Dab tsi tsis xws luag yog nquag rau valve castings?

1. Lub stomata

Nov yog cov kab noj hniav me me tsim los ntawm cov roj uas txoj kev hlau ua tsis dim ntawm cov hlau. Nws sab hauv phab ntsa yog tus thiab muaj cov roj av, uas muaj qhov ua kom muaj kev cuam tshuam ultrasonic, nws yog ib qho xwm txheej ultrasonic, uas cuam tshuam rau nws cov kev cuam tshuam txog kev cuam tshuam. Lub qhov cua cua hauv lub ingot yog flattened rau hauv ib qho chaw puas tom qab forging lossis dov, uas tau txais txiaj ntsig tau los ntawm kev kuaj ultrasonic.

2. Rettract thiab xoob qhov

Thaum lub casting lossis ingot yog txias thiab solunified, lub ntim yuav tsum ntsws, thiab hollow qhov puas tuaj yeem tsis tuaj yeem muab cov hlau ua kua. Loj thiab muaj lub suab nrov yog hu ua shrinkage qhov, thiab cov verttered voids tau hu ua xoob. Vim txoj cai ntawm kev nthuav dav ntawm thermal thiab txias dua, qhov sib txawv ntawm cov txheej txheem sib txawv, tab sis nws dhau los ua qhov tsis sib xws thaum nws ncua rau lub cev lossis inglot lub cev. Yog hais tias lub ingot tsis txiav cov qhov shrinkage huv si thiab coj nws mus rau hauv qhov kev zam txim seem, nws yuav dhau los ua ib qho seem shrinkage (seem shrinkage qhov, seem shrinkage yeeb nkab).

3. Clip Slag

Lub shell hauv cov txheej txheem smelting lossis cov refractory ntawm cov cua sov lub cev paj nruag tawm mus rau hauv cov hlau ua kua, thiab yog kos rau hauv lub ntsej muag ua kua lossis sib xyaw ua ke, tsim lub ntsej muag tawv ncauj. Slag feem ntau tsis muaj nyob ib leeg, feem ntau nyob rau hauv lub xeev tuab lossis tawg ntawm qhov sib txawv, nws zoo ib yam li ntim tsis xws luag tab sis feem ntau muaj ib qho lineinity.

4. Mixed

Cov tshuaj tiv thaiv cov txheej txheem hauv smelting txheej txheem (xws li oxide, xws li cov khoom siv sib txawv, lossis cov khoom siv sib txawv, ua kom pom kev zoo siab, lossis cov molybdenum, thiab lwm yam.

5. Phau Ntawv Qhia

Txoj kev cais tawm hauv kev ua pov lossis cov kev faib tawm tsuas yog hais txog kev faib tawm feem hauv cov txheej txheem tsis sib xws los yog cov txheej txheem melting ntawm cov hlau. Cov khoom siv tshuab ntawm thaj chaw nrog kev cais tawm txawv ntawm cov tshuab hlau ntawm tag nrho cov hlau uas tau tso cai ua ib qho kev tsis taus.

6. Khov tawg

Cov kab nrib pleb hauv lub nrib yog feem ntau tshwm sim los ntawm shrinkage kev ntxhov siab ntawm qee cov khoom siv hluav taws xob, thiab tseem muaj cov ntsiab lus ntawm cov hlau nplaum (xws li cov ntsiab lus siab Nyob rau hauv spindle, tseem yuav tau tawg nyob rau hauv ncej lead ua lead ua, thiab nyob rau hauv lub npov txuas ntxiv, nws yuav nyob hauv kev forging raws li kev tawg sab hauv.

Dhau li, Tianjin Tanggu Dej Riam Valve Co., Ltd. Advanced Advention Elastic Lub Rooj Ncaws Pob, cov khoom yogRoj Hmab Tog Wafer Npauj Npaim Valve, Lug Npab Npaim Valve, Ob Chav Flange Ob Chav Tshaj Tawm Npauj Npaim Valve, Ob Chav FlangeEccentric Npauj Npaim Valve, sib npaug sib npaug valve,Daim Duab Wafer Dual Kos Valve, Y-lim thiab li ntawd. Ntawm Tianjin Tanggu Dej Hla Valve Co., Ltd., peb muaj txiaj ntsig peb ntawm kev muab cov khoom lag luam ua ntej. Nrog peb cov kev dav dav ntawm cov li qub thiab fittings, koj tuaj yeem ntseeg peb kom muab cov tshuaj zoo tshaj plaws rau koj cov dej. Tiv tauj peb rau peb niaj hnub no kom paub ntau ntxiv txog peb cov khoom lag luam thiab peb tuaj yeem pab koj li cas.
