Raws li cov khoom tseem ceeb rau kev thauj mus los ntsug ntawm cov chaw tsim khoom, kev nyab xeeb thiab ruaj khov yog nyob ntawm cov khoom xaiv. Kev siv cov ntaub ntawv tseem ceeb tsis tsuas cuam tshuam rau lub neej ntawm cov khoom siv tab sis kuj yog kev nyab xeeb ntawm cov neeg ua haujlwm.
Cov Txheej Txheem Hlau Txheej Txheem Hlau
Lub ntsiab ntawm kev tsim kev txhim kho ntawm Q235B lossis Q345B lossis Q345B tsawg {} {{3} {lub zog steel. Hom hlau no muaj cov khoom siv tshuab ua kom zoo dua, muaj zog ntawm vendability, thiab zoo nkauj heev, ua kom nws lub zog ua haujlwm thiab zoo li qub tsim tawm thaum lub sijhawm ua haujlwm. Cov ntu txheem (ntu ntu), cov ntu kev txhawb nqa ntsug ntawm txoj kev xav, feem ntau welded los ntawm square lossis round leeg. Lub raj raj phab ntsa tuab yog feem ntau 4-8 mm los xyuas kom meej tag nrho cov qauv kev ruaj khov.
Kis thiab thauj khoom - cov kabmob sib txuas
Qhov tseem ceeb tuaj yeem sib kis xws li cov kev qhia qhia thiab racks feem ntau yog tsim ntawm 45 # steel lossis 20mntib alloy qauv hlau. Tom qab quenching thiab tempering tshav kub, lub saum npoo hardness tuaj yeem ncav cuag hrc35 {{4 {{{{}} Terme Kev sib kis tau raug. Cov Hlua Hlau, ua haujlwm raws li kev txhawb nqa ntsug rau lub ntsuas hluav taws xob, feem ntau yog ua los ntawm 6 × 19 lossis 8 × 19 strand hloov tso nyiaj steel hlua. Ua los ntawm cov pa roj carbon ntau zoo ntawm cov hlau, nws tau khav theeb lub zog ntawm 1570 MPa lossis 1770 MPA, ua kom muaj kev nyab xeeb ua haujlwm hauv kev ua haujlwm hnyav.
Kev Tiv Thaiv thiab Txuas Cov Cheebtsam
Kev nyab xeeb yam xws li kev tiv thaiv kev tiv thaiv thiab cov txheej txheem cus yog feem ntau ua los ntawm cov nplooj ntawv txias}}}}} 3, muab ob qho kev siv xeb tsis kam thiab lub zog. Cov kev sib txuas xws li bolts thiab pins feem ntau yog tsim los ntawm 40Crmo hlau, tempered thiab nto-hardened los xyuas kom muaj zog thiab nkees ua yeeb yam.
Corrosion tiv thaiv thiab kev kho deg
Txhawm rau txuas lub neej pabcuam, cov hlau loj feem ntau yog txhaj tshuaj tiv thaiv kom xeb thiab tom qab ntawd muab tso rau epoxy zinc thiab acrylic polyurethane topcoat. Hloov chaw, kub - dip galvanizing yog siv nyob rau hauv ib puag ncig corrosive loj xws li cheeb tsam ntug dej hiav txwv kom corrosion tsis kam.
Hauv cov ntsiab lus, cov khoom xaiv ntawm kev siv cov hoists yuav tsum coj mus rau hauv tus account lub zog, kev ua tsis taus, hnav tsis kam thiab corrosion tsis kam. Los ntawm kev tshawb fawb txog kev tshawb fawb thiab kev kho cov txheej txheem, kev ua haujlwm nyab xeeb thiab txhim khu kev qha thiab txhim khu kev qha thiab txhim khu kev qha thiab txhim khu kev ua haujlwm nyob rau hauv cov kev ua haujlwm nyuaj.
