Cov ntaub ntawv dab tsi ua rau Railway Rail Guide Phaj?

Cov khoom xaiv ntawmTxoj Kev Rail Guide Plates(railway gauge baffles) ncaj qha txiav txim siab lawv cov load- bearing peev, durability, thiab adaptability. Lawv feem ntau yog categorized rau hauv cov ntaub ntawv hlau thiab tsis yog -cov ntaub ntawv hlau, nrog rau tag nrho cov ntaub ntawv uas yuav tsum tau ua raws li thoob ntiaj teb thiab domestic kev lag luam qauv xws li UIC, AREMA, BS, thiab GB los xyuas kom meej muaj kev ruaj ntseg nrog cov khiav fastener system.

Cov khoom siv hlau yog cov khoom siv dav tshaj plaws. Ntawm lawv, Q235 zoo tib yam carbon structural steel yog qhov kev xaiv zoo tshaj plaws rau cov qauv yooj yim vim nws tus nqi siab -kev ua tau zoo. Nrog cov tshuaj muaj pes tsawg leeg ntawm C Tsawg dua lossis sib npaug li 0.22%, Mn Tsawg dua lossis sib npaug li 1.4%, thiab Si Less dua lossis sib npaug li 0.35%, nws muaj lub zog tensile ntawm 370-500MPa thiab kev ua haujlwm txias txias zoo heev. Ua tiav los ntawm kev kub dov, nws tuaj yeem ua tau raws li cov khoom siv niaj hnub-cov kabmob uas yuav tsum tau ua ntawm cov kab tsheb ciav hlau zoo tib yam. 65Mn caij nplooj ntoos hlav steel, nrog lub zog siab dua, hardness, thiab elasticity, yog tsim rau hnyav{15}} cov ntu nrog cov kev xav tau siab rau kev hnav tsis kam thiab cuam tshuam. Cov pa roj carbon nruab nrab xws li C35 thiab C45 tau ua kom zoo dua lub zog thiab tawv tom qab kev kho cua sov, ua rau lawv cov khoom siv rau nruab nrab - mus rau - siab - kawg gauge baffles. Cov hlau hlau kuj tseem nyob hauv txoj haujlwm tseem ceeb: QT500-7 muaj Brinell hardness ntawm 180-220HB thiab lub zog tensile ntawm Ntau dua lossis sib npaug rau 500MPa, haum rau cov khoom thauj thiab cov neeg caij tsheb zoo tib yam; QT600-3 muaj qhov ua kom tawv tawv ntawm 220-250HB thiab feem ntau yog nruab nrog cov hlua txuas ntxiv kom ua tau raws li cov kev xav tau hnyav ntawm kev kub ceev railways lossis cov kab hnyav.

Tsis yog- cov khoom siv hlau feem ntau yog cov nylon reinforced. Cov ntaub ntawv xws li PA6+GF30 thiab PA66, tom qab ntxiv 30% iav fiber ntau, tau txhim kho cov neeg kho tshuab lub zog, hnav tsis kam, thiab kev ua haujlwm rwb thaiv tsev. Lawv tau tsim tshwj xeeb rau cov kab khiav nrog cov kev cai tshwj xeeb rwb thaiv tsev kom tsis txhob muaj kev cuam tshuam hauv kev sib tw.

GNEEmuab ntau yam ntawm Railway Rail Guide Phaj npog tag nrho cov ntaub ntawv saum toj no, suav nrog ntau yam tshwj xeeb thiab qauv xws li 3#, 6#, 10#, 13#, 14#, thiab 20#, uas tuaj yeem phim ntau lub tshuab fastener (Type Ⅰ, Hom Ⅱ, Hom Ⅲ, thiab lwm yam) thiab 5{7 10 kg / m. Lub caij no, GNEE muab cov kev txhawb nqa ua tiav xws li cov hlua khi hlua khi, cov hlua khi, thiab cov hlua tsheb ciav hlau yas, ua raws li cov qauv zoo thoob ntiaj teb hauv kev tsim khoom. Nws kuj tseem muaj cov kev daws teeb meem raws li cov kab sib txawv ua haujlwm, nrog rau kev cob qhia kev teeb tsa kev tshaj lij thiab kev pab cuam kho mob ntev ntev, muab ib qho - nres thiab tag nrho - lub neej voj voog nrawm txhawb kev pabcuam rau kev khiav haujlwm engineering.
