Muaj nuj nqi ntawm Leveling

Vim yog qhov sib npaug, staggered, thiab sib tshooj ntawm cov qib yob, cov hlau sawb hla ntawm lawv tau rov ua dua elastic-yas deformation. Nyob rau hauv cov xwm txheej ntawm qhov tseem ceeb elastic-yas dabtsi yog khoov, tsis hais txog ntawm qhov pib ntawm qhov curvature, tom qab kev rov qab khoov deformation thiab elastic rov qab deformation los ntawm leveling rolls, qhov sib txawv ntawm qhov seem curvature ntawm cov yeeb nkab billet yuav txo qis, txawm tias tending los ua uniform. . Raws li cov degree ntawm rov khoov txo qis, qhov seem curvature tom qab elastic rov qab inevitably nyhav ntawm xoom, thiab cov yeeb nkab billet maj mam ua ncaj, thaum kawg tau txais ib tug macroscopically ca steel strip uas ua tau raws li cov txheej txheem ntau lawm.
