Nrog rau kev txhim kho txuas ntxiv ntawm kev tsim khoom lag luam, cov ntaub ntawv refractory tau siv dav. Ntawm lawv, av nplaum high-alumina refractory cib, ua cov khoom tseem ceeb refractory, tau siv dav hauv ntau yam kev lag luam. Txawm li cas los xij, vim muaj qhov sib txawv ntawm kev siv ib puag ncig, peb yuav tsum tau them sai sai rau qee yam thaum siv los xyuas kom meej tias cov khoom lag luam zoo li qub. Kab lus no yuav qhia meej txog kev ceev faj rau kev siv av nplaum siab alumina refractory cib.
Common av nplaum siab alumina refractory cib khoom
Av nplaum high-alumina refractory bricks yog ua los ntawm kaolin thiab high-alumina bauxite ua cov ntaub ntawv tseem ceeb, thiab yog tsim los ntawm crushing, mixing, shaping, firing thiab lwm yam txheej txheem. Nws yog dav siv rau nws cov khoom xws li kub tsis kam, hnav tsis kam thiab tshuaj corrosion kuj. Cov av nplaum siab-alumina refractory cib feem ntau suav nrog cov hom phiaj dav dav refractory cib, crystallized refractory cib, high-alumina insulating cib, ceramic refractory pob, thiab lwm yam.
Kev ceev faj rau kev siv av nplaum siab alumina refractory cib
1. Ua tib zoo saib cov pob qij txha ntawm cov cib thaum txhim kho
Thaum siv cov av nplaum siab alumina refractory cib, xyuam xim rau kev txhim kho cov pob qij txha. Ua ntej kev teeb tsa, qhov ntev ntawm cov cib yuav tsum tau ua tib zoo xyuas kom ntseeg tau tias lawv tsim nyog. Thaum lub sij hawm installation txheej txheem, cib squeezing thiab cib clamping yuav tsum tau siv los xyuas kom meej tias cov cib yog nruj nreem spliced kom tsis txhob to. Rau cov cib loj loj, yuav tsum tau saib xyuas thaum lub sij hawm thauj mus los thiab kev teeb tsa kom tsis txhob tawg cov cib vim tsis muaj zog.
2. Kev siv cov cib
Thaum siv, xyuam xim rau kev siv cov cib. Cib yuav tsum tsis txhob overheated los yog txias sab hauv kom tsis txhob tawg. Thaum siv lub qhov cub kub kub, lub qhov cub yuav tsum tau tso cai kom sov li maj mam thaum txias kom tsis txhob muaj kev puas tsuaj rau cov cib los ntawm thermal shock thiab kub gradients.
3. Cov cib hu ua kua hlau
Thaum cov av nplaum high-alumina refractory cib tuaj rau hauv kev sib cuag nrog cov kua hlau, lawv nquag nkag mus thiab corrosion vim qhov kub thiab txias, thaj tsam loj thiab kev ntxhov siab loj. Hauv qhov no, cov txheej txheem tshwj xeeb thiab cov khoom siv yuav tsum tau siv los tiv thaiv corrosion ntawm cov cib. Thaum siv, qhov xwm txheej ntawm cov txheej txheem thiab cov khoom siv yuav tsum tau kuaj xyuas tsis tu ncua thiab hloov thiab tswj kom raws sijhawm.
4. Deal nrog cov slag rau saum npoo ntawm cib
Nyob rau saum npoo ntawm cib, qee cov hmoov tshauv feem ntau yog tsim, uas cuam tshuam rau kev zoo nkauj ntawm cov khoom. Nyob rau lub sijhawm no, nws tuaj yeem smashed los yog txiav tawm nrog rauj lossis cutter, thiab polished nrog sandpaper.
Cov saum toj no yog cov khoom uas yuav tsum tau them sai sai rau thaum siv av nplaum siab alumina refractory cib. Yog tias peb tuaj yeem siv cov av nplaum siab alumina refractory cib ua raws li cov kev ceev faj no, tsis yog lawv tuaj yeem siv lawv cov kev ua tau zoo thaum siv, tab sis lawv tuaj yeem txuas lawv lub neej kev pab cuam thiab txo cov nqi kho. Peb yuav tsum ua tib zoo saib xyuas thiab tswj xyuas cov khoom kom ntseeg tau tias kev ua haujlwm zoo ntawm cov khoom.
