China ASTM A53 Gr.B Chitoliro Chachitsulo Chotentha Chopanda Mpweya Chopanda Msokonezo
Kufotokozera Kwachidule:
Chitoliro cha Chitsulo cha Alloy ichi chokhala ndi 12cr1MOV Material ndi chitoliro chachitsulo chosasunthika chomwe chitha kugwiritsidwa ntchito popanga mafuta, mankhwala, mphamvu yamagetsi ndi boiler.Iwo ali makhalidwe a kukana kuzizira, kukana kutentha ndi kukana dzimbiri.12Cr1MoV ndi mtundu wa chitoliro aloyi.Cholinga chachikulu ndikupanga zigawo zachitsulo mu boiler.
Potsatira mfundo ya "ubwino, ntchito, magwiridwe antchito ndi kukula", talandira zikhulupiliro ndi matamando kuchokera kwa kasitomala wapakhomo ndi wakunja ku China ASTM A53 Gr.B Chitoliro Chachitsulo Chopanda Mpweya Chotentha cha Carbon, Kuti mudziwe zambiri kapena mungakhale ndi funso lokhudza katundu wathu, onetsetsani kuti musazengereze kutiimbira foni.
Kutsatira mfundo ya "ubwino, ntchito, magwiridwe antchito ndi kukula", tapeza zikhulupiliro ndi matamando kuchokera kwa kasitomala wapakhomo ndi wapadziko lonse lapansi.Chitoliro cha Chitsulo cha China ndi Chitoliro cha Carbon, Tikukulitsa gawo lathu la msika wapadziko lonse lapansi kutengera zinthu zabwino, ntchito zabwino kwambiri, mtengo wokwanira komanso kutumiza munthawi yake.Chonde titumizireni nthawi iliyonse kuti mudziwe zambiri.
Kutentha kwautumiki ndi 580 ℃, ndipo mbale yachitsulo imayenera kukhala ndi mphamvu yopirira kwambiri kutentha.Chitsulo chachitsulo chimaperekedwa mu chikhalidwe chokhazikika komanso chosasunthika.12Cr1MoVG alloy chitoliro chimakhazikitsidwa ndi chitsulo chapamwamba kwambiri cha carbon structural, ndipo chinthu chimodzi kapena zingapo za alloy zimawonjezedwa moyenera kuti zithandizire kukonza makina, kulimba komanso kulimba kwachitsulo.Zogulitsa zopangidwa ndi zitsulo zoterezi nthawi zambiri zimafuna chithandizo cha kutentha (normalizing kapena quenching ndi tempering);Zigawo ndi zigawo zomwe zimapangidwa ndi iwo nthawi zambiri zimafunika kuzimitsidwa ndikuwotcha kapena mankhwala opangira mankhwala (carburizing, nitriding, etc.), kuzimitsa pamwamba kapena kuzimitsa pafupipafupi musanagwiritse ntchito.Chifukwa chake, molingana ndi mitundu yosiyanasiyana yamankhwala (makamaka okhutira ndi kaboni), njira zochizira kutentha ndi ntchito, zitsulo zoterezi zimatha kugawidwa m'magulu opangidwa ndi carburized, Kuzimitsidwa ndi kupsya mtima ndi nitrided.
Choyamba, itha kukhala 100% yobwezeretsedwanso, yopulumutsa mphamvu komanso kuteteza chilengedwe.
Chachiwiri, ili ndi pulasitiki yapamwamba kwambiri ndipo imatha kugwiritsidwa ntchito popanga ndi kukonza yachiwiri.
Chachitatu, ali ndi madutsidwe abwino matenthedwe ndi kutentha kwambiri zokwawa mphamvu.
Chachinayi, imakhala ndi kukana kwa okosijeni wabwino komanso kukana dzimbiri.
Chachisanu, ili ndi ntchito yabwino yozizira komanso yotentha.
12Cr1MoVG ndi mtundu wa chromium molybdenum aloyi zitsulo chitoliro, imene waukulu zigawo zikuluzikulu mankhwala ndi mpweya 0.08-0.15, pakachitsulo 0.17-0.37, manganese 0.40-0.70, phosphorous osapitirira 0.035, sulfure osati kuposa 0.chro035,0. molybdenum 0.25-0.35, alum 0.15-0.30, etc.
Choyamba, amagwiritsidwa ntchito kwambiri popanga machubu a alloy apamwamba kwambiri otenthetsera ma boiler amadzi okhala ndi kuthamanga kwambiri komanso kupitilira apo.
Chachiwiri, amagwiritsidwa ntchito kwambiri m'malo otenthetsera, ma header ndi ma ducts akuluakulu am'nyumba amphamvu kwambiri, kuthamanga kwambiri komanso ma boilers a subcritical power station.
Chachitatu, mapaipi akulu akulu amagwiritsidwa ntchito ngati mitu ndi Main Steam Conduits okhala ndi magawo a nthunzi pansi pa 565 ℃.
Choyamba, kutentha kugubuduza (extrusion seamless chitsulo chitoliro) otaya ndondomeko:
Round chubu billet → kutentha → kuboola → mipukutu itatu yopingasa, kupindika mosalekeza kapena kutulutsa → kuvula chitoliro → kukula (kapena kuchepetsa) → kuzizira → billet → kuwongola → kuyesa kwa hydrostatic (kapena kuzindikira zolakwika) → kuyika chizindikiro → malo osungira.
Chachiwiri, kujambula kozizira (kugubuduza) kopanda chitsulo chopanda chitoliro kumayenda:
Round chubu billet → kutenthetsa → kuboola → mutu → kubowoleza → pickling → zokutira mafuta (chophimba chamkuwa) → zojambula zambiri zozizira (zozizira) → chubu cha billet → chithandizo cha kutentha → kuwongola → kuyesa kwa hydrostatic (kapena kuzindikira zolakwika) → chizindikiro → malo osungira.

Potsatira mfundo ya "ubwino, ntchito, kuchita bwino komanso kukula", talandira zikhulupiliro ndi matamando kuchokera kwa makasitomala apakhomo ndi akunja aku China STM A53 Gr.B Chitoliro Chachitsulo Chopanda Mpweya Chotentha cha Carbon, Kuti mudziwe zambiri kapena mungakhale ndi funso lokhudza katundu wathu, onetsetsani kuti musazengereze kutiimbira foni.
Chitoliro cha Chitsulo cha China ndi Chitoliro cha Carbon, Tikukulitsa gawo lathu la msika wapadziko lonse lapansi kutengera zinthu zabwino, ntchito zabwino kwambiri, mtengo wokwanira komanso kutumiza munthawi yake.Chonde titumizireni nthawi iliyonse kuti mudziwe zambiri.
