Qhov sib txawv ntawm cov khoom siv qis-siab thiab cov siab sib txawv
1. Lub ntsiab cai tseem ceeb:
Tsawg Tshaj Casting:
Los ntawm kev thov cov siab qes (feem ntau {{0}}}}}}}}}}. Cov txheej txheem yog ruaj khov thiab haum rau cov nyom sib lo-walled.
Plawg siab Casting:
Lub pwm thiab melting rauv yog muab faib ua ob qho siab, sab saud thiab qis. Los ntawm kev thov cov kev cai sib txawv (xws li pwm kab kab kab kab kab hniav pressurization thiab rauv qhov sib txawv yog tsim kom tsav cov ntaub hlau nrawm ntawm cov hlau molten. Qhov siab sib txawv yog loj (mus txog {{{0}}}}}. 3 ~ 0.5 MPa
2. Txheej Txheem Txheej Txheem:
Tsawg Tshaj Casting:
Cov txiaj ntsig zoo: du filling thiab txo cov roj oxidation; Haum rau lub teeb sib xyaw xws li txhuas alloys thiab magnesium alloys; Cov pwm muaj lub neej ntev.
Qhov tsis zoo: qhov kev sib tw tsis tshua muaj siab thiab qhov nruab nrab ntom ntawm cov qauv; Kev ua haujlwm ntau ntau.
Daim ntawv thov: automotive log hubs, cav lub tog raj kheej blocks, thiab lwm yam uas nyuaj.
Plawg siab Casting:
Cov txiaj ntsig: saldification nyob rau hauv kev kub siab sib txawv, siab ntom ntawm castings; Tuaj yeem txo cov porosity thiab shrinkage; Haum rau high-zog Cheebtsam.
Qhov tsis zoo: Cov cuab yeej nyuaj thiab tus nqi siab; Qhov nyuaj ntawm cov txheej txheem tswj tau yog qhov siab.
Cov ntawv thov: Aerospace cov txheej txheem, muaj kev ua tau zoo siv tsheb.
3. Tub ntxhais hluas sib txawv:
Txoj kev siab: Qis Casting relies ntawm ib lub siab tau, thaum muaj kev sib txawv ntawm cov siab sib txawv ntawm cov chaw sab saud thiab qis.
Solidification Zoo: Plawg Siab Casting tuaj yeem kho cov qoob loo loj dua thiab txhim kho cov khoom siv txhua tus vim kev kub siab sib txawv.
Cov Khoom Siv Khoom Siv Ua Si: Cov khoom siv sib txawv ntawm cov khoom siv yuav tsum muaj dual lub zog, ua kom tswj tau ntau yam.
Cov ntsiab lus tseem ceeb rau cov khoom xaiv ntawm Ceramic Riser Tube
Tus riser yog qhov tseem ceeb tiv thaiv rau kev thauj cov kua hlau, uas yuav tsum tau tiv thaiv cov kua roj siab, thermal poob siab, kev xeb, thiab siv zog yaig. Kev xaiv cov ntaub ntawv yuav tsum coj mus rau hauv tus account cov hauv qab no:
1. Khoom siv ua tau zoo:
Kev kub siab kuj: nws yuav tsum tau tiv thaiv qhov kub ntawm Molten hlau (txog 700 degree c rau txhuas alloy thiab txog 650 degree c rau magnesium alloy).
Thermal poob siab: Tsis muaj kev tawg ntoj tawg thiab kub cycles (cov kauj vab kub (sib txawv cas
Tshuaj lom neeg ruaj khov: tsis muaj kev cuam tshuam nrog cov kua hlau (xws li magnesium ntau uas tau nquag los ua kom muaj oxides thiab xav tau inert cov ntaub ntawv).
Mechanical zog: Tiv thaiv txoj kev yosion thiab kev cuam tshuam siab los ntawm kev ntws ntawm cov hlau molten.
