Qib dab tsi yog Malleable Hlau?

Taw qhia

Malleable hlau yog ib hom cam khwb cia hlau uas tau raug tshav kub-kho kom nws ductile thiab ntau yam. Yog li ntawd, nws tuaj yeem siv rau ntau yam kev siv, los ntawm cov khoom siv hauv tsev mus rau cov khoom siv hauv tsev. Thaum nws los txog rau qib malleable hlau, muaj ntau yam uas tuaj yeem cuam tshuam rau nws qhov zoo thiab kev ua haujlwm. Hauv tsab xov xwm no, peb yuav tshawb xyuas cov qib malleable hlau yog dab tsi thiab cov yam ntxwv uas yuav tsum tau xav txog thaum xaiv cov hlau malleable rau koj cov haujlwm.

Malleable Iron yog dab tsi?

Malleable hlau yog ib hom cam khwb cia hlau uas muaj cov ntsiab lus qis dua li cov cam khwb cia hlau. Qhov no ua rau nws yooj yim dua, los yog malleable, uas txhais tau hais tias nws tuaj yeem tsim tau yooj yim lossis zoo li tsis muaj kev tawg. Malleable hlau yog tsim los ntawm thawj zaug tshem tawm impurities los ntawm cam khwb cia hlau los ntawm cov txheej txheem refining. Cov hlau yog tom qab ntawd kub-kho, feem ntau ntawm qhov kub ntawm ib ncig ntawm 1,550 degrees Fahrenheit. Cov txheej txheem no, hu ua annealing, ua rau cov pa roj carbon ntau hauv cov hlau tsim rau hauv graphite flakes, uas pab ua kom cov hlau ntau dua.

Qib twg yog Malleable Hlau?

Malleable hlau tuaj yeem muab qhab nia raws li ntau yam, suav nrog nws lub zog tensile, yield zog, thiab elongation. Tensile lub zog yog hais txog tus nqi ntawm lub zog uas yuav tsum tau rub lub hlau sib nrug, thaum lub zog tawm los yog hais txog tus nqi ntawm lub zog uas yuav tsum tau ua kom deform cov hlau mus tas li. Elongation yog ib qho kev ntsuas ntawm ntau npaum li cas cov hlau tuaj yeem ncav cuag yam tsis muaj kev tawg.

Feem ntau, cov qib siab dua ntawm cov hlau tsis muaj hlau yuav muaj zog tensile ntau dua thiab cov txiaj ntsig zoo thiab ntau dua elongation. Qib ntawm malleable hlau feem ntau raug xaiv raws li ASTM International kev faib tawm, uas muab cov ntawv qib raws li cov hlau cov khoom. Qib B malleable hlau yog qhov ntau tshaj plaws thiab feem ntau muaj lub zog tensile ntawm ib ncig ntawm 60, 000 phaus ib square inch (psi) thiab lub zog tawm ntawm ib ncig ntawm 40, 000 psi.

Cov qib siab dua, xws li Qib C, feem ntau yuav muaj zog tensile ntau dua thiab cov txiaj ntsig tau zoo thiab muaj zog elongation ntau dua. Piv txwv li, Qib C malleable hlau yuav muaj lub zog tensile ntawm ib ncig ntawm 70, 000 psi thiab lub zog tawm ntawm ib ncig ntawm 50, 000 psi.

Tej yam yuav tsum tau xav txog thaum xaiv Malleable Hlau

Thaum xaiv malleable hlau rau koj tej yaam num, muaj ntau yam los xav txog ntxiv rau nws qib. Cov no suav nrog daim ntawv thov, ib puag ncig uas yuav siv cov hlau, thiab cov kev cai tshwj xeeb lossis cov cai tswj kev siv hlau.

Daim ntawv thov:

Thawj qhov yuav tsum tau xav txog thaum xaiv cov hlau tsis muaj hlau yog daim ntawv thov uas nws yuav siv. Malleable hlau feem ntau yog siv rau hauv kev siv xws li kev tsim cov yeeb nkab fittings, industrial machinery, thiab automotive qhov chaw. Nws kuj yog siv rau hauv ntau yam khoom siv hauv tsev, xws li cov khoom siv teeb pom kev zoo thiab rooj tog zaum. Nyob ntawm daim ntawv thov, qib sib txawv ntawm malleable hlau yuav tsim nyog dua. Piv txwv li, cov qib siab dua yuav xav tau rau cov ntawv thov uas xav tau lub zog ntau dua lossis tsis kam hnav thiab tsim kua muag.

Ib puag ncig:

Qhov thib ob yuav tsum xav txog yog ib puag ncig uas yuav siv tau cov hlau malleable. Piv txwv li, yog tias cov hlau yuav raug siv nyob rau hauv ib puag ncig corrosive, xws li hauv dej hiav txwv, tej zaum yuav tsim nyog xaiv cov qib ntawm cov hlau uas muaj cov hlau tsis zoo, xws li Qib A. Ib yam li, yog tias cov hlau yuav raug siab. qhov kub thiab txias, xws li nyob rau hauv lub cav thaiv, nws yuav tsum tau xaiv cov qib nrog lub siab melting point, xws li Qib D.

Kev cai:

Thaum kawg, nws yog ib qho tseem ceeb uas yuav tau txiav txim siab txog cov cai tswj kev siv cov hlau tsis zoo hauv koj daim ntawv thov. Piv txwv li, qee daim ntawv thov yuav xav tau ua raws li cov qauv kev nyab xeeb lossis cov lej hauv tsev. Tsis tas li ntawd, qee lub tebchaws yuav muaj cov cai tswj hwm kev siv cov hlau tsis muaj hlau lossis yuav tsum tau siv qee cov qib los siv rau hauv qee yam kev siv.

Xaus

Malleable hlau yog ntau yam thiab ductile daim ntawv ntawm cam khwb cia hlau uas tau raug tshav kub-kho kom nws ntau malleable. Nws tuaj yeem muab qhab nia raws li ntau yam, suav nrog lub zog tensile, lub zog tawm los, thiab elongation. Thaum xaiv malleable hlau rau koj tej yaam num, nws yog ib qho tseem ceeb uas yuav tau xav txog daim ntawv thov, ib puag ncig nyob rau hauv uas cov hlau yuav siv, thiab tej kev cai tswj nws siv. Los ntawm kev noj cov khoom no rau hauv tus account, koj tuaj yeem xyuas kom meej tias koj xaiv cov qib zoo ntawm malleable hlau rau koj xav tau.
