Peko ango ma copo wok ikum valve castings?

1. The stomata

Eni ubedo vur ma nok ma juyubu ku yamu ma tic mi ketho cuma doko tek uwok ungo kud i cuma. Cel pare ma iye utiye mayom man utiye ku yamu, ma utiye ku kero madit mi dwoko wange i ultrasonic wave, ento pi en etiye spherical nyo ellipsoid, etiye point defect, ma nyayu peko i kum dwoko wange. Kabedo mi yamo i ingot juyike i kabedo ma rac ingey yubu nyo guro, ma ber ni nwangu ku ultrasonic inspection.

2. Retraction man loose hole

Ka casting nyo ingot ubedo ma ngic man edoko tek, dwong pa piny ucikere ni dwoko piny, man peko ma iye copo bedu ngo ku cuma ma pii. Vovities madongo man ma nyai julwongo gi ni shrinkage holes, man voids ma nok man ma nyai julwongo gi ni loose. Ni lubre ku cik mi nyai pa lyethu man nyai pa ngico, vur mi nyai nyai utiye, ento utiye ku kit, dit man kabedo matung tung ku yore mi tic matung tung, man edoko rac ka edaru ikum piny ma jucwalo nyo ingot. Ka ingot ne ungolo ngo vur ma nyai man ekelo ngo i thenge mi forging, ebidoko vur ma nyai (vur ma nyai, paip ma nyai).

3. Clip slag

Slag ma nwangre i tic mi lyethu nyo refractory ma ni i kum furnace wok woko i cuma ma pii, man juwodho i casting nyoke steel ingot ka jupodho, ma weko slag clamp defect. Slag pol kare epe kende, pol kare i rwom ma lac nyo nyai i thenge matung tung, e rom ku volume defects ento pol kare etiye ku linearity moku.

4. Jurubu

Piny ma wok kud i tic mi yiko piny (macalu oxide, sulfide, man mange) - piny ma mako ngo cuma, nyo piny ma jumedo i kum piny moko ma juyubu ngo man udong pi yubu cuma, calu high density, high melting point components-tungsten, molybdenum, man mukende mapol.

5. Wec

Poko piny i casting nyo ingot nyutho apoka pa piny ma wok i poko pa piny ma rom ungo i tic mi lwoko nyo i yub mi lwoko cuma. Kit tic pa kabedo ma jupoko kudu opokiri ku kit tic pa metal matrix, man tung tung ma kadhu rwom ma juyiyu doko rac.

6. Casting cracks

Tur pa piny ma jucwalo eca wok ikum shrinkage stress pa cuma ma ngic ma tek ma kadhu tego pa piny ne, etiye ku winjiri ku kit ma juyubu kudu man kite ma juyubu kudu piny ne, man bende etiye ku winjiri ku tur pa piny moko ma reco (macalu sulfur madwong, cold brittleness, highphorus, etc.). I spindle, ebibedo ku tur i shaft crystal, man i billet forging ma lubo, ebibedo i forging calu crack mi iye pa forging.

Mi mede, Tianjin Tanggu Water Seal Valve Co., Ltd. utiye dilo ma rwom pare malu ma konyo dul ma timo tic, piny ma juyubu utiyerubber seat wafer butterfly valve, lug butterfly valve, double flange concentric butterfly valve, double flangeeccentric butterfly valve, balance valve,wafer dual plate check valve, Y-Strainer man mukende mapol. I Tianjin Tanggu Water Seal Valve Co., Ltd., wabedo kud anyonga ni mio piny maber ma rwate ku cik ma malu pa tic. Ku kit valves man fittings mwa madwong, icopo yio wa ni wabi miyo iri kony maber pi pii peri. Lwong wa tin pi ningeyo lembe madwong ikum piny mwa man kite ma wacopo konyi kudu.
