1. Kev soj ntsuam zoo: Cov khoom tsim nyog yuav tsum muaj qhov du thiab tiaj tus, tsis muaj qhov tsis xws luag xws li tawg, folds, nti, pits, thiab xeb. Cov yeeb nkab kawg yuav tsum muaj kev txiav huv si yam tsis muaj burrs lossis bevels. Txias- cov khoom dov yuav tsum muaj qhov ci ntsa iab yam tsis muaj qhov pom tseeb roughness.
2. Dimensional Accuracy Inspection: Siv cov cuab yeej xws li micrometers, vernier calipers, thiab ultrasonic thickness gauges, ntsuas qhov tsis xws li sab nraud, phab ntsa thickness, thiab ntev. Phab ntsa thickness sib txawv ntawm tib tus ntoo khaub lig-section yuav tsum tau tswj nyob rau hauv lub teb chaws tus qauv tso cai ntau yam. Ib txhij txheeb xyuas tias qhov khoov thiab ovality ntawm cov yeeb nkab steel ua tau raws li qhov yuav tsum tau ua ntawm GB / T 17395.
3. Kev Tshawb Fawb Cov Khoom Siv: Ua tshuaj lom neeg muaj pes tsawg leeg kev tshuaj xyuas siv cov khoom siv xws li ncaj qha - nyeem ntawv spectrometer kom paub meej tias qhov sib npaug ntawm cov ntsiab lus xws li carbon, manganese, thiab silicon ua tau raws li cov qauv qib sib xws. Tib lub sijhawm ua cov tensile, cuam tshuam, thiab hardness kuaj kom paub meej tias cov khoom siv xws li lub zog tawm los thiab lub zog tensile ua tau raws li cov qauv.
4. Internal Defect Inspection: Siv cov kev kuaj tsis zoo xws li ultrasonic, eddy tam sim no, thiab kev soj ntsuam cov khoom sib nqus, cov kab nrib pleb hauv, inclusions, thiab lwm yam kev phom sij raug tshuaj xyuas raws li cov qauv xws li GB/T 5779. Rau siab - qhov yuav tsum tau muaj scenarios, kev soj ntsuam radiographic ntxiv tuaj yeem raug kuaj xyuas.
5. Kev Tshawb Fawb Txog Kev Ua Haujlwm: Flattening, flaring, thiab hydraulic xeem tau ua raws li qhov xav tau. Piv txwv li, nyob rau hauv kev ntsuam xyuas hydraulic, lub siab yog teem thiab stabilized siv cov mis p=2Sδ/D. Tsis muaj to lossis deformation qhia tias 合格 (tsim nyog).
