Rail Hardening Tshuab

A. Khoom nta

1. Induction cua sov tsis xav kom cua sov ua haujlwm tag nrho, tab sis tuaj yeem xaiv cov cua sov ib feem, thiaj li ua tiav lub hom phiaj ntawm kev siv hluav taws xob tsawg, thiab kev hloov pauv ntawm cov haujlwm tsis pom tseeb.

2. Cov cua sov ua kom nrawm nrawm, uas tuaj yeem ua rau lub tshuab ua haujlwm ncav cuag qhov xav tau kub hauv lub sijhawm luv luv, txawm tias tsis pub dhau 1 thib ob. Raws li qhov tshwm sim, qhov oxidation saum npoo av thiab decarburization ntawm cov ua haujlwm yog qhov me me, thiab feem ntau ntawm cov ua haujlwm tsis xav tau kev tiv thaiv roj.

3. Cov txheej tawv tawv tuaj yeem hloov kho thiab tswj tau los ntawm kev kho qhov ua haujlwm zaus thiab lub zog ntawm cov cuab yeej raws li xav tau. Raws li qhov tshwm sim, cov txheej txheem martensite ntawm txheej tawv tawv yog qhov zoo dua, thiab qhov tawv, lub zog thiab tawv yog qhov siab.

4. Tom qab kev kho cua sov ntawm txoj kev siv cua sov ua kom sov, cov khoom ua haujlwm muaj cov tuab tuab tuab nyob hauv qab txheej tawv txheej, thiab muaj qhov ua kom zoo dua qub kev nyuab siab, uas ua rau cov khoom ua haujlwm tiv taus qaug zog thiab tawg.

5. Cov khoom siv cua sov yooj yim rau teeb tsa ntawm kab kab tsim khoom, yooj yim kom paub txog kev siv tshuab thiab kev siv tshuab yooj yim, tswj tau yooj yim, tuaj yeem txo qis kev thauj mus los, txuag neeg ua haujlwm, thiab txhim kho kev ua haujlwm tau zoo.

6. Ib lub tshuab tuaj yeem siv rau ntau lub hom phiaj. Nws tuaj yeem ua tiav cov txheej txheem kho cua sov xws li quenching, annealing, tempering, normalizing, thiab quenching thiab tempering, ntxiv rau vuam, zom, sib dhos ua cua sov, tshem tawm cua sov, thiab cua sov los ntawm kev tsim.

7. Yooj yim siv, yooj yim rau kev khiav lag luam, thiab tuaj yeem pib lossis nres thaum twg los tau. Thiab tsis tas yuav tsum tau preheat.

8. Nws tuaj yeem ua haujlwm ntawm tus kheej, ib nrab thiab ua haujlwm tau zoo; nws tuaj yeem ua haujlwm tsis tu ncua rau lub sijhawm ntev, lossis nws tuaj yeem siv tau ntawm qhov xwm txheej thaum nws siv. Nws muaj txiaj ntsig zoo rau kev siv cov cuab yeej siv thaum lub sijhawm luv nqi luv nqi hluav taws xob.

9. Kev siv hluav taws xob siab, kev tiv thaiv ib puag ncig thiab kev txuag hluav taws xob, kev nyab xeeb thiab kev ntseeg tau, thiab kev ua haujlwm zoo rau cov neeg ua haujlwm, uas tau hais los ntawm lub xeev.
