Dab tsi yog Cov Txheej Txheem Rau Pouring Cub Nrog Granular Refractory Fiber Castables?

Granular refractory fiber castable yog cov khoom siv tau zoo, lub teeb yuag thiab txuag hluav taws xob, uas yog siv dav hauv kev lag luam furnaces, qhov cub thiab lwm qhov chaw. Yuav ua li cas yog txoj kev rau pouring ncu nrog refractory granular fiber castables? Topoqwe qhia txoj kev rau pouring qhov cub:

Hu rau tam sim no

1. Kev npaj ua haujlwm:
Ua ntej pib pouring, cov kev npaj hauv qab no yuav tsum tau ua:

Xyuas seb lub hauv paus ntawm qhov cub puas ruaj khov thiab xyuas kom meej tias lub hauv paus tsis co;
Ntxuav lub hauv paus nto kom ntseeg tau tias tsis muaj teeb meem txawv teb chaws;
Npaj cov ntaub ntawv thiab cov cuab yeej xws li granular refractory fiber castables, sib tov cov cuab yeej, vibrators;
Txiav txim siab qhov feem ntawm castables thiab tus nqi ntawm cov dej.
2. stirring cov castables: Ntxiv cov granular refractory fiber castables rau ib tug tsim nyog tus nqi ntawm cov dej raws li qhov kev faib ua feem, thiab siv ib tug sib tov cuab tam rau do kom huv si. Lub sij hawm nplawm yog li ntawm 5-10 feeb kom txog thaum cov castables tag nrho sib xyaw.

3. Pouring: Ncuav cov khoom sib xyaw refractory granular fiber ntau castable rau hauv cov pwm npaj, thiab siv lub vibrator kom vibrate kom tshem tawm cov npuas npuas thiab ua kom cov castable ntau ntom.

4. Kev tu: Tom qab nchuav tiav lawm, muab cov pwm tso rau hauv qhov chaw cua thiab qhuav rau kev tu. Granular refractory fiber castables tu lub sij hawm feem ntau yog 24-48 teev.

5. Demoulding: Tom qab kev kho tiav lawm, demould lub pwm kom tau lub ncuav granular refractory fiber ntau qhov cub.

6. Ci: Muab lub qhov cub tso rau hauv qhov cub rau ci. Qhov kub thiab lub sijhawm ci yog txiav txim siab raws li cov khoom siv tshwj xeeb.

Los ntawm cov kauj ruam saum toj no, peb tuaj yeem tau txais cam khwb cia granular refractory fiber ntau qhov cub. Qhov cub no muaj qhov zoo ntawm kev ua haujlwm zoo thermal rwb thaiv tsev, lub zog siab, tsis tshua muaj thermal conductivity, thiab lwm yam, thiab tuaj yeem siv dav hauv ntau lub tshuab cua sov, qhov cub thiab lwm yam.
