1. Chemical Composition Verification: Kev txheeb xyuas ntau yam ntawm cov ntsiab lus tseem ceeb xws li C, Mn, thiab Cr yog ua los ntawm cov khoom siv xws li ncaj qha - nyeem ntawv spectrometers kom paub meej tias cov ntsiab lus feem ntau ua tau raws li lub teb chaws cov qauv rau cov qib sib xws, tsis muaj cov khoom siv ntau dhau lossis ploj lawm.
2. Mechanical Property Verification: Tensile, impact, and hardness tests are conducted to confirm that indicators such as tensile strength, yield zog, thiab elongation ua tau raws li cov qauv. Piv txwv li, lub zog tensile ntawm 20G steel kav yuav tsum nyob rau hauv thaj tsam ntawm 410 ~ 550MPa.
3. Kev Ntsuas Metallographic thiab Kev Ua Raws Cai: Kev ntsuas siab thiab qis metallographic yog siv los kuaj xyuas qhov tsis xws luag xws li cov pob dawb thiab delamination. Nyob rau tib lub sijhawm, cov khoom siv qib raug txheeb xyuas raws li cov qauv hauv lub tebchaws rau cov ntawv thov scenario (xws li GB 5310 siab- tus qauv siab boiler raj) kom paub meej tias tsis muaj cov khoom siv tsis raug.
4. Kev Tshawb Fawb Txog Kev Tshawb Fawb: Cov ntaub ntawv pov thawj zoo tau lees paub kom paub meej tias lub tshuab hluav taws xob batch naj npawb thiab cov ntaub ntawv xeem tau sib haum rau cov khoom tiag tiag, txiav txim siab tawm cov teeb meem ntawm cov khoom siv dag zog thiab kev siv cov ntaub ntawv tsis zoo.
