Cov txheej txheem ntws ntawm refractory cib manufacturers los tsim silica bricks

Cov khoom siv raw ntawm silica cib yog silica, khib nyiab cib, txiv qaub, mineralizers thiab organic binders. Qhov sib ntxiv ntawm cov khib nyiab silica cib tsis tsuas yog txo cov combustion expansion ntawm cov cib, tab sis kuj txo qhov hluav taws kub thiab lub zog ntawm cov khoom. Yog li ntawd, Henan refractory cib manufacturers tau txiav txim siab raws li qhov sib txawv. Lub hauv paus ntsiab lus yog tias qhov loj dua qhov hnyav ntawm cov khoom, qhov nyuaj ntawm cov duab thiab ntau ntxiv. Feem ntau tswj tsis pub dhau 20%.

Txiv qaub yog ntxiv rau cov khoom tsis zoo nyob rau hauv daim ntawv ntawm cov mis nyuj ntawm txiv qaub. Cov mis nyuj ntawm txiv qaub ua raws li kev sib khi, ua kom lub zog tom qab ziab, thiab ua raws li cov ntxhia hauv cov txheej txheem combustion. Qhov zoo yuav tsum tau 90% active Cao, tsis ntau tshaj 5% carbonate, thiab ib tug thaiv qhov loj ntawm txog 50 hli. Cov mineralizer siv nyob rau hauv ntau lawm yog tsuas yog dov steel nplai. Qhov kev xav tau zoo yog tias cov ntsiab lus ntawm cov hlau oxide ntau dua 90%, uas yuav tsum tau pulverized nrog lub pob zeb, thiab ib feem nrog qhov me me ntawm tsawg dua 0.088mm yuav tsum suav rau ntau dua 80%.

Cov organic binder feem ntau yog sulfite slurry pov tseg kua.

Muaj plaub lub hauv paus ntsiab lus rau kev txiav txim siab cov khoom ntawm silica cib;

1) Thaum xaiv qhov loj me me, qhov ruaj khov ntawm qhov siab tshaj plaws thiab qhov kub ntawm qhov sib xyaw yuav tsum tau ua kom ntseeg tau;

2) Nws xav tias cov khoom tseem ceeb hauv cov khoom tsis zoo yog me me thiab cov khoom zoo yog ntau dua;

3) Thaum siv cov sib tov sib txawv ntawm cov silica, ntxiv cov khoom ntxhib ntawm qhov kub thiab cov khoom zoo ntawm qhov kub tsawg;

4) Rau silica raw cov ntaub ntawv nrog ntom ntom ntom, cov khoom tuaj yeem ua coarser, txwv tsis pub finer.

Kev xyaum ntau lawm qhia tau hais tias qhov loj me me ntawm cov silica cib zoo tib yam yog 2 ~ 3 hli, thiab thaum vein quartz siv los ua cov khoom siv raw, qhov siab tshaj plaws particle loj yog li 2 hli.

Cov yam ntxwv molding ntawm silica bricks yog feem ntau xav txog nyob rau hauv peb yam: lub molding yam ntxwv ntawm cov dawb paug, complex cov duab ntawm lub cib puab thiab qhov sib txawv loj nyob rau hauv ib tug zoo.

Silicon billet yog cov khoom siv yas tsawg, yog li lub siab molding yuav tsum tau nce kom tsim nyog. Coke cub silica cib muaj cov duab nyuaj, ib qho hnyav, thiab qee qhov muaj qhov tuab ntawm 160mm, yog li nws yog qhov zoo tshaj plaws los siv ob sab molding. Yog tias txoj kev vibration qauv tau txais yuav, nws qhov zoo yog pom tseeb dua. Silica cib yuav nthuav dav hauv ntim thaum lawv raug rho tawm haujlwm, yog li qhov loj ntawm cib pwm yuav tsum raug txo kom haum.

Silicon cib yuav dhau mus rau theem hloov pauv thaum lub sijhawm tua hluav taws, uas ua rau muaj teeb meem rau kev tua. Yog li ntawd, kev hloov pauv ntawm lub cev thiab tshuaj lom neeg ntawm lub cev kiln, cov duab thiab qhov loj ntawm lub cev tsis zoo, thiab cov yam ntxwv ntawm lub cev kiln yuav tsum raug txiav txim siab.

1) Thaum qhov kub thiab txias qis dua 600 ℃, qhov kub yuav tsum tau nce sai thiab sib npaug;

2) 700 ~ 1100 ℃ cua sov tus nqi nrawm dua li qub;

3) Nyob rau hauv qhov kub ntawm 1100 ~ 1430 ℃, qhov cua sov yuav tsum maj mam txo;

4) Tsis muaj zog txo cov nplaim hluav taws kub hnyiab yog siv nyob rau hauv qhov kub thiab txias, thiab qhov kub thiab txias hauv qhov cub tau sib npaug sib npaug kom tsis txhob muaj kev puas tsuaj rau lub cev cib los ntawm cov nplaim taws. Tom qab ncav cuag qhov siab tshaj plaws sintering kub, yuav tsum muaj lub sijhawm tuav txaus, thiab lub sijhawm tuav hloov pauv ntawm 20 ~ 48h;

5) Nws tuaj yeem ua kom txias sai dua 600 ~ 800 ℃, thiab nws yog qhov zoo dua kom txias qeeb ntawm qhov kub qis.
