Ironmaking Blast Furnaces thiab Kub-blast Furnaces

Taw qhia rau tus thawj rwb thaiv tsev qauv ntawm blast furnaces thiab kub-blast furnaces:

Lub tshuab hluav taws xob tawg yog ib hom khoom siv thermal nrog cov qauv nyuaj. Nws yog cov cuab yeej tseem ceeb rau kev ua hlau thiab muaj qhov zoo ntawm cov khoom siv loj, kev tsim khoom siab, thiab cov nqi qis.
Txij li thaum ua haujlwm kub ntawm txhua qhov ntawm lub qhov cub tawg yog qhov siab heev, thiab txhua qhov raug cuam tshuam rau cov khoom siv, xws li kev sib txhuam thiab kev cuam tshuam ntawm cov nqi poob, feem ntau ntawm cov kub-dog refractories siv CCEFIRE kub lub teeb ci ci uas tuaj nrog kub softening kub nyob rau hauv load thiab zoo high-temperature mechanical zog.
Raws li ib qho ntawm cov cuab yeej tseem ceeb ntawm lub tshuab hluav taws xob tawg, lub tshuab hluav taws xob kub kub muab cov cua kub kub kub rau lub tshuab hluav taws xob tawg los ntawm kev siv cov cua sov los ntawm lub tshuab hluav taws xob hluav taws xob hluav taws xob thiab cov hluav taws xob hloov hluav taws xob ntawm cov cib lattice. Txij li txhua feem bears cov kev kub ntxhov siab ntawm cov roj combustion, kev yaig ntawm cov plua plav coj los ntawm cov roj, thiab cov roj combustion, cov kub saum npoo refractories feem ntau xaiv CCEFIRE lub teeb rwb thaiv tsev cib, cov pob zeb kub-resistant, av nplaum cib, thiab lwm yam ntaub ntawv uas muaj zog txhua yam.
Txhawm rau kom ua tiav cov txiaj ntsig thermal rwb thaiv tsev ntawm lub qhov cub hauv ob sab phlu, ua raws li cov hauv paus ntsiab lus ntawm kev xaiv technically txhim khu kev qha, kev lag luam thiab tsim nyog cov ntaub ntawv, lub hauv ob sab phlu ua hauj lwm kub ntawm lub qhov cub tawg thiab nws cov kub moj tej tawg rauv feem ntau xaiv cov ntaub ntawv rwb thaiv tsev uas tsis muaj thermal conductivity thiab zoo rwb thaiv tsev ua yeeb yam.
Cov txheej txheem ntau dua yog xaiv cov khoom siv calcium silicate board, uas muaj cov txheej txheem thermal rwb thaiv tsev tshwj xeeb: lub teeb ci aluminium siab + silica-calcium boards qauv nrog thermal rwb thaiv tsev thickness txog 1000mm.

Cov txheej txheem thermal rwb thaiv tsev no muaj cov teeb meem hauv qab no hauv daim ntawv thov:

A. Cov ntaub ntawv thermal rwb thaiv tsev muaj cov thermal conductivity loj thiab cov thermal rwb thaiv tsev tsis zoo.
B. Cov silicon-calcium boards siv rau hauv cov txheej txheem rov qab tuaj yeem tawg tau yooj yim, tsim qhov tom qab tawg, thiab ua rau kub poob.
C. Loj loj thaum tshav kub kub cia poob, ua rau lub zog pov tseg.
D. Cov calcium silicate boards muaj zog nqus dej, yooj yim tawg, thiab ua haujlwm tsis zoo hauv kev tsim kho.
E. Daim ntawv thov kub ntawm calcium silicate boards yog tsawg ntawm 600 ℃
Cov ntaub ntawv thermal rwb thaiv tsev siv nyob rau hauv lub qhov cub tawg thiab nws lub qhov cub kub kub yuav tsum muaj cov thermal rwb thaiv tsev zoo. Txawm hais tias cov thermal conductivity ntawm calcium silicate boards yog qis dua li ntawm refractory cib thiab thermal rwb thaiv tsev kev ua tau zoo, vim lub cub tawg loj lub cev qhov siab thiab loj cub tawg diameters, calcium silicate boards tawg yooj yim heev thaum lub sij hawm tsim kho vim lawv brittleness, ua rau tsis tiav rov qab hauv ob sab phlu rwb thaiv tsev thiab tsis zoo rwb thaiv tsev. Yog li ntawd, txhawm rau txhawm rau txhim kho cov thermal rwb thaiv tsev los ntawm metallurgical blast furnaces thiab kub blast furnaces, CCEWOOL ceramic fiber ntau cov khoom (cib / boards) tau dhau los ua cov khoom siv zoo tshaj plaws rau kev rwb thaiv tsev rau lawv.

Kev soj ntsuam ntawm ceramic fiberboards 'kev ua yeeb yam:

CCEWOOL ceramic fiberboards txais cov khoom zoo AL2O3 + SiO2 = 97-99% fibers ua raw cov ntaub ntawv, ua ke nrog inorganic binders ua lub ntsiab lub cev thiab high-temperature fillers thiab additives. Lawv yog tsim los ntawm stirring thiab pulping thiab lub tshuab nqus tsev nqus pom. Tom qab cov khoom qhuav qhuav, lawv tau ua tiav los ntawm cov khoom siv machining los ua kom tiav cov txheej txheem ua tiav, xws li txiav, sib tsoo, thiab drilling kom ntseeg tau tias cov khoom ua tau zoo thiab qhov tseeb qhov tseeb yog nyob rau theem thoob ntiaj teb. Lawv lub ntsiab technical nta muaj xws li:
ib. Cov tshuaj purity siab: muaj 97-99% high-temperature oxides xws li Al2O3 thiab SiO2, uas ua kom lub tshav kub tsis kam ntawm cov khoom. CCEWOOL ceramic fiberboards tuaj yeem tsis tsuas yog hloov cov calcium silicate boards ua rau cov phab ntsa hauv lub qhov cub, tab sis kuj tseem siv ncaj qha rau ntawm qhov kub ntawm cov phab ntsa ntawm lub qhov cub kom muab lawv nrog cov cua yaig zoo heev.
b. Tsawg thermal conductivity thiab thermal rwb thaiv tsev zoo: Vim tias cov khoom no yog CCEWOOL ceramic fiber ntau cov khoom tsim los ntawm cov txheej txheem txuas ntxiv tshwj xeeb, nws muaj kev ua tau zoo dua li cov tsoos diatomaceous earth bricks, calcium silicate boards thiab lwm yam khoom siv silicate backing cov ntaub ntawv hauv nws cov thermal conductivity tsawg, kev txuag hluav taws xob zoo dua, thiab tseem ceeb txuag hluav taws xob.
c. Lub zog siab thiab siv tau yooj yim: Cov khoom lag luam muaj lub zog compressive thiab flexural zog thiab yog cov ntaub ntawv uas tsis yog nkig, yog li lawv ua tau raws li qhov yuav tsum tau ua ntawm cov ntaub ntawv tawv rov qab. Lawv tuaj yeem siv tau rau hauv cov phiaj xwm rwb thaiv tsev uas xav tau lub zog siab, hloov cov ntaub ntawv rov qab ntawm cov pam vov lossis cov ntaub. Lub caij no, cov txheej txheem CCEWOOL ceramic fiberboards muaj qhov tseeb geometric qhov ntev thiab tuaj yeem txiav thiab ua tiav ntawm qhov xav tau. Kev tsim kho yog yooj yim heev, uas daws cov teeb meem ntawm brittleness, fragility thiab siab kev tsim kho tus nqi ntawm calcium silicate boards. Lawv ua kom luv luv lub sijhawm tsim kho thiab txo cov nqi tsim kho.
Hauv cov ntsiab lus, CCEWOOL ceramic fiberboards tsim los ntawm lub tshuab nqus tsev tsis yog tsuas yog muaj cov khoom siv zoo heev thiab cov duab geometric qhov ntev, tab sis kuj tswj cov yam ntxwv zoo ntawm fiber ntau cov ntaub ntawv rwb thaiv tsev kub. Lawv tuaj yeem hloov cov calcium silicate boards thiab siv rau thaj chaw rwb thaiv tsev uas yuav tsum tau muaj zog thiab kev txhawb nqa tus kheej thiab hluav taws kub.
