ASTM A210 Qib C (ASME SA210 Qib C) yog ib lub raj hlau nruab nrab-carbon seamless uas tsim tshwj xeeb rau kev siv hauv kev tsim cov raj boiler thiab cov pa roj boiler, suav nrog cov qhov kawg kev nyab xeeb, phab ntsa cua sov thiab cov raj txhawb nqa, thiab cov raj superheater.
Qib C muaj cov khoom siv kho tshuab zoo, nrog lub zog tensile ntawm 485 MPa thiab lub zog tawm ntawm 275 MPa. Cov khoom no, nrog rau cov tshuaj lom neeg tsim nyog, ua rau ASTM A210 Qib C raj zoo rau kev siv hauv qhov kub thiab txias thiab siab thiab muaj peev xwm tiv taus cov kev ntxhov siab los ntawm kev ua haujlwm boiler.
Cov raj yuav tsum ua los ntawm cov txheej txheem seamless thiab yuav tsum yog kub-tiav lossis txias-tiav.
Hauv qab no yog daim ntawv qhia txog cov txheej txheem tsim khoom rau cov yeeb nkab hlau txias-ua tiav seamless:
Yog li qhov txawv ntawm cov yeeb nkab hlau kub-ua tiav thiab txias-ua tiav seamless thiab koj xaiv li cas?
Kub-tiav lawmCov yeeb nkab hlau tsis muaj qhov tsis sib xws yog cov yeeb nkab hlau uas raug dov lossis tho ntawm qhov kub siab thiab lwm yam txheej txheem thiab tom qab ntawd txias ncaj qha rau chav tsev kub. Cov yeeb nkab hlau hauv lub xeev no feem ntau muaj kev tawv zoo dua thiab qee lub zog, tab sis qhov zoo ntawm qhov chaw yuav tsis zoo li cov yeeb nkab hlau txias vim tias cov txheej txheem kho cua sov yuav ua rau oxidation lossis decarburization ntawm qhov chaw ntawm cov yeeb nkab hlau.
Txias-ua tiavCov yeeb nkab hlau tsis muaj seamless yog hais txog kev ua tiav zaum kawg ntawm cov yeeb nkab hlau los ntawm kev kos duab txias, dov txias, thiab lwm yam txheej txheem ntawm chav tsev kub. Cov yeeb nkab hlau txias tiav lawm muaj qhov tseeb ntawm qhov ntev dua, thiab qhov zoo ntawm qhov chaw, thiab vim tias kev ua txias tuaj yeem txhim kho lub zog thiab qhov nyuaj ntawm cov yeeb nkab hlau, cov khoom siv kho tshuab ntawm cov yeeb nkab hlau txias tiav lawm feem ntau zoo dua li cov yeeb nkab hlau kub tiav lawm. Txawm li cas los xij, qee qhov kev ntxhov siab seem yuav tsim tawm hauv cov yeeb nkab hlau thaum lub sijhawm ua haujlwm txias, uas yuav tsum tau tshem tawm los ntawm kev kho cua sov tom qab.
Cov yeeb nkab hlau kub tiav lawm tsis tas yuav kho cua sov.
Cov kav dej txias tiav lawm yuav tsum tau annealed subcritical, annealed tag nrho, lossis kho cua sov ib txwm tom qab cov txheej txheem tiav txias kawg.

Cov kev cai sim txog hluav taws xob uas tsis ua rau puas tsuaj yog raws li ASTM 450, yam khoom 26.
Kev tsim cov raj xa dej yog qhov tsim nyog rau cov raj xa dej kom ntseeg tau tias cov raj xa dej ua tau raws li qhov xav tau tshwj xeeb ntawm lub kaw lus boiler.
Thaum muab tso rau hauv lub boiler, cov raj yuav tsum sawv ntsug nthuav dav thiab beading yam tsis muaj qhov tawg lossis qhov tsis zoo. Thaum tswj hwm kom zoo, cov raj superheater yuav tsum sawv ntsug txhua qhov kev forging, vuam, thiab khoov ua haujlwm tsim nyog rau kev siv yam tsis muaj kev tsim cov qhov tsis zoo.
