Puas yog Tag Nrho Railroad Spikes High Carbon? Cov Qib Khoom Piav Qhia

Txoj kev tsheb ciav hlau dav hlau ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev ruaj ntseg ntawm txoj kev khiav. Nws yog ib tug loj rail ntsia hlau siv rau fastening railway sleepers los yog rail ties rau txoj kev tsheb ciav hlau. Nws cov yam ntxwv pom tseeb - lub taub hau offset thiab tiaj tus -ntug chisel taw tes - pab tus spike tiv thaiv loosening. Txoj kev tsheb ciav hlau yog lub ntsiab lus tseem ceeb ntawm kev tsheb ciav hlau ceev ntawm cov ntoo - pw tsaug zog lem, thiab nws tseem tuaj yeem ua rau hauv kev tsheb ciav hlau dav hlau rau kev ua haujlwm.

Ib lo lus nug ntau los ntawm cov neeg yuav khoom yog seb txhua qhov kev tsheb ciav hlau puas yog siab - carbon steel. Lo lus teb tsis yog. Cov khoom siv yog xaiv los ntawm rooj plaub, raws li cov khoom thauj, hom kab, ib puag ncig thiab qhov yuav tsum tau ua kom ntev. Tsawg-carbon thiab nruab nrab- carbon steels tseem siv dav hauv cov qauv kab, thaum siab -carbon lossis alloy steels feem ntau yog siv rau hnyav- thauj lossis siab - kev tsheb ciav hlau ceev.

Kev faib khoom ntawm kev tsheb ciav hlau spikes

1. Tsawg- carbon steel

Yam khoom siv: Q235 (A3)

Yam ntxwv:nruab nrab lub zog, zoo toughness, tsis tshua muaj nqi ua

Siv tau scenarios:cov qauv kev tsheb ciav hlau, lub teeb- cov kab ua haujlwm, ib ntus lem, thiab ntoo- kab pw tsaug zog

2. Nruab nrab- carbon steel

Yam khoom siv: 35#, 45#, 55#

Yam ntxwv:kuj muaj zog thiab hardness, txaus toughness, muaj zog load- bearing muaj peev xwm

Siv tau scenarios:nruab nrab - thauj railways, hnyav- cov kab tsheb thauj mus los, lossis cov xwm txheej uas yuav tsum tau hnav tsis kam

3. Siab - carbon / alloy steel

Yam khoom siv:40Mn2, 20MnSi

Yam ntxwv:siab zog, siab toughness, zoo hnav tsis kam

Siv tau scenarios:siab- kev tsheb ciav hlau ceev, hnyav- tsheb ciav hlau, kev tsheb ciav hlau, lossis crane rails

Nco tseg:siab - carbon steel spikes yog nquag embrittlement thiab tsis haum rau qhov kub thiab txias heev los yog siab - cuam tshuam ib puag ncig; yog li ntawd, tshav kub-kho los yog alloyed steels feem ntau yog siv los txhim kho toughness.

Qhov kev xaiv cov khoom cuam tshuam li cas rau tus nqi thiab kev ua haujlwm

Rau tus qauv kab kab, Q235 spikes yog kev xaiv kev lag luam thiab tau ua haujlwm rau ntau xyoo. Rau lub mainline nrog hnyav qag loads, 45 # los yog 55 # muab lub hardness ntxiv thiab tuav lub zog xav tau. Rau siab -ceev lossis hnyav- txoj hauv kev taug kev, cov qib alloy xws li 40Mn2 lossis 20MnSi muab lub zog nrog cov tawv tawv uas xav tau kom muaj sia nyob qis qis thiab cuam tshuam yam tsis muaj kev tawg. Kev qhia cov khoom siv los ntawm qhov kev pabcuam tiag tiag - tsis yog los ntawm tus cwj pwm - yog txoj hauv kev zoo tshaj plaws los tswj tus nqi thiab taug qab kev ntseeg tau.

Dab tsi los qhia thaum xaj spikes

Muab cov ntsia hlau loj (dub spike lossis ntsia hlau ntsia hlau loj), qhov ntev thiab lub taub hau daim ntawv, cov khoom siv qib, thiab kev kho deg (plain oiled, zinc plated, kub dip galvanized). Rau cov hlau lossis cov cua sov- kho spikes, hais lub hom phiaj hardness lossis cov cuab yeej cuab tam yog tias daim duab xav tau ib qho.

FAQ

Vim li cas thiaj siab - carbon spikes zam hauv huab cua txias?

High- carbon steel muaj qhov toughness qis ntawm qhov kub thiab txias thiab tuaj yeem tawg nyob rau hauv kev cuam tshuam - piv txwv li thaum ntaus los ntawm lub log derailed los yog thaum txias - huab cua installation. Thaum tshav kub kub-kho lossis alloyed steels rov ua kom tawv thaum ua kom lub zog, yog li lawv tau teev tseg rau qhov txias thiab siab - kev pabcuam cuam tshuam.

Qhov txawv ntawm 45 # thiab Q235 spikes yog dab tsi?

Q235 yog tsawg- carbon structural steel nrog lub zog nruab nrab thiab zoo heev toughness ntawm tus nqi qis; 45# yog qhov nruab nrab- carbon steel nrog lub zog siab dua thiab tawv tawv tom qab kev kho cua sov. 45# tuav tau zoo dua hauv cov khoom hnyav tab sis raug nqi ntau dua thiab nyuaj rau kev tsav tsheb.

Puas tuaj yeem spikes ntawm cov khoom sib txawv tuaj yeem sib xyaw hauv ib ntu?

Nws tsis pom zoo: kev sib xyaw ua ke ua kom muaj kev sib tw tsis sib xws thiab kev saib xyuas nyuaj. Siv ib qib khoom siv rau ib cheeb tsam fastening tshwj tsis yog qhov tsim tshwj xeeb xav tau kev hloov pauv.

Puas yog alloy spikes (40Mn2, 20MnSi) puas tsim nyog tus nqi ntxiv?

Nyob rau siab -ceev, hnyav- tsheb thauj mus los lossis kev lag luam uas muaj qhov tsis sib haum xeeb nres tsheb, yog - alloy lub zog thiab tawv yuav txo qis kev ua haujlwm thiab ncua sijhawm txij nkawm. Ntawm lub teeb- cov kab ua haujlwm, Q235 lossis 45# feem ntau txaus.

Kev kho saum npoo dab tsi tiv thaiv spikes hauv qhov chaw ntub dej?

Kub dip galvanizing los yog zinc plating tiv thaiv lub shank thiab lub taub hau los ntawm corrosion nyob rau hauv cov ntug dej hiav txwv thiab cov av noo. Plain oiled yog tus qauv kev lag luam rau kev pabcuam hauv av qhuav.

Puas yog GNEE RAIL muab spikes hauv tag nrho cov ntaub ntawv no?

Yog lawm. GNEE RAIL muab railway spikes nyob rau hauv Q235, 35 #, 45 #, 40Mn2, 20MnSi thiab lwm yam qib, ua ke nrog ntxiv fasteners xws li rail pads, khi daim hlau, rail clips, ntses daim hlau thiab crane rail clips, thiab txhawb customized tsim, ua thiab installation kev taw qhia.
