Lub qhov cub kub kub saum toj kawg nkaus tuaj yeem muab faib ua peb ntu: thaj chaw nruab nrab thiab qis qis ntawm lub tshuab hluav taws xob qis, qhov kub thiab txias ntawm lub tshuab hluav taws xob sab saud, thiab lub khob hliav qab combustion chamber thiab thaj chaw burner.
Lub tshuab hluav taws xob ntawm lub qhov cub kub kub saum toj kawg nkaus tuaj yeem muab faib ua ob ntu: lub tshuab hluav taws xob, lub combustion chamber thiab thaj chaw burner. Cov hauv qab no feem ntau yog hais txog kev ua hauj lwm hauv paus ntsiab lus thiab cov khoom siv refractory configuration ntawm lub regenerator ntawm kub blast rauv.
Lub tshuab regenerator tau muab faib ua peb ntu: thaj chaw kub qis, thaj chaw nruab nrab kub thiab qhov kub siab. Vim muaj qhov sib txawv ntawm qhov chaw ua haujlwm thaum lub sijhawm ua haujlwm, lubrefractory cibkhoom configuration siv kuj txawv.
1. Tsis tshua muaj qhov kub thiab txias
Kev khiav hauj lwm kub ntawm qhov chaw qis qis ntawm lub tshuab regenerator yog tsawg dua 900 degree. Nws lub luag haujlwm tseem ceeb yog los dais lub ntiajteb txawj nqus ntawm cov masonry sab saud thiab muaj zog convection cua sov txheej txheem ntawm thawj theem ntawm huab cua. Cov kev cai rau cov ntaub ntawv refractory nyob rau hauv cheeb tsam no tsis siab dhau, thiab cov khoom uas muaj thermal shock kuj yuav tsum tau. Ordinary av nplaum cib raug pom zoo.
2. Qhov chaw nruab nrab kub
Qhov kub thiab txias nyob rau hauv nruab nrab cheeb tsam ntawm lub regenerator feem ntau fluctuates ntawm 800-1100 degree . Qhov chaw no yog hu ua qhov kev hloov pauv ntawm thaj chaw kub siab thiab thaj chaw kub tsawg. Daim ntawv thov ntawm nws cov refractory bricks yuav tsum tau zoo siab kub creep zog. Nws raug nquahu kom siv qis creep siab alumina cib lossis qis creep av nplaum cib.
3. Qhov kub thiab txias cheeb tsam
Nyob rau sab sauv ntawm lub regenerator, vim qhov kub thiab txias thiab hloov pauv, cov khoom siv refractory xaiv yuav tsum muaj thermal stability zoo. High alumina bricks yog txwv nyob rau hauv lawv siv nyob rau hauv cheeb tsam no vim lawv tus kheej creep zog thiab expansion yam ntxwv.
Andalusite cib yog qhov kev xaiv zoo tshaj plaws hauv cheeb tsam no hais txog kev ua tau zoo. Lawv muaj qhov zoo ntawm cov refractoriness siab, siab load softening kub, zoo kub stability thiab zoo thermal shock kuj, tab sis tus nqi ntawm andalusite bricks yog kuj siab.
Hauv kev siv tiag tiag, muaj ntau dua thiab ntau dua ntawm kev siv silica refractory cib hauv cheeb tsam no. Silica bricks muaj qhov zoo ntawm qhov zoo thermal expansion thiab siab load softening point, tab sis piv nrog andalusite bricks, lawv muaj tsis zoo los tiv thaiv stripping kev ua tau zoo thiab me ntsis txo tshav kub cia. Yog tias cov silica cib siv rau hauv cov txheej txheem ua haujlwm ntawm qhov chaw kub kub nyob rau sab saum toj ntawm lub qhov cub kub kub, lub teeb silica bricks haum rau cov khoom ntawm cov txheej txheem ua haujlwm yuav tsum tau xaiv raws li cov txheej txheem rwb thaiv tsev.
