Lub luag haujlwm ntawm leveling yog dab tsi?

Cov txheej txheem theem siv alternately staggered thiab overlapping straightening rollers siv rov qab elastic-yas deformation rau cov hlau sawb hla lawv. Nyob rau hauv tej yam kev mob ntawm qhov tseem ceeb elastic-yas dabtsi yog khoov, tsis hais tus thawj degree ntawm curvature, tom qab rov khoov thiab springback deformation los ntawm leveling rollers, qhov seem sib txawv ntawm curvature ntawm cov yeeb nkab billet yuav txo qis, txawm tias yuav zoo ib yam. Raws li cov degree ntawm rov khoov txo qis, qhov seem curvature tom qab springback inevitably mus zero, maj mam straightening cov yeeb nkab billet thiab thaum kawg ua tiav ib tug macroscopically ca steel strip uas tau raws li qhov yuav tsum tau ntawm cov txheej txheem ntau lawm.
