Compound deoxidizer yog qhov ntau heevdeoxidizer. Piv nrog rau cov deoxidizer zoo tib yam, cov nyhuv deoxidation ntawm composite deoxidizer yuav zoo dua. Composite deoxidizer hais txog ob lossis ntau dua deoxidizers, uas tuaj yeem txhim kho hlau.
Feem ntausilicon aluminium barium calcium, silicon calcium, silicon carbon alloy, thiab lwm yam., txoj kev siv yog ntxiv cov saum toj no composite deoxidizer rau molten steel thaum pib ntawm steel tapping thaum lub sij hawm steel tapping txheej txheem, mas manually.
Composite deoxidizers feem ntau siv calcium, txhuas, magnesium, silicon thiab lwm yam khoom rau deoxidation, feem ntau yog vim muaj kev sib raug zoo ntawm cov ntsiab lus nrog oxygen. Composite deoxidizers feem ntau yog siv vim qee cov khoom deoxidation kuj yuav ua rau ib leeg los tsim ib co eutectics, ntxiv txo cov kev ua ntawm oxidation cov khoom, thiab ua rau cov deoxidation cov tshuaj tiv thaiv ntxiv, uas yog, optimize lub deoxidation nyhuv.
Composite deoxidizer deoxidation tuaj yeem tsis tsuas yog muab kev ua si tag nrho rau cov nyhuv deoxidation ntawm cov deoxidizers muaj zog, tab sis kuj hloov cov khoom siv deoxidation, txhim kho fluidity ntawm molten steel, thiab txhim kho cov purity ntawm molten steel, thiab kev siv cov nyhuv yog zoo kawg li. Nyob rau tib lub sijhawm, cov khoom lag luam tsis tsuas yog muaj tag nrho cov haujlwm ntawm cov deoxidizers yav dhau los, tab sis kuj tuaj yeem siv rau hauv molten steel refining furnaces thiab theem nrab deoxidation sib sib zog nqus, nrog rau cov teebmeem tseem ceeb, uas tuaj yeem hloov cov tshuaj calcium carbide deoxidation.
Cov deoxidizers sib txawv muaj cov yam ntxwv sib txawv. Thaum siv, deoxidizer yuav tsum raug xaiv raws li qhov tseeb daim ntawv thov kom tsis txhob nqa cov impurities tshiab rau cov hlau molten. Koj yuav tsum paub tias qee qhov sib xyaw deoxidizers kuj muaj impurity tshem tawm cov ntsiab lus, xws li aluminium composite deoxidizers, uas tuaj yeem ntxuav cov impurities xws li sulfur thiab phosphorus hauv cov hlau molten, uas yuav pab tau zoo rau kev txhim kho cov hlau. Yog tias koj xav paub ntau ntxiv, koj tuaj yeem tiv tauj peb.
