1. Kev soj ntsuam qhov pom thiab qhov ntev
Kev tshuaj xyuas qhov tshwm sim: Saib xyuas seb qhov saum npoo yog du thiab tsis muaj qhov tsis xws luag xws li tawg, tawg, nti, khawb, npuas, lossis oxide nplai. High-cov kav hlau zoo yuav tsum muaj qhov sib xws thiab du nto yam tsis muaj qhov tsis zoo.
Dimensional Accuracy: Siv vernier calipers, micrometers, los yog ultrasonic thickness gauges los ntsuas lub sab nraud txoj kab uas hla, phab ntsa thickness, ntev, thiab ovality kom ua raws li cov qauv xws li GB/T 17395-2008. Phab ntsa thickness sib txawv yog feem ntau tswj tsis pub dhau ± 10%.
2. Tsis yog -Kev Ntsuam Xyuas Kev Puas Tsuaj (NDT)
Siv los txheeb xyuas cov teeb meem sab hauv thiab saum npoo, nws yog ib qho tseem ceeb ntawm kev ua kom muaj kev nyab xeeb:
Kev Ntsuas Ultrasonic (UT): Tshawb xyuas cov kab nrib pleb sab hauv, suav nrog, delamination, thiab lwm yam tsis xws luag. Tus qauv yog GB / T 5777-2019. Nws yog rhiab heev rau longitudinal thiab transverse defects.
Eddy Current Testing (ET): Haum rau qhov chaw tsis xws luag (xws li pinholes thiab microcracks). Nws muaj cov lus teb ceev ceev thiab tsim nyog rau kev soj ntsuam online.
Magnetic particle soj ntsuam (MT): Rau cov ntaub ntawv ferromagnetic, nws tuaj yeem txheeb xyuas ze ntawm - deg defects thiab yooj yim rau kev khiav lag luam.
Kev tshuaj ntsuam hluav taws xob hluav taws xob (RT): Siv los ntsuas qhov tsis xws luag hauv cov kav dej tuab -cov kav dej, tab sis nws kim dua thiab feem ntau yog siv rau cov khoom tseem ceeb.
Kev ntsuam xyuas hluav taws xob ultrasonic: Tsis tas yuav tsum muaj tus neeg sawv cev sib txuas, thiab nws tuaj yeem ua tau tiag tiag - lub sijhawm sim ntawm siab - kub, siab - cov kab ntau lawm, ua raws li tus qauv YB/T 6297-2024 tshiab.
✅ Tus qauv tshiab kawg GB/T 44152-2024 tau teev tseg tias txij Lub Ib Hlis 1, 2025, seamless steel kav nrog ib txoj kab uas hla sab nraud Ntau dua lossis sib npaug li 6 hli yuav tsum tau kuaj ultrasonic hauv 300 hli ntawm cov yeeb nkab kawg. Delamination tsis xws luag nrog thaj tsam> 100mm² yog suav tias tsis tsim nyog.
3. Tshuaj lom neeg muaj pes tsawg leeg tsom xam: C, Mn, Si, P, S, thiab alloying ntsiab (xws li Cr, Mo, Ni) yog soj ntsuam siv ncaj qha - nyeem spectrometers, infrared carbon- sulfur analyzers, thiab lwm yam khoom los xyuas kom meej tias cov khoom ua raws li cov qauv xws li GB/T 3077 thiab ASTM A Qhov muaj pes tsawg leeg ntawm cov khoom tiav yuav tsum nyob rau hauv tus qauv ntau yam; Kev sib txawv ntau dhau yuav cuam tshuam rau lub zog thiab corrosion kuj.
4. Kev ntsuam xyuas cov cuab yeej cuab tam
Tensile Test: Txiav txim siab yield zog (YS), tensile lub zog (TS), thiab elongation (A) kom paub tseeb tias cov khoom thauj khoom -cov kabmob muaj peev xwm.
Impact Test: Ntsuas qis- qhov kub thiab txias, feem ntau siv CVN txoj kev, kom ntseeg tau tias cov yeeb nkab steel tsis tawg brittlely hauv qhov chaw txias.
Hardness Test: Siv Brinell (HB) lossis Rockwell (HRC) hardness tester los txiav txim siab cov khoom sib xws thiab kev ua haujlwm.
Hydraulic Pressure Test: Ua qhov ntsuas siab ntawm 1.5 npaug ntawm kev ua haujlwm siab tsawg kawg 10 vib nas this; tsis muaj qhov xau tau txais. Qhov no yog ib qho yuav tsum tau kuaj xyuas ua ntej ua zaub mov xa tuaj.
5. Txheej Txheem Kev Ua Haujlwm thiab Kev Ntsuas Metallographic
Flattening Test: Simulates lub peev xwm deformation thaum lub sij hawm cov yeeb nkab txuas los xyuas qhov tawg.
Flanging thiab dabtsi yog khoov Test: Txheeb xyuas qhov ua tau zoo.
Kev Tshuaj Xyuas Metallographic: Saib xyuas qhov microstructure, xws li cov nplej loj, tsis yog -metallic inclusions, thiab decarburized txheej, siv lub microscope los xyuas kom meej cov microstructure zoo ib yam.
