Cov khoom siv refractory rau hauv ob sab phlu ntawm qhov cub tawg

Cov khoom siv refractory yog siv rau hauv caj pas, lub cev, plab, thiab lub plawv ntawm lub qhov cub tawg. Lub refractory cib manufacturers tseem yuav qhia rau koj.

Lub tshuab hluav taws xob tawg tsuas yog cov khoom siv hlau ua hlau. Hlau ore, coke, thiab lwm yam yog qhia los ntawm sab saum toj ntawm lub cub tawg nyob rau hauv kev faib ua feem, thiab kub moj tej tawg (1000 ~ 1200 ℃) yog nkag mus rau hauv lub qis tuyere. Cov tshuaj tiv thaiv oxidation-txo yog nqa tawm hauv qhov cub tawg. Hlau slag, slag hlau ntws tawm ntawm lub qhov hlau ntawm qhov qis ntawm qhov cub tawg kom cais cov hlau thiab slag. Lub slag nkag mus rau hauv slag ditch, flushes lub slag los yog nkag mus rau lub qhuav slag qhov. Cov hlau molten nkag mus rau hauv lub tank torpedo los ntawm lub viav vias nozzle los yog txuas ntxiv ua hlau los yog xa mus rau lub tshuab hlau casting. Thaum kawg, cov blast furnace gas yog tawm los ntawm cov khoom siv tshem tawm plua plav. Qhov no yog tag nrho cov txheej txheem ntawm blast furnace ironmaking.

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 ntev, thiab blast furnace hauv ob sab phlu refractories muaj correspondingly xav tau ntau dua. Xws li zoo refractoriness, kub stability, ceev, thermal conductivity, hnav tsis kam, yaig kuj thiab slag kuj.

Tam sim no, muaj ntau ntau yam ntawm cov ntaub ntawv refractory nyob rau hauv blast furnaces, thiab kev siv cov ntaub ntawv refractory nyob rau hauv ntau qhov chaw yog txawv los ntawm cov yam ntxwv ntawm lub cub tawg.

Nyob rau hauv lub cub tawg caj pas, lub refractory masonry yog siv los ua ib qho kev tiv thaiv hauv ob sab phlu rau cov ntaub tsim nyog. Qhov ntsuas kub yog 400 ~ 500 ℃, thiab nws raug cuam tshuam ncaj qha thiab kev sib txhuam los ntawm tus nqi, thiab cov nyhuv ntawm huab cua ntws yog me ntsis sib dua. Ntawm no, tuab av nplaum cib, siab alumina bricks, av nplaum castables / tsuag xim tsev, thiab lwm yam yuav siv tau rau masonry.

Lub tshuab hluav taws xob lub cev yog ib feem tseem ceeb ntawm lub qhov cub tawg, uas yog siv los ua cua sov, txo thiab slagging ntawm tus nqi. Ntawm no, kev yaig ntawm cov ntaub ntawv thiab cov cua kub cua kub yog qhov hnyav dua. Qhov kub hauv nruab nrab ntawm lub cub tawg yog 400 ~ 800 ℃, thiab tsis muaj slag yaig. Nws feem ntau cuam tshuam los ntawm kev yaig ntawm cov plua plav nce, thermal shock, alkali zinc thiab carbon deposition. Yog li ntawd, tuab av nplaum cib thiab siab alumina bricks yog siv rau hauv lub Upper ib feem ntawm qhov, thiab anti-stripping coj-resistant phosphate av nplaum cib, siab alumina bricks, thiab sillimanite bricks yog siv rau cov masonry; Qhov qis ntawm lub tshuab ua kom sov lub cev siv ntom ntom thiab hnav cov av nplaum tiv taus, siab alumina cib, thiab corundum cib. , Carborundum bricks rau masonry.

Lub plab ntawm lub cub tawg ua ib qho tsis rau kev hloov kho, qhov twg ib feem ntawm cov nqi txo qis thiab slagging, thiab lub tshuab hluav taws xob hauv ob sab phlu yog hnyav heev los ntawm cov hlau slag. Qhov kub ntawm no yog siab li 1400 ~ 1600 ℃ nyob rau sab sauv thiab 1600 ~ 1650 ℃ nyob rau hauv qis. Vim tias muaj kev cuam tshuam loj ntawm cov hluav taws xob kub kub, alkali yaig, kub plua plav nce rauv roj, thiab lwm yam, cov ntaub ntawv refractory ntawm lub qhov cub hauv ob sab phlu ntawm no raug puas tsuaj loj. Yog li ntawd, cov ntaub ntawv refractory uas muaj zog tiv thaiv slag yaig thiab yaig thiab puas yuav tsum tau xaiv ntawm no. Lub qhov cub hauv plab tuaj yeem siv cov av nplaum uas tsis muaj porosity, siab alumina cib, graphite cib, silicon carbide cib, corundum cib, thiab lwm yam rau masonry.

Lub hearth yog qhov chaw uas molten hlau thiab molten slag loaded. Qhov kub siab tshaj plaws hauv thaj chaw tuyere yog 1700 ~ 2000 ℃, thiab qhov kub ntawm qhov cub hauv qab yog 1450 ~ 1500 ℃. Ntxiv nrog rau qhov raug cuam tshuam los ntawm qhov kub thiab txias, lub hauv paus hearth kuj eroded los ntawm slag thiab hlau. Lub hearth tuyere tuaj yeem siv corundum mullite cib, xim av corundum cib, thiab sillimanite cib rau masonry. Corundum mullite cib thiab xim av corundum cib yog siv rau qhov kub ntawm qhov sib cuag slag-hlau, thiab cov pa roj carbon ntau thiab graphite semi-graphite cib yog siv rau qhov chaw txias. Carbon bricks, microporous carbon bricks, molded carbon cib, sidewall xim av corundum tsawg cement prefabricated blocks, hearth kub pressed me me carbon bricks, rauv hauv qab siv graphite semi-graphite carbon bricks, microporous carbon bricks, thiab lwm yam rau masonry.

Tsis tas li ntawd, av nplaum cib, silicon carbide cib, graphite cib, fused corundum castables, silicon carbide castables, hlau ditch thermal spray kho cov ntaub ntawv yuav siv tau rau lub moj tej tawg rauv hlau trough. Lub ditch npog siv cov cement tsawg thiab siab aluminium castables thiab skimmer ib feem Siv cov cement corundum castable tsawg, cov khoom siv refractory ntawm lub viav vias nozzle zoo ib yam li cov hlau ditch, thiab slag ditch tuaj yeem ua los ntawm cov khoom siv qis dua.
