Lub tshuab hluav taws xob tawg yog cov khoom siv hlau ua ntau tshaj plaws. Hauv cov ntsiab lus yooj yooj yim, hlau ore, coke, thiab lwm yam yog pub proportionally los ntawm sab saum toj ntawm lub cub tawg mus rau hauv qab tuyere, thiab ces nkag mus rau lub high-kub moj tej tawg ntawm 1, 000 mus rau 1,200 degrees Celsius, thiab oxidized nyob rau hauv. lub qhov cub tawg. Kev txo cov tshuaj tiv thaiv tsim cov hlau slag. Cov hlau slag ntws tawm ntawm qhov qis hlau ntawm lub qhov cub tawg, thiab cais cov hlau slag, cov cuab yeej slag, slag trench, flushing slag los yog nkag mus rau hauv qhov qhuav slag. xa mus rau lub tshuab cam khwb cia hlau. Thaum kawg, cov blast furnace gas yog tawm los ntawm cov khoom siv tshem tawm plua plav, thiab tag nrho cov txheej txheem smelting yog tej zaum zoo li no.
Nrog rau txoj kev loj hlob thiab kev loj hlob ntawm cov hlau thiab hlau kev lag luam nyob rau hauv ntau lub teb chaws, blast furnaces yog maj mam loj hlob mus rau loj-scale, high-efficiency thiab lub neej ntev. Lub blast furnace hauv ob sab phlu refractories muaj c
los yog xav tau ntau dua. Xws li zoo refractoriness, kub stability, ceev, thermal conductivity, hnav tsis kam, yaig kuj thiab compression kuj.
Tam sim no, muaj ntau yam khoom siv refractory rau blast furnaces, thiab cov khoom sib txawv yuav tsum xaiv cov khoom siv refractory tsim nyog raws li cov kev xav tau sib txawv.
Rauv caj pas
Ntawm no, cov roj refractory yog siv los tiv thaiv cov ntaub ntawv tsim nyog. Qhov kub ntawm 400 thiab 500 degrees Celsius. Nws raug cuam tshuam los ntawm kev cuam tshuam ncaj qha thiab kev sib txhuam ntawm tus nqi, thiab huab cua scouring nyhuv yog me ntsis sib dua. Cov av nplaum zoo heev thiab siab alumina cib tuaj yeem siv ntawm no. , av nplaum pouring khoom, tshuaj tsuag xim, thiab lwm yam rau masonry.
Rauv lub cev qhov chaw
Lub tshuab hluav taws xob lub cev yog ib qho tseem ceeb ntawm lub qhov cub tawg, uas yog siv rau kev them nyiaj, txo qis thiab slag troughing. Ntawm no, qhov scouring ntawm cov khoom thiab qhov kub-kub airflow yog hnyav dua. Qhov kub ntawm qhov nruab nrab ntawm lub cub tawg yog nruab nrab ntawm 400 thiab 800 degrees Celsius, thiab tsis muaj kev cuam tshuam ntawm slag yaig. Nws yog feem ntau cuam tshuam los ntawm kev yaig ntawm cov pa roj av nce ntxiv, thermal shock alkalinity thiab kev puas tsuaj los ntawm carbon deposition. Yog li no, av nplaum tuab, High-alumina cib, tiv thaiv cov cib av, thiab cov cib ntau rau cov me me hauv ntu ntawm ntu no. Qhov qis dua ntawm lub tshuab ua kom sov lub cev yog ua los ntawm cov av nplaum hnyav hnyav hnyav, siab alumina cib, corundum cib thiab silicon carbide cib.
Hearth txoj hauj lwm
Lub tshuab hluav taws xob ua lub luag haujlwm buffering rau kev hloov kho tshiab. Ib feem ntawm tus nqi raug txo qis ntawm no los ua cov slag, thiab lub tshuab hluav taws xob hauv ob sab phlu yog eroded los ntawm hlau slag. Ntawm 1650 degrees Celsius, qhov sib xyaw ua ke ntawm cov hluav taws xob kub kub, alkali yaig, kub plua plav-laden nce rauv roj, thiab lwm yam, ua rau muaj kev puas tsuaj loj rau cov ntaub ntawv refractory ntawm lub cub tawg. Yog li ntawd, cov ntaub ntawv refractory uas muaj zog slag yaig kuj thiab yaig kuj yuav tsum tau xaiv ntawm no. Cov av nplaum zoo nrog cov porosity tsawg thiab siab alumina cib, graphite cib, silicon carbide cib, corundum cib, thiab lwm yam.
Hearth qhov chaw
Lub hearth ib feem yog cov kabmob ntawm cov hlau molten thiab molten slag. Qhov kub siab tshaj plaws nyob rau hauv qhov chaw sib khi yog nyob nruab nrab ntawm 1,700 thiab 2, 000 degrees Celsius, thiab qhov kub nyob hauv qab ntawm lub cub tawg yog nyob nruab nrab ntawm 1,450 thiab 1,500 degrees Celsius. Ntxiv rau qhov raug cuam tshuam los ntawm qhov kub thiab txias, lub refractory hauv ob sab phlu ntawm lub hearth kuj raug rau lub cev lub zog los ntawm molten hlau slag thiab cov khoom siv refractory sab sauv vim nws tau immersed nyob rau hauv molten hlau ntev. Kev khawb thiab yaig ntawm molten hlau slag, nrog rau cov nyhuv ntawm molten hlau nyob rau hauv buoyancy ntawm lub cub tawg steel refractories, lub sealing ib feem ntawm lub cub tawg steel yuav ua tau nrog steel jade graphite cib, xim av steel jade cib, thiab sillimanite cib. Lub slag hlau hu rau saum npoo kub, siv steel jade graphite rau pob zeb cib, xim av steel jade cib, thiab tuab carbon cib, graphite semi-graphite carbon bricks, microporous carbon bricks, thiab milled carbon cib rau qhov txias.
Lwm qhov chaw
Av nplaum cib, silicon carbide cib, graphite cib, fused corundum castables, silicon carbide castables, thiab hlau nuv kub-txhaj tshuaj kho cov ntaub ntawv yuav siv tau nyob rau hauv lub tapping ditch ntawm lub blast furnace.
Lub hau npog siv qis-cement high-aluminium castables.
Ib qho qis cement corundum castable yog siv rau skimmer.
Cov khoom siv refractory ntawm lub viav vias nozzle zoo ib yam li cov khoom siv hlau.
Slag ditch tuaj yeem siv cov khoom qis me ntsis.
