Dab tsi yog cov khoom ntawm crane cov tsheb ciav hlau

Cov khoom siv ntawmCrane railsFeem ntau suav nrog lub zog siab, hnav tsis kam, nkees tsis kam, txhua yam tsim los ua kom tau raws li qhov ntev}}} cov log hnyav, thiab cov haujlwm hnyav} kev thauj khoom.

Ua ntej, muaj zog siab. Crane rail yuav tsum tau withstand concentrated loads los ntawm txhua lub log, nyob deb tshaj plaws dhau ntawm lub tsheb ciav hlau log siab. Cov ntaub ntawv cov ntaub ntawv sib tw feem ntau yog qhov siab- manganese steel (xws liU71mn) lossis alloy steel (xws liU75V). Los ntawm kev siv tshuaj lom neeg tsim qauv thiab kev kho cua sov, cov ntsia ua hauj lwm lub zog, tiv thaiv cov roj hmab hauv qab lub nra hnyav thiab cuam tshuam.
| 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 |
Thib ob, hnav tsis kam. Nquag pib, nres, thiab braking ua rau lub log loj heev - kev tsheb ciav hlau hu rau hnav. Cov taub hau tsheb nqaj hlau feem ntau yog quenched lossis saum npoo-}}} lossis siab dua, kev txhim kho lub neej, thiab tswj kev ua haujlwm txuas ntxiv.
Thib peb, qaug zog tsis kam. Crane rail cov kev sib tw ua kom tau cov khoom ntim ntev ntev ntev dhau - kev ua haujlwm, uas tuaj yeem ua rau qaug zog tawg. Khoom siv tawv thiab hla}}} seemal kev tsim yuav tsum tiv thaiv transculture bracture nyob rau hauv high {4} bi} zaus mus. Thicken lub vev xaib thiab cov hauv paus ntawm cov kev pab faib cov kev ntxhov siab thiab txhim kho ntau dua kev ua kom qaug zog.
Tsis tas li ntawd, crane cov ntaub ntawv cov ntaub ntawv yuav tsum muaj kev sib tsoo txaus thiab ua kom ruaj khov, thiab kev teeb tsa, thaum muaj ntau lub hauv paus xws li pob zeb ua vaj tse lossis pob zeb steel. Rau ib puag ncig tshwj xeeb, anti - corrosion kev kho mob los yog}}}} - tej kev mob kub.
Gnee RailMuab cov cleads hauv ntau cov ntaub ntawv, suav nrog U71MN thiab U75V, thiab anti} Lub ntsej muag sib tsoo, thiab} Cov ntsej muag sib tsoo, luv, thiab kev ua haujlwm ib puag ncig. Txog kev cob qhia thiab xaiv cov kev daws teeb meem, thovTiv Tauj Pebrau kev txhawb nqa.
