Raws li lub npe qhia, deoxidizer rau steelmaking yog deoxidizer siv nyob rau hauv cov txheej txheem steelmaking. Nws yog feem ntau ntxiv rau molten steel kom ntseeg tau tias du casting thiab dov rau hauv cov hlau tsim nyog. Qee tus nqi ntawm deoxidizer yog siv rau deoxidation, thiab qhov tsim nyog ntawm cov hlau yog ntxiv los kho cov tshuaj muaj pes tsawg leeg kom ua tau raws li qib steel specifications.
Kev faib tawm ntawm Deoxidizers rau Steelmaking:
Silicon-manganese alloy, ferrosilicon, ferromanganese, silicon-calcium alloy, silicon-aluminium-barium-calcium, thiab lwm yam, feem ntau siv;
Lub hom phiaj ntawm Deoxidizer:
1. Nws yog tsim rau deoxidation ntawm ntau yam steelmaking ntau lawm, tshwj xeeb tshaj yog haum rau deoxidation ntawm converter steelmaking ntau lawm. Nws muaj zog deoxidation thiab desulfurization nyhuv, tuaj yeem hloov cov kua dej ntawm cov hlau molten zoo, thiab daws qhov teeb meem ntawm nodules.
2. Txo cov roj cov ntsiab lus ntawm cov hlau thiab txo tus naj npawb ntawm cov inclusions hauv molten steel. Lub hauv paus ntsiab lus yog tias calcium nyob rau hauv cov khoom tuaj yeem hloov cov oxides hauv cov hlau molten rau hauv cov khoom deoxidation nrog cov ntsiab lus melting tsawg uas ntab yooj yim, purifying cov hlau molten. Tsis tas li ntawd, cov txheej txheem siv ntawm cov khoom no yog qhov yooj yim, qhov sib ntxiv ntawm cov alloy yog nce, thiab cov khoom siv alloy tuaj yeem txo qis. , txo tus nqi ntawm steel raw khoom. Thiab txhawm rau txhim kho cov khoom zoo, nws cov txiaj ntsig kev lag luam thiab kev sib raug zoo yog qhov tseem ceeb. Thaum siv rau hauv hluav taws xob furnaces raws li ib tug txo deoxidation, nws muaj peev xwm hloov silicon hmoov, silicon, txhuas thiab barium, zoo heev txo tus nqi ntawm steel smelting.
Yuav Siv Lub Deoxidizer Rau Steel Smelting:
1. Tus nqi ntawm cov khoom ntxiv yog txiav txim siab los ntawm cov ntsiab lus carbon ntawm cov hlau molten zaum kawg, feem ntau yog 1.0-1.5 kg / t ntawm steel.
2. Ntxiv txoj kev: Ntxiv ncaj qha rau hauv qab ntawm lub hnab ua ntej nchuav.
3. Ntxiv ferromanganese, ferrosilicon, thiab txhuas li niaj zaus thaum tshem tawm 1/4 ntawm cov hlau. Lub deoxidizer rau steelmaking muaj zog deoxidation thiab desulfurization nyhuv, thiab tuaj yeem hloov cov kua dej ntawm cov hlau molten zoo.
