Alumina Lining Plate: Cov Ntawv Thov Tseem Ceeb rau Kev Tiv Thaiv Kev Lag Luam & Kev Ua Haujlwm Zoo

Hauv kev tsim khoom lag luam, kev puas tsuaj, kub siab, thiab kev xeb ntawm cov tshuaj feem ntau ua rau lub neej ntawm cov khoom siv luv luv thiab ua rau tsis ua haujlwm zoo.alumina daim hlau phaj—ua los ntawm Al₂O₃ uas muaj kev ntshiab siab thiab sintered ntawm ntau tshaj 1700 ° C—daws cov teeb meem no. Nrog Rockwell hardness ntawm 80-90 HRA thiab hnav tsis kam 266 npaug ntawm manganese hlau, nws tau dhau los ua ib qho tseem ceeb thoob plaws hauv kev lag luam tseem ceeb. Hauv qab no yog nws cov ntawv thov tseem ceeb thiab vim li cas nws yog kev nqis peev zoo rau cov lag luam uas tsom mus rau kev txiav cov nqi thiab txhawb kev ruaj khov.

1. Cov Ntawv Thov Kev Lag Luam Tseem Ceeb

Cov phaj alumina sab hauv zoo heev nyob rau hauv qhov chaw nyuaj, ua rau lawv tsis tseem ceeb hauv cov chaw uas cov khoom siv raug kev sib txhuam tas li, kev cuam tshuam, lossis kub heev. Nov yog lawv cov kev siv zoo tshaj plaws:

Kev Lag Luam Fais Fab Thermal & Thermal

Cov tshuab xa thee, cov tshuab ua hmoov, thiab cov kav dej tshauv ya hauv cov chaw tsim hluav taws xob thermal thiab cov chaw tsuas zeb ntsib kev puas tsuaj loj heev los ntawm cov khoom me me ntawm thee. Cov hlau ib txwm hnav tawm hauv ntau lub hlis, ua rau lub sijhawm tsis ua haujlwm kim heev. Cov hlau alumina ntev lub neej ntawm cov khoom siv txog li 10 npaug, ua rau lawv ua haujlwm tau ntau xyoo. Lawv qhov kev tiv taus kub siab 1700°C kuj haum rau cov tshuab boiler thiab cov kav dej tso tshauv.

Cov Chaw Ua Hlau, Cement & Mining

Hauv kev tsim cov hlau, cov ntaub thaiv alumina tiv thaiv cov qhov cub tawg, cov tais diav, thiab cov qhov ncauj ntawm lub tshuab hloov pauv los ntawm kev yaig ntawm cov hlau yaj thiab cov slag, ua rau lub neej ua haujlwm ntev dua 50%+. Rau cov chaw tsim cement thiab cov chaw tsuas zeb, lawv ua kab rau cov chutes, cov crushers, thiab cov chaw sib tsoo, tiv thaiv kev cuam tshuam ntawm cov hlau thiab clinker. Cov kav dej tsuas zeb uas muaj alumina ua kab txo qhov hnav ntau heev, tiv thaiv kev xau thiab ua kom cov khoom siv ntau ntxiv.

Kev Lag Luam Tshuaj thiab Iav

Cov chaw tsim tshuaj lom neeg vam khom cov alumina liners rau cov twj tso kua mis, cov hlab dej tshuaj, thiab cov kav dej uas tuav cov kua qaub corrosive, cov hauv paus, thiab cov slurries. Lawv tiv taus cov kua qaub sulfuric concentrated thiab lwm yam xov xwm hnyav, zam kev xau thiab cov khoom ua qias tuaj. Hauv kev tsim iav, lawv qhov kev tiv thaiv kub 1600 ° C ua rau lawv zoo tagnrho rau cov ntaub thaiv cua sov, khaws cov khoom siv thiab xyuas kom meej tias cov iav zoo sib xws.

Kev Siv Tshwj Xeeb

Dhau ntawm cov lag luam tseem ceeb, cov phaj alumina uas muaj cov khoom huv siab (99% Al₂O₃) siv rau hauv cov tsho tiv thaiv tub rog (Kev tiv thaiv theem 3-6) thiab cov tsheb thauj khoom uas muaj hlau tiv thaiv - lawv cov qauv tsim uas tsis hnyav ua rau muaj kev nplij siab yam tsis muaj kev phom sij. Hauv cov chaw tsim khoom, lawv ua cov kab chutes thiab crucibles, tiv taus cov hlau molten thiab cov txheej txheem casting ruaj khov.
