Yuav ua li cas faib cov coefficients txuas ntxiv ntawm txhua qhov ntawm Ib Leeg Stand Multi-Groove Txo Rolling Mill tsim nyog

        Tag nrho cov grooves ntawm aIb leeg Stand Multi-groove Txo Rolling Millqhia tib lub yob teeb, sawv ntsug thiab lub ntsiab tsav. Ntau lub raj yog dov ib txhij. Tsis zoo li multi-stand nruam sizing mills, nws tsis muaj kev ywj pheej sawv ceev hloov kho kom them nyiaj sib txawv ntawm cov grooves. Yog li ntawd, lub hauv paus ntsiab lus tseem ceeb ntawm elongation faib yog kom cov hlau ntws zoo ib yam rau txhua qhov zawj. Unbalanced elongation kev faib tawm yuav ua rau lub raj tawg, pawg-up, khawb thiab qhov ntev ntawm qhov ua siab ntev.

Basic kev faib nyiaj

       Qhov sib npaug volumetric flow rate yog thawj txoj cai. Nyob rau tib lub yob ceev, cov khoom ntawm qhov chaw hla ntu thiab elongation coefficient yuav tsum nyob ze rau txhua qhov zawj.

       Lub elongation coefficient ntawm txhua qhov zawj yuav tsum tsis txhob sib txawv ntau dhau. Kev txwv los ntawm kev sib tw rigidity, yob elastic deformation thiab tsis sib luag groove hnav, qhov sib txawv ntawm cov grooves uas nyob ib sab yuav tsum khaws cia me me. Cov grooves nrog nyuaj deformation tau qis elongation, thaum cov grooves nyob rau hauv cov xwm txheej zoo tuaj yeem siv sij hawm ntau dua elongation.

       Elongation ntawm tus kheej zawj tsis tuaj yeem tshaj qhov kev txwv ntawm cov khoom. Rau stainless hlau thiab hlau alloy nrog siab deformation kuj, ib leeg-pass elongation yuav tsum tau txo. Cov pa roj carbon steel raj tuaj yeem txais cov txiaj ntsig zoo dua. Kev sib kis ntawm qhov profile yuav tsum tau txiav txim siab kom tsis txhob muaj fins thiab folds.

Yam tseem ceeb uas yuav tsum tau xav txog thaum faib

       1. Groove txoj hauj lwm: Grooves ntawm qhov chaw nruab nrab thiab ob sab ntawm lub rooj muag zaub muaj qhov sib txawv ntawm qhov sib txawv thiab txias txias. Sab grooves yog nquag mus rau unbalanced load, yog li lawv elongation yuav tsum tsis txhob muab siab heev.

       2. Cov khoom tuaj yeem kam rau ua: Yog tias lub raj xa tuaj rau ib qhov zawj muaj cov phab ntsa tsis zoo lossis ovality, nws cov coefficient elongation yuav tsum raug txo kom tsis txhob buckling thiab sab hauv folds.

       3. Roll hnav nyiam: Cov grooves sab nrauv feem ntau hnav sai dua. Cov nyiaj pub dawb yuav tsum tau tshwj tseg hauv kev tsim qauv. Roll gap hloov yog nyiam rau kev them nyiaj es tsis txhob hloov loj ntawm elongation faib.

       4. Cov khoom siv thauj khoom: Rolling load los ntawm tag nrho cov grooves ua rau tib qho chaw sawv ntsug thiab spindle. Tag nrho cov torque yuav tsum tau kuaj xyuas dua li ntawm ib qho groove load los tiv thaiv lub cev muaj zog overload thiab sawv deflection.

Tej yam tsis zoo tshwm sim los ntawm kev faib tsis tsim nyog

       Ntau dhau elongation ntawm ib zawj: lub raj yog dhau-stretched, nws yuav ua rau caj dab, tawg thiab nyias phab ntsa.

       Tsis txaus elongation ntawm ib zawj: qeeb hlau ntws ua rau pawg-up, raj khawb, yob cim thiab loj txheej txheej.

       Kev sib txawv loj ntawm cov grooves: Kev sib nrig sib cuam tshuam ntawm cov hlab, tsis zoo ntawm qhov sib xws thiab tsis ruaj khov batch zoo.

Hauv qhov chaw kho cov tswv yim

       Elongation yog ua ntej faib thaum lub sij hawm dhau kev tsim. Tom qab kev sim dov, txheej txheej, phab ntsa tuab, qhov chaw saum npoo thiab lub cev muaj zog tam sim no ntawm txhua qhov zawj raug kaw. Rau grooves nrog siab tam sim no thiab nquag tawg, txo elongation. Rau cov grooves uas tsis tshua muaj tam sim no thiab loj lub raj, me ntsis nce elongation los yog kho yob qhov sib txawv.

       Fine tuning ntawm yob qhov sib txawv yog nyiam. Tus thawj elongation faib cov txheej txheem ntawm kev tsim dhau yuav tsum tau khaws cia kom deb li deb tau.
