Cov Khoom Ntawm High Carbon Ferrochrome

 

High chromium cam khwb cia hlau yog hais txog cov hlau cam khwb cia dawb nrog cov ntsiab lus chromium (feem ntau) ntau dua 12%. Nws yog ib qho ntawm feem ntau siv hnav-resistant cam khwb cia hlau hauv tsev thiab txawv teb chaws.

 

High chromium cam khwb cia hlau yog lub thib peb tiam ntawm dawb cam khwb cia hlau tsim los ntawm zoo tib yam tus kheej-cam khwb cia hlau thiab nickel hard cam khwb cia hlau. Nyob rau hauv lub teb chaws tsim nyob rau hauv lub xyoo 1960 thiab nyob rau hauv thaum ntxov 1980s nyob rau hauv kuv lub teb chaws, nyob rau hauv thiaj li yuav ua tau raws li cov kev xav tau ntawm ntau lawm thiab daim ntawv thov ntawm induction furnaces maj mam nrov, siab chromium cam khwb cia hlau nkag mus rau ib tug dav siv theem. Vim yog cov yam ntxwv ntawm cov qauv hlau ntawm high-chromium cam khwb cia hlau, high-chromium cam khwb cia hlau muaj ntau dua toughness, high-temperature zog, tshav kub tsis kam thiab hnav tsis kam tshaj li qub cam khwb cia hlau. dav siv. Rau cov ntawv thov nyob rau hauv ib txwm thiab kub cuam tshuam rau hnav, siab chromium cam khwb cia hlau muaj txiaj ntsig zoo dua.

 

Classic siab chromium cam khwb cia hlau yog Cr15M03. Nrog rau txoj kev loj hlob ntawm ntau lawm, raws li kev tswj ntau yam ntawm Cr cov ntsiab lus, peb series ntawm Cr15, Cr20 thiab Cr25 feem ntau yog siv. Txhawm rau ua kom tau raws li qhov xav tau ntawm kev ua haujlwm sib txawv, ntxiv rau kev kho cov ntsiab lus carbon, lwm yam alloying ntsiab lus, xws li npib tsib xee, tungsten, molybdenum, thiab lwm yam, tau ntxiv los ua ntau cov hlau alloy high-chromium cam khwb cia hlau.

 

Lub as-cam matrix ntawm siab chromium cam khwb cia hlau zoo ib yam li cov hlau tsis muaj cua sov thiab yog austenitic. Cov cam khwb cia hlau nrog cov qauv no yog siv los ntawm qhov kub thiab txias, uas tuaj yeem muab kev ua si tag nrho rau lub peev xwm ntawm cov khoom nws tus kheej. Raws li kev xav tau, los ntawm kev kho cua sov, siab chromium cam khwb cia hlau tuaj yeem tau txais martensitic matrix lossis multi-phase composite matrix qauv.

 

Ntau yam high-chromium cam khwb cia hlau nrog ntau yam muaj pes tsawg leeg muaj lawv tus kheej cov khoom thiab sib xws ntawm kev siv. Tsuas yog thaum cov khoom siv ua tau raws li cov txheej txheem tshwj xeeb tuaj yeem siv nws lub peev xwm thiab ua tiav cov txiaj ntsig zoo tshaj plaws.

 

Cov khoom sib txawv thiab cov kev hloov pauv ntawm cov chromium cam khwb cia hlau siab nyob rau hauv ntau yam kev mob muaj qee yam kev cai, tab sis vim muaj ntau yam cuam tshuam, ntau yam kev hloov kho tau raug coj los siv rau hauv qhov kev xeem, thiab ib qho kev hloov pauv rau kev tshawb fawb. Qhov kev xyaum tsuas yog txheeb ze, yog li yuav muaj qee qhov kev hloov pauv tsis tu ncua hauv cheeb tsam. Tsis tas li ntawd, qhov ntau ntawm chromium thiab carbon uas muaj nyob rau hauv high-chromium cam khwb cia hlau yog qhov dav, thiab qhov ntau ntawm Cr / C yuav tsum tau xaiv yog qhov loj, thiab qhov rhiab heev los ntawm kev xaiv sib txawv muaj zog. Yog li ntawd, cov xwm txheej ua haujlwm yuav tsum tau txiav txim siab tag nrho los pab txhawb kev xaiv cov kev tshawb fawb tsim nyog thiab ua tiav cov txiaj ntsig zoo tshaj plaws. Vim yog qhov tsis zoo ntawm cov khoom siv chromium cam khwb cia hlau, cov naj npawb thiab cov kev tshawb fawb kev sim kuj raug txwv.

 

 

Nyob rau hauv qhov tseeb ntau lawm, thaum muaj ntau yam hnav-resistant spare qhov chaw yog hnav los ntawm loj sinter, pob zeb ore, coke thiab lwm yam abrasives, slippage, khawb, txiav, sib tsoo thiab txawm chiseling yog superimposed rau ib leeg. Cov kev ua haujlwm sib txawv, cuam tshuam rau lub zog, qhov kub thiab txias, thiab lwm yam kuj tseem muaj kev cuam tshuam zoo rau kev hnav cov ntaub ntawv. Yog li ntawd, cov txheej txheem hnav cov ntaub ntawv yog qhov nyuaj.

 

Kev ua haujlwm nyuaj ua rau muaj ntau yam kev xav tau rau cov khoom siv, tshwj xeeb tshaj yog cov khoom siv hlau, uas feem ntau yuav tsum tau ua kom sov, hnav tsis kam thiab cuam tshuam rau tib lub sijhawm, yog li cov chromium cam khwb cia hlau siab yuav tsum tau tsim kom tau raws li cov cai no. Txhawm rau kom siv tag nrho lub luag haujlwm ntawm chromium, carbon thiab lwm yam alloying ntsiab lus, tsim, txhim kho thiab ua qauv siv cov chromium cam khwb cia hlau hauv cov khoom siv hlau, nws yog ib qho tsim nyog yuav tsum kawm txog microstructure, qauv, ntau yam khoom siv thiab cov cua sov. Kev kho cov txheej txheem ntawm high chromium cam khwb cia hlau ntawm cov ntaub ntawv sib txawv Ua tiav kev tshawb fawb kom tau txais cov lus xaus ntawm cov ntsiab lus yooj yim, tsis muaj thiab ntau yam kev cai sib cuam tshuam ntawm daim ntawv thov ntawm high-chromium cam khwb cia hlau nyob rau hauv high-temperature cuam tshuam hnav tej yam kev mob; Ua kom nkag siab tob txog cov xwm txheej hauv paus rau kev siv cov ntsiab lus alloying kom ua rau daim ntawv thov ntawm high-chromium cam khwb cia hlau tsim nyog
