Q460NH Weathering Hlau Coils yog engineered rau cov kev siv siab hauvRailway CarriagesthiabCov khoom siv chaw nres nkoj, qhov twg raug rau ya raws, ntsev, thiab dynamic me neeg kho tshuab thauj khoom xav tau tshwj xeeb depability. Ua raws liGB \/ T 4171-2008, cov kauj sib txuas ua ke lub zog siab (ntau dua los yog sib npaug ntawm 460 MPa tawm tswv yim kev tsim qauv uas txhawb nqa kev tsim cov ntom ntom, tiv thaiv-Qhov (Oh)xeb txheej. Lawv cov ntsiab lus carbon qis (tsawg dua los yog sib npaug rau {{0%) kom ntseeg tau tias lub tsheb loj, chaw nres nkoj crane qauv, thiab khoom thauj cov thawv ntim khoom.
Corrosion Kuj Siv Hluav Taws Xob
Nyob rau hauv kev tsheb nqaj hlau thiab chaw nres nkoj, Q460NHnHnh cov ntsiab lus tsim tsim cov khoom tiv thaiv:
Sai sai pata tsim: CU thiab P Pib txoj kev loj hlob ntawm nyias-Qhov (Oh)Txheej tsis pub dhau 3-6 lub hlis, thaiv kev ya raws thiab ntsev ions (curs) los ntawm kev nkag mus rau cov hlau.
Txheej txheej: CR thiab NI tswj lub patina, tiv thaiv kev ua kom zoo thiab txo cov nqi xeb rau1\/8 8th ntawm cov pa roj carbon hlau-as siv tau rau hauv cov tshuaj tsuag ntsev (1, 000+}} sijhawm nrog tsawg dua lossis sib npaug}. 1 hli kev txo poob).
Cov txheej txheem no yog qhov tseem ceeb rau kev tsheb ciav hlau raug cov av noo, de-icing ntsev, thiab cov khoom siv chaw nres nkoj raug rau cov ntug dej hiav txwv.
Cov ntawv thov hauv kev tsheb nqaj hlau & chaw nres nkoj
Railway Carriages:
Lub cev Panels: Resards corrosion los ntawm nag, daus, thiab de-icing tshuaj, txo kev txij nkawm downtime.
Underframe Cheebtsam: Withstands cyclic chaw thau khoom los ntawm tsheb ciav hlau txav thiab cov khoom siv hnyav, raws li pom hauv cov tsheb thauj khoom bogies.
Cov khoom siv chaw nres nkoj:
Crane lug: Txhawb kev lag luam high-load Lifting txheej txheem hauv Salt-Laden Tubrog Apac).
Cov khoom ntim khoom: Tswj txoj kev ncaj ncees hauv av noo, corrosive chaw nres nkoj cia, kev txuas ntxiv ntim khoom siv sia siv nyiaj los ntawm 30-50%.
Piv txwv li: A Suav Railway tuam txhabTxo cov carrosion corrosion los ntawm 60% tshaj 15 xyoos siv Q460NH Coils, piv rau cov hlau tsis muaj.
Kev ua cov lus pom zoo
Vuam: Siv cov hluav taws xob tsawg-hydrogen tsawg (piv txwv li, e 5015- nh) rau cov ntu nyias (<12mm) to avoid hydrogen-induced cracking; preheat thicker sections (≥12mm) to 80–120°C.
Khaub Tawv: Zoo tagnrho rau yob-ua rau hauv cov profiles (piv txwv li, carriage sab panels) vim muaj kev kub ntxhov siab thiab cov khoom siv uas tsis sib haum.
Nto Kho: Cia cov huab cua ntuj rau 3-6 lub hlis los tsim lub Patina ruaj khov; Rau cov ntawv thov pleev xim, thov zinc-primers los txhim kho adhesion rau cov nplaim hluav taws.
