Cov ntaub ntawv siv rau Rail Spike Manufacture
Yeej, kev tsheb ciav hlau spikes yog tsim los ntawm cov qib carbon thiab alloy steel. Cov khoom siv feem ntau yog Q235 carbon steel, Q345B thiab Q345D carbon steel, 45 steel, 40Cr alloy steel, 35CrMoA alloy steel thiab 20MnTiB boron steel. Txhua qib muaj qhov sib npaug sib txawv ntawm lub zog, toughness, formability thiab weldability, yog li qhov kev xaiv cov khoom yuav tsum ua kom haum rau qhov kev pabcuam ntawm qhov ntsia hlau loj.
Cov khoom ntawm Common Steel Qib
Q235 carbon hlau
Q235 carbon steel nta cov khoom yas zoo, tawv thiab vuam kev ua tau zoo, thiab nws kuj muaj qhov txias txias thiab khoov tus cwj pwm. Q235 yog ib txwm siv rau qhov chaw thiab cov qauv welded nrog cov kev xav tau nruab nrab, thiab nws yog ib qho kev xaiv rau dev spikes ntawm lub teeb kab uas lub load yog nruab nrab.
45 carbon hlau
45 steel yog cov feem ntau siv nruab nrab carbon steel, nrog cov khoom zoo txhua yam. Nws yog ib qho yooj yim tawg thaum nias txias, yog li cua sov feem ntau yog siv rau hauv kev ua haujlwm . 45 steel yog dav siv rau kev tsim cov khoom txav nrog lub zog siab dua, xws li lub zog, shafts thiab cov hniav, thiab nws kuj yog cov khoom siv rau lub taub hau ntsia hlau square.
Q345 carbon hlau
Q345 carbon steel muaj cov cuab yeej zoo txhua yam thiab kev ua haujlwm zoo nrog rau txias thiab kub nias, nrog rau zoo corrosion kuj. Nws feem ntau yog siv rau hauv cov khoom siv welded nrog kev thauj khoom siab, xws li cov nkoj, boilers, lub nkoj siab, cov roj tank, txuas hniav, cov cuab yeej siv hluav taws xob thiab cov cranes. Rau kev tsheb ciav hlau spikes, Q345 qib muaj zog dua li Q235 qhov twg txoj kev xav tau lub cev muaj zog dua.
40Cr alloy hlau
Tom qab txias, 40Cr steel muaj cov cuab yeej zoo txhua yam thiab zoo toughness nyob rau hauv qis kub cuam tshuam. Nws cov cuab yeej vuam tsis zoo thiab nws yooj yim tawg thaum vuam, tab sis nws yog ib qho ntawm cov hlau alloy feem ntau siv, pom muaj nyob rau hauv lub zog, shafts, worms, tes tsho, pins, rods, screws, bolts thiab li qub. Rau rail spikes, 40Cr yog siv nyob rau hauv qhov chaw siab zog thiab hardenability yuav tsum tau, piv txwv li nyob rau hauv high- lub zog ntsia hlau spike chav kawm.
35CrMoA thiab 20MnTiB Steel
35CrMoA yog chromium molybdenum alloy steel nrog lub zog siab thiab zoo toughness, haum rau hnyav- lub luag haujlwm fasteners uas yuav tsum tiv taus qaug zog thiab cuam tshuam . 20MnTiB yog boron steel nrog zoo hardenability, feem ntau siv rau siab - lub zog bolts vim boron txhim kho cov nqi ntawm cov hlau. Ob qib tso cai rau spikes thiab bolts kom ncav cuag cov khoom vaj khoom tsev siab dua uas xav tau los ntawm kev thov cov ntawv thov taug qab.
Dog Spikes vs Ntsia Hlau Spikes thiab Cov Khoom Xaiv
Feem ntau hais lus, muaj ob hom rail spikes, aub spikes thiab ntsia hlau spikes, thiab lawv txawv ob qho tib si hauv cov duab thiab kev ua haujlwm. Dog spikes yog siv los khi txoj hlua khi rau cov ntoo, nrog rau lub taub hau L- zoo li lub taub hau thiab lub ntsej muag lub ntsej muag, thaum ntsia hlau spikes siv cov xov kom muaj zog tuav hauv cov pw tsaug zog. Thaum xaiv cov khoom siv, xav txog hom kev pw tsaug zog, kev thauj mus los, ib puag ncig thiab cov chav kawm uas yuav tsum tau muaj. Rau lub teeb ntoo sleeper kab, Q235 lossis 45 steel aub spikes yog kev lag luam; rau hnyav- cov kab tsheb thauj mus los, xaiv 45 steel, 40Cr lossis siab dua cov qib alloy nrog kev kho kom haum rau qhov sib xyaw ua ke nrog kev tiv thaiv corrosion.
Kev Ntseeg Tsis Zoo
Ib qho kev xav tsis zoo yog tias cov ntsiab lus carbon ntau dua ib txwm ua kom zoo dua qub. Hauv kev xyaum, cov khoom siv yuav tsum tau ua kom haum rau hom kev pw tsaug zog thiab kev teeb tsa, vim tias cov hlau hnyav dhau tuaj yeem tawg thaum tsav tsheb thiab nyuaj rau khoov lossis tshem tawm. Lwm qhov kev xav tsis zoo yog tias hlau alloy yog ib txwm tsim nyog. Rau cov kab teeb ntawm cov ntoo pw, cov pa roj carbon monoxide xws li Q235 lossis 45 steel muab kev ua haujlwm txaus ntawm tus nqi qis dua, thaum cov qib alloy yuav tsum tau tshwj tseg rau hnyav -haul, turnout thiab siab - cov ntaub ntawv siv zog uas lawv cov nqi raug tsim nyog.
FAQ
