Q345d Kub Rolling Steel Coils

Kub dov txoj cai
1. Txoj kev xav ntawm dov: Rolling yog ib txoj hauv kev uas kev sib txhuam ntawm cov rotating rollers yog siv los rub lub workpiece mus rau hauv chav tsev ntawm cov chais, thiab tib lub sij hawm, lub siab exerted los ntawm rollers ua rau lub workpiece mus rau compression. deformation ntawm ob los yog ntau tshaj rollers. Cov txheej txheem ua khoom siv.
2. Rolling tsis: Thaum lub sij hawm dov deformation txheej txheem, compression nyob rau hauv lub thickness kev taw qhia yog qhov tseem ceeb deformation. Thaum lub thickness kev taw qhia ntawm lub dov daim yog compressed los ntawm yob, cov hlau yuav ntws longitudinally thiab transversely, tab sis lub longitudinal extension deformation ib txwm zoo heev tshaj qhov transverse expansion. Qhov no yog vim qhov kev sib txhuam ntawm cov yob nto ib txwm cuam tshuam qhov dav dav. Ntau tshaj qhov kev taw qhia longitudinal, uas yog hais tias, piv nrog cov longitudinal kev taw qhia, lub transverse dav yog ib txwm me dua. Lub deformation Performance index thaum dov yog feem ntau:
1) Kev txo qis: Qhia qhov kev hloov pauv ntawm qhov tuab ntawm cov khoom dov ua ntej thiab tom qab dov, uas ua rau kev hloov pauv ncaj qha ntawm qhov sib txawv ntawm tus nqi hauv kev tsim khoom.
2) Tus nqi ua haujlwm: siv los sau cov approximate degree ntawm deformation.
3) Dav: Siv rau ntawm qhov chaw tsim khoom los qhia qhov tseeb ntxiv tus nqi ntawm qhov dav.
Qhov tseem ceeb tshaj plaws tsis muaj kev koom tes hauv qhov chaw tsim khoom yog cov saum toj no. Lwm yam xws li elongation, elongation coefficient, thiab lwm yam tsuas yog rau kev tsom xam. Yog li ntawd, dab tsi yog feem ntau siv rau ntawm qhov chaw yog xam qhov ntev tom qab dov, ua tus nqi, thiab lwm yam raws li lub ntim invariance mob ntawm hlau yas deformation.

FAQ

Q: Koj puas tuaj yeem muab cov qauv?

A: Yog, rau cov qauv loj li niaj zaus yog dawb tab sis tus neeg yuav khoom yuav tsum tau them tus nqi thauj khoom.

Q: Kuv tuaj yeem tau txais cov lus hais los ntawm koj li cas?

A: Koj tuaj yeem tso peb cov lus, thiab peb yuav teb txhua cov lus hauv lub sijhawm. Los yog peb tuaj yeem tham hauv kab los ntawm tus thawj coj ua lag luam. Thiab koj tuaj yeem pom peb cov ntaub ntawv tiv toj ntawm nplooj ntawv tiv tauj.

Q: Koj puas lees txais qhov kev tshuaj xyuas thib peb?

A: Yog lawm peb lees txais.

Q: Hais txog tus nqi khoom?

A: Cov nqi sib txawv ntawm lub sijhawm mus rau lub sijhawm vim kev hloov pauv ntawm tus nqi ntawm cov khoom siv raw.
