Kev xaiv raw khoom
Qhov zoo ntawm railway spikes yog ze ze rau lawv cov khoom siv raw thiab kev tsim khoom. High-cov kev tsheb ciav hlau zoo yog feem ntau yog ua los ntawm cov pa roj carbon nruab nrab lossis cov pa roj carbon siab kom ntseeg tau tias lawv muaj zog txaus thiab tensile lub zog. Ua ntej smelting cov hlau, cov tshuaj muaj pes tsawg leeg yuav tsum tau soj ntsuam nruj me ntsis kom ntseeg tau tias cov proportions ntawm cov ntsiab lus xws li carbon, manganese, sulfur thiab phosphorus ua tau raws li cov qauv kev lag luam railway. Cov ntsiab lus carbon teeb tsa lub zog thiab hardenability, thiab cov sulfur thiab phosphorus raug tswj kom qis qis kom khaws cov toughness.
Blanking thiab cua sov
Thaum lub sij hawm tsim khoom, cov spikes yog thawj zaug ua ntej - kho los ntawm cov txheej txheem blanking thiab cua sov. Lub steel bar yog sheared rau hauv blanks ntawm qhov yuav tsum tau ntev, thiab cov blanks yog rhuab mus rau lub forming kub. Cov cua sov yog tswj los tsim kom muaj qhov sib txawv ntawm qhov kub thiab txias, uas yog qhov ua ntej rau kev ua kom zoo ib yam thiab rau qhov zoo ntawm metallurgical zoo ntawm cov pob txha tiav.
Forging: Kub Forging thiab Cold Heading
Cov spikes yog ces tsim los ntawm kub forging los yog txias taub hau. Kub forging tuaj yeem txhim kho qhov sib xws ntawm cov qauv ntawm cov khoom siv hauv cov khoom thiab txhim khu kev cuam tshuam, vim tias cov txheej txheem forging refines cov nplej thiab aligns lawv nrog cov duab ntawm cov ntsia hlau loj. Lub taub hau txias txhim kho qhov ua tiav ntawm qhov kawg thiab qhov tseeb ntawm cov spikes, ua kom lub ntsej muag du thiab nruj nreem tswj. Txoj kev tsim yog xaiv los ntawm hom spike thiab cov khoom yuav tsum tau ua.
Kev kho cua sov
Tom qab tsim, cov spikes feem ntau yuav tsum tau kho cua sov, xws li quenching thiab tempering, txhim khu lawv toughness thiab hardness. quenching hardens cov hlau los ntawm kev txias sai, thiab tempering txo cov brittleness thiab teeb tsa qhov kawg tshuav ntawm lub zog thiab ductility. Cov kev kho cua sov tsis yog tswj los tsim cov hardness thiab toughness xav tau los ntawm cov lus qhia tshwj xeeb.
Kev kho saum npoo
Thaum kawg, kev tiv thaiv corrosion yog txhim kho los ntawm cov txheej txheem kho saum npoo xws li kub-dip galvanizing, Dacromet txheej lossis kev kho oxidation dub. Txoj kev kho saum npoo tiv thaiv qhov ntsia hlau loj los ntawm corrosion nyob rau hauv ib puag ncig kev pab cuam, thiab txheej txheej thiab thickness yog xaiv los ntawm daim ntawv thov. Qhov chaw kho mob kuj txhim kho qhov tsos thiab kev tuav ntawm cov khoom.
Kev Tswj Xyuas Zoo
Tag nrho cov txheej txheem tsim khoom yuav tsum nruj me ntsis ua raws li ISO kev tswj hwm kev tswj hwm zoo thiab sib txuas cov kev tshuaj xyuas qhov ntev, kev sim hardness, ntsuas cov cuab yeej siv tshuab thiab lwm yam txheej txheem los xyuas kom meej tias txhua qhov kev sib tw ua tau raws li lub teb chaws lossis thoob ntiaj teb cov qauv kev tsheb ciav hlau. Cov ntaub ntawv zoo muab cov traceability uas yuav tsum tau rau railway supply, thiab txhua batch yog sau nrog cov qhabnias xeem.
