austenitic nthawi zambiri kumakhala pansi pa RB85

Kuphatikiza apo

Kuuma kwa 430, 430F ndi 466 zitsulo ndizochepera Rc 24

Kuuma kwa 410, 414, 416 ndi 431 ndi Rc36 ~ 43

Kuuma kwa chitsulo cha carbon 420, 420F, 440A, B, C ndi F ndi Rc50 ~ 60

Ngati kuuma ndi Rc50 ~ 55, kungakhale chitsulo 420

Kuuma kwa zitsanzo zozimitsidwa 440A ndi B ndi Rc55 ~ 60

Mtengo wa Rc wa 60 kapena pamwamba ndi chitsulo cha 440C.

4. Kupyolera mu kuyendera makina

Ngati chitsulo chosapanga dzimbiri chomwe chikuyesedwa chiri chofanana ndi shaft, tikulimbikitsidwa kuti mutengere ku lathe wamba kapena CNC lathe kuti muwunikenso makina, koma pali zolephera. Njirayi ndiyoyenera chitsulo chosavuta kudula komanso chitsulo chosapanga dzimbiri, monga 303, 416, 420F, 430F, 440F. Mtundu wachitsulo umadziwika ndi mawonekedwe a tchipisi totembenuza. Chitsulo chophweka choterechi chidzatulutsa fungo losasangalatsa likatembenuzidwira mu nthaka youma.

5. Kuzindikira kwa asidi wa phosphoric

Iyi ndi njira yodziwira yomwe timagwiritsa ntchito nthawi zambiri pamoyo watsiku ndi tsiku. Njirayi imagwiritsidwa ntchito kusiyanitsa chitsulo chosapanga dzimbiri cha chromium-nickel. Onjezani asidi wa phosphoric wokhazikika ku 0.5% sodium fluoride solution ndikutenthetsa mpaka 60-66 ℃.

6. Kuzindikira ndi copper sulfate point

Njirayi imatha kuzindikira chitsulo wamba ndi chitsulo chosapanga dzimbiri. Mulingo wa mkuwa wa sulphate uyenera kukhala pakati pa 5% ndi 10%. Akagwetsedwa pazitsulo kuti ayesedwe, zitsulo zamkuwa zamkuwa zidzapanga pamwamba pazitsulo za carbon zitsulo mkati mwa masekondi angapo, pamene pamwamba pazitsulo zosapanga dzimbiri sizidzasintha.

7. Kupeza yankho la sulfuric acid

Njirayi imatha kusiyanitsa 302, 304, 316, ndi 317 zitsulo zosapanga dzimbiri. Konzani sulfuric acid ndi ndende ya 20% mpaka 30% ndi kutentha kwa pafupifupi 70 ° C, ndikuyika zitsulo kuti ziyesedwe mu yankho. 302 ndi 304 zitsulo zosapanga dzimbiri zidzatulutsa thovu zambiri zikakumana ndi yankho ndipo zidzasanduka zakuda mkati mwa mphindi zochepa;

M'malo mwake, 316 ndi 317 zitsulo zosapanga dzimbiri sizidzawonetsa kuyankha kwakukulu mu yankho, ndipo kwenikweni sizidzasanduka zakuda mkati mwa mphindi 10 mpaka 15.

8. Cold acid point kuzindikira

Mtundu womwewo wa chitsulo chosapanga dzimbiri ukhoza kuzindikirika ndi kudontha 20% sulfuric acid solution pamwamba pa zitsanzo zomwe zatsitsidwa, zopukutidwa, zotsukidwa kapena zopukutidwa.

Ponyani madontho angapo a asidi pamwamba pa chitsanzo chilichonse. Pansi pa njira ya asidi, 302 ndi 304 zitsulo zosapanga dzimbiri zimawonongeka kwambiri ndipo zimasanduka zakuda, zosonyeza bulauni-wakuda kapena wakuda, ndiyeno makhiristo obiriwira amapangidwa mu yankho;

316 chitsulo chosapanga dzimbiri chimawononga pang'onopang'ono ndipo pang'onopang'ono chimasanduka bulauni-chikasu, kenako chimasanduka bulauni-wakuda, ndipo pamapeto pake chimapanga makhiristo obiriwira obiriwira mu yankho; Zomwe zili pamwambazi za 317 zitsulo zosapanga dzimbiri zimapita pang'onopang'ono.

9. Kuyang'ana kudzera m'moto

Mayeso a spark amagwiritsidwa ntchito kusiyanitsa chitsulo cha carbon, chitsulo chopangidwa ndi alloy ndi chitsulo chachitsulo, koma sichithandiza kwambiri kusiyanitsa chitsulo chosapanga dzimbiri. Njira yoyesera iyi ya spark imatha kuthandiza odziwa bwino ntchito kugawa zitsulo zosapanga dzimbiri m'magulu anayi akuluakulu, koma sikophweka kusiyanitsa pakati pa magulu osiyanasiyana achitsulo.

Makhalidwe a spark a magulu anayi awa a makina osapanga dzimbiri ndi awa:

Kalasi A: 302, 303, 316 chitsulo, kutulutsa zipsera zazifupi zofiira ndi mafoloko angapo.

Kalasi B: 308, 309, 310 ndi 446 zitsulo, zomwe zimapanga zochepa zazifupi zofiira zakuda zokhala ndi mafoloko angapo.

Kalasi C: 410, 414, 416, 430 ndi 431 chitsulo, kupanga zowala zazitali zoyera ndi mafoloko angapo.

Kalasi D: 420, 420F ndi 440A, B, C, F, kutulutsa zonyezimira zamitundu yonyezimira zowoneka bwino kapena zowala zazitali zoyera.

10. Kudzera mu hydrochloric acid kuzindikira

Njira yodziwikirayi imatha kusiyanitsa 403, 410, 416, 420 chitsulo chosapanga dzimbiri chokhala ndi chromium yochepa kuchokera ku 430, 431, 440, 446 chitsulo chosapanga dzimbiri chokhala ndi chromium yayikulu.

Sungunulani yofanana yodula zitsanzo mu hydrochloric acid njira ndi voliyumu kachulukidwe 50% kwa pafupifupi mphindi zitatu, ndi yerekezerani mtundu mphamvu ya yankho. Chitsulo chokhala ndi chromium yapamwamba chimakhala ndi mtundu wakuda wobiriwira.
