Kev xaiv txuj ci ntawm Lub teeb yuag refractory rwb thaiv tsev cib

Lub teeb thermal rwb thaiv tsev cib yog lub teeb hauv qhov hnyav. Lawv tuaj yeem siv rau hauv qhov chaw thermal rwb thaiv tsev kom insulate thiab txo cov suab nrov. Tsis tas li ntawd, thermal rwb thaiv tsev tuaj yeem txo cov roj noj ntawm qhov cub thiab txo cov nqi tsim khoom. Qhov loj npaum li cas ntawm lub teeb yuag thermal rwb thaiv tsev cib muaj xws li cov nplaum nplaum nplaum thiab lub teeb yuag siab alumina cib, tab sis yuav ua li cas xaiv cov nplaum nplaum nplaum nplaum thiab lub teeb yuag siab alumina cib? Tau kawg, muaj qee qhov kev txawj ntse.

Kev xaiv ntawm lub teeb yuag refractory rwb thaiv tsev cib yuav tsum xub xav txog lub zog, cov ntsiab lus txhuas, av qeeg thiab impermeability. Thaum xaiv lub teeb yuag refractory bricks, peb yuav tsum xub to taub lawv cov yam ntxwv. Cov ntsiab lus ntawm txhuas ntawm lub teeb av nplaum cib yog li 30-35%. Raws li ib txwm muaj, qhov kev siv zog yog 3-4Mpa.

Koj tuaj yeem tshawb xyuas cov av nplaum nplaum ua ntej. Tau kawg, cov txheej txheem xaiv tuaj yeem paub los ntawm qhov chaw lossis qee cov ntsiab lus.

Thaum xaiv cov nplaum nplaum nplaum nplaum, ua ntej saib seb lub ntsej muag ntawm lub teeb ci ci zoo li xim. Yog tias cov xim tsis sib xws, nws txhais tau tias qhov kub thiab txias yog qhov ruaj khov thiab thermal shock yuav zoo. Tom qab ntawd tuav lub ntug ntawm lub cib nrog koj txhais tes kom pom tias cov hmoov nplej poob. Yog tias nws tsis poob tom qab nias nyuaj, nws txhais tau tias lub zog tuaj yeem tshaj 3Mpa. Tom qab ntawd qhib ib daim av nplaum cib kom pom tias nws yog sandwiched. Yog hais tias lub qhaub cij tshwm daj los yog liab, nws txhais tau hais tias lub teeb av nplaum cib tsis tau hlawv thiab permeability tsis zoo. Yog hais tias qhov qhib yog tib yam li saum npoo, nws txhais tau hais tias lub zog thiab kev poob siab tsis kam ntawm lub teeb ci av nplaum yog OK, thiab koj tuaj yeem yuav nws nrog kev ntseeg siab.

Lub teeb yuag siab alumina cib yog lub teeb hauv qhov hnyav thiab muaj qhov kub siab ua haujlwm zoo hauv thaj chaw thermal rwb thaiv tsev. Lawv yog cov kim tshaj li cov av nplaum ci ci, tab sis lawv kuj siv rau qhov kub thiab txias. Nws muaj kev ua haujlwm zoo thermal rwb thaiv tsev thiab yog 10 npaug zoo dua li cov thermal rwb thaiv tsev zoo tib yam. Cov ntsiab lus txhuas ntawm lub teeb yuag high-alumina cib yog ntau tshaj 40-45%, lub zog yog 6-7Mpa, thiab xim yog xim dawb dua li lub teeb av nplaum cib. Zoo, lwm qhov yog ntsuas qhov loj los saib seb nws puas ua tau raws li kev tswj hwm ntawm lub cib loj los siv. Tom qab ntawd qhib ntu ntawm lub teeb yuag high-alumina cib kom pom tias nws yog sintered kom huv si. Yog hais tias lub teeb yuag high-alumina cib muaj tib xim sab hauv thiab sab nraud, nws qhia tau hais tias lub zog thiab kev txuag hluav taws xob zoo.

Tau kawg, kev xaiv ntawm cov khoom siv hluav taws xob rwb thaiv tsev no yuav tsum muaj kev nkag siab ntawm cov ntaub ntawv refractory. Yog tias nws tsis meej heev, nws yog txoj hauv kev tshuaj xyuas, tab sis qee qhov ntawm cov lus qhia saum toj no tuaj yeem xaiv qhov yooj yim thiab yooj yim txoj kev ntawm lub teeb yuag refractory bricks.
