Corundum Cib

Alumina cib feem ntau xa mus rau Alumina silicate cib, nrog Al2O3 thiab SiO2 cov ntsiab lus raws li cov ntsiab lus tseem ceeb, thiab Fe2O3, Na2O, K2O, TiO2 ua impurities.

Nrog cov ntsiab lus Al2O3 sib txawv, alumina cib suav nrog cov av nplaum hluav taws (Al2O3 cov ntsiab lus hauv 48% nrog Kaolin li raw khoom), siab alumina cib (Al2O3 cov ntsiab lus 48% -85%, nrog bauxite li raw khoom), ntom mullite cib, silimanite cib,corundum cib(Al2O3 cov ntsiab lus ntau dua 90% nrog corundum ua raw khoom) thiab lwm yam.

Technical data of alumina bricks generally include chemical composition(content of Al2O3 and Fe2O3), bulk density, apparent porosity, cold crushing strength, permanent liner change and refractoriness under load 0.2 MPa.

Nrog siab dua Al2O3 cov ntsiab lus, cib nrog

Tsawg impurities

zoo dua thermal kuj

Siab crushing zog

Zoo dua corrosion kuj

Kev hloov pauv tsis tu ncua tsawg dua

Kev ua haujlwm ruaj khov dua

Tab sis thermal shock kuj ntawmcorumdum cibtsis muaj zog tshaj li siab alumina cib thiab mullite cib, yog li cov cib uas muaj Al2O3 ntau dua cov ntsiab lus feem ntau yog siv ua hauj lwm hauv ob sab phlu, kilns thiab boiler nrog kub ruaj khov.

Kev tsim cov txheej txheem: Sib tsoo ntawm cov khoom siv raw --- Batching-- Shaping nrog hydraulic xovxwm-- firing hauv qhov kilns --- tshuaj xyuas thiab ntim hauv warehouse

Corundum & Corundum Mullite Cib

Corundum & Corundum Mullite Bricks yog siab alumina refractory bricks rau daim ntawv thov nyob rau hauv huab mob. Cov ntsiab lus alumina feem ntau yog ua tiav los ntawm kev siv cov khoom siv ntshiab ntawm corundum, xws li dawb corundum thiab tabular alumina. Cov av nplaum tshwj xeeb refractory, cov av nplaum tshwj xeeb thiab cov ntshiab silicilic acid hloov kho cov yam ntxwv ntawm daim ntawv cog lus.
Los ntawm cov khoom- tshwj xeeb thiab hom- tshwj xeeb kub kub tua, corundum cib muaj qhov kub thiab txias -tiv taus mullite daim ntawv cog lus, mullite- corundum daim ntawv cog lus lossis daim ntawv cog lus ntshiab corundum.
Daim ntawv thov kub ncav cuag 1700℃rau mullite daim ntawv cog lus thiab mus txog 1800℃rau corundum bond bricks, xws li AL-95. Qhov ntau ntawm cov ntawv thov ntawm cov cib npog yuav luag txhua qhov kev lag luam uas siv cov txheej txheem kub thiab ua kom muaj zog tiv thaiv cov slags thiab cua, nrog rau kev kub siab txaus thiab zoo thermal shock kuj yuav tsum tau.

Silimanite thiab Andalusite Bricks

Tsis muaj kab mob andalusite los ntawm ntuj tsim cov khoom siv raw rau cov cib no. Shaping yuav siv qhov chaw los ntawm hydraulic siab presses los ntawm vibration casting los yog plam casting. Cov qib Andalusite nrog cov cwj pwm zoo ntawm kev ua haujlwm siab, tshwj xeeb tshaj yog qhov kub thiab txias, thiab kev ua haujlwm zoo thermal poob siab tau ua tiav los ntawm kev tsim cov ntawv cog lus tshwj xeeb thiab tau txiav txim siab thiab ua kom zoo dua.
Kub- qhov cub tawg (cowper thiab burner blocks) yog qhov nyiam tshaj plaws ntawm daim ntawv thov rau cov qis- hlau cib, nrog rau cov khoom tshwj xeeb uas muaj cov thermodynamic thiab corrosion resistant zoo heev rau cov iav melters, thiab rau cov cheeb tsam uas kub nruab nrab hauv thermal re-generators, fore-hearth npog thiab feeder expendables.
Cov cib tshwj xeeb nrog cov tshuaj sib txuas tshwj xeeb tau tsim thiab ua pov thawj lawv tus kheej nyob rau hauv daim ntawv thov ntawm cov thermal thiab mechanical kev nyuaj siab, xws li nyob rau hauv cov khib nyiab incinerators thiab combustion chamber.

Mullite Cib

Mullite bricks, raws li hluavtaws fused mullite thiab sintered mullite, yog tsim los ntawm kev xaiv shaping txheej txheem thiab raug rho tawm haujlwm nyob rau hauv qhov cub kub. Mullite cib yog qhov zoo rau kev siv thermal siab, xws li qhov kawg ntawm qhov kub ntawm cov iav melters, nyob rau hauv lub superstructure ntawm lub cub tawg, thiab tshwj xeeb tshaj yog nyob rau hauv lub arch ntawm iav fiber ntau melters, vim lawv zoo heev thermal zog thiab txaus corrosion kuj.
