Qhov tshwj xeeb ntawm I-beam yog qhia nyob rau hauv centimeters ntawm duav dav dav, xws li lub duav dav ntawm No.10 I-beam, uas yog 10cm. Cov hom I-beams muaj xws li kub-dov zoo tib yam I-beams, lub teeb yuag kuv-beams, thiab dav parallel ceg I-beams (H{10}}beams). Lub duav dav ntawm kub- dov zoo tib yam I- kab teeb nyob rau hauv Suav teb yog 100-630mm, thiab inclination ntawm sab hauv phab ntsa ntawm ob txhais ceg yog 1: 6. Lub kaw lus hla rau dov I- kab teeb suav nrog cov kab hluav taws xob ncaj qha rolling pass system, oblique dov pass system, thiab sib xyaw ua ke. Tsis tas li ntawd, txoj kev dov tshwj xeeb kuj tuaj yeem siv rau I-beams.
Hybrid qhov system. Raws li cov yam ntxwv ntawm dov mills thiab cov khoom lag luam, txhawm rau txhawm rau siv qhov zoo ntawm lawv cov kab ke thiab kov yeej lawv qhov tsis txaus, hybrid pass systems feem ntau siv, uas yog, kev sib txuas ntawm ob lossis ntau lub tshuab. Piv txwv li, lub qhov tiav lawm thiab lub hauv ntej lub qhov ntawm cov khoom tiav siv ib tug ncaj ceg kab pheeb ces kaum dov pass system, thaum lwm yam pass hom siv ib tug nkhaus ceg kab pheeb ces kaum dov system; Xwb, ib qho kev sib tw ncaj nraim tuaj yeem siv rau qhov ntxhib dov, thiab ncaj ceg oblique tho qhov tuaj yeem siv rau qhov kawg 3-4 qhov kawg.
Txoj kev dov tshwj xeeb. Thaum nws nyuaj rau dov qhov yuav tsum tau I-beam siv txoj kev dov li niaj zaus vim qee qhov laj thawj, txoj kev dov tshwj xeeb tuaj yeem siv los siv tag nrho cov tswv yim ntawm kev tsis sib xws ntawm kev deformation thiab dhau kev tsim. Piv txwv li, thaum tus ntoo khaub lig-section ntawm steel billet yog nqaim thiab dav dua kuv-beams yuav tsum tau dov, txoj kev yoj dov yuav siv tau; Piv txwv li, thaum lub billet dav dua thiab me dua I- beams yuav tsum tau dov, tsis zoo kis dov yuav siv tau.
Direct rolling pass system. Txoj kab ncaj nraim rolling pass yog hais txog lub kaw lus hla uas ob txhais ceg qhib ntawm I-beam pass nyob rau tib sab ntawm lub yob axis, thiab lub duav yog sib npaug rau lub yob axis.
Hla rolling pass system. Qhov kev hla no yog hais txog ob txhais ceg qhib ntawm I-beam pass uas tsis nyob ntawm tib lub duav ntawm tib lub sijhawm, thiab lub duav muaj lub kaum sab xis nrog txoj kab rov tav.
