321 Machubu Opanda Zitsulo
Kufotokozera
321 chitsulo chosapanga dzimbiri chitoliro ndi chitoliro chachitsulo chopangidwa ndi 321 chitsulo chosapanga dzimbiri.
1:321 chitoliro chosapanga dzimbiri.Chitoliro chosasunthika chachitsulo (GB14976-2002) chimagwiritsidwa ntchito popanga mapaipi otentha kwambiri, mapaipi amadzi otentha ndi ma boiler opangira ma locomotive amitundu yosiyanasiyana yama boilers otsika komanso apakatikati, mapaipi akuluakulu a utsi, mapaipi ang'onoang'ono a utsi ndi mapaipi a njerwa.Chitsulo chapamwamba cha carbon structural chotenthetsera komanso chozizira (chogudubuza) mapaipi achitsulo opanda msoko.
2:321 chitoliro chachitsulo chosapanga dzimbiri: chomwe chimagwiritsidwa ntchito kwambiri popanga zitsulo zapamwamba kwambiri za carbon structural steel, alloy structural chitsulo ndi chitsulo chosapanga dzimbiri chosagwira chitsulo chosapanga dzimbiri chopanda chitsulo chosapanga dzimbiri cha mapaipi opopera a nthunzi okhala ndi kuthamanga kwambiri komanso pamwamba.Mipope ya boiler iyi nthawi zambiri imakhala ndi kutentha kwambiri komanso kuthamanga kwambiri.Ntchito, chitoliro adzakhalanso oxidize ndi dzimbiri pansi zochita za mkulu kutentha chitoliro mpweya ndi nthunzi madzi, kotero chitoliro zitsulo chofunika kukhala mkulu okhalitsa mphamvu, mkulu makutidwe ndi okosijeni kukana, ndi bwino bungwe bata.
3: 321 zitsulo zosapanga dzimbiri chubu utenga chitsulo nambala: 304321 316 317 310, etc.
4: Aloyi structural zitsulo mapaipi ndi makalasi zitsulo 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc.;zitsulo zosapanga dzimbiri komanso zosagwira kutentha zomwe zimagwiritsidwa ntchito kwambiri 1Cr18Ni9, 1Cr18Ni11Nb machubu otenthetsera kwambiri, kuwonjezera pakuwonetsetsa kuti mankhwala amapangidwa ndi zinthu zamakina, ayenera kukakamizidwa ndi madzi chimodzi ndi chimodzi Kuti ayesedwe, kuyezetsa kowotcha ndi kuwongolera kumafunika.
5: 321 mapaipi azitsulo zosapanga dzimbiri amaperekedwa m'malo otenthedwa.Komanso, pali zofunika zina za microstructure, kukula kwa tirigu ndi decarburization wosanjikiza wa chitoliro yomalizidwa zitsulo.Mipope yachitsulo yopanda msoko pobowola geological ndi kuwongolera pobowola mafuta;zitsulo zobowolera zimagwiritsidwa ntchito pofufuza momwe miyala yapansi panthaka, madzi apansi panthaka, mafuta, gasi ndi minerals amagwirira ntchito.
Kugwiritsa ntchito mafuta ndi gasi sikungasiyanitsidwe ndi zitsime zoboola.Mipope yachitsulo yosasunthika pobowola mafuta pakuwongolera pobowola geological ndi zida zazikulu zobowola, makamaka kuphatikiza chitoliro chakunja, chitoliro chamkati chamkati, casing, chitoliro chobowola ndi zina zotero.Chifukwa pobowola chitoliro ayenera kulowa mwakuya mapangidwe makilomita angapo, 1cr5mo aloyi chitoliro.
6: Mikhalidwe yogwirira ntchito ndi yovuta kwambiri.Chitoliro chobowola chimakhala ndi kupsinjika monga kupsinjika, kupsinjika, kupindika, kugwedezeka ndi kukhudzidwa kosakwanira, komanso kumayikidwa pamatope ndi miyala.Choncho, chitolirocho chiyenera kukhala ndi mphamvu zokwanira, kuuma, kuvala kukana ndi kulimba kwa Impact, chitsulo chomwe chimagwiritsidwa ntchito pazitsulo zachitsulo chikuyimiridwa ndi "DZ" (chithunzi cha geological Chinese Pinyin) kuphatikizapo nambala imodzi kuti iwonetsere zokolola zachitsulo.Zomwe zimagwiritsidwa ntchito kwambiri ndizitsulo ndi 45MnB ndi 50Mn za DZ45;40Mn2 ndi 40Mn2Si ya DZ50;40Mn2Mo ndi 40MnVB ya DZ55;40MnMoB ya DZ60, 27MnMoVB ya DZ65.Mapaipi achitsulo amaperekedwa m'malo otenthedwa ndi kutentha.
Kusiyana pakati pa 321 chitsulo chosapanga dzimbiri ndi 304 chitsulo chosapanga dzimbiri
321 chitsulo chosapanga dzimbiri kwenikweni ndi mtundu wosinthidwa wa 304 chitsulo chosapanga dzimbiri.Kusiyana kwakukulu pakati pa awiriwa ndi kuwonjezeka kasanu kwa carbon chifukwa cha kuwonjezera kwa titaniyamu.Kuphatikiza kwa titaniyamu kumathandiza kupewa mvula ya carbide panthawi yowotcherera komanso kutentha kwakukulu.
Mosasamala kanthu za kuwonjezera kodabwitsa kwa titaniyamu, 321 ikadali ndi zinthu zambiri zomwe zimapanga zitsulo zosapanga dzimbiri mu mndandanda wa 300 kukhala wamkulu kwambiri.Zomwe zimagwiritsidwa ntchito nthawi zambiri pazitsulo zosapanga dzimbiri 321 ndizophatikizira, makina otulutsa magalimoto olemera kwambiri, zotchingira zozimitsa moto, ma stack liners, zida zandege, ndi zida zina zotentha kwambiri.
