I. Kho qhov tsis xws luag thiab cov txheej txheem
1. Kos, Abrasions, Me Folds
Rau qhov khawb khawb los yog qhov chaw kho tshuab puas tsuaj, siv lub kaum sab xis grinder lossis siv sander rau kev sib tsoo hauv zos kom tshem tawm cov npoo ntse thiab tsim kom muaj kev hloov pauv. Qhov sib tsoo qhov tob yuav tsum tau tswj xyuas thaum kho thiab yuav tsum tsis txhob tshaj qhov tso cai tsis zoo sib txawv ntawm phab ntsa thickness (feem ntau tsis pub tshaj 10%) kom tsis txhob muaj kev cuam tshuam rau lub siab.
2. Sab nrauv folds, hairline cracking, thiab ntiav cov nplais
Yog tias qhov tsis xws luag tsis nkag mus rau hauv lub substrate, cov txheej txheem txawv txav tuaj yeem raug tshem tawm los ntawm kev tig los yog polishing. Qhov no yog tsim rau structural raj nrog tsawg precision yuav tsum. Tom qab kho, eddy tam sim no sim los yog sib nqus particle xeem yuav tsum tau ua kom paub meej tias qhov tsis muaj cov seem seem.
3. Localized Pitfalls thiab Roughness
Cov dents uas tsis nkag mus rau hauv lub raj phab ntsa thiab tsis cuam tshuam lub zog tuaj yeem ua rau hauv av mus rau hauv ib qho kev hloov pauv. Yog tias siv rau kev kho kom zoo nkauj lossis tsis yog - daim ntawv thov siab, qhov tsis xws luag tuaj yeem muab zais los ntawm sandblasting thiab txheej.
4. Kev puas tsuaj ntawm cov xov xaus (cov hniav lwj) me ntsis kev puas tsuaj rau thawj ntu ntawm cov xov tuaj yeem kho tau los ntawm retapping lossis dov. Rau cov ntawv thov uas xav tau kev sib txuas siab zog, nws raug nquahu kom siv cov xov hlau ntxig rau kev kho qhov cuab yeej.
II. Irreversible Severe Defects
1. Internal Folds, Delamination, Inclusions: Cov no yog cov txheej txheem sab hauv uas tsis tuaj yeem tshem tawm los ntawm kev kho deg; tag nrho cov yeeb nkab yuav tsum tau muab pov tseg.
2. Los ntawm -Cracks, Porosity: Cov kev puas tsuaj rau kev ncaj ncees; txawm tias kho los ntawm vuam, kev nyuaj siab concentration yuav qhia. Kev kho thiab siv yog txwv nruj.
3. Cov phab ntsa tuab tuab tsis sib xws, Bulging: Ua los ntawm kev tswj tsis tau dov, cov no tsis tuaj yeem kho thiab yuav tsum tau muab pov tseg tam sim.
4. Deep Scratches (>30μm) los yog Simulated Weld Defects: Cov no yooj yim ua rau qaug zog hauv siab -cov tshuab siab, ua rau muaj kev pheej hmoo; Kev hloov nrog cov yeeb nkab tshiab yog pom zoo.
III. Kev Ntsuas Zoo Tom Qab Kho
Txhua qhov chaw kho yuav tsum tau kuaj xyuas nruj:
1. Tsis yog-Kev kuaj kev puas tsuaj: Ultrasonic kuaj (UT) lossis eddy tam sim no kuaj (ET) yuav raug siv rau rov- tshuaj xyuas kom tsis muaj qhov tawg tshiab.
2. Hydrostatic Test: Kev ntsuas siab yuav ua rau 1.5 npaug ntawm kev ua haujlwm siab tsawg kawg 10 vib nas this. Tsis muaj qhov xau yog suav tias yog txais.
3. Dimensional Verification: Lub sab nraud txoj kab uas hla thiab phab ntsa tuab ntawm qhov kho qhov chaw yuav raug ntsuas los xyuas kom meej tias lawv ua tau raws li qhov tsim nyog tus nqi tsawg kawg nkaus.
⚠️ Raws li GB / T 8163-2023 tus qauv, seamless steel kav siv rau kev xa cov nplaim hluav taws xob lossis cov tshuaj lom neeg tsis raug tso cai rau kev kho txhua yam kev puas tsuaj. Ib qho yeeb nkab uas pom tias muaj qhov tsis xws luag yuav tsum tsis lees txais tam sim ntawd.
