Dab tsi yog cov theem hauv kev tsim cov ntawv hlau cov hlau?

Ntawm cov hom steel ntawv piles,U daim ntawvFeem ntau dav siv, ua raws li cov ntawv hlau txheej ntawm U-puab txheej txheem ntawm U-puab cov ntawv hlau piles yog 529 × 10-5m3 / Txiv neej, uas yog qhov tsim nyog rau kev rov siv dua , thiab feem ntau nws siv nyob rau hauv cov qauv ib ntus. Nyob rau hauv neutral axis txoj hauj lwm yog nyob rau hauv lub puab loking hauv cov phab ntsa sib zog. Nrog ob qhov chaw xauv qhov kawg ntawm txoj kev sib dhos ntawm cov txheej txheem weldly ntawm ob hom steel ntawv pawg ntawm cov qauv hlau pawg Cov. Raws li rau cov plhaub cov khoom ntawm cov hlau sib xyaw ua ke, muaj cov ntu loj tuaj yeem tau los ntawm kev sib sau ua ke ntawm cov hlau hlau pawg. Raws li cov qauv tsim qauv thiab kev tsim kho, qhov ntev ntawm cov khoom siv tuaj yeem hloov tau.

U puab steel ntawv pawg pawgThiab kab steel sheet yog tsim los ntawm cov chaw tsim khoom, txawm hais tias cov khoom siv siv los ntawm cov kauj ruam ntau lawm ntawm cov ntawv sib tw yog cov kwv yees li nram no:
Steel ntawv pawg yog ua los ntawm cov qauv hlau loj loj lossis tom qab calendering rhuab Ntu duab. Lub tiav lawm calendered steel ntawv pawg yog txiav tawm ntawm qhov kub thiab txias raws li cov khoom siv ntev. Tom qab txias, cov ntawv pawg tau dhau los ntawm ib lub tshuab ruaj kom kho cov khoov thiab warps tsim thaum lub sijhawm.
