Kev Taw Qhia Txog Khoom
Cov Hlau Uas Muaj Zog Siab yog cov khoom siv zoo tshaj plaws uas tsim tshwj xeeb rau cov khoom siv kho tshuab uas xav tau ob qho tib si kev tawv thiab kev ua haujlwm tau zoo. Kuj tseem hu ua SG Iron lossis Spheroidal Graphite Iron, cov khoom siv no muab kev ywj pheej ntawm cov hlau nrog cov khoom siv kho tshuab uas ze rau hlau. Nrog nws lub zog tshwj xeeb, kev siv tshuab zoo heev, thiab kev co damping peev xwm, cov hlau ductile tau dhau los ua qhov kev xaiv zoo tshaj plaws rau ntau yam kev siv hauv kev lag luam, suav nrog cov tshuab hydraulic, cov khoom siv tshuab, thiab cov khoom xa hluav taws xob.
Tsis zoo li cov hlau grey, cov hlau ductile muaj cov graphite hauv daim ntawv kheej kheej, uas ua rau nws lub zog tensile thiab tiv taus kev cuam tshuam. Qhov zoo ntawm cov qauv no ua rau nws muaj zog nyob rau hauv cov xwm txheej hnyav, ua rau nws haum rau ob qho tib si static thiab dynamic loads. Cov hlau ductile muaj nyob rau hauv ntau txoj kab uas hla thiab tuaj yeem muab rau hauv cov xwm txheej ntxhib lossis precision-machined kom phim cov kev xav tau ntawm kev lag luam sib txawv.
- cov hlau ductile yog tsim tawm raws li cov qauv thoob ntiaj teb. Cov qib hlau uas siv ntau ntawm cov hlau ductile yog qhia tawm ntau txoj hauv kev raws li ntau lub tebchaws thiab cov qauv.
Cov hauv qab no yog cov qib hlau ductile uas siv ntau tshaj plaws (qib) raws li ntau lub tshuab txheem:

Kev piav qhia txog khoom
Cov hlau ductile yog ib yam khoom siv uas txhim kho nws cov khoom siv kho tshuab los ntawm kev ntxiv cov neeg sawv cev spheroidizing xws li magnesium lossis cerium rau hauv cov hlau cam khwb cia kom tsim graphite rau hauv cov qauv spheroid. Hais txog cov tshuaj lom neeg sib xyaw, cov khoom tseem ceeb ntawm cov hlau ductile yog hlau, carbon, silicon, nrog rau manganese, phosphorus, sulfur thiab lwm yam ntsiab lus. Kev ntxiv cov neeg sawv cev spheroidizing xws li magnesium lossis cerium yog qhov tseem ceeb, uas txhawb nqa kev tsim cov qauv spheroidizing hauv graphite.
Cov pas nrig hlau ductile feem ntau siv rau hauv cov chaw xws li cov iav thiab cov qhov chaw hauv kev tsim khoom siv tshuab, crankshafts thiab cov pas nrig txuas hauv kev lag luam tsheb, cov kav dej thiab cov khoom siv hauv kev tsim kho, cov khoom siv hydraulic hauv kev tsim kho tshuab, thiab cov li qub thiab cov twj tso kua mis hauv kev lag luam zog.
