Kev tsim kho ntawm high aluminium refractory castable yuav tsum nruj me ntsis kom ntseeg tau tias lub cev zoo ntawm cov ntaub ntawv pouring. Ua ntej kev tsim kho ntawm qhov cub, qhov zoo ntawm cov khoom siv tau zoo heev, tab sis nws tsis ua raws li qhov yuav tsum tau ua tom qab daim ntawv thov, uas yog feem ntau cuam tshuam nrog kev tsim kho, tu thiab ci.
Pom tias qhov chaw ntog yog qhov loj, yog tias nws me me, siv qee phaus lossis yas los kho nws, tab sis koj yuav tsum xub ntxuav qhov chaw sib cuag. Hauv qab no yuav piav qhia rau koj txog cov txheej txheem tshwj xeeb:
(1) Xaiv cov khoom siv thiab cov khoom siv vuam kom raug kom tsis txhob muaj cov khoom seem poob
Vim yog cov hlau sib txawv, cov thauj tog rau nkoj, thiab cov khoom siv hluav taws xob ntawm cov khoom siv hluav taws xob, cov khoom siv hluav taws xob nthuav dav ntawm txhua qhov ntawm txhua qhov tsis sib xws thaum siv cov cua sov, uas ua rau muaj kev ntxhov siab loj heev, uas tuaj yeem yooj yim ua rau tawg ntawm. solder pob qij txha, ua rau lub thauj tog rau nkoj thiab pouring. Yog li ntawd, thaum xaiv thauj tog rau nkoj thiab ceg txheem ntseeg, koj yuav tsum xyuam xim rau tib yam li cov hlau phaj khoom ntawm cov khoom siv kiln kom tsis txhob tawg cov pob qij txha vim qhov sib txawv ntawm qhov sib txawv. Tsis tas li ntawd, sim siv ib lub thauj tog rau nkoj los yog ua kom qhov ntev ntawm cov vuam pob qij txha kom ntau li ntau tau los ua kom cov vuam khov kho. Yog tias "y"-shaped thauj tog rau nkoj tuaj yeem hloov tau nrog "L" zoo li, thiab txawm tias "L" zoo li "X" welded, nws tuaj yeem ua kom lub peev xwm ruaj khov ntawm cov thauj tog rau nkoj thaum cov khoom ntim yog nyias los tiv thaiv kev poob. .
(2) Txhim kho kev tsim kho kom zoo
Ua ntej kev tsim kho ntawm cov castable, cov cheeb tsam ib puag ncig thiab ib puag ncig yuav tsum tau ua kom huv si txhawm rau tiv thaiv cov tub yees thiab cov khoom siv refractory ntawm cov khoom tsis meej. Cov cuab yeej siv thiab khoom siv yuav tsum tau ua kom huv si. Yog tias siv cov dej-resistant refractory castable ntau dua, qhov sib thooj fluidity tsis zoo, thiab cov kev hloov pauv yuav muaj qee yam cuam tshuam rau kev tsim kho. Raws li qhov no, ib qho kev nce hauv dej ntim yuav txo qhov kev siv ntawm castable. Yog li ntawd, txhawm rau txhawm rau txhim kho kev tsim kho, qee tus neeg ua haujlwm nce cov dej ntawm qhov xav tau, ua rau poob qis hauv kev ua haujlwm ntawm cov dej ntws. Ntxiv nrog rau kev ntxiv dej, lub sijhawm sib tov yog ntxiv. Lub liquidity ntawm castable yuav tsum tau ua si tom qab nplawm rau ib lub sij hawm (kwv yees li 3 feeb), yog li nws yuav tsum tau ua raws li cov lus piav qhia ntawm refractory castable. Qhov no xav kom lub Hoobkas lees txais cov txheej txheem ua haujlwm ntawm txhua qhov txuas tshwj xeeb hauv cov txheej txheem masonry ua ntej kev tsim kho.
(3) Kev tu thiab ci qhov system.
Kev tu thiab ci kuj yog ib qho tseem ceeb cuam tshuam rau kev ua tau zoo ntawm aluminium refractory castable. Kev saib xyuas yog muab lub sijhawm sib koom tes thiab ua kom tawv nqaij ntawm tus neeg sawv cev khi rau hauv cov khoom nchuav kom tau txais kev siv zog txaus txaus. Tus yuam sij rau kev tswj xyuas thaum lub sij hawm tu yog cov av noo ntawm lub pouring (yuav tsum tau khaws cia noo), qhov kub thiab txias (yuav tsum yog ntawm 15-35 degree C) thiab lub sij hawm. Tom qab ci yog hardening, nws evaporates cov dej ntxiv, txhawb cov txheej txheem sintering ntawm qhov kub thiab txias kom ntxiv dag zog rau lub cev ntawm lub cev. Thaum lub sij hawm ci, tus nqi cua sov feem ntau yog tswj, feem ntau yog 15-35 degree C ib teev. Thaum qhov kub pib, nws tsis tuaj yeem cuam tshuam lossis nres cua sov, kom txog thaum lub cua sov dhau. Txwv tsis pub, nws yuav tsum tau ceev faj heev kom txias rau hauv lub qhov cub, thiab thaum lub cua sov dua, nws yog ib qho tsim nyog yuav tau ua raws li cov kauj ruam tau teev tseg.
Txawm li cas los xij, nyob rau hauv cov txheej txheem tsim khoom tiag tiag, qhov ua rau ntawm kev tiv thaiv-refractory castable ntawm high aluminium thiab cov kev daws teeb meem yuav tsis tsuas yog hais saum toj no, yog li tshwj xeeb tshuaj xyuas thiab tswj nws hloov pauv raws li qhov xwm txheej tshwj xeeb los xyuas kom meej tias nws ua tiav cov txiaj ntsig zoo. .
