Khoom Description
Refractory dag corundum tabular alumina yog tsim los ntawm homogenizing siab -purity alumina hmoov raw cov ntaub ntawv thiab shaping lawv mus rau hauv ntsuab lub cev los ntawm qhuav nias los yog isostatic nias los xyuas kom meej qhov ntom ntom. Ceev ceev siab -kub sintering ntawm 1900 ° C mus rau 2000 ° C nyob rau hauv lub qhov cub. Thaum lub sij hawm tus txheej txheem no, tsis muaj sintering pab ntxiv kom tsis txhob qhia impurities thiab tuav lub inherent kub kub tsis kam ntawm cov khoom. Kev nrawm nrawm txhawb kev loj hlob ntawm qhov loj thiab zoo-tsim hexagonal phaj- zoo li cov muaju, thaum kaw lub qhov pores yog tsim nyob rau hauv cov muaju thaum lub sij hawm recrystallization. Thaum kawg, cov sintered blocks undergo crushing, tshuaj ntsuam, thiab grading kom tau standardized particle qhov ntau thiab tsawg, kom ntseeg tau zoo ib yam ntawm txhua batch ntawm cov khoom.
Taw qhia
Tabular Alumina yog ib qho ntshiab sintered alpha-alumina cov ntaub ntawv uas tau tag nrho densified los ntawm ceev ceev -sintering yam tsis tau siv cov sintering pab ntawm kub tshaj 1900 degree.
Tabular Alumina muaj cov yam ntxwv loj, zoo tsim hexagonal ntsiav tshuaj zoo li alpha{0}}alumina crystals. Qhov zoo tshaj plaws thermal ntim ruaj khov thiab thermal shock yam ntxwv tuaj yeem raug ntaus nqi rau nws qhov tshwj xeeb microstructure: qis qhib porosity thiab cov muaju loj nrog kaw lub qhov pores, uas yog entrapped rau re-crystallization thaum lub sij hawm sintering ceev.
Qhov zoo
1. Zoo heev kub stability thiab thermal shock kuj
Lub melting point ntawm refractory dag corundum phaj-zoo li alumina yog 2040℃C, thiab nws tswj lub cev ruaj khov ntawm qhov kub txog li 1600℃C. Nws cov phaj tshwj xeeb-zoo li cov qauv siv lead ua thiab cov porosity tsawg txo qhov ntim qis nyob rau hauv lub sij hawm ntev - kub raug. Tsis zoo li cov khoom siv refractory zoo tib yam uas tawg los yog tev tawm nyob rau hauv qhov kub thiab txias hloov pauv, nws tuaj yeem tiv taus cov cua sov thiab cua txias, txo qis kev poob qis hauv qhov cub.
2. Cov tshuaj tiv thaiv corrosion zoo heev
Cov khoom no muaj ultra-siab purity thiab tsis muaj impurity cov ntsiab lus, thiab muaj peev xwm tiv taus corrosion los ntawm feem ntau slag, acids, thiab alkalis (tshwj tsis yog hydrofluoric acid thiab phosphoric acid). Nws cov qauv siv lead ua ntom ntom tuaj yeem tiv thaiv slag infiltration, uas yog ib qho ua rau tsis ua hauj lwm hauv cov hlua refractory hauv cov hlau thiab cov cement industries. Nyob rau hauv cov cheeb tsam ntawm steelmaking ladles thiab cement kiln burners, nws zoo tiv thaiv kev yaig ntawm molten steel, slag, thiab alkaline gases. Piv nrog rau cov khoom siv alumina refractory zoo tib yam, kev pab cuam lub neej ntawm cov ntaub ntawv refractory txuas ntxiv los ntawm 30-50%.
3. Lub zog txhua yam muaj zog thiab hnav tsis kam
Lub Mohs hardness yog 9, nrog lub siab ntim ntim thiab zoo heev hnav tsis kam thiab cuam tshuam tsis kam. Cov phaj sib txuas-zoo li cov khoom siv lead ua txhim kho lub zog sib txuas ntawm cov khoom sib xyaw refractory, ua kom muaj kev ncaj ncees hauv cov khoom siv hnyav. Txawm hais tias siv los ua cov ntaub ntawv refractory hauv cov chaw hnav siab lossis ua qhov sib tsoo nruab nrab rau cov khoom siv tawv tawv, nws tuaj yeem tswj tau qhov kev ua haujlwm ruaj khov yam tsis muaj kev hnav ntau dhau los yog tawg, yog li txo qhov hloov zaus thiab ntev - cov nqi.
Daim ntawv thov
1. Hlau thiab metallurgical kev lag luam
Hauv steelmaking, nws yog ib qho tseem ceeb raw khoom rau ladle hauv ob sab phlu, intermediate ladle refractory cov ntaub ntawv, thiab zawv zawg qhov rooj panels. Nws tiv taus qhov yaig ntawm cov hlau molten thiab siab -kub slag, uas yog qhov tseem ceeb rau kev tsim cov hlau tsis tu ncua. Nyob rau hauv tsis yog -ferrous metallurgy, nws yog siv los ua ib lub hauv ob sab phlu rau aluminium smelting furnaces, uas tuaj yeem tiv taus corrosive molten aluminium thiab kub kub, ua kom ruaj khov ntawm lub cub tawg.
2. Cement thiab iav kev lag luam
Qhov chaw burner, qhov hluav taws xob hauv ob sab phlu, thiab preheater Cheebtsam ntawm cov cement kiln tag nrho cia siab rau nws, qhov twg refractory dag corundum tabular alumina tuaj yeem tiv taus alkali corrosion thiab thermal cycling. Hauv kev tsim cov iav, nws yog siv los yaj lub tank liners thiab regenerator refractory cov ntaub ntawv, tswj cov iav purity, thiab tiv thaiv corrosion ntawm molten iav ntawm 1500℃C. Nws cov thermal conductivity tsawg kuj txo cov kev siv zog ntawm cov txheej txheem siv zog.
3. Petrochemical thiab pov tseg incineration kev lag luam
Hauv petrochemical reactors thiab siab -kub rauv, nws tiv thaiv corrosion los ntawm acidic thiab alkaline gases ntawm qhov kub thiab txias. Rau cov khib nyiab incinerators, lawv tuaj yeem tiv taus qhov kub thiab txias corrosive fumes, tiv thaiv hauv ob sab phlu puas, thiab xyuas kom muaj kev nyab xeeb thiab txuag cov khib nyiab. Nws tseem tuaj yeem ua haujlwm siab -kev ua haujlwm catalyst cab kuj, siv nws cov qauv ruaj khov thiab kub tsis kam.
4. Advanced ceramic thiab refractory khoom
Raws li cov khoom siv raw rau siab-kawg ceramics, nws tsim cov rooj tog hauv tsev (rollers, crucibles), ceramic crucibles, thiab hluav taws xob insulators, txhim kho thermal shock thiab deformation kuj. Nyob rau hauv tag nrho cov ntaub ntawv refractory, nws yog ntxiv rau cov cement castables tsawg thiab refractory mortar los txhim kho lub zog thiab durability ntawm complex zoo li refractory Cheebtsam.
