Refractory Bricks yog dab tsi?

Refractory cibyog cov khoom siv ceramic uas feem ntau siv nyob rau hauv qhov kub thiab txias ib puag ncig vim nws tsis muaj combustibility thiab vim hais tias nws yog ib tug zoo insulator uas txo lub zog poob. Refractory cib feem ntau yog tsim los ntawm txhuas oxide thiab silicon dioxide. Nws tseem hu ua "hluav taws cib."

Kev sib xyaw ntawm Refractory Clay

Refractory av nplaumyuav tsum muaj ntau dua ntawm "tsis muaj mob" silicon dioxide thiabaluminiumoxide. Lawv yuav tsum muaj tsawg heev ntawm cov kua qaub, magnesium oxide, hlau oxide, thiab alkali.
Silicon Dioxide: Silicon dioxide (SiO2) softens ntawm li 2800℉ thiab thaum kawg melts thiab hloov mus rau hauv ib lub iav ntawm txog 3200℉. Nws melts ntawm ib ncig ntawm 3300℉. Qhov siab softening thiab melting point ua rau nws cov khoom tseem ceeb los ua refractory bricks.
Alumina: Alumina (Al2O3) muaj qhov softening thiab melting kub dua li silicon dioxide. Nws melts ntawm ib ncig ntawm 3800℉. Yog li ntawd, nws yog siv ua ke nrog silicon dioxide.
Txiv qaub, magnesium oxide, hlau oxide, thiab alkali: Lub xub ntiag ntawm cov khoom xyaw uas tsim kev puas tsuaj yuav pab txo cov softening thiab melting kub.

Refractory brickstuaj yeem siv los tsim kilns, furnaces, thiab lwm yam.
Lawv tuaj yeem tiv taus kub txog 2100 degrees Celsius
Lawv muaj peev xwm ua kom sov zoo kawg uas pab cov qauv sib txawv kom nyob ruaj khov hauv qhov kub thiab txias.

Kev tsim cov txheej txheem ntawm refractory bricks

Cov cib hluav taws kub yog tsim los ntawm ntau yam txheej txheem cib, xws li cov av nkos muag muag, kub nias, thiab nias qhuav. Nyob ntawm cov khoom siv ntawm cov hluav taws kub, qee cov txheej txheem yuav ua haujlwm zoo dua li lwm tus. Hluav taws cib feem ntau yog tsim rau hauv cov duab plaub nrog qhov ntev ntawm 9 ntiv tes ntev × 4 ntiv tes dav (22.8 cm × 10.1 cm) thiab tuab ntawm 1 nti thiab 3 ntiv tes (2.5 cm txog 7.6 cm).

Raw khoom npaj:
Cov khoom siv refractory: Cov khoom siv raw muaj xws li alumina, aluminium silicate, magnesium oxide, silica, thiab lwm yam. Cov ntaub ntawv raw yog proportioned raws li cov khoom thiab hom.
Binder: av nplaum, gypsum, thiab lwm yam. feem ntau yog siv los ua cov ntaub ntawv los pab cov khoom siv raw khoom sib txuas thiab tsim.
Mixing thiab sib tsoo:
Muab cov khoom nyoos npaj rau hauv cov khoom sib xyaw rau kev sib xyaw thiab sib xyaw kom ntseeg tau tias ntau yam khoom siv raw khoom sib xyaw ua ke thiab sib xyaw ua ke.
Cov khoom sib xyaw ua ke yog finely hauv av los ntawm ib tug grinder kom cov hais ntau uniform thiab zoo.
Moulding:
Cov khoom sib xyaw thiab cov khoom siv hauv av tau muab tso rau hauv pwm molding thiab tsim rau hauv cov duab ntawm cib los ntawm kev co compaction lossis extrusion molding.
Kev ziab:
Tom qab tsim, cov cib yuav tsum tau qhuav, feem ntau yog los ntawm huab cua kom qhuav los yog ziab hauv chav kom qhuav, kom tshem tawm cov dej noo ntawm cov cib.
Sintering:
Tom qab ziab, cov cib tau muab tso rau hauv lub refractory cib kiln thiab sintered ntawm qhov kub thiab txias kom hlawv tawm cov binder nyob rau hauv cov ntaub ntawv raw thiab muab cov hais los ua ib qho khoom siv.
Lub sintering kub thiab lub sij hawm sib txawv nyob ntawm qhov sib txawv raw cov ntaub ntawv thiab yuav tsum tau, thiab feem ntau yog nqa tawm nyob rau hauv lub kub kub siab tshaj 1500 ° C.

Qhov zoo ntawm kev siv Refractory cib los yog hluav taws cib

Sivrefractory bricksmuab ib tuj ntawm qhov zoo. Lawv kim tshaj li cov pa cib vim lawv qhov tshwj xeeb high-end insulating peev xwm. Txawm li cas los xij, lawv muab qee qhov tshwj xeeb zoo hauv kev pauv rau koj cov peev nyiaj ntxiv. Basic Refractory Bricks Suppliers nyob rau hauv Is Nrias teb kuj xyuas kom meej cov khoom ntawm Magnesia Bricks nyob rau hauv lub teb chaws thiab lawv muab refractory bricks nrog rau cov nram qab no zoo:

Kev rwb thaiv tsev zoo heev
Refractory bricks feem ntau yog siv rau lawv cov khoom zoo kawg nkaus insulating. Lawv thaiv kev nkag mus ntawm tshav kub. Lawv kuj ua kom cov qauv xis nyob hauv lub caij ntuj sov thiab lub caij ntuj no.

Muaj zog dua li cov cib tsis tu ncua

Refractory bricks muaj zog tshaj li cov pa cib. Yog vim li ntawd lawv thiaj li ruaj khov dua li cov cib li niaj zaus. Lawv kuj ceeb heev lub teeb.

Txhua Qhov Zoo thiab Qhov Loj
Basic Refractory Bricks Suppliers nyob rau hauv Is Nrias teb kuj xyuas kom meej cov khoom ntawm Magnesia Bricks nyob rau hauv lub teb chaws thiab lawv muaj customizable refractory bricks. Feem ntau cov tuam ntxhab thiab cov neeg muag khoom muab cov cib ua kom haum raws li qhov xav tau loj thiab qhov ntev rau cov neeg yuav khoom.

Refractory Bricks siv rau dab tsi?

Refractory bricksnrhiav daim ntawv thov nyob rau hauv qhov chaw uas thermal rwb thaiv tsev tseem ceeb heev. Qhov piv txwv no suav nrog cov cub tawg. Lawv zoo tagnrho rau yuav luag txhua qhov huab cua huab cua. Ntau tus neeg tsim khoom paub zoo txawm tias siv cov cib no hauv kev tsim vaj tsev. Nyob rau hauv tej yam kev mob kub, refractory bricks ua rau sab hauv txias thiab txias tej yam kev mob deb. Lawv kuj ua kom lub tsev sov so.
Rau cov khoom siv hauv tsev, xws li qhov cub, grills, thiab qhov cub, cov cib refractory siv feem ntau yog ua los ntawm cov av nplaum uas muaj feem ntau yog aluminium oxide thiab silicon dioxide, cov ntsiab lus uas tuaj yeem tiv taus qhov kub thiab txias. Aluminium oxide muaj qhov cuam tshuam zoo, thaum silicon dioxide yog ib qho zoo heev insulator. Qhov ntau aluminium oxide muaj nyob rau hauv kev sib xyaw, qhov kub ntawm lub cib tuaj yeem tiv taus (ib qho tseem ceeb rau kev siv hauv kev lag luam) thiab cov cib yuav kim dua. Silicon dioxide muaj lub teeb grey xim, thaum txhuas oxide muaj xim daj.

Nws yog ib qho tseem ceeb uas yuav tsum tau hais txog tias thaum tsim lossis tsim cov vaj tsev uas muaj kev sib cuag nrog hluav taws, koj yuav tsum tau saib xyuas seb cov khoom siv puas ua raws li cov cai hauv zos. Qhov no yog tus nqi me me uas yuav tsum tau them kom tsis txhob poob khoom lossis kev sib tsoo hnyav dua. Nws yog ib txwm tsim nyog mus nrhiav tswv yim los ntawm cov kws txawj thiab manufacturers.
