Cov Hlau Tee Uas Muaj Alumina Ceramic Uas Tiv Thaiv Tau Zoo Heev: Cov Khoom Tseem Ceeb thiab Cov Kev Siv Hauv Kev Lag Luam

Lub txheej ua haujlwm tseem ceeb ntawm cov hlau tee uas muaj alumina ceramic uas tiv taus hnav yog cov ntaub ceramic ua los ntawm alumina uas muaj purity siab (α-Al₂O₃). Cov khoom siv no muaj cov qauv siv lead ua corundum ruaj khov, nrog rau qhov nyuaj txog HRA 85 lossis siab dua (Vickers hardness HV 1000-1600) thiab qhov ceev ntawm 3.6-3.9 g/cm³. Lub luag haujlwm tseem ceeb ntawm cov ntaub ceramic alumina yog tiv taus qhov kev puas tsuaj ntawm cov khoom khov kho ntawm cov kav dej. Nws qhov kev tiv thaiv kev hnav tau raug kuaj hauv chaw kuaj mob kom yog 266 npaug ntawm cov hlau manganese thiab 171.5 npaug ntawm cov hlau cam khwb cia siab chromium. Cov ntaub ntawv siv hauv kev lag luam qhia tau tias cov ntaub no tuaj yeem ntev lub neej ntawm cov kav dej ntau dua kaum npaug. Ntxiv mus, alumina ruaj khov thiab tsis muaj tshuaj lom neeg, muab kev tiv thaiv rau cov kua qaub, alkalis, ntsev, thiab cov xov xwm organic hauv qhov kub thiab txias tshwj xeeb.

Cov hlau tees uas muaj alumina ceramic uas tiv taus hnav tau siv rau ntau yam kev lag luam uas hnav hnyav. Hauv cov tshuab hluav taws xob thermal, lawv siv rau hauv cov kav dej xa hmoov thee, cov tshuab pulverizing, cov kav dej tshem tshauv, thiab cov tshuab tshem plua plav. Hauv kev lag luam mining, lawv tsim nyog rau kev thauj slurry, kev thauj tailings, kev thauj concentrate, thiab cov kav dej thauj thee huv hauv cov nroj tsuag npaj thee nruab nrab hnyav. Hauv cov hlau thiab hlau metallurgy teb, lawv siv rau hauv cov tshuab tshem plua plav cua sov, cov kab thauj slag, thiab kev thauj khoom thaum lub sijhawm smelting. Hauv kev lag luam cement, lawv siv rau hauv cov tshuab thauj pneumatic rau cov hmoov nplej nyoos, clinker, thiab cov tshauv ya. Hauv kev lag luam tshuaj lom neeg, lawv tsim nyog rau cov kav dej xa cov khoom corrosive thiab abrasive. Ntawm cov chaw nres nkoj, lawv siv rau kev thauj slurry thiab sediment. Tsis tas li ntawd, cov khoom no tuaj yeem siv rau cov ntawv thov tshwj xeeb xws li kev thauj txhuas molten.

Thaum lub sijhawm xaiv, yuav tsum xav txog tej yam xws li cov yam ntxwv nruab nrab, qhov loj ntawm cov khoom me me, qhov kub ntawm kev xa khoom, thiab lub kaum sab xis ntawm qhov cuam tshuam kom txiav txim siab qhov tuab ntawm cov txheej ceramic (feem ntau yog 4-20 hli), qhov huv ntawm alumina, thiab txoj kev sib txuas ntawm cov yeeb nkab sab nraud (flanged, welded, thiab lwm yam). Txawm hais tias qhov kev nqis peev thawj zaug rau qhov kev sib txuas no siab dua li cov yeeb nkab hlau txheem, nws lub neej ua haujlwm ntev dua thiab kev txo qis ntawm lub sijhawm tsis ua haujlwm thiab cov nqi txij nkawm ua rau nws yog qhov kev daws teeb meem zoo rau kev hnav thiab xeb hnyav.
