Pearlite Heat-Resistant 12CR 1movg High Pressure Alloy Tube
Matrix ndi chitsulo chochepa cha alloy chopanda kutentha chokhala ndi pearlite kapena bainite.Pali makamaka chromium-molybdenum ndi chromium-molybdenum-vanadium mndandanda.Pambuyo pake, mitundu ingapo (monga chromium, tungsten, molybdenum, vanadium, titaniyamu, boron, ndi zina zotero) yapangidwa, ndipo kulimba ndi kutentha kwa chitsulo kwawonjezeka pang'onopang'ono.Koma nthawi zambiri kuchuluka kwa zinthu zophatikizika kumakhala pafupifupi 5%, ndipo kapangidwe kake kamakhala ndi chitsulo cha bainitic kuwonjezera pa pearlite.Chitsulo chamtunduwu chimakhala ndi mphamvu yabwino yokwera kutentha komanso kugwira ntchito pa 450 ~ 620 ℃, ndipo chimakhala ndi matenthedwe abwino, otsika kwambiri komanso mtengo wotsika.Amagwiritsidwa ntchito kwambiri popanga zida zosiyanasiyana zosagwira kutentha za 450 ~ 620 ℃.Monga mapaipi achitsulo opopera opangira magetsi, ma turbine turbine impellers, ma rotor, fasteners, zotengera zopatsirana kwambiri zoyenga mafuta ndi mafakitale amafuta, ma boiler otentha otaya zinyalala, machubu otenthetsera ng'anjo ndi machubu osinthira kutentha, ndi zina zambiri.
[1] Chitsulo cha mapaipi achitsulo otsika aloyi osagwira kutentha.
Amagwiritsidwa ntchito makamaka ngati makoma amadzi opopera, ma superheaters, reheaters, economizers, mahedifoni ndi mapaipi a nthunzi, komanso machubu osinthanitsa ndi kutentha kwa petrochemical ndi nyukiliya.Zinthuzo zimafunika kuti zikhale ndi malire okwera kwambiri, mphamvu zokhalitsa komanso pulasitiki yokhalitsa, kukana kwa okosijeni wabwino ndi kukana kwa dzimbiri, kukhazikika kwadongosolo kokwanira komanso kutsekemera kwabwino komanso kutentha ndi kuzizira.Moyo wautumiki wopangidwa umafikira maola 200,000.Mitundu yayikulu ku China ndi 12CrMo, 15CrMo, 12Cr2Mo, 12CrlMoVG high-pressure alloy chubu, ndi 12Cr2MoWVTiB, omwe amagwiritsidwa ntchito pa 480 ~ 620 ℃.Normalizing ndi kutentha nthawi zambiri amagwiritsidwa ntchito pochiza kutentha.
[2] Chitsulo cha mbale zotengera zothamanga kwambiri.
M'makampani a petrochemical, malasha gasification, magetsi a nyukiliya ndi malo opangira magetsi, mbale zachitsulo zotsika alloy zosagwira kutentha zimagwiritsidwa ntchito kwambiri popanga zombo zokakamiza.Mitundu yayikulu ku China ndi mapaipi a 15CrMoG othamanga kwambiri (1.25Cr-O.5Mo), 12Cr2Mo (2.25Cr-1Mo) ndi 12Cr1MoV, ndi zina zambiri. (25-150 mm).), chifukwa zida zakhala zikugwira ntchito pansi pa kutentha kwakukulu, kuthamanga kwambiri ndi kukana kwa haidrojeni kwa nthawi yaitali, poganizira kupewa kutsekemera kwa 475 ° C, zinthuzo zimafunika kuti zikhale zoyera kwambiri, ndi sulfure ndi phosphorous. akuyembekezeka kukhala osachepera 0.01% ndi malata otsika kwambiri, Zinthu zowopsa monga antimoni ndi arsenic zimafunikira kusungunula kwa ng'anjo yamagetsi ndi kuyengedwa kwakunja.
[3]Chitsulo cha zomangira.
Chitsulo cha Fastener ndi chinthu chofunikira kwambiri chomwe chimagwira ntchito polumikizana ndi ma turbines a nthunzi, ma boilers ndi zida zina zokhala ndi mphamvu zambiri.Zimafunika malire okolola okwanira, kukhazikika kwapamwamba, kukhazikika kwabwino kwa pulasitiki komanso kukhudzidwa kwazing'ono kwa nthawi yaitali.Kukana kwa oxidation ndi ntchito yabwino yodula.Mitundu yayikulu ku China ndi 25Cr2Mo, 25Cr2MoV, 25Cr2Mo1V, 20Cr1M01VNbTiB, etc., yomwe ingagwiritsidwe ntchito pamitundu ya 500 ~ 570 ℃ motsatana.Izi nthawi zambiri zimagwiritsidwa ntchito pambuyo pozimitsa ndi kutentha.
[4] Chitsulo cha rotor (spindle, impeller).
Shaft yayikulu, chowongolera komanso cholumikizira cholumikizira ndi chimodzi mwazinthu zazikulu za turbine ya nthunzi.Zomwe zimafunikira kuti zikhale ndi makina abwino ophatikizana, kulimba kwa fracture, kukana kwamphamvu kwambiri komanso kulimba mtima, komanso kukana kutopa kwamafuta.Mitundu yomwe imagwiritsidwa ntchito nthawi zambiri ya spindle ndi impeller ku China ndi 35CrMo, 35CrMoV, 27Cr2Mo1V, 12Cr3MoWV, ndi zina zotere. Makina ozungulira mpweya amapangidwa kuchokera kuzitsulo za 20Cr3MoWV.Kugwiritsa ntchito kuzizira ndi kutentha.Pazinthu zazikuluzikulu monga ma rotor opangidwa ndi ma impellers, kuti asungunuke kwathunthu vanadium carbide ndikuwongolera pulasitiki ndi kulimba, kuwongolera kokhazikika kumatha kuchitidwa musanazimitse, kapena njira yochizira kutentha yawiri yokhazikika komanso yotentha ingagwiritsidwe ntchito.
[5] 1Cr5Mo ndi Cr6SiMo zitsulo.
Magiredi awiriwa ali ndi zinthu zapamwamba kwambiri za alloying mu chitsulo chosamva kutentha kwa pearlitic.Amakhala ndi kukana kwabwino kwa kutentha komanso kukana kwa dzimbiri mu petroleum media.Amagwiritsidwa ntchito kwambiri popanga mapaipi ndi zombo za zida zopangira mafuta a petroleum, machubu otenthetsera ng'anjo ndi Zosinthana zotentha, ndi zina zambiri, zimagwiritsidwanso ntchito ngati kupondaponda kotentha, mapampu amafuta, mavavu, ma boiler ndi mbali zina.Nthawi zambiri kutentha kwa ntchito kumakhala pansi pa 650 ℃.Popeza chitsulo ichi ndi chitsulo chowumitsidwa ndi mpweya, msoko wowotcherera umakhala ndi kuuma kwakukulu komanso pulasitiki yosauka, choncho uyenera kuziziritsidwa pang'onopang'ono ndi kutsekedwa pambuyo kuwotcherera.
Kugudubuzika kotentha (chubu chachitsulo chosakanizidwa chotuluka): chubu chozungulira → kutenthetsa → kuboola → kugudubuza mipukutu itatu, kugudubuza mosalekeza kapena kutulutsa → kuchotsa machubu → kukula (kapena kuchepetsa) → kuziziritsa → chubu cha billet → kuwongola → Kuyesa kuthamanga kwamadzi (kapena cholakwika kuzindikira) → chizindikiro → malo osungira.
Chitoliro chozizira chokoka (chogudubuzika) chosasunthika chachitsulo: chubu chozungulira → kutenthetsa → kuboola → kuboola → mutu → kupukuta → pickling → kudzola mafuta (kubisala zamkuwa) → zojambula zozizira zambiri (zozizira) → chubu cha billet → chithandizo cha kutentha → kuwongola → Kuyesa kuthamanga kwa madzi (kuzindikira zolakwika) → chongani → malo osungira.
