Silica Refractory Cib

Txhawm rau tiv thaiv kev hloov pauv crystalline hauv Silica Refractory Brick thaum lub sijhawm tua, nrog rau cov ntim loj hloov ua rau muaj kev tawg, cov txheej txheem hauv qab no yuav tsum tau ua.

Khoom Description

Lub cev thiab tshuaj hloov pauv ntawmsilica cibthaum lub sij hawm tua hluav taws. Cov silica cib tau txais cov kev hloov pauv hauv qab no hauv qhov kub thiab txias thaum lub sijhawm tua hluav taws: cov dej seem seem tawm ntawm cov cib qis dua 150 degree, thiab Ca(OH)2 pib decompose ntawm 450 degree; Ntawm 450 ~ 500 degree, lub cev qhuav dej ntawm Ca (OH) 2 ua tiav, kev sib xyaw ntawm silica hais thiab txiv qaub raug rhuav tshem, thiab lub zog ntawm lub cev ntsuab tau txo qis heev. Nyob rau hauv qhov ntau ntawm 550 ~ 650 degree, -quartz transforms rau hauv -quartz. Txij li cov txheej txheem hloov pauv tau nrog lub ntim nthuav dav ntawm 0.82%, quartz siv lead ua yuav muaj cov kab nrib pleb nrog ntau qhov sib txawv. Nyob nruab nrab ntawm 600 thiab 700 degree, cov tshuaj tiv thaiv theem ntawm CaO thiab SiO2 pib, thiab lub zog ntawm lub cib nce. Pib los ntawm 1100 degree, kev hloov pauv ceev ntawm quartz nce zoo heev thiab qhov tshwj xeeb lub ntiajteb txawj nqus ntawm cov cib kuj txo qis. Nyob rau lub sijhawm no, qhov ntim ntawm cov cib nce siab heev vim kev hloov pauv ntawm quartz mus rau qhov tsis tshua muaj qhov sib txawv ntawm qhov sib txawv. Txawm hais tias cov kua theem kuj tseem nce ntxiv rau lub sijhawm no, cov kab nrib pleb tseem tuaj yeem tshwm sim hauv thaj tsam ntawm 1100 ~ 1200.

(1) Nws yog ib qho tsim nyog los tswj cov cua kub ntawm qhov sib txawv ntawm qhov kub thiab txias. Cov cua kub qeeb qeeb thaum nws qis dua 600 degree. Cov cua kub tuaj yeem nrawm dua thaum nws nyob nruab nrab ntawm 600 thiab 1000 degree. Cov cua kub yuav tsum qeeb thaum nruab nrab ntawm 1100 thiab 1300 degree. Thaum nws nyob nruab nrab ntawm 1300 degree thiab qhov kub ntawm qhov hluav taws kub (1430 degree txog 1450 degree), qhov cua sov yuav tsum yog qhov siab tshaj plaws thaum lub sijhawm tua hluav taws. Qhov qeeb tshaj ntawm lawv. Cov silica bricks raug rho tawm haujlwm yuav tsum tau txias hauv qab 600 degree, tshwj xeeb tshaj yog maj mam ntawm 300 degree. Qhov no tuaj yeem cuam tshuam qhov ntim hloov pauv ntawm crystalline hloov pauv, ua rau cov ntsiab lus tridymite thiab cristobalite siab dua, thiab zam kev tsim cov kab nrib pleb.

(2) Kev txo qhov cua yuav tsum tau siv nyob rau hauv qhov kub-kub tua hluav taws theem kom yooj yim rau cov ntxhia hauv cov nqi qis ntawm cov hlau oxide thiab txhawb kev tsim loj ntawm tridymite. Txwv tsis pub, nyob rau hauv ib qho chaw oxidizing, tshwj xeeb tshaj yog thaum cov mineralizer tsis txaus, -quartz feem ntau hloov dua siab tshiab rau hauv -cristobalite. Qhov kev hloov pauv no hu ua "kev hloov pauv qhuav". Thaum lub sij hawm qhuav hloov dua siab tshiab, vim qhov ntim tsis sib npaug ntawm cov cib thiab tsis muaj cov kua tsis muaj kev ntxhov siab, cov qauv ntawm cov khoom yuav xoob thiab tawg. Nyob rau tib lub sijhawm, kev rwb thaiv tsev tsim nyog yuav tsum tau nqa tawm ntawm qhov sib txawv ntawm qhov kub thiab txias ntawm silica cib firing kom covsilica cibmuaj cov theem tsim nyog muaj pes tsawg leeg thiab ua tau raws li qhov yuav tsum tau siv.

(3) Txhim kho cov khoom thauj khoom ib nrab kom txo tau qhov tshwm sim ntawm cov kab nrib pleb. Cov kab nrib pleb hauv silica cib, uas yog, cov kab nrib pleb sib npaug rau cov kev taw qhia siab ntawm cov khoom, feem ntau tshwm sim los ntawm cov cua kub tsis sib xws ntawm ntau qhov chaw thaum cov khoom raug rho tawm haujlwm. Lawv feem ntau tshwm sim ntawm qhov hluav taws kub sab nraum lub cib pawg, tshwj xeeb tshaj yog nyob rau saum npoo ntawm cov khoom. Raws li rau cov kab nrib pleb nyob rau saum npoo ntawm silica bricks, ntxiv rau qhov microscopic unevenness ntawm lub cev ntsuab nws tus kheej vim tsis sib xws kneading los yog hloov ntawm raw cov ntaub ntawv, nws yog feem ntau yog tshwm sim los ntawm cov khoom raug rhuab mus rau ib tug overheating kub thiab loj. kev hloov pauv. Thaum thauj khoom, qhov tshwj xeeb-zoo li silica cib yuav tsum tau muab tso rau hauv lub tsheb kiln, thiab cov qauv zoo tib yam cib yuav tsum tau muab ntsia rau sab nraud ntawm lub tsheb kiln; lub protruding qhov chaw ntawm qhov tshwj xeeb-zoo li tus cib los yog qhov chaw uas yuav ua rau tawg yuav tsum nyob rau hauv; sab saum toj ntawm lub tsheb kiln yuav tsum tau them nrog ib co Nyias cib kom tsis txhob muaj kev cuam tshuam ncaj qha ntawm cov nplaim taws, txwv tsis pub nws yuav ua rau muaj kev tawg ntxiv.
