1. zawv zawg rooj vag teeb
Zoo thermal shock stability thiab hnav tsis kam yog thawj qhov kev xaiv yuav tsum tau rau cov ntaub ntawv refractory rau zawv zawg nozzles. Thiab sintered tabular alumina tsuas yog tuaj yeem ua tau raws li nws cov cai. Tam sim no, ntxiv qhov tsim nyog ntawm graphite (los yog carbon dub) thiab antioxidant rau sintered tabular alumina yog cov khoom siv ntawm aluminium-carbon zawv zawg nozzle, los yog ntxiv cov nyiaj tsim nyog ntawm zirconia, graphite (los yog carbon dub) thiab antioxidant rau sintered tabular alumina. aluminium-zirconium-carbon zawv zawg nozzle raws li cov khoom siv tseem ceeb tseem yog lub cev tseem ceeb ntawm cov khoom siv zawv zawg nozzle.
2. Ladle castable
Nrog rau kev txhim kho txuas ntxiv ntawm kev siv thev naus laus zis sab nraud ntawm lub qhov cub, kev ua haujlwm ntawm cov khoom siv refractory hauv ladles tau dhau los ua hnyav dua. Molten steel yuav tsum nyob twj ywm rau hauv lub ladle rau lub sij hawm ntev rau stirring, cua sov, thiab yaig ntawm txawv steel slags. Ib qho khoom siv xws li magnesium lossis aluminium rau ladle hauv ob sab phlu tau hloov los ntawm cov ntaub ntawv sib xyaw. Aluminium-magnesium-spinel system castable nrog sintered tabular alumina thiab spinel raws li cov ntaub ntawv tseem ceeb yog siv rau hauv qab lossis phab ntsa cladding, thiab cov magnesia carbon cib siv rau cov kab slag, uas yog hom yooj yim rau kev siv. loj thiab nruab nrab ladle refractories tam sim no.
3. Prefab refractory
Purging plugs, lub rooj bricks, tshuaj tsuag phom, cuam tshuam daim hlau, thiab lwm yam tsis yog tsuas yog ib feem ntawm lub ladle refractory hauv ob sab phlu, tab sis kuj plays ib tug tseem ceeb luag hauj lwm nyob rau hauv lub steelmaking txheej txheem nws tus kheej. Kev siv ua ke ntawm sintered tabular alumina, spinel thiab lwm yam khoom siv raw khoom tuaj yeem txhim kho cov khoom siv thermodynamic ntawm cov ntaub ntawv refractory, uas yog, txhim kho hnav tsis kam thiab yaig kuj.
