Yuav ua li cas induction melting rauv cam khwb cia steel pob?

Cov pob hlau nrum tuaj yeem muab faib ua peb pawg suav nrog cov pob chromium siab, cov khoom nruab nrab chromium thiab cov khoom tsis tshua muaj chromium.

1. Qhov Performance index ntawm siab chromium pob

Cov ntsiab lus chromium ntawm lub siab chromium pob yog ntau dua lossis sib npaug li 10.0%. Cov ntsiab lus carbon yog nruab nrab ntawm 1.80% thiab 3.20%. Raws li lub teb chaws tus qauv, lub hardness ntawm lub siab chromium pob yuav tsum tsis muaj tsawg tshaj li 58hrc, thiab qhov cuam tshuam tus nqi yuav tsum ntau tshaj los yog sib npaug zos rau 3.0j / cm2. Yuav kom ua tiav qhov hardness no, lub siab chromium pob yuav tsum tau quenched thiab tempered ntawm qhov kub thiab txias. Tam sim no, muaj ob txoj hauv kev rau quenching siab chromium npas hauv Suav teb, suav nrog roj quenching thiab cua quenching. Yog hais tias qhov kev xeem hardness ntawm lub siab chromium pob yog qis dua 54HRC, nws txhais tau hais tias nws tsis tau quenched.

2. Qhov Performance index ntawm nruab nrab chromium pob

Cov ntsiab lus chromium ntawm nruab nrab chromium pob yog li ntawm 3.0% mus rau 7.0%, thiab cov ntsiab lus carbon yog nyob nruab nrab ntawm 1.80% thiab 3.20%. Nws tus nqi cuam tshuam yuav tsum tsis pub tsawg dua 2.0j / cm2. Lub teb chaws cov qauv xav kom lub hardness ntawm lub pob chrome yuav tsum siab tshaj los yog sib npaug rau 47hrc. Txhawm rau kom ua tau zoo, cov khoom nruab nrab chromium yuav tsum tau tempered ntawm qhov kub thiab txias kom tshem tawm cov kev ntxhov siab.

Yog hais tias qhov saum npoo ntawm lub pob steel yog xim dub thiab xim liab, nws ua pov thawj tias lub pob steel tau raug kev kub ntxhov los ntawm kev kub ntxhov. Yog hais tias qhov saum npoo ntawm lub pob steel tseem muaj cov xim hlau, peb tuaj yeem txiav txim siab tias lub pob steel tsis tau txais kev kho qhov kub thiab txias.

3. Qhov Performance index ntawm tsawg chromium pob

Feem ntau hais lus, cov ntsiab lus chromium ntawm lub pob chromium tsawg yog 0.5% txog 2.5%, thiab cov ntsiab lus carbon yog los ntawm 1.80% mus rau 3.20%. Yog li ntawd, raws li lub teb chaws tus qauv, lub hardness ntawm tsawg chromium pob yuav tsum tsis muaj tsawg tshaj li 45hrc, thiab qhov cuam tshuam tus nqi yuav tsum tsis pub tsawg tshaj li 1.5j / cm2. Cov khoom uas tsis tshua muaj chromium kuj xav tau kev kho kub kub kom ntseeg tau zoo. Qhov kev kho no tuaj yeem tshem tawm kev ntxhov siab. Yog hais tias qhov saum npoo ntawm lub pob steel yog tsaus liab, nws qhia tau hais tias nws tau dhau los ntawm kev kub siab tempering. Yog tias qhov saum npoo tseem yog xim hlau, nws txhais tau hais tias lub pob steel tsis tau tempered ntawm qhov kub thiab txias.

Cam khwb cia hlau npas feem ntau yog siv nyob rau hauv ntau yam cement nroj tsuag, tshuaj nroj tsuag, fais fab nroj tsuag, quartz xuab zeb nroj tsuag, silica xuab zeb nroj tsuag, thiab lwm yam rau loj-scale mining.
