Cov menyuamyog cov kauj ruam tseem ceeb tshaj plaws hauv kevtxheej txheem tsim khoom txiasYog li ntawd, cov khoom siv xaiv rau lub menyuam kuj yog ib qho tseem ceeb hauv kev txiav txim siab qhov zoo ntawm adov txoj kev tshuab. Kev xaiv cov khoom siv sib txawv ntawm cov menyuam yuav ua rau muaj qhov sib txawv loj ntawm qhov zoo ntawm cov ntaub ntawv thiab ntawm tus nqi tsim khoom. Hauv kev lag luam tshuab dov hauv Suav teb, cov khoom siv ntawm cov menyuam feem ntau muab faib ua cov hom hauv qab no: 45 hlau, 45 hlau electroplated nrog Cr, GCr15, Cr12, Cr12MOV, thiab lwm yam.
Ntau lub chaw tsim khoom kuj tseem yuav hloov cov menyuam mus rau cov hlau cam khwb cia kom txuag tau tus nqi. Cov neeg yuav khoom yuav tsum ua tib zoo paub qhov txawv thaum koj yuav cov tshuab. Vim muaj cov ntsiab lus hlau sib txawv ntawm cov tshuaj lom neeg C, Cr, MO, V, thiab lwm yam ntawm ntau hom khoom siv saum toj no, kev ua tau zoo thiab tus nqi sib txawv heev, yog li daim ntawv thov hauv kev tsim khoom kuj txawv. Rau cov kauj vuam ib txwm muaj lub zog tso zis tsawg dua 330Mpa thiab qhov tuab tsawg dua 1.5 hli, xws li cov ntawv kub dov, cov ntawv txias dov, PPGI, hlau galvanized, 45 hlau lossis 45 hlau chromed tuaj yeem ua tau raws li qhov yuav tsum tau ua. Txhawm rau tiv thaiv cov menyuam kom tsis txhob xeb thiab ua kom lub neej ua haujlwm ntev ntawm cov menyuam, Linbay Machinery siv cov txheej txheem chrome plating rau txhua 45 hlau rollers (chrome plating thickness yog 0.05 hli), thiab qhov nyuaj tom qab kev kho cua sov tuaj yeem ncav cuag 58-62HRC, uas yog kwv yees li tib yam li qhov nyuaj ntawm Cr12 thiab GCr15. Thaum txo cov nqi, nws tau txais cov khoom zoo tib lub sijhawm. Yog tias koj xav tsim cov kauj hlau muaj zog nrog lub zog tso zis ntau dua 350Mpa lossis cov kauj hlau tsis xeb, Linbay Machinery yuav xaiv GCr15 lossis Cr12 ua cov khoom siv rau cov menyuam, uas kim dua. Ob yam khoom siv no muaj kev tiv thaiv kev hnav ntau dua, kev ruaj khov thermal thiab lub zog compressive, kev ua tau zoo heev. Ntawm lawv, Cr12 Cheebtsam yog sib npaug rau American Standard D3. Ntxiv nrog rau kev siv ua cov khoom siv dov, Cr12 kuj tseem siv ua cov khoom siv punch, tuag, thiab ntxig. Cov khoom siv zoo tshaj plaws ntawm cov menyuam yog Cr12Mov lossis Japanese standard SKD11 lossis American standard D2, uas kim heev piv rau lwm tus, nws muaj kev tiv thaiv kev hnav siab thiab muaj lub neej ua haujlwm ntev tshaj plaws. Ntxiv nrog rau kev siv ua cov khoom siv dov, Linbay Machinery feem ntau siv cov khoom siv no rau kev txiav hniav.
Qhov tseem ceeb tshaj plaws, koj tuaj yeem xaiv cov khoom siv rau cov menyuam raws li koj cov kev xav tau thiab cov peev nyiaj. Linbay Machinery yuav ib txwm muab cov kev daws teeb meem zoo tshaj plaws rau koj cov kev xav tau tshwj xeeb, yog li koj tuaj yeem yuav lub tshuab ua ntawv yob zoo tshaj plaws.
