CCEFIRE® DEHA Series High alumina refractory cib yog ib yam khoom nruab nrab refractory nrog txhuas cov ntsiab lus ntau dua 48%. High alumina refractory cib yog tsim los ntawm calcination thiab molding los ntawm bauxite thiab lwm yam ntaub ntawv raw nrog cov ntsiab lus siab ntawm alumina. Raws li cov ntsiab lus sib txawv ntawm alumina nyob rau hauv siab alumina cib, nws cov hluav taws kub tsis kam, refractoriness nyob rau hauv load, compressive zog thiab lwm yam qhia tau txawv.
Cov khoom ruaj khov zoo
Kev tswj nruj ntawm cov khoom siv raw
Tswj cov ntsiab lus impurity, xyuas kom tsis muaj thermal shrinkage, thiab txhim kho cov cua sov
1. Muaj lub hauv paus loj ore, cov cuab yeej siv mining, thiab kev xaiv cov khoom siv nruj dua.
2. Cov khoom siv raw tuaj yeem raug kuaj ua ntej, thiab tom qab ntawd cov ntaub ntawv raw khoom tsim nyog tau muab khaws cia rau hauv ib lub tsev khaws khoom raw khoom los xyuas kom meej tias lawv purity.
3. Cov khoom siv raw ntawm CCEFIRE High alumina bricks muaj cov ntsiab lus impurity tsawg dua 1% oxides, xws li hlau thiab alkali hlau. Yog li ntawd, CCEFIRE High alumina bricks muaj siab refractoriness.
Kev tswj cov txheej txheem ntau lawm
Txo cov ntsiab lus ntawm cov pob slag, xyuas kom tsis muaj thermal conductivity, thiab txhim kho thermal rwb thaiv tsev kev ua tau zoo
1. Lub siab automated batching system tag nrho lav qhov ruaj khov ntawm cov khoom siv raw khoom thiab qhov tseeb zoo dua hauv cov khoom siv raw.
2. Nrog thoob ntiaj teb advanced automated ntau lawm kab ntawm high-temp tunnel furnaces, shuttle furnaces, thiab rotary furnaces, cov txheej txheem ntau lawm los ntawm raw cov ntaub ntawv mus rau cov khoom tiav yog nyob rau hauv tsis siv neeg computer-tswj, kom ruaj khov khoom zoo.
3. Automated furnaces, ruaj khov kub tswj, tsis tshua muaj thermal conductivity ntawm CCEFIRE High alumina bricks, zoo heev thermal rwb thaiv tsev kev ua tau zoo, tsawg tshaj li 0.5% nyob rau hauv cov kab hloov mus tas li, ruaj khov zoo, thiab ntev kev pab cuam lub neej.
4. Ntau yam duab ntawm siab alumina cib tuaj yeem ua raws li kev tsim qauv. Lawv muaj qhov loj me me nrog qhov yuam kev ntawm +1mm thiab yooj yim rau cov neeg siv khoom nruab.
Kev tswj kom zoo
Xyuas kom meej bulk ntom thiab txhim kho cov thermal rwb thaiv tsev ua haujlwm
1. Txhua qhov khoom xa tuaj muaj tus kws tshuaj xyuas zoo, thiab daim ntawv tshaj tawm kev xeem tau muab ua ntej kev tawm ntawm cov khoom los ntawm lub Hoobkas los xyuas kom meej cov khoom xa tawm ntawm txhua qhov kev xa khoom ntawm CCEFIRE.
2. Kev tshuaj xyuas thib peb (xws li SGS, BV, thiab lwm yam) tau txais.
3. Ntau lawm yog nruj me ntsis raws li ASTM zoo tswj system ntawv pov thawj.
4. Lub ntim sab nrauv ntawm txhua lub thawv yog ua los ntawm tsib txheej ntawm kraft ntawv, thiab cov ntim khoom sab nrauv + pallet,, tsim nyog rau kev thauj mus los ntev.
Cov yam ntxwv zoo
1. Refractoriness
Lub refractoriness ntawm CCEFIRE siab alumina cib yog siab dua li cov av nplaum refractory cib thiab semi-silica cib, ncav cuag 1750 ~ 1790 ℃, uas yog ib yam ntawm high-qib refractory ntaub ntawv.
2. Load softening kub
Txij li cov khoom siv alumina siab muaj Al2O3 siab, tsis muaj impurities tsawg, thiab cov iav fusible tsawg, cov khoom muag muag kub yog siab dua li cov av nplaum cib, tab sis vim tias mullite crystals tsis tsim ib lub network qauv, qhov load softening kub tseem tsis siab li silica cib.
3. Slag tsis kam
CCEFIRE high-alumina cib muaj ntau dua Al2O3, ze rau cov khoom nruab nrab refractory, yog li lawv tuaj yeem tiv taus cov kua qaub slag thiab alkaline slag. Vim yog cov ntsiab lus ntawm SiO2, qhov kev tiv thaiv rau alkaline slag tsis muaj zog dua li cov kua qaub slag.
High alumina bricks characterized nrog siab thermal stability, siab refractoriness saum 1770 degrees, zoo slag kuj, feem ntau yog siv rau hluav taws xob rauv saum toj, ncej rauv, kub moj tej tawg rauv, ladle, molten hlau, cement kiln, iav kiln thiab lwm thermal furnace hauv ob sab phlu. Siv dav hauv kev tsim hlau, hlau ua, tshuaj lom neeg kev lag luam, cement thiab lwm yam lag luam.
