Raws li ib feem tseem ceeb ntawm cov txheej txheem nruam nruam, tundish txoj kev ua haujlwm hauv ob sab phlu yuav tsum tau tiv taus qhov scouring thiab yaig ntawm high-temperature molten steel. Cov khoom siv tshuaj siliceous tsis haum rau tam sim no alkaline steelmaking, yog li cov ntaub ntawv alkaline refractory feem ntau yog siv, feem ntau yog cov ntaub ntawv magnesium. Magnesium qhuavramming lojcov khoom muaj qhov zoo ntawm kev tsim kho yooj yim, kev ua haujlwm siab thermal, siab slag plhaub tshem tawm tus nqi, thiab lub neej ua haujlwm ntev, thiab tau txais txiaj ntsig los ntawm kev lag luam steel smelting.
Txoj kev loj hlob
1. Raw khoom xaiv:
Magnesium raw cov ntaub ntawv: feem ntau fused magnesia thiab sintered magnesia, uas muaj siab refractoriness thiab corrosion kuj.
Binder: Ib txwm siv phenolic resin binders yog qhov ua rau muaj kuab paug ib puag ncig thiab kim, yog li nws yuav tsum tau nrhiav ntau tus phooj ywg ib puag ncig thiab kev lag luam binders thaum lub sijhawm txhim kho. Cov kev tshawb fawb tau pom tias sodium metasilicate heptahydrate tuaj yeem siv los ua cov ntaub ntawv tseem ceeb thiab siv nrog phenolic resin los txhim kho kev ua haujlwm ntawm cov khoom siv thiab txo cov pa phem ib puag ncig.
2. Particle grading:
Los ntawm kev kawm txog kev cuam tshuam ntawm qhov sib txawv particle grading ntawm qhov ntom ntom ntawm magnesium qhuav ramming mass, qhov zoo dua particle grading scheme yog txiav txim siab.
Lub tswv yim muab cov khoom zoo dua tuaj yeem ua rau cov ntim ntim ntawm cov ntaub ntawv qhuav siab dua, yog li txhim kho lawv cov kev tiv thaiv kev ua haujlwm thiab tiv thaiv kev yaig.
3. Cov txheej txheem npaj:
Cov khoom siv magnesium qhuav yog npaj los ntawm kev vibration molding txheej txheem. Los ntawm kev tswj tsis tau xws li kev vibration siab thiab lub sijhawm, cov khoom qhuav muaj qhov ntom ntom zoo dua thiab lub zog.
Thaum lub sij hawm kev npaj, nws yog ib qho tsim nyog yuav tsum nruj me ntsis tswj tsis xws li qhov sib tov sib xyaw, sib tov lub sij hawm thiab kub ntawm cov ntaub ntawv raw kom ruaj khov thiab txhim khu kev qha ntawm cov khoom qhuav.
Kev ntsuas kev ua tau zoo thiab kev ua kom zoo
1. Kev ntsuas kev ua tau zoo: Cov tsim magnesium qhuav ramming loj yog kuaj rau kev ua tau zoo, suav nrog kev tiv thaiv scouring, anti-erosion, thermal shock stability, thiab lwm yam.
2. Optimization thiab txhim kho:
Raws li kev ntsuas kev ua tau zoo, cov khoom siv raw piv, particle grading thiab kev npaj cov txheej txheem yog optimized thiab txhim kho. Los ntawm kev nruam iteration thiab optimization, kev ua tau zoo ntawm cov tsim magnesium qhuav cov khoom yog superior thiab ua tau raws li cov kev xav tau ntawm steel smelting kev lag luam.
Piv nrog rau cov tsoos magnesium qhuav ramming cov ntaub ntawv, ib puag ncig tus phooj ywg qhuav cov ntaub ntawv muaj kev ua tau zoo ib puag ncig thiab cov txiaj ntsig kev lag luam. Kev siv cov ntaub ntawv zoo ib puag ncig tuaj yeem txo cov nqi tsim khoom, txhim kho kev tsim khoom, thiab txo cov pa phem ib puag ncig.
