Daim Ntawv Pov Thawj Kev Cai rau Txheej Thickness Gauge
Feem ntau ntawm cov hlau tsis muaj steel siv rau cov nplooj ntawv zoo nkauj yog cov khoom siv austenitic 304, feem ntau hais lus, nws tsis yog hlau nplaum los yog tsis muaj zog hlau nplaum, tab sis nws kuj tseem tuaj yeem tshwm sim sib nqus vim cov tshuaj muaj pes tsawg leeg hloov pauv lossis cov txheej txheem sib txawv tshwm sim los ntawm smelting, tab sis qhov no tsis tuaj yeem ua tau. suav tias yog Counterfeit lossis tsis tsim nyog, yog vim li cas? Raws li tau hais los saum toj no, austenite tsis yog hlau nplaum lossis tsis muaj zog sib nqus, thaum martensite lossis ferrite yog sib nqus. Vim muaj kev sib cais los yog kev kho cua sov tsis tsim nyog thaum smelting, me me ntawm martensite lossis ferrite hauv austenitic 304 stainless hlau yuav raug tsim. lub cev nqaij daim tawv. Ua li no, 304 stainless hlau yuav muaj zog hlau nplaum. Tsis tas li ntawd, tom qab ua haujlwm txias ntawm 304 stainless hlau, microstructure tseem yuav hloov mus rau martensite. Qhov ntau dua qhov kev ua haujlwm txias deformation, qhov hloov pauv martensite ntau dua, thiab ntau dua cov khoom sib nqus ntawm cov hlau. Zoo li ib pawg ntawm cov hlau strips, Φ76 hlab yog tsim, tsis muaj qhov pom tseeb sib nqus induction, thiab Φ9.5 hlab yog tsim. Qhov sib nqus induction yog qhov pom tseeb dua vim qhov loj dua txias bending deformation. Lub deformation ntawm cov kav dej square thiab cov duab plaub yog loj dua li cov kav dej puag ncig, tshwj xeeb tshaj yog nyob rau ntawm cov ces kaum, thiab qhov deformation yog khaus thiab cov hlau nplaum yog qhov pom tseeb dua. Yuav kom tshem tawm tag nrho cov hlau nplaum ntawm 304 steel los ntawm cov laj thawj saum toj no, cov qauv austenite ruaj khov tuaj yeem rov qab los ntawm kev kho kub kub, kom tshem tawm cov hlau nplaum. Tshwj xeeb, cov hlau nplaum ntawm 304 stainless hlau vim yog cov laj thawj saum toj no tsis nyob rau tib theem li ntawm lwm cov hlau stainless, xws li 430 thiab carbon hlau. Uas yog hais, cov hlau nplaum ntawm 304 steel ib txwm qhia tsis muaj zog hlau nplaum. Qhov no qhia peb tias yog cov hlau tsis muaj hlau nplaum tsis muaj zog lossis tsis muaj hlau nplaum, nws yuav tsum raug txheeb xyuas tias yog 304 lossis 316 cov khoom; Yog tias nws zoo ib yam li carbon steel, nws qhia tau tias muaj zog hlau nplaum, vim nws tsis yog 304 khoom
