Hauv kev tsim thiab siv cov txiv qaub teb kilns,refractory castablesteeb meem tau muab faib ua ob pawg: ib qho yog qhov teeb meem ntawm castable solidification ceev thaum tsim kho; lwm yam yog castable zoo teeb meem uas tshwm sim thaum lub sij hawm ntau lawm txheej txheem.
(1) Thaum tsim cov hloov chute thiab kiln tail castables, nws tau pom tias cov castables tseem tsis muaj zog tom qab ob peb hnub ntawm kev tsim kho, ua rau rov ua haujlwm ntawm cov castables hauv cheeb tsam no.
Kev tsom xam teeb meem: Vim muaj ntau yam laj thawj, qhov project tau ncua sij hawm ntau lub hlis. Txawm li cas los xij, tus neeg xa khoom castable tau muab cov castables raws li lub sijhawm cog lus ib txwm. Tsis tas li ntawd, cov av noo siab ntawm qhov chaw ncaj qha ua rau cov castables tsis ua kom muaj zog vim cov cement tsis ua haujlwm thiab poob lub zog. Tom qab hu rau cov chaw tsim khoom, cov cement tau rov muab dua, tab sis cov castable solidified sai heev dua. Yog vim li cas yog tias lub tshuab tov khoom nyob deb ntawm qhov chaw tsim kho. Tom qab cov castables tau sib xyaw, lawv pib ua kom khov ua ntej xa mus rau qhov chaw tsim kho, cuam tshuam rau kev tsim kho kom zoo.
Kev daws: Xa cov khoom sib tov me me rau hauv qhov cub, sib tov cov khoom siv hluav taws xob ncaj qha rau ntawm qhov chaw tsim kho, thiab pib tsim kho tam sim tom qab sib tov, uas txuag lub sijhawm ntawm kev thauj mus los thiab tau ua tiav cov txiaj ntsig pom tseeb.
(2) Thaum lub sij hawm tsim cov txheej txheem, cov castables ntawm lub hloov chute ntawm plaub lub teb kiln tau hnav thiab poob ntau zaus. Qhov kub hauv cheeb tsam hauv nruab nrab thiab qis ntawm qhov hloov chute maj mam nce, ncav cuag 600 degree, thiab sab nraud steel phaj yog xim liab. Tom qab nres lub qhov cub thiab saib xyuas hauv qhov cub, nws pom tias cov castables ntawm qhov chaw no tau hnav tawm, nthuav tawm cov phaj hlau, thiab cov thauj tog rau nkoj kuj tau polished.
Lub refractory castables nyob rau hauv cheeb tsam no yog tag nrho cov qis-cement castables nrog alumina cov ntsiab lus ntawm 70%, thiab yav dhau los 400t·d-1 thiab 600t·d-1 kilns kuj siv castables nrog tib lub cev thiab tshuaj. ntsuas, thiab tsis muaj teeb meem zoo sib xws. Tom qab cov castable poob lawm, cov chaw tsim khoom castable kuj tau xa cov kws tshaj lij mus rau qhov chaw ua haujlwm ntau zaus, tab sis tsis pom muaj kev daws teeb meem zoo dua. Txhawm rau kom tsis txhob cuam tshuam rau Anshan Hlau thiab Hlau cov kev xav tau ntau lawm, cov chaw tsim khoom tau hloov pauv, thiab rov ua haujlwm tau zoo.
Tom qab kev soj ntsuam, nws tau pom tias lub ntsiab yog vim li cas cov castables muab los ntawm cov thawj castable chaw tsim tshuaj paus tsis ncav cuag lawv cov kev pab cuam lub neej yog hais tias lub zog ntawm nruab nrab kub (1093 degree) yog tsis txaus. Cov ntaub ntawv txuas rau kev txiav txim kom meej meej qhia tias kev siv kub ntawm cov castables yog 1100 degree.
Muab piv rau ob qho khoom siv tau ua tiav, muaj qhov sib txawv ntawm cov ntom ntom ntom thiab lub zog compressive. Cov kev ntxhib los mos ntawm cov castable refractory ntawm tus thawj castable chaw tsim tshuaj paus yog xoob, thaum lub aggregate kev ntxhib los mos ntawm hloov chaw tsim tshuaj paus yog ntom, thiab cov mis kuj txawv, yog li cov nyhuv siv kuj pom tseeb txawv.
