Raw cov ntaub ntawv ntawm insulated rail pob qij txha
Insulated rail pob qij txha, feem ntau hu ua fishplates, ua tshwj xeeb fasteners rau kev sib txuas rail xaus ua ke. Cov khoom siv no tau ua tib zoo tsim hauv cov chaw tsim khoom los ntawm cov txheej txheem thermal, kom ntseeg tau tias cov ntaub ntawv rwb thaiv tsev npog tag nrho cov khoom siv hlau los lav qhov kev sib cais hluav taws xob. Hauv Suav teb, lawv cov khoom tsim ua raws li lub teb chaws tus qauv GB11265-89. Feem ntau, lawv yog forged los ntawm cov ntaub ntawv zoo li cov pa roj carbon zoo tib yam kub dov Q235-A, Q255-A, lossis QT400-18, thaum qee cov khoom siv ncaj qha los ntawm cov khoom sib xyaw.
Kev faib tawm raws li cov ntaub ntawv nthuav tawm:
Q235: Hlau muaj pes tsawg leeg (raws li kev soj ntsuam smelting) poob qis los yog sib npaug 15kg / m thiab tshaj 15kg / m.
Hais txog cov qauv, lawv yuav tsum ua raws li cov cai ntawm Q235-A (los yog Class 3B steel) thiab Q255-A hauv GB700, lossis hom 4B steel, raws li.
Ntawm ntau yam insulated fishplates, ib hom tseem ceeb sawv tawm, tsim los ntawm lub zog siab, alkali-dawb iav fiber ntau impregnated epoxy resins, fabricated siv high-temperature forming tuag. Cov iav tsis muaj alkali-dawb fiber ntau tus qauv tsim thiab kev suav cov tshuab ua kom nws muaj zog, muaj cov xov paj ncaj nraim thiab muaj kev xav tsis tu ncua hauv ntau yam kev teeb tsa. Cov insulated fishplates no tau txais kev ntsuam xyuas kev ua haujlwm zoo thiab hluav taws xob hauv lub hoobkas, tsuas yog cov khoom tsim nyog tawm hauv qhov chaw. Tam sim no, railway tivthaiv manufacturers nyob rau hauv Tuam Tshoj tau adeptly mastered no technology.
