Ferroalloy yog ib qho tseem ceeb ntawm cov khoom siv hlau thiab siv dav hauv kev tsim khoom. Cov txheej txheem ntau lawm ntawm ferroalloys feem ntau muab faib ua ob pawg: smelting txoj kev thiab electrochemical txoj kev. Ntawm lawv, txoj kev smelting ua tau ntau dua ntawm ferroalloys thiab yog kev lag luam ntau dua.
Lub tshuab ferroalloy smelting yog cov paub tab thiab cov txheej txheem ntws tau ruaj khov, uas feem ntau muab faib ua plaub yam: kev npaj raw khoom, txheej txheem smelting, alloy muaj pes tsawg leeg hloov thiab cov khoom ua.
ferroalloy txheej txheem smelting
Raw khoom npaj
Cov ntaub ntawv tseem ceeb ntawm ferroalloys yog ores thiab hlau cov ntaub ntawv, xws li kaolin, montmorillonite, hlau ore, thiab lwm yam. Cov ntaub ntawv raw yuav tsum tau crushed, soj ntsuam, sib tov thiab lwm yam txheej txheem los xyuas kom meej lub uniformity thiab fluidity ntawm raw cov ntaub ntawv.
Tsis tas li ntawd, ferroalloy smelting tseem yuav tsum tau ntxiv cov khoom siv xws li fluxes thiab txo cov neeg ua haujlwm rau cov khoom siv raw kom nce cov ntsiab lus melting, txhim kho fluidity thiab txhim kho cov nyhuv txo. Kev xaiv thiab ntxiv tus nqi ntawm cov khoom pabcuam no yuav tsum tau kho raws li qhov xwm txheej tshwj xeeb.
01
Smelting txheej txheem
Cov txheej txheem smelting ntawm ferroalloy smelting yog qhov txuas tseem ceeb tshaj plaws. Tam sim no, muaj ntau txoj kev smelting xws li blast furnace smelting thiab hluav taws xob rauv smelting. Ntawm lawv, blast furnace smelting yog txoj kev siv ntau tshaj plaws.
Nyob rau hauv blast furnace smelting, raw cov ntaub ntawv yog pretreated thiab ces muab tso rau hauv lub cub tawg kom undergo cov tshuaj tiv thaiv xws li txo thiab deoxidation los tsim hlau alloys. Nyob rau hauv cov txheej txheem no, yam xws li smelting kub, cua, lub sij hawm, zoo, thiab lwm yam yuav tsum tau nruj me ntsis tswj los xyuas kom meej qhov zoo thiab tso zis ntawm ferroalloy.
02
Kho cov alloy muaj pes tsawg leeg
Cov smelted hlau alloy feem ntau xav tau kev hloov kho ntxiv. Hauv cov txheej txheem no, cov ntsiab lus carbon, silicon cov ntsiab lus, cov ntsiab lus ntawm manganese thiab lwm cov ntsiab lus alloying tuaj yeem tswj tau hauv ferroalloy los ntawm kev ntxiv lwm cov ntsiab lus, nce qhov kub, thiab lwm yam kom tau raws li daim ntawv thov kev xav tau hauv ntau qhov chaw.
03
Kev tuav khoom
Tom qab ferroalloy smelting tiav lawm, cov khoom tseem yuav tsum tau ua thiab ua tiav kom tau raws li kev lag luam xav tau. Feem ntau hais lus, ferroalloys yuav tsum tau crushing, tshuaj ntsuam, cia thiab lwm yam txheej txheem los xyuas kom meej cov khoom zoo thaum txhim kho ntau lawm efficiency.
