GB hnyav ntawm cov hlua hluav taws xob tau tsim cov qauv txheej txheem tshwj xeeb kom sib ntsib sib txawv ntawm cov kev xav tau sib txawv ntawm qhov hnyav {{0} {haul apps. Lawv cov hom phiaj tshwj xeeb tshaj plaws tuaj yeem raug cais los ntawm qhov hnyav thiab lub zog.
1. Cov tub ntxhais kawm hom kev faib tawm los ntawm qhov hnyav rau ib lub ntsuas
Qhov no yog qhov kev kawm tshwj xeeb tshaj plaws, ncaj qha kev txiav txim siab tus pas hla hla- kev thauj khoom {{cov kabmob muaj peev xwm.
Cov kev sib tw ntawm kev sib tw tshaj plaws rau Tuam Tshoj lub teb chaws lub teb chaws kab, siv cov kev caij ceev ceev, thiab cov nroog loj hauv nroog. Nws ua tiav qhov kev ua kom sib npaug ntawm kev ruaj ntseg thiab kav ntev.
Ib qho ntxiv - kev ua haujlwm hnyav tshaj plaws hauv cov tsheb loj heev lossis cov chaw nres nkoj loj los yog cov kev faib khoom loj.
Ib qho kev sib tw hnyav siv rau kev tsheb ciav hlau kab, chaw nres tsheb, marshalding yards, thiab kev kho cov haujlwm rau cov laus nrog cov kev ua haujlwm qis dua. Nws pabcuam ua ib qho tseem ceeb ntxiv thiab tus nqi -} kev xaiv zoo.
2. Kev faib tawm los ntawm cov khoom siv thiab qib siab
Nyob rau hauv tib lub cev yuag tib yam tshwj xeeb, cov nqaj hlau tuaj yeem faib tau txuas ntxiv mus rau cov qib sib txawv ntawm cov tshuaj lom neeg thiab cov txheej txheem kho cua sov. Piv txwv li, tus GB60KG / M Rail nrog cov qhab nia zoo li U71MN (lub zog txheem) thiab U75V (lub zog siab). Alloy Rails zoo li U76CCCRRRRRRE, raws li cov ntug hlau hnyav xws li GB75kg / m, txuas ntxiv txhim kho kev qaug zog thiab tiv thaiv kev nkees.
| Qib hlau | C(%) | Si | Mn | Cr | V | P | S | Tensile Lub Zog (RM / MPA) |
| U71mn | 0.65~0.76 | 0.15~0.58 | 0.70~1.40 | – | – | Tsawg dua los yog sib npaug rau 0.035 | Tsawg dua los yog sib npaug rau 0.030 | Ntau dua los yog sib npaug rau 880 |
| U75V | 0.71~0.80 | 0.50~0.80 | 0.75~1.05 | – | 0.04~0.12 | Tsawg dua los yog sib npaug rau 0.035 | Tsawg dua los yog sib npaug rau 0.030 | Ntau dua los yog sib npaug rau 980 |
| U76Ccrre | 0.71~0.81 | 0.50~0.80 | 0.80~1.10 | 0.25~0.35 | 0.04~0.08 | Tsawg dua los yog sib npaug rau 0.035 | Tsawg dua los yog sib npaug rau 0.025 | Ntau dua los yog sib npaug rau 1080 |
Gnee Rail tau muaj kev txawj ntse hauv cov txheej txheem tshwj xeeb thiab cov qauv txheej txheem ntawm GB hnyav. Peb tuaj yeem muab cov khoom kom raug tag nrho cov khoom lag luam, los ntawm GB50kg / m thiab GB60KG / m rau cov lus qhia ntawm qib (piv txwv li, U71MN, U75V). Txawm hais tias koj qhov project yuav tsum raug nqi-} Cov khoom siv hluav taws xob zoo, peb muaj peev xwm nqa cov khoom lag luam thoob ntiaj teb thiab cov kev daws teeb meem zoo tshaj plaws.Tiv Tauj Pebrau kev txiav nyiaj txhawb nqa.
