Cov khoom siv valve castings feem ntau ua rau muaj qhov tsis zoo

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 ultrasonic nrhiav.

2. Txiav cov slag

Cov slag hauv cov txheej txheem smelting lossis cov refractory ntawm lub cev cub tawg rau hauv cov hlau ua kua, thiab koom nrog 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.

3. 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.

4. Tig daim tawv nqaij

Qhov no yog kev ua hlau los ntawm lub ladle mus rau lub ingot casting ingot, vim yog kev cuam tshuam ntawm kev nchuav, ncua, nchuav rau hauv cov hlau ua kua hauv huab cua txias sai sai daim ntawv oxide zaj duab xis, tshiab nchuav rau hauv cov hlau ua kua yuav tawg rau hauv lub cev ingot thiab tsim ib qho hierarchical (cheeb tsam) qhov tsis zoo, nws nyob rau hauv lub tom ntej ingot billet forging tsis yog forging.

5. Kev tsis sib haum xeeb

Thaum lub casting lossis ingot txias thiab khov, qhov ceev txias ntawm qhov chaw mus rau qhov chaw nruab nrab yog txawv, yog li cov ntaub so ntswg crystallization sib txawv yuav tsim, uas qhia txog anisotropy ntawm cov khoom siv kho tshuab, thiab tseem ua rau anisotropy ntawm cov khoom acoustic, uas yog, muaj qhov ceev suab sib txawv thiab suab attenuation ntawm qhov chaw mus rau qhov chaw. Qhov muaj qhov anisotropy no tuaj yeem muaj qhov tsis zoo rau qhov loj me thiab qhov chaw ntawm cov qhov tsis zoo uas tau soj ntsuam thaum lub sijhawm ultrasonic nrhiav.

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 yoglub rooj zaum elastic wafer npauj npaim valve, lug npauj npaim valve, ob chav flange concentric npauj npaim valve, ob chav flangeeccentric npauj npaim valve, qhov sib npaug ntawm lub valve, wafer dual phaj check valve,Y-Strainerthiab lwm yam.
