Hluav taws xob rauv txheej txheem ua haujlwm
1. Kev tswj cov smelting ib puag ncig
Nyob rau hauv lub cub hluav taws xob ntau lawm ntawm high carbon ferromanganese, kev tswj ntawm smelting ib puag ncig yog ib qho tseem ceeb heev. Cov txheej txheem hluav taws xob rauv smelting yuav tsum muaj qee qhov redox ib puag ncig, uas yog qhov tsim nyog rau kev txo cov tshuaj tiv thaiv thiab tsim cov slag. Nyob rau tib lub sijhawm, kev saib xyuas yuav tsum tau them nyiaj ntxiv rau qhov tsim nyog ntawm limestone kom stabilize cov tshuaj muaj pes tsawg leeg ntawm slag, uas muaj txiaj ntsig zoo rau kev tiv thaiv phab ntsa rauv thiab txhim kho cov hlau zoo.
2. Kev tswj qhov kub thiab txias
Lub melting kub ntawm high carbon ferromanganese yog feem ntau ntawm 1500-1600 ℃. Rau kev txo qis thiab melting ntawm manganese ore, qee qhov kub thiab txias yuav tsum tau mus txog. Nws raug pom zoo tias cov cua kub hauv pem hauv ntej ntawm lub cub tawg yuav tsum tswj tau ntawm ib ncig ntawm 100 ° C, uas tuaj yeem txo lub sij hawm melting.
3. Kev hloov kho ntawm alloy muaj pes tsawg leeg
Cov alloy muaj pes tsawg leeg yog ncaj qha ntsig txog qhov zoo thiab tus nqi ntawm cov khoom. Los ntawm kev ntxiv cov khoom siv raw thiab kho qhov kev faib ua feem, cov ntsiab lus ntawm manganese, carbon, silicon thiab lwm yam khoom tuaj yeem tswj tau zoo. Ntau dhau impurities yuav cuam tshuam qhov zoo ntawm ferromanganese thiab txawm tsim los ntawm cov khoom.
Cov cuab yeej tu thiab tswj kev nyab xeeb
1. Kev tu cov khoom siv hluav taws xob rauv taws
Kev saib xyuas ntawm cov hluav taws xob furnaces muaj qhov cuam tshuam tseem ceeb ntawm kev tsim khoom thiab khoom siv lub neej. Tsis tu ncua xyuas cov khoom siv hluav taws xob, cov ntaub ntawv rwb thaiv tsev, cables, dej txias thiab lwm yam khoom siv, thiab hloov thiab kho lawv raws sijhawm kom ntseeg tau tias cov cuab yeej ua haujlwm zoo.
2. Kev tswj hwm kev nyab xeeb ntau lawm
Kev tswj hwm kev nyab xeeb ntawm kev tsim khoom kuj tseem yog ib feem tseem ceeb ntawm cov txheej txheem smelting. Thaum lub sij hawm smelting, cov qauv kev tiv thaiv kev nyab xeeb yuav tsum tau ua raws li, cov khoom siv tiv thaiv yuav tsum tau hnav, thiab kev nyab xeeb ntawm lub qhov cub yuav tsum tau kuaj xyuas. Kev saib xyuas kuj yuav tsum tau them nyiaj rau kev tiv thaiv kev sib tsoo xws li slag ntws, hluav taws kub, thiab lub qhov ncauj qhov cub tawg.
Cov khoom tuav thiab ruaj khov
Tom qab kev npaj cov pa roj carbon ntau ferromanganese, yog tias xav tau kev lim dej ntxiv lossis kev sib cais ntawm lwm cov ntsiab lus, nws tuaj yeem nkag mus lossis smelted. Cov txheej txheem ua tiav cov kua roj carbon monoxide ferromanganese yuav tsum tau muab cia rau hauv lub thawv tshwj xeeb kom tsis txhob muaj kev cuam tshuam oxidation. Nyob rau tib lub sijhawm, kev saib xyuas yuav tsum tau them rau ib puag ncig kev huv thiab kev tswj hwm roj kom tsis txhob muaj roj.
Nyob rau hauv luv luv, zus tau tej cov high-carbon ferromanganese los ntawm hluav taws xob rauv txoj kev yog ib tug complex txheej txheem uas yuav tsum tau scientific thiab tsim nyog cov kauj ruam kev khiav hauj lwm thiab nruj kev ruaj ntseg ntsuas. Tsuas yog los ntawm kev tswj hwm qhov chaw melting thiab melting kub, kho qhov sib piv ntawm cov khoom siv raw, thiab kev tswj xyuas cov cuab yeej thiab kev tswj xyuas kev nyab xeeb tuaj yeem tsim cov khoom zoo, high-purity high-carbon ferromanganese cov khoom kom tau raws li cov kev xav tau ntawm kev lag luam.
