Hais tias qhov zoo ntawmductile hlau yeeb fittingsyog tshwj xeeb nyob rau hauv dab tsi yam, ces peb muaj peev xwm ua ntej ntawm tag nrho cov yuav tsum tau lub zog ntawm cov khoom, thiab muaj cov ntaub ntawv tseeb thiab cov ntaub ntawv ntseeg tau ua pov thawj. Raws li kev sim, lub zog tensile ntawm nodular cam khwb cia hlau yog 60k, thaum uas zoo tib yam grey cam khwb cia hlau yog 31k. Qhov ob yog piv rau lwm qhov, uas yog, lub zog tawm los, qhov qis tshaj tawm lub zog ntawm cov hlau hlau yog 40k, thaum lub zog tawm los ntawm cov hlau grey zoo tib yam tsuas yog 36k.
Cov yeeb nkab hlau fittings muaj xws li cam khwb cia hlau ncaj yeeb nkab thiab cov yeeb nkab fittings, uas feem ntau yog tsim los ntawm cov cam khwb cia hlau. Vim hais tias hom yeeb nkab siv zog no tsis loj, yog li tsuas yog siv tau rau kev siv dej, dej, roj thiab lwm cov kab sib txuas. Yog tias nws raug cais raws li txoj kev sib txawv, cov kav hlau cam kuj tseem tuaj yeem muab faib ua cov kav hlau txuas txuas ntxiv thiab cov kav dej centrifugal cam khwb cia hlau, thiab kev ua haujlwm ntawm cov khoom kuj tseem txawv.
Txoj kev smelting ntawm ductile hlau yeeb nkab zoo ib yam li lwm yam kev lag luam casting. Qhov txawv yog tias cov yeeb nkab hlau yuav tsum tau ntxiv qee tus neeg sawv cev teeing ua ntej pib casting, xws li: Magnesium los yog lub ntiaj teb tsis tshua muaj magnesium ua ke nrog kub spheroidizing tus neeg sawv cev ntxiv rau cov hlau kub ua ntej pouring, kom cov graphite spheroidization, kev nyuaj siab concentration txo, yog li ntawd cov yeeb nkab muaj qhov zoo ntawm lub zog siab, siab elongation, sealing resistance, corrosion resistance, zoo.
Thiab ductile hlau yeeb nkab fittings yog ua los ntawm cov txheej txheem hlau ductile, ntxiv rau cov kev sib kis ntawm cov dej, dej thiab lwm yam khoom siv, kuj tuaj yeem siv los ua cov kav dej los tiv thaiv corrosion. Qhov no feem ntau yog vim cov yeeb nkab hlau yeeb nkab muaj kev ua tau zoo heev, tib lub sijhawm, kev pabcuam lub neej, siab thiab lwm yam kuj yog qhov zoo tagnrho, thiab vim muaj kev tiv thaiv zoo los ntawm feem coob ntawm cov neeg siv.
