Dab tsi yog qhov rail bolt?
Rail bolts, tseem hu ua rail bolts los yog rail thauj tog rau nkoj bolts, yog siv los ruaj ntseg ntsia hlau los yog lub hauv paus phaj rau cov neeg pw tsaug zog. Rail bolts yog bolts uas tau muab tso rau hauv lub qhov nyob rau hauv lub sleepers thiab muaj ib tug funnel txiv ntoo uas tom rau hauv qab ntawm lub sleeper.
Rail bolts yog ib hom kev muaj zog, siab-corrosion-resistant fasteners uas tau siv dav hauv kev tsheb ciav hlau, txuas hniav, tsim cov qauv hlau thiab lwm yam. Lawv tau tsim tshwj xeeb thiab ua los ntawm cov hlau zoo. Tom qab kev kho cua sov, quenching, tempering thiab lwm yam txheej txheem, lawv muaj lub zog siab, siab hardness thiab zoo hnav tsis kam. Rail bolts kuj muaj kev tiv thaiv corrosion zoo thiab tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev hauv qhov chaw hnyav.

1. Lub zog siab thiab hardness: rail bolts yog ua los ntawm cov hlau muaj zog thiab muaj zog heev thiab hardness tom qab kev kho cua sov, thiab tuaj yeem tiv taus cov khoom loj thiab siab.
2. Zoo hnav tsis kam: rail bolts yuav tsum tau tiv taus lub zog hnyav thiab kev sib txhuam ntawm cov tsheb ciav hlau hauv kev siv txhua hnub, thiab lawv cov kev hnav zoo heev tuaj yeem ua haujlwm ruaj khov mus ntev.
3. Kev tiv thaiv corrosion zoo heev: rail bolts muaj kev tiv thaiv corrosion zoo thiab tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev hauv qhov chaw hnyav, txo cov nqi tu.
4. Precision manufacturing thiab nruj zoo tswj: cov txheej txheem ntawm rail bolts nruj me ntsis raws li kev lag luam cov qauv, adopts precision manufacturing txheej txheem thiab nruj zoo tswj los xyuas kom meej qhov zoo thiab kev ua tau zoo ntawm cov khoom.
Nrog rau kev txhim kho txuas ntxiv ntawm kev lag luam thev naus laus zis, rail bolts yuav siv rau hauv ntau qhov chaw, muab kev txhawb zog rau kev txhim kho kom ruaj khov ntawm txhua qhov chaw ntawm lub neej.
