20 #Q355B ndi zida zina za feteleza zapamwamba zothamanga kwambiri zopanda msoko

20 #Q355B ndi zida zina feteleza mkulu-anzanu msokonezo chitoliro

Kufotokozera Kwachidule:

Feteleza wapadera chitoliro GB6479-2000 amatanthauza msokonezo zitsulo chitoliro kwa mkulu kuthamanga zipangizo feteleza.Amagwiritsidwa ntchito kwambiri potengera kutentha kwambiri komanso mapaipi amadzimadzi othamanga kwambiri pazida za feteleza.Zida zoyimira ndi 20, 16Mn, 12CrMo, 12Cr2Mo, etc.

Chiyambi cha malonda

Mapaipi achitsulo a feteleza wamankhwala amagwiritsidwa ntchito kwambiri popanga zitsulo zapamwamba kwambiri za carbon, aloyi structural zitsulo ndi zitsulo zosapanga dzimbiri zosagwira kutentha kwapakatikati pamipope yowotchera nthunzi yothamanga kwambiri komanso pamwamba pa machubu ndipo machubu otenthetserawa amagwira ntchito kutentha kwambiri. ndi kuthamanga kwambiri, ndi machubu adzakhala oxidized ndi dzimbiri pansi zochita za mkulu-kutentha chitoliro mpweya ndi nthunzi.Chifukwa chake, machubu achitsulo amafunikira kukhala ndi mphamvu zokhalitsa, kukana kwa okosijeni wambiri, komanso kukhazikika kwadongosolo.Makalasi azitsulo omwe amagwiritsidwa ntchito ndi awa: apamwamba kwambiri a carbon structural steel grade 20G, 20MnG, 25MnG;Aloyi structural zitsulo makalasi 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc;Machubu wamba a 1Cr18Ni9 ndi 1Cr18Ni11Nb opopera kwambiri opangidwa ndi chitsulo cha dzimbiri komanso chosagwira kutentha adzayesedwa ndi hydrostatic test, flaring and flattening test m'modzi m'modzi kuwonjezera pakuwonetsetsa kapangidwe kake ka mankhwala ndi makina.Machubu apadera achitsulo a feteleza wamankhwala aziperekedwa munyengo ya kutentha.

Malo oyenerera

The chitoliro wapadera feteleza (GB6479-2000) ndi apamwamba mpweya structural zitsulo ndi aloyi chitsulo chosakanizidwa zitsulo chitoliro oyenera zida mankhwala ndi mipope ndi kutentha ntchito - 40 ~ 400 ℃ ndi ntchito kuthamanga kwa 10 ~ 30Ma.

Mkulu kuthamanga aloyi chitoliro kwa zipangizo feteleza (GB6479-2000) ndi apamwamba mpweya structural zitsulo ndi aloyi zitsulo aloyi zitsulo chitoliro oyenera zida mankhwala ndi mipope ndi kutentha ntchito - 40 ~ 400 ℃ ndi ntchito kuthamanga kwa 10 ~ 30Ma.

Chiyambi cha kupanga

(1) Njira yopangira:

①Kutentha kogwiritsa ntchito mapaipi achitsulo a feteleza ndi pansi pa 450 ℃, ndipo mapaipi apakhomo amapangidwa makamaka ndi mapaipi otentha okulungidwa kapena ozizira 10 # ndi 20 # achitsulo.

②Chitoliro chapadera chachitsulo cha feteleza nthawi zambiri chimagwiritsidwa ntchito pansi pa kutentha kwakukulu ndi kupanikizika kwakukulu, ndipo chitolirocho chimakhala ndi okosijeni ndi corrod chifukwa cha kutentha kwamphamvu kwa gasi ndi nthunzi yamadzi.Chitoliro chachitsulo chimafunika kuti chikhale ndi mphamvu zokhalitsa, makutidwe ndi okosijeni ambiri komanso kukana kwa dzimbiri, komanso kukhazikika kwadongosolo.

(2) Cholinga:

①Mapaipi achitsulo a feteleza wamankhwala amagwiritsidwa ntchito makamaka popanga mapaipi amadzi, mapaipi amadzi otentha, mapaipi otentha kwambiri a nthunzi, mapaipi otenthetsera kwambiri opangira ma boilers, mapaipi akulu ndi ang'onoang'ono a utsi ndi mapaipi a njerwa.

②Chitoliro chachitsulo chomwe chimagwiritsidwa ntchito makamaka ku feteleza chimagwiritsidwa ntchito makamaka popanga chitoliro champhamvu kwambiri, chitoliro chotenthetsera mpweya, chitoliro cha mpweya, chitoliro chachikulu cha nthunzi, ndi zina zambiri.

Chiwonetsero cha Zamalonda

Njira yoyendetsera chubu yagalasi yaukhondo:

Chubu chopanda kanthu -- kuyang'ana -- peeling -- kuyang'anira -- kutenthetsa -- kuboola -- pickling -- kupera -- mafuta ndi kuyanika mpweya -- kuwotcherera mutu - kujambula ozizira -- mankhwala yothetsera - pickling - pickling ndi passivation - kuyang'ana -- kuzizira -- kupukuta -- kudula mutu -- kuyanika mpweya -- kupukuta mkati -- kupukuta kunja -- kuyang'ana -- kuzindikira -- kuyika kwa mankhwala omalizidwa

Industrial chitoliro ndondomeko kuyenda

Chubu chopanda kanthu -- kuyang'ana -- peeling -- kuyang'anira -- kutentha -- kuboola -- pickling -- kukonza bowa -- kuthira mafuta ndi kuyanika mpweya -- kuwotcherera mutu - kujambula ozizira -- mankhwala yothetsera - pickling - pickling ndi passivation -- kuyendera
