EN-GJS 400-15 / 500-7 Cov Hlau Uas Ua Los Ntawm Yas | Cov Hlau Uas Muaj Graphite Spheroidal
Kev Taw Qhia Txog Khoom
EN-GJS 400-15 / 500-7 Cov Hlau Uas Muaj Peev Xwm Loj yog cov khoom siv hlau uas ua tau zoo heev uas tsim los raws li cov qauv European, tsim tshwj xeeb rau cov ntawv thov uas xav tau lub zog siab, kev ua tau zoo, thiab kev ua haujlwm tau zoo dua. Cov hlau no yog tsim los nrog cov qauv graphite spheroidal, uas muaj cov yam ntxwv tensile zoo kawg nkaus thiab kev tiv taus kev cuam tshuam, ua rau lawv yog qhov kev xaiv ntau yam rau cov qauv thiab cov ntawv thov kho tshuab.
Cov koob EN-GJS tau txais kev qhuas tshwj xeeb hauv Tebchaws Europe rau kev muab ntau yam kev sib xyaw ua ke ntawm lub zog thiab kev ntev. EN-GJS 400-15 yog tus cwj pwm los ntawm kev ua kom zoo thiab kev tawv, thaum EN-GJS 500-7 muab lub zog siab dua thaum tswj kev ywj pheej txaus. Cov hlau ductile no yog qhov tsim nyog rau cov khoom uas raug kev ntxhov siab rov ua dua, kev co, lossis kev cuam tshuam nruab nrab. Lawv qhov kev siv tshuab ua rau lawv zoo tagnrho rau ob qho tib si roughing thiab precision finishing operations.
- 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.
