Saray valve castings et mainomay ya nawalaan na depekto

1. Say stomata

Saya so melag a lubok ya aporma na gas ya ag-ontaynan ed loob na metal so proseso na panagpaletneg na metal. Say akindalem a dingding to et makinis tan walay gas to, ya atagey so reflectivity to ed ultrasonic wave, balet lapud singa spherical odino ellipsoid, walay depekto to, ya mangaapekta ed reflection amplitude to. Say abut na dagem ed ingot et napapatatdang ed sakey a depekto kayari na panag-forge odino panag-roll, ya makagunggona ya naromog panamegley na ultrasonic detection.

2. I-clip so slag

Say slag ed proseso na panagtunaw odino say refractory ed laman na hurnoan et onkupas ed likidon metal, tan onloob ed casting odino steel ingot no manbububo, ya manporma na depekto na slag clamp. Say slag et kaslakan ya ag manbibilay ya bukor, mabetbet ya makapal odino nitaytayak ed nanduruman kaaralem, mipara itan ed saray depekto ed volume balet mabetbet ya walay linearity to.

3. Say pangipelag na saray bitak

Say bitak ed panag-cast et manunan sengegan na shrinkage stress na metal ya onlelereg so solidification ya onlampas ed sankatageyan ya biskeg na materyal, saya et misiglaotan ed kurti na desinyo na casting tan proseso na panag-cast, tan misiglaotan met ed cracking sensitivity na pigaran impurities ed metal ya materyales (singa say atagey ya sulfur content, cold brittleness, atagey ya phophorus content, tan arum nira). Diad spindle, wala met iray bitak ed shaft crystal, tan diad ontumbok ya billet forging, mansiansia itan ed forging bilang internal crack na forging.

4. Ibalikas so baog

Saya so steelmaking manlapud kutsara ya anggad ingot casting ingot, lapud inkaabala na panagbubo, pause, pangibubo ed likidon metal ya tapew na dagem ya maples ya onlemew ya manporma na oxide film, say balon panagbubo ed likidon metal et onloob ed laman na ingot tan manporma na hierarchical (area) ya depekto, saya ed ontumbok ya ingot billet forging et aliwan forging.

5. Anisotropy

No say casting o ingot et nalemewan tan napalemewan, say kapeles na palemewen manlapud tapew ya anggad sentro et mandumaan, kanian napormay nanduruman crystallization tissue, ya mangipapanengneng na anisotropy na saray mekanikal a kablian, tan mangitonton met ed anisotropy na saray kablian na tanol, salanti, walay nanduruman kapeles na tanol tan say pakaandi na tanol manlapud sentro ya anggad sentro. Say kiwawala na sayan anisotropy et nayarin walay makapuy ya epekto to ed kabaleg tan posisyon na saray depekto ya nausisa legan na ultrasonic detection.

Nilikud ni, say Tianjin Tanggu Water Seal Valve Co., Ltd. et sakey a maaligwas a teknolohiya ya onsusuportad saray negosyo, saray produkto to etelastic seat wafer butterfly valve, lug butterfly valve, double flange concentric butterfly valve, double flangeeksentrikon balbula na kulibangbang, balance valve, wafer dual plate check valve,Y-Strainertan arum nira. Diad Tianjin Tanggu Water Seal Valve Co., Ltd., proud kami ed pangiter mi na saray sankaabigan ya produkto ya makaabot ed sankatageyan ya estandarte na industriya. Lapud dakel so klase na balbula tan kagawaan mi, napanmatalkan yo kamin mangiter na perpekton solusyon parad sistema na danum yo. Kontakin kami natan pian naamtaan so nipaakar ed saray produkto mi tan no panon mi kan natulongan.
