Cov Cib Refractory Zoo Tshaj Plaws rau AOD Furnaces - Hom, Cov txiaj ntsig & Daim Ntawv Thov

Lub cub tawg AOD (Argon Oxygen Decarburization) yog cov khoom siv tseem ceeb rau kev tsim cov hlau tsis xeb thiab cov hlau sib xyaw tshwj xeeb. Cov chaw ua kom huv ntawm AOD muaj qhov kub thiab txias heev, kev hloov pauv kub hnyav, kev xeb alkaline slag muaj zog, thiab kev puas tsuaj ntawm lub tshuab. Cov xwm txheej ua haujlwm hnyav no ua rau AOD lub cub tawg cib ua ib qho ntawm cov khoom siv tseem ceeb tshaj plaws rau cov nroj tsuag hlau. Kev xaiv cov cib ua kom huv uas tsim nyog ncaj qha ua rau lub neej ua haujlwm ntawm cov ntaub hauv lub cub tawg ntev dua, txo cov nqi hloov cov cib ua kom huv, thiab txhim kho kev tsim khoom tag nrho ntawm kev ua hlau.

Yog tias koj tab tom nrhiav cov khoom siv refractory uas ruaj khov thiab pheej yig rau AOD cov hlab, kev nkag siab txog cov hom cib refractory AOD tseem ceeb yog qhov tseem ceeb. Hauv qab no peb qhia txog cov cib refractory uas siv dav tshaj plaws thiab ua tau zoo tshaj plaws rau AOD lub cub tawg.

Cov cib magnesia chrome uas sib txuas ncaj qha yog cov khoom siv txheej txheem ib txwm muaj thiab txhim khu kev qha tshaj plaws rau AOD qhov cub tawg. Tsim los ntawm kev siv cov magnesia fused magnesia thiab chrome ore uas muaj kev ntshiab siab los ntawm kev sintering kub siab, cov cib no muaj qhov tsis tshua muaj porosity, qhov loj me, thiab kev tiv taus slag zoo heev. Lawv tiv taus alkaline steel slag erosion thiab kev poob siab thermal ntau zaus, uas yog ib txwm muaj nyob rau hauv AOD refining txheej txheem. Zoo tagnrho rau cov qhov tseem ceeb hnav siab suav nrog AOD qhov cub tawg slag kab, thaj chaw tuyere thiab phab ntsa ua haujlwm txheej, cov cib refractory no tiv thaiv tau cov txheej txheem spalling thiab kev puas tsuaj nkag mus.

Cov cib magnesia calcium, tseem hu ua dolomite refractory cib, tau dhau los ua cov khoom siv zoo rau ib puag ncig rau cov cib magnesia chrome. Tsis muaj kuab paug chromium, cov cib no muaj lub zog kub zoo heev thiab tiv taus alkaline slag zoo dua. Cov khoom siv calcium oxide tuaj yeem nqus cov sulfur thiab cov khoom tsis huv hauv cov hlau molten, ua rau cov hlau stainless zoo dua. Feem ntau cov chaw tsim khoom siv cov cib no rau hauv qab AOD cub tawg, cov ntaub thaiv tas mus li thiab cov ntu phab ntsa pem hauv ntej, ua kom zoo rau kev ua haujlwm ntev ntawm cov hlau.

Cov cib magnesia refractory uas muaj cov xim ntshiab siab yog tsim los rau cov chaw uas tsis muaj xeb thiab qhov kub thiab txias ruaj khov ntawm AOD furnaces. Nrog cov khoom tsis huv uas tsis muaj ntau thiab cov qauv me me, lawv muab lub zog zoo heev thiab tiv taus qhov kub thiab txias siab. Cov cib refractory no pheej yig feem ntau siv rau cov ntaub sab saud ntawm lub cub tawg thiab cov txheej txheem pabcuam, muab kev tiv thaiv ruaj khov thiab txo qis kev nqis peev ntawm cov khoom siv refractory.
