1.Vim li cas txias -rolled coils tsis siv tau?
Txoj kev tsheb ciav hlau khiav tawm yog ib qho tseem ceeb tshaj plaws, nyuaj, thiab cuam tshuam -cov kabmob ntawm cov kab ke, suav nrog kev hloov tsheb, qav, lub taub hau ntawm cov tsheb ciav hlau, thiab kev xa tawm. Lawv tso siab heev xav tau ntawm cov ntaub ntawv:
Lub zog siab heev thiab tawv heev: Lawv yuav tsum tau tiv taus qhov hnyav hnyav hnyav, cuam tshuam, thiab qaug zog los ntawm lub tsheb ciav hlau log. Qhov no feem ntau yuav tsum muaj qhov nruab nrab - mus rau siab - carbon steel lossis alloy steel, thiab qhov tsim nyog microstructure (piv txwv li, sorbite) thiab cov khoom siv tshuab ua tiav los ntawm forging, dov (feem ntau yog kub dov), thiab kev kho cua sov (xws li, quenching thiab tempering).
Kev hnav zoo heev: Cov kev hloov tsheb thiab cov qav muaj kev hnav hnyav heev, xav tau cov khoom siv uas hnav heev - tiv taus.
Txaus thickness thiab ntoo khaub lig-sectional dimensions: Ntau yam turnout Cheebtsam yog tuab thiab loj los xyuas kom meej rigidity thiab load- bearing muaj peev xwm.
2.Dab tsi yog cov kev txwv ntawm txias -rolled coils?
Cov khoom siv feem ntau yog qis- carbon steel: Cold-rolled coils feem ntau yog siv rau kev sib sib zog nqus nqus thiab sib sau. Lawv cov khoom siv raw (xws li SPCC thiab SPCE) muaj cov pa roj carbon tsawg, thiab lawv lub zog thiab qhov tawv tawv yog qis dua qhov yuav tsum tau ua rau cov khoom sib tw.
Cov txheej txheem ua rau muaj kev sib txawv ntawm cov kev taw qhia: Cov txheej txheem txias dov feem ntau txhim kho qhov chaw tiav, qhov tseeb qhov tseeb, thiab hardness (ua hauj lwm hardening), tab sis txi cov khoom plasticity thiab toughness. Rau kev sib tw ua rau muaj kev cuam tshuam loj, tsis txaus toughness yog qhov tuag taus.
Thickness txwv: Txias- dov coils yog nyias nyias (feem ntau nyob rau hauv ob peb millimeters), uas tsis tuaj yeem ua tau raws li qhov xav tau ntawm cov khoom sib tw.
3.Dab tsi yog cov ntaub ntawv thiab cov txheej txheem rau kev tsim cov khoom lag luam?
Core load-cov kabmob cov kabmob: Cov no yog ua los ntawm cov hlau tshwj xeeb (xws li siab -manganese steel lossis bainitic steel), tsim los ntawm forging lossis kub dov, ua raws li kev ua haujlwm siab thiab kev kho cua sov. Piv txwv li, siab -manganese steel qav muaj qhov hnav tsis kam thiab cuam tshuam.
Cov khoom siv sib txuas: xws li cov ntaub qhwv, cov ntawv swb, thiab cov hlua khi, feem ntau yog ua los ntawm kub- dov steel phaj (nruab nrab- cov phaj tuab) los ntawm kev txiav, drilling, thiab vuam. Lub zog thiab toughness ntawm kub- dov daim hlau yog tsim nyog rau daim ntawv thov no.
4.Dab tsi yog daim ntawv thov scenarios rau txias -rolled coils hauv kev lag luam railway?
Locomotive thiab dov cov khoom lag luam: Siv rau lub cev, tawv nqaij, cov khoom siv sab hauv (xws li cov corrugated flooring), thiab cov khoom zoo nkauj ntawm cov neeg caij tsheb thiab cov tsheb thauj khoom. Qhov no yog vim nws qhov zoo ntawm qhov zoo, yooj yim ntawm kev pleev xim, thiab kev zoo nkauj zoo nkauj.
Cov khoom siv hluav taws xob thiab cov thawv tswj: Cov vaj tsev rau kev teeb tsa kev tsheb ciav hlau thiab cov khoom siv hluav taws xob.
Tsis yog -load-cov kabmob sab hauv cov khoom: Cov hnab nqa taug kev, cov vaj huam sib luag, thiab lwm yam, hauv cov tsheb thauj khoom.
Muaj peev xwm "indirect" lossis "auxiliary" siv cov txias -rolled coils hauv cheeb tsam turnout:
Kev tiv thaiv npog lossis cov vaj huam sib luag zoo nkauj: Siv los npog vaj tsev ntawm cov chaw tsav tsheb (switches), thiab tsis yog - cov khoom siv.
Ntim los yog gaskets: Tej zaum yuav siv tau los ua kev tiv thaiv ib ntus lossis kho cov shims thaum lub sij hawm thauj mus los lossis kev teeb tsa, thiab tsis ua rau cov qauv zaum kawg.
5.Dab tsi yog yam uas txwv tsis pub?
Tsis txhob siv cov khaub thuas zoo tib yam- dov qis- cov pa roj carbon steel coils ncaj qha los tsim cov tub ntxhais thauj khoom- cov kabmob ntawm cov tsheb ciav hlau (hloov, qav, thiab lwm yam), vim qhov no yuav ua rau muaj kev nyab xeeb loj heev.
