Dab tsi yog rail elastic clip?
Rail elastic clipyog siv los fasten cov ntsia hlau rau hauv qab phaj phaj ua ke nrog cov pob zeb pw tsaug zog. Feem ntau rail clips yog ua los ntawm forged caij nplooj ntoos hlav steel uas yog tsim los ntawm kub forging txheej txheem. Vim hais tias ntawm cov niaj hnub microstructure ntawm forged clips, nws yog suav hais tias yuav zoo dua lwm yam hlau txoj kev.
GNEEmuab ntau yam kev tsheb ciav hlau clips nrog qhov zoo tshaj plaws, cov tsheb ciav hlau clips no yog tsim los nrog kev ua haujlwm siab thiab ua los ntawm cov qib siab zoo caij nplooj ntoos hlav steel. GNEE RAIL yog qhov loj tshaj plaws thiab muaj kev sib tw ntau tshaj plaws ntawm kev tsheb ciav hlau clip hauv Suav teb tom qab ntau tshaj 18 xyoo rail clip tsim kev paub, thiab muaj peev xwm los sib tw hauv teb chaws loj thiab nruab nrab scaled rail tej yaam num. Dab tsi ntxiv, peb txoj kev tsheb ciav hlau tuaj yeem hloov kho raws li cov neeg siv khoom xav tau.
Dab tsi yog qhov hardness ntawm rail elastic clip?
Lub hardness ntawm rail elastic clip feem ntau yog los ntawmHRC 42-47, raws li kev qhia tshwj xeeb rau ntau hom xws li E2007 thiab E2055. Qee qhov kev ua haujlwm siab -kev ua tau zoo, xws li Nabla clips, tej zaum yuav muaj zog dua ntawmHRC 51-55.
- Standard hardness:Qhov feem ntau hardness specification rau elastic rail clips yog HRC 42-47. Qhov no feem ntau yog qhov yuav tsum tau ua rau clips ua los ntawm cov qib steel caij nplooj ntoos hlav zoo li60 Si2MnA.
- Ntau hardness variants:Qee qhov tshwj xeeb ntawm cov hlua khi hlua khi, xws li Nabla clips, yog tsim los kom muaj qhov tawv tawv dua ntawm HRC 51-55 los muab kev txhim kho clamping.
- Cov qauv zoo:Lub hardness yog ib qho kev ntsuam xyuas zoo, nrog rau cov yam ntxwv xws li qaug zog lub neej thiab qhov seem deformation, kom ntseeg tau tias clips ua tau raws li lawv lub neej kev pab cuam.

Dab tsi yog txoj haujlwm ntawm kev tsheb ciav hlau clip?
- Hloov cov quab yuam sab nraud los ntawm txoj kev tsheb ciav hlau mus rau hauv cov phaj steel thiab cov qauv
- Ruaj ntseg lub tsheb ciav hlau nyob rau hauv lub lateral kev taw qhia kom txo tau pad creep
- Siv lub zog ntsug ntawm txoj kev tsheb ciav hlau txhawm rau txhawm rau cov ntsaws ruaj ruaj ntawm lub ncoo
GNEE RAILMuaj ntau hom kev tsheb ciav hlau fasteners kom tau raws li cov neeg siv khoom xav tau, xws li Elastic Rail Clip thiab Clamp, Rail Screw Spike, Yas Dowel, High Tensile Track Bolt nrog txiv ntseej, Rail Base (Tie) Phaj, Rail Fish Phaj, Rail Lub xub pwg (Ntxig), Ntses Bolt, Railroad Rubber thiab EVA Pad, thiab lwm yam.
