Grey nrum hlau muaj lub peev xwm ua kom muaj zog thiab muaj kev tiv thaiv corrosion. Txawm li cas los nws yog nkig, thiab tuaj yeem nyuaj rau tshuab vim nws nyuaj rau ua kom du thiab tuaj yeem txo cov cuab yeej lub neej. Malleable hlau muaj kev poob siab zoo, yog ductile thiab yog machinable heev.
Kuj lo lus nug yog, hlau malleable txhais li cas?
Malleable hlau yog cam khwb cia raws li dawb hlau , tus qauv yog metastable carbide hauv pearlitic matrix. Los ntawm kev kho cua sov kom sov, cov txheej txheem nkig ua ntej cast yog transformed rau hauv tuaj yeem daim ntawv.
Tsis tas li ntawd, puas yog malleable hlau tib yam li hlau? Malleable hlau muaj ntau ductility uas feem ntau yuav tsum tau nyob rau hauv lub teeb industrial siv. Malleable hlau Cov yeeb nkab haum tsis zoo rau vuam (yog tias koj xav tau ib yam dab tsi rau nws). Forged fittings yog ua los ntawm A105 (carbon hlau ), stainless hlau los yog nickel alloy.
Yog li ntawd, dab tsi yog cov hlau tsis xeb tsis haum?
Cov ntsiab lus imports suav nrog tsis - malleable cam khwb cia hlau yeeb nkab fittings raws li tej yam ductile nrum . hlau yeeb nkab fittings, xws li cov uas yuav siv tau nyob rau hauv kev lig kev cai tsis - tuaj yeem kev siv yeeb nkab haum. Tsis - hlau hlau (tseem hu ua grey hlau ) yog txhais los ntawm ASTM International ("ASTM") raws li pov tseg.
Cast Iron puas tuaj yeem ua tau yooj yim?
TSIS YOG POSSIBLE los tsim cov hlau cam khwb cia hlau nyob rau hauv tej daim uas muaj loj cross sectional dimension. Qhov no yog vim, hlau muaj qhov txias txias sai heev thiab nws yuav tsis yog ua tau kom ua tiav tus nqi no ntawm qhov sib txawv ntawm qhov sib txawv hauv ib daim ntawv hlau.

Table-1: Yam Tsawg Npog Thickness rau Cast-in-Place Qhob Hom kev tsim ua vaj tse hla, hli Qhob nrum tiv thaiv thiab txuas mus tas li nrog hauv av 75 Pob zeb sib chwv nrog av lossis dej No. 19 txog No. 57 tuav 50 No. 16 bar thiab me dua 40
Dab tsi yog qhov txawv ntawm qhov ua tau zoo thiab cov khoom lag luam teb thiab cov ntsiab lus ntawm kev lag luam uas txhua qhov ua haujlwm zoo tshaj?
Lub tuam txhab muaj peev xwm ua kom tau raws li cov neeg siv khoom xav tau raws sijhawm yog hu ua Kev Ua Haujlwm Zoo, thaum ua haujlwm tau zoo yog lub tuam txhab muaj peev xwm xa khoom raws li tus neeg siv khoom xav tau nrog tsawg kawg ntawm cov khoom siv raw, kev ua haujlwm thiab tus nqi
Txoj kab uas hla ntawm cam khwb cia hlau av yeeb nkab yog dab tsi?
