Qhov hluav taws kub kub ntawmsiab alumina cibtseem ceeb heev. Yog tias qhov hluav taws kub kub qis qis, cov xim yuav daj daj, thiab lub ntsej muag zoo nkauj yuav zoo nkauj, tab sis cov nyhuv siv yuav tsis zoo li qhov kub thiab txias.
High alumina refractory bricks raug rho tawm haujlwm ntawm qhov kub thiab txias, thiab cov xim raug rho tawm haujlwm yog xim daj thiab dawb. Cov xim saum npoo tsis zoo li zoo li cov raug rho tawm ntawm qhov kub thiab txias, tab sis cov nyhuv siv tau zoo, vim tias qhov kub ntawm bauxite raw khoom nws tus kheej kuj yog stretchable, thiab lwm yam expansion yuav tshwm sim thaum kub qis. phenomenon, cuam tshuam rau ib txwm siv lub voj voog.
1. Lub sintering kub nyob ntawm raw khoom nws tus kheej
Lub sintering kub ntawm siab alumina bricks nyob ntawm raw cov ntaub ntawv lawv tus kheej. Qhov ntsuas kub sintering yog txiav txim siab raws li cov khoom siv raw. Lub sintering kub uas siab dhau yuav ua rau cov cib deform. Lub sintering kub uas tsawg dhau yuav ua rau cov cib tsis muaj zog. Thiab nws tsis hnav-resistant thiab yooj yim rau tev tawm.
Feem ntau cov tuam txhab refractory yuav cov khoom siv raw thiab tom qab ntawd txiav txim siab ntawm ntau txheej txheej txheej txheem rau kev tua hluav taws. Raws li qhov kev sim tua hluav taws, lawv txiav txim siab cov txheej txheem tsim khoom tsim nyog tshaj plaws thiab tsim nyog sintering kub. Qhov no yuav xyuas kom meej tias qhov kub thiab txias ntawm cov khoom siv hluav taws xob siab alumina yog tsim nyog. , thiab cov xim nto thiab sab hauv zoo tswj qhov kev siv kom zoo.
2. Lub rotating kiln siv tsis tau zoo.
Yog hais tias qhov kub ntawm sintering qis dua me ntsis, cov hluav taws kub alumina cib yuav zoo zoo thiab muaj qhov sib xws. Lawv tsuas yog siv tau rau cov vuas phab ntsa thiab cov kab hluav taws xob zoo li qub. Yog hais tias nws yog ib tug rotating rotary kiln, nws yuav siv tsis tau zoo vim hais tias thaum lub sij hawm kev sib hloov txheej txheem, High aluminium bricks nyob rau hauv qis kub yuav nthuav thiab cog lus rau ib tug thib ob lub sij hawm. Thaum lub cev kiln nthuav dav thiab cog lus ntawm qhov kub siab, cov cib yuav nthuav dav thiab nthuav dav rau lub sijhawm thib ob, uas tuaj yeem yooj yim ua rau lub siab alumina refractory cib kom tev tawm.
Yog hais tias lub siab alumina cib raug rho tawm haujlwm ntawm qhov ntsuas kub, txawm hais tias cov xim ntawm cov cib raug rho tawm haujlwm yuav tsaus, thaum siv hauv cov txheej txheem rotating kiln, cov nyhuv yuav zoo dua li cov cib refractory uas muaj xim zoo thiab kub me ntsis, thiab lub neej kev pabcuam yuav ntev dua. Vim tias thaum kub kub, cov khoom siv raw raug hlawv kom tuag thiab shrinkage yuav tsis tshwm sim, thiab cov nyhuv siv yuav zoo dua.
