1. Lub qhov ncauj
Qhov no yog ib lub qhov me me uas tsim los ntawm cov roj uas cov txheej txheem khov kho tsis tawm hauv cov hlau. Nws sab hauv phab ntsa yog du thiab muaj cov roj, uas muaj kev cuam tshuam siab rau lub zog ultrasonic, tab sis vim nws yog lub voos xwmfab lossis ellipsoid, nws yog qhov tsis zoo, uas cuam tshuam rau nws qhov kev cuam tshuam amplitude. Lub qhov cua hauv lub ingot yog flattened rau hauv ib cheeb tsam tsis zoo tom qab forging lossis dov, uas yog qhov zoo kom pom los ntawm kev tshuaj xyuas ultrasonic.
2. Kev rub rov qab thiab qhov xoob
Thaum lub casting lossis ingot txias thiab khov, qhov ntim yuav tsum ntsws, thiab qhov tsis zoo ntawm lub hollow tsis tuaj yeem ntxiv los ntawm cov hlau kua. Cov vov loj thiab concentrated hu ua qhov shrinkage, thiab cov voids me me thiab tawg hu ua xoob. Vim yog txoj cai ntawm thermal expansion thiab cold contraction, lub shrinkage qhov yuav tsum muaj, tab sis muaj ntau yam duab, qhov loj me thiab qhov chaw nrog ntau txoj kev ua tiav, thiab nws dhau los ua qhov tsis zoo thaum nws nthuav mus rau lub cev casting lossis ingot. Yog tias lub ingot tsis txiav lub shrinkage qhov huv thiab coj nws mus rau hauv cov khoom forging, nws yuav dhau los ua qhov shrinkage seem (qhov shrinkage seem, cov yeeb nkab shrinkage seem).
3. Txiav cov slag
Cov slag hauv cov txheej txheem smelting lossis cov refractory ntawm lub cev cub tawg tawm mus rau hauv cov hlau ua kua, thiab raug rub mus rau hauv cov casting lossis hlau ingot thaum nchuav, tsim cov slag clamp defect. Slag feem ntau tsis muaj nyob ib leeg, feem ntau nyob rau hauv lub xeev ntom lossis tawg ntawm qhov tob sib txawv, nws zoo ib yam li cov ntim defects tab sis feem ntau muaj qee yam linearity.
4. Sib xyaw
Cov khoom lag luam hauv cov txheej txheem smelting (xws li oxide, sulfide, thiab lwm yam) - cov khoom tsis yog hlau, lossis cov khoom ntxiv ntawm qee cov khoom hauv cov khoom hlau tsis yaj tag thiab tseem nyob ua cov khoom siv hlau, xws li cov khoom siv siab, cov khoom siv melting siab - tungsten, molybdenum, thiab lwm yam.
5. Txhais lus luv luv
Qhov kev sib cais hauv kev casting lossis ingot feem ntau yog hais txog kev sib cais ntawm cov khoom tsim los ntawm kev faib tawm tsis sib xws ntawm cov khoom hauv cov txheej txheem smelting lossis cov txheej txheem yaj ntawm cov hlau. Cov khoom siv kho tshuab ntawm thaj chaw nrog kev sib cais yog txawv ntawm cov khoom siv kho tshuab ntawm tag nrho cov hlau matrix, thiab qhov sib txawv dhau qhov kev tso cai tus qauv ntau dhau los ua qhov tsis xws luag.
6. Kev tawg ntawm cov kab nrib pleb
Qhov tawg hauv qhov casting feem ntau yog tshwm sim los ntawm kev ntxhov siab ntawm cov hlau txias txias solidification tshaj qhov kawg zog ntawm cov khoom siv, nws muaj feem cuam tshuam rau cov duab ntawm casting tsim thiab casting txheej txheem, thiab tseem muaj feem cuam tshuam rau qhov tawg rhiab heev ntawm qee qhov tsis huv hauv cov khoom siv hlau (xws li cov ntsiab lus sulfur siab, txias brittleness, cov ntsiab lus phosphorus siab, thiab lwm yam). Hauv lub spindle, kuj tseem yuav muaj cov tawg hauv lub shaft siv lead ua, thiab hauv billet forging tom qab, nws yuav nyob hauv forging ua qhov tawg sab hauv ntawm forging.
Dhau li ntawm qhov ntawd, Tianjin Tanggu Water Seal Valve Co., Ltd. yog lub tshuab ua haujlwm siab heev uas txhawb nqa cov lag luam, cov khoom lag luam yogroj hmab rooj zaum wafer npauj npaim valve, lug npauj npaim valve, ob chav flange concentric npauj npaim valve, ob chav flangeeccentric npauj npaim valve, lub valve sib npaug,wafer ob lub phaj check valve, Y-Strainer thiab lwm yam. Ntawm Tianjin Tanggu Water Seal Valve Co., Ltd., peb txaus siab rau peb tus kheej hauv kev muab cov khoom lag luam zoo tshaj plaws uas ua tau raws li cov qauv kev lag luam siab tshaj plaws. Nrog peb cov ntau yam ntawm cov li qub thiab cov khoom siv, koj tuaj yeem ntseeg peb kom muab cov kev daws teeb meem zoo tshaj plaws rau koj lub kaw lus dej. Tiv tauj peb hnub no kom paub ntau ntxiv txog peb cov khoom thiab peb tuaj yeem pab koj li cas.
