Chitoliro chosapanga dzimbiri chokongoletsera chitsulo
Chitoliro chosapanga dzimbiri chokongoletsera chimatchedwanso chitoliro chachitsulo chosapanga dzimbiri chotchedwa welded chitoliro chachifupi.Kawirikawiri, chitsulo kapena chitsulo Mzere ndi welded mu zitsulo chitoliro pambuyo crimped ndi kupangidwa ndi unit ndi nkhungu.Njira yopanga welded zitsulo chitoliro ndi yosavuta, dzuwa kupanga ndi mkulu, pali mitundu yambiri ndi specifications, ndi zipangizo mtengo waung'ono, koma mphamvu ambiri ndi m'munsi kuposa chitoliro chosasokonezeka zitsulo.
Pali mitundu yambiri ya mapaipi achitsulo chosapanga dzimbiri, koma amagwiritsidwa ntchito makamaka pazolinga izi:
1,Gulu la mipope yachitsulo chosapanga dzimbiri
1. Gulu ndi njira yopanga:
(1) Chitoliro chopanda msoko - chitoliro chozizira, chitoliro chotuluka, chitoliro chozizira.
(2) Chitoliro chowotcherera:
(a) Malinga ndi gulu la ndondomeko - chitoliro chotchinga cha gasi, chitoliro chowotcherera cha arc, chitoliro chowotcherera (mafupipafupi, otsika).
(b) Imagawidwa mu chitoliro chowongoka chowongoka ndi chitoliro chozungulira mozungulira molingana ndi weld.
2. Gulu molingana ndi mawonekedwe a gawo: (1) chitoliro chachitsulo chozungulira;(2) chubu lamakona anayi.
3. Gulu ndi makulidwe a khoma - chitoliro chochepa kwambiri chachitsulo, chitoliro chachitsulo chokhuthala
4. Zodziwika ndi ntchito: (1) Mipope yapachiweniweni imagawidwa m'mapaipi ozungulira, mapaipi amakona anayi ndi mapaipi amaluwa, omwe amagwiritsidwa ntchito pokongoletsa, kumanga, kupanga, ndi zina zotero;
(2) Industrial chitoliro: zitsulo chitoliro kwa mipope mafakitale, zitsulo chitoliro kwa mapaipi ambiri (madzi akumwa chitoliro), makina dongosolo / madzi yobereka chitoliro, kukatentha kutentha kuwombola chitoliro, chakudya ukhondo chitoliro, etc. Nthawi zambiri amagwiritsidwa ntchito m'madera osiyanasiyana a mafakitale. , monga petrochemical, pepala, mphamvu nyukiliya, chakudya, chakumwa, mankhwala ndi mafakitale ena ndi zofunika mkulu wa sing'anga madzimadzi.
2,Chitoliro chopanda chitsulo
Chitoliro chosapanga dzimbiri chosapanga dzimbiri ndi mtundu wachitsulo chachitali chokhala ndi gawo la dzenje ndipo palibe mfundo zozungulira.
1. Njira yopangira ndi kutuluka kwa chitoliro chopanda chitsulo:
Kusungunula>ingot>kugudubuza zitsulo>kucheka>kupeta>kubaya>annealing>kudulira>kudulira phulusa>kujambula kuzizira>kudula mutu>kupikha>kusunga
2. Mawonekedwe a chitoliro chachitsulo chosasunthika:
Sikovuta kuwona kuchokera pamayendedwe omwe ali pamwambapa: choyamba, makulidwe a khoma la mankhwalawo, amakhalanso okwera mtengo komanso othandiza.Kuchepa kwa makulidwe a khoma, ndiye kuti mtengo wokonza udzakhala wapamwamba kwambiri;Kachiwiri, ndondomeko ya mankhwala imatsimikizira zofooka zake.Nthawi zambiri, kulondola kwa chitoliro chopanda chitsulo ndi chochepa: makulidwe a khoma, kuwala kochepa kwa pamwamba ndi kunja kwa chitoliro, mtengo wamtengo wapatali, ndipo pali maenje ndi mawanga akuda pamtunda mkati ndi kunja kwa chitoliro, zomwe zimakhala zovuta kuziyika. chotsani;Chachitatu, kuzindikira kwake ndi mawonekedwe ake kuyenera kukonzedwa popanda intaneti.Choncho, ali ndi ubwino wake kuthamanga, mkulu mphamvu ndi makina kapangidwe zipangizo.
3,Welded zitsulo chitoliro

2. Mbali welded zitsulo chitoliro:
Sizovuta kuwona kuchokera kumayendedwe apamwambawa: choyamba, mankhwalawa amapangidwa mosalekeza komanso pa intaneti.Kukhuthala kwa khoma kumachulukirachulukira ndalama zogulira zida ndi zida zowotcherera, komanso kuchepa kwachuma komanso kothandiza.The woonda khoma, m'munsi ake athandizira-linanena bungwe chiŵerengero adzakhala;Kachiwiri, ndondomeko ya mankhwala imatsimikizira ubwino ndi kuipa kwake.Nthawi zambiri, welded zitsulo chitoliro ali mwatsatanetsatane mkulu, yunifolomu khoma makulidwe, mkulu mkati ndi kunja pamwamba kuwala kwa zosapanga dzimbiri zitsulo chitoliro chitoliro (chitsulo chitoliro pamwamba kuwala anatsimikiza ndi pamwamba kalasi ya mbale zitsulo), ndipo akhoza mopanda malire kakulidwe.Choncho, imaphatikizapo chuma chake ndi kukongola kwake pogwiritsira ntchito madzi othamanga kwambiri, otsika kwambiri.
Pali chlorine ion m'malo ogwiritsidwa ntchito.Ma ayoni a klorini alipo ambiri, monga mchere, thukuta, madzi a m’nyanja, mphepo yamkuntho, nthaka, ndi zina zotero. Chitsulo chosapanga dzimbiri chimawononga msanga pamaso pa ayoni wa chloride, ngakhale kuposa chitsulo chochepa kwambiri cha carbon.Choncho, pali zofunikira pa malo ogwiritsira ntchito zitsulo zosapanga dzimbiri, ndipo m'pofunika kupukuta nthawi zonse kuti muchotse fumbi ndikulisunga loyera ndi louma.
316 ndi 317 zitsulo zosapanga dzimbiri (onani m'munsimu za zitsulo zosapanga dzimbiri 317) ndi molybdenum yokhala ndi zitsulo zosapanga dzimbiri.Zomwe zili mu molybdenum mu 317 zitsulo zosapanga dzimbiri ndizokwera pang'ono kuposa zomwe zili muzitsulo zosapanga dzimbiri 316.Chifukwa cha molybdenum muzitsulo, ntchito yonse yachitsulo ichi ndi yabwino kuposa 310 ndi 304 zitsulo zosapanga dzimbiri.Pansi pa kutentha kwambiri, pamene kuchuluka kwa sulfuric acid kumakhala kochepa kuposa 15% ndipamwamba kuposa 85%, 316 zitsulo zosapanga dzimbiri zimakhala ndi ntchito zosiyanasiyana.Chitsulo chosapanga dzimbiri cha 316 chimakhalanso ndi kukana kwa dzimbiri kwa chloride, chifukwa chake chimagwiritsidwa ntchito m'malo am'madzi.Ndi chitukuko cha chuma cha chikhalidwe cha anthu, kugwiritsa ntchito chitoliro chachitsulo chosapanga dzimbiri chakhalanso chodziwika kwambiri.Idzabweretsa kusintha kwatsopano m'magawo onse.

316 chitoliro chosapanga dzimbiri
Zitsulo zomwe zimagwiritsidwa ntchito pamafuta, mankhwala, zamankhwala, chakudya ndi mafakitale opepuka
316 zosapanga dzimbiri chitoliro ndi mtundu wa dzenje yaitali kuzungulira zitsulo, amene chimagwiritsidwa ntchito mafuta, mankhwala, mankhwala, chakudya, makampani kuwala, zida makina ndi mapaipi kufala mafakitale ndi zigawo zikuluzikulu makina structural.Kuphatikiza apo, mphamvu yopindika ndi yopindika ikafanana, kulemera kwake kumakhala kopepuka, kotero kumagwiritsidwanso ntchito kwambiri popanga zida zamakina ndi zomangamanga.Amagwiritsidwanso ntchito popanga zida zosiyanasiyana wamba, migolo, zipolopolo, ndi zina.
Pazipita mpweya zili 316 zitsulo zosapanga dzimbiri chitoliro ndi 0.03, amene angagwiritsidwe ntchito ntchito pamene annealing saloledwa pambuyo kuwotcherera ndi kukana dzimbiri pakufunika.
316 ndi 317 zitsulo zosapanga dzimbiri (onani m'munsimu za zitsulo zosapanga dzimbiri 317) ndi molybdenum yokhala ndi zitsulo zosapanga dzimbiri.
Ntchito yonse yachitsulo ichi ndi yabwino kuposa 310 ndi 304 zitsulo zosapanga dzimbiri.Pa kutentha kwakukulu, pamene kuchuluka kwa sulfuric acid kumakhala kotsika kuposa 15% ndipamwamba kuposa 85%, 316 zitsulo zosapanga dzimbiri zimakhala ndi ntchito zosiyanasiyana.
316 zitsulo zosapanga dzimbiri, zomwe zimadziwikanso kuti 00Cr17Ni14Mo2, kukana kwa dzimbiri:
Kukana kwa dzimbiri ndikwabwino kuposa 304 chitsulo chosapanga dzimbiri, ndipo kumakhala ndi kukana bwino kwa dzimbiri popanga zamkati ndi pepala.
Carbide mpweya kukana 316 zitsulo zosapanga dzimbiri ndi bwino kuposa 304 zitsulo zosapanga dzimbiri, ndipo pamwamba kutentha osiyanasiyana angagwiritsidwe ntchito.
Mitundu: 316 zitsulo zosapanga dzimbiri, machubu 316 osapanga dzimbiri owala, machubu 316 okongoletsera zitsulo zosapanga dzimbiri, machubu 316 achitsulo chosapanga dzimbiri, machubu 316 achitsulo chosapanga dzimbiri, machubu 304 achitsulo chosapanga dzimbiri.
Pazipita mpweya zili 316L zitsulo zosapanga dzimbiri chitoliro ndi 0.03, amene angagwiritsidwe ntchito ntchito pamene annealing saloledwa pambuyo kuwotcherera ndi kukana dzimbiri pakufunika.
