Dab tsi yog qhov zoo ntawm ductile casting es tsis txhob steel casting

Nyob rau hauv 1949 raws li ib tug hloov rau steel casting nodular casting tshwm sim, tab sis tsis xav hais tias nodular casting raws li ib tug hloov rau steel casting, nws cov ntsiab lus carbon yuav ua tau siab tshaj steel casting, qhov no sphere txhim kho ua nodular casting tshaj cam khwb cia hlau thiab hlau muaj ntau. zoo heev ntawm lub cev. Ntxiv mus, nws yog precisely vim hais tias ntawm no spherical microstructure ntawm carbon uas ductile casting muaj zoo ductility thiab cuam tshuam tsis kam, yog li tag nrho cov siab loaded qhov chaw ntawm Nibco ductile casting yog tiav los ntawm lub ferritizing annealing voj voog.

Lub zog ntawm cov hlau castings yog tsawg li 40k thiab cov yield zog ntawm steel castings tsuas yog 36k, thiab lub zog ntawm ductile castings thiab cam khwb cia hlau yog piv rau ductile castings nrog ntau zog yield zog. Kev tiv thaiv corrosion thiab oxidation tsis kam ntawm ductile casting yog ntau tshaj li ntawm cov cam khwb cia hlau. Vim lub spheroidal graphite microstructure ntawm spheroidal graphite castings, lub peev xwm ntawm spheroidal graphite castings tsis muaj zog, uas yog zoo dua li cov cam khwb cia hlau, yog li nws yog ntau conducive rau txo kev ntxhov siab. Ib qho laj thawj tseem ceeb rau kev xaiv cov khoom siv hluav taws xob yog qhov ductile castings raug nqi tsawg dua cov hlau cam. Tus nqi qis ntawm ductile castings ua rau cov khoom siv no nrov dua, kev ua haujlwm zoo dua qub, thiab cov nqi ua haujlwm ntawm cov ductile castings kuj txo.

Ductile casting kuj muaj ntau dua tensile, plasticity thiab toughness dua li cov grey cam khwb cia hlau zoo tib yam, ductile casting ntxiv rau qhov zoo ib yam li grey cam khwb cia hlau zoo poob siab absorbing, hnav tsis kam, txiav av thiab casting av kos duab. Tensile lub zog mus txog 1200 ~ 1450MPa elongation mus txog 17% cuam tshuam toughness txog 60J / cmz, yog li tau siv los tsim cov quab yuam, tensile, toughness thiab hnav tsis kam thiab lwm yam siab ntawm qhov chaw, xws li tsheb, tsheb laij teb, sab hauv combustion cav, crankshaft, camshaft, thiab dav siv tshuab ntawm nruab nrab siab li qub.

Nodular casting yog cov kua hlau los ntawm kev kho tus neeg sawv cev nodulating es tsis yog tom qab kev kho cua sov. Qee zaum me me ntawm cam khwb cia hlau yog flocculent. Txawm li cas los xij, daim ntawv matrix ntawm nodular casting tuaj yeem hloov pauv tom qab kev kho cua sov, thiab daim ntawv matrix ntawm nodular casting yog: ferrite, pearlite, ferrite ntxiv pearlite, bainite, austenite ntxiv bainite.

Ductile casting nrog kev txhim kho ntawm kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho tib neeg kev ua neej nyob. Ib qho cim tseem ceeb ntawm kev ua tiav lub zog ntawm lub tshuab cuab yeej kev lag luam. Qhov zoo ntawm nodular number case castings feem ntau suav nrog cov tsos zoo, sab hauv zoo thiab siv zoo. Cov tsos zoo ntawm cov cuab yeej cuab tam nodular casting yog hais txog qhov dav dav, qhov tsis xws luag, qhov sib txawv me me, qhov sib txawv ntawm qhov sib txawv thiab qhov hnyav sib txawv ntawm lub tshuab cuab yeej casting. Qhov zoo ntawm cov cuab yeej siv tshuab castings feem ntau yog hais txog cov tshuaj muaj pes tsawg leeg, cov khoom siv lub cev, cov khoom siv kho tshuab, metallographic qauv ntawm lub tshuab cuab yeej nodular castings thiab qhov, tawg, kev sib koom ua ke, kev sib cais thiab lwm yam kev mob uas muaj nyob rau hauv tshuab cuab yeej castings. Kev siv cov cuab yeej zoo ntawm cov cuab yeej nodular number case castings yog hais txog kev ua haujlwm ruaj khov ntawm lub tshuab cuab yeej castings nyob rau hauv cov xwm txheej sib txawv, suav nrog hnav tsis kam, corrosion kuj, txias kub tsis kam, qaug zog, poob siab thiab lwm yam khoom zoo li machinability.
