Polycrystalline mullite fiber ntau paj rwb thaiv kev txhim kho hluav taws xob hloov hluav taws xob thiab txo qhov kub poob
1. Txhim kho lub neej kev pab cuam ntawm rotary kiln thiab burner cib
Chaw tsim tshuaj paus ntawm polycrystalline mullite fiber ntau paj rwb thaiv: Tom qab pasting polycrystalline mullite fibers nyob rau hauv lub puab nto ntawm lub teb kiln, ncaj qha dej ntws ntawm lub cub tawg roj ntawm lub teb kiln yog txhim kho, thiab quenching thiab cua sov ntawm lub teb kiln yog cached. Qhov ntsuas kub tswj los ntawm lub qhov cub hluav taws xob tuaj yeem raug txo los ntawm 70-100 degree, tiv thaiv kev tawg thiab tshem tawm cov khoom siv refractory. Vim yog cov yam ntxwv ntawm thermal cia ignition technology, cov pa roj tom qab thermal cia muaj qhov cuam tshuam loj heev rau lub cib burner. Kev xaiv cov cuab yeej siv ua ntej lossis hauv qhov chaw pouring tshuab rau cib firing ua rau tu thiab hloov nyuaj. Yog hais tias polycrystalline mullite fibers tau muab tso rau ntawm qhov chaw ntawm lub qhov cub cib, nws yuav txo cov nplaim hluav taws kub hnyiab ntawm lub cib cib thiab tiv thaiv nws zoo. Tom qab nws tus kheej pasting fibers, lub burner cib tsuas pom cov kab nrib pleb me ntsis tom qab tau thov rau 2 xyoos, thiab nws cov kev pab cuam lub neej yuav txuas ntxiv mus rau ntau tshaj 4 xyoo.
2. Txhim kho hluav taws xob hloov hluav taws xob thiab txo cov cua sov
Polycrystalline mullite fiber ntau paj rwb thaiv cov chaw tsim tshuaj paus: Txoj kev hloov tshav kub nyob rau hauv qhov chaw kub kub ntawm lub qhov cub cua sov yog feem ntau hluav taws xob hloov hluav taws xob, thiab cov hluav taws xob hluav taws xob hloov hluav taws xob yog nqa tawm ntawm lub qhov cub hluav taws xob, lub qhov cub lub qhov ncauj, thiab cov hlau rhuab. Lub luminosity ntawm lub qhov cub qhov cub feem ntau yog 0.8. Lub luminosity ntawm polycrystalline mullite fibers yog 0.95. Nyob rau hauv tib lub cua sov tej yam kev mob, qhov nce nyob rau hauv luminosity tom qab pasting polycrystalline mullite fibers tsub kom lub hluav taws xob cua sov nyob rau hauv lub cub tawg, yog li txhim kho cov cua kub ceev ntawm hlau thiab cov cua sov theem ntawm lub cub tawg.
Chaw tsim tshuaj paus ntawm polycrystalline mullite fiber ntau paj rwb thaiv: Raws li qhov ntsuas kub ntawm qhov chaw nyob ntawm ntau lub ntsiab lus tom qab kho thiab kev tu thiab tu tom ntej, kev poob qis ntawm polycrystalline mullite fibers tau kuaj xyuas. Nyob rau tib lub sijhawm tswj kev ntsuas kub, tom qab ua cov polycrystalline mullite fibers, qhov nruab nrab ntawm qhov kub ntawm cov phab ntsa ntawm lub cub tawg tau txo qis los ntawm 34.8 degree, txo cov cua sov ntawm lub cub tawg thiab txhim kho thermal efficiency ntawm lub cub tawg. Nyob rau tib lub sijhawm, nrog kev txhim kho ntawm chaw ua haujlwm ib puag ncig, nws tau ntxiv kev yooj yim rau kev saib xyuas, tshuaj xyuas, thiab kev ua haujlwm ntawm cov neeg ua haujlwm.
3. Txo thermal inertia, txhim kho efficiency thiab cua sov zoo
Polycrystalline mullite fiber ntau paj rwb thaiv cov chaw tsim tshuaj paus: Lub caj npab ntawm qhov kub thiab txias ntu ntu ntawm lub qhov cub cua sov yog ua los ntawm cov khoom siv refractory casting, uas tuaj yeem compacted nrog yas nyob rau hauv lub rotary kiln. Cov khoom siv refractory siv muaj cov thermal conductivity siab, thiab lub burner txais ib txoj kev cia thermal cia combustion. Ntawm qhov tod tes, qhov no nyob ntawm qhov muaj qee yam lag luam tshwm sim hauv cov cua kub cua sov thaum lub sijhawm kub nce thiab txo qis. Ntawm qhov tod tes, polycrystalline mullite fibers tuaj yeem txo cov thermal conductivity thiab thermal conductivity ntawm lub cub tawg, ua kom kub nce thiab txo qis, thiab txo cov thermal inertia, uas yog qhov zoo rau kev tsim khoom. Vim qhov txo qis hauv lub sijhawm cua sov ntawm cov khoom siv raw, huab cua oxidation thiab carburization ntawm cov khoom siv hauv cov cua kub cua sov txo qis, ua kom cov cua sov zoo ntawm cov khoom siv raw.
