Lub hauv ob sab phlu ntawm lub molten hlau ladle yog ua los ntawm refractory cib los yog refractory mortar, thiab kev xaiv nyob ntawm seb lub cub tawg khiav.
Lub refractory bricks los yog refractory mortar siv rau hauv ob sab phlu ntawm molten hlau ladle txhua tus muaj lawv tus yam ntxwv. Refractory bricks yog yooj yim los tsim, thaum refractory mortar muaj zoo airtightness, stability, thiab tsis muaj hlau to, tab sis nws yog teeb meem los kho.
Yog hais tias lub molten hlau ladle yog ua los ntawm refractory bricks, nws nyob ntawm qhov loj ntawm lub ladle thiab seb nws yog rau desulfurization. Rau qhov zoo tib yam molten hlau ladles nrog me me tonnage, av nplaum cib siv tau rau kev tsim kho, thiab tus naj npawb ntawm lub cub tawg yog nyob ib ncig ntawm 300.
Yog hais tias lub molten hlau ladle yog qhov nruab nrab - hom zoo tib yam, siab - alumina cib tuaj yeem siv rau hauv ob sab phlu. Lub neej kev pab cuam thiab lub cub tawg khiav ntawm lub siab - alumina cib hauv ob sab phlu yog nyob ntawm cov dej muaj pes tsawg leeg ntawm cov hlau thiab cov khoom siv hluav taws xob txhua hnub. Raws li ib txwm muaj, lub neej kev pab cuam yog nyob nruab nrab ntawm 500 thiab 800 rauv khiav.
Yog hais tias nws yog desulfurization thiab refining molten hlau ladle, vim hais tias yuav tsum tau oxygen tshuab thiab chaw nres tsheb, aluminium -carbide- silicon carbon bricks tuaj yeem xaiv rau hauv ob sab phlu refractory. Hom refractory cib no haum rau kev tsim kho. Txawm li cas los xij, tus nqi yog siab, thiab txoj kev sib txuas ntawm lub qhov cub hauv qab thiab lub cub tawg phab ntsa cib tsis zoo ib yam. Lub cib hauv qab ntawm lub ladle yog kim, thiab lub neej kev pab cuam ntawm txhuas -carbide- silicon carbon bricks yog nyob nruab nrab ntawm 800 thiab 1500 rauv khiav.
Rau loj molten hlau ladles, refractory mortar kuj siv tau. Rau hauv ob sab phlu nrog refractory mortar, aluminium -carbide- silicon mortar raug xaiv. Txawm li cas los xij, thaum siv cov tshuaj khib nyiab rau hauv ob sab phlu, yuav tsum muaj pwm thiab lub thawv ci. Yog tsis muaj pwm, kev tsim kho tsis tuaj yeem ua tiav. Nws yog qhov zoo tshaj los ua ib txheej ua haujlwm ntawm 200mm tuab. Yog xav tau ib txheej rwb thaiv tsev, yuav tsum muaj pwm sib txawv. Raws li kev lag luam siv tam sim no, tsuas yog siv cov txheej txheem ua haujlwm. Vim tias muaj ntau ntau hom pwm, nws muaj teeb meem thiab tag nrho kev ncaj ncees tsis muaj zog. Siv aluminium-carbide- silicon mortar rau tag nrho cov pouring ua rau lub airtightness muaj zog, thiab lub neej kev pab cuam nyob nruab nrab ntawm 800 thiab 1200 rauv khiav. Lub sij hawm yog kwv yees li 3 mus rau 6 lub hlis. Qhov tsis zoo yog qhov kev saib xyuas yog qhov teeb meem, thiab nws tsis yooj yim npaum li lub tsev nrog refractory cib.
Hauv cov ntsiab lus, txawm tias siv cov cib refractory los yog cov tshuaj khib nyiab refractory, nws nyob ntawm seb cov khoom puas muaj pwm. Yog tias muaj pwm, aluminium -carbide- silicon refractory mortar tuaj yeem siv rau hauv ob sab phlu. Yog tsis yog, refractory bricks tuaj yeem siv rau hauv ob sab phlu.
