Cam khwb cia hlau yeeb nkab
Lus piav qhia luv luv:
Cam khwb cia hlau yeeb nkab yog hais txog ib tug yeeb nkab cam khwb cia hlau cam khwb cia hlau.cam khwb cia hlau yeeb nkab yog siv rau cov khoom siv dej, cov kav dej thiab cov kav dej xa hluav taws xob, suav nrog cov kav hlau ncaj ncaj thiab cov yeeb nkab fittings.Kev siv zog ua haujlwm tsawg.Raws li kev sib txawv casting, nws tau muab faib ua ntu nruam cam khwb cia hlau yeeb nkab thiab centrifugal cam khwb cia hlau yeeb nkab, ntawm cov centrifugal cam khwb cia hlau yeeb nkab yog muab faib ua xuab zeb pwm thiab hlau pwm.Raws li cov ntaub ntawv sib txawv, nws muab faib ua grey cam khwb cia hlau yeeb nkab thiab ductile hlau yeeb nkab.Raws li cov ntaub ntawv sib txawv, nws tau muab faib ua qhov hloov pauv tau yooj yim, flange interface, tus kheej thauj tog rau nkoj interface, nruj interface, thiab lwm yam.

Lub ntsiab ntawm cov yeeb nkab hlau cam khwb cia hlau yog cov yeeb nkab hlau, uas yog hu ua qhov no vim nws muaj qhov xwm ntawm hlau thiab kev ua haujlwm ntawm cov hlau.Cov graphite hauv cov yeeb nkab hlau muaj nyob rau hauv daim ntawv kheej kheej, thiab qhov loj ntawm graphite feem ntau yog 6-7.Qhov zoo yuav tsum tau spheroidization theem ntawm cam khwb cia hlau yeeb nkab yuav tsum tau tswj mus rau qib 1-3, thiab spheroidization tus nqi yog ≥80%, yog li cov neeg kho tshuab cov khoom ntawm nws tus kheej yog zoo txhim kho, nrog rau cov xwm ntawm hlau thiab kev ua tau zoo ntawm hlau. .Tom qab annealing, cov qauv metallographic ntawm cov yeeb nkab hlau yog ferrite ntxiv rau ib qho me me ntawm pearlite, thiab cov cuab yeej siv tau zoo, yog li nws tseem hu ua cam khwb cia hlau yeeb nkab.
