Hauv kev tsim kho thiab siv cov txiv qaub teb kilns,refractory castableteeb meem tau muab faib ua ob pawg: ib qho yog qhov teeb meem ntawm castable solidification ceev thaum lub sij hawm tsim kho; lwm yam yog castable zoo teeb meem uas tshwm sim thaum lub sij hawm ntau lawm txheej txheem.
(1) Thaum tsim lub 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, uas ua rau rework ntawm 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. Cement tau resuppled, 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 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, txuag lub sijhawm rau kev thauj mus los thiab ua tiav cov txiaj ntsig pom tseeb.
(2) Thaum lub sij hawm tsim cov txheej txheem, cov castables ntawm lub hloov chutes ntawm plaub lub teb kiln tau hnav thiab poob tawm ob peb zaug. Qhov kub ntawm qhov qis ntawm qhov hloov chutes maj mam nce, nce mus txog 600 degree, thiab sab nrauv steel phaj yog xim liab. Tom qab nres lub qhov cub, peb tau mus rau hauv qhov cub rau kev soj ntsuam thiab pom tias cov castables tau hnav tawm qhov pits, nthuav tawm cov hlau phaj, thiab cov anchors kuj polished. Cov castables ntawm lub hloov chute poob tawm.
Cov castables nyob rau hauv no yog tag nrho cov qis-cement castables nrog cov ntsiab lus alumina ntawm 70%, thiab yav dhau los 400t·d-1 thiab 600t·d-1 kilns kuj siv castables nrog tib lub cev thiab tshuaj ntsuas 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 kho mob mus rau qhov chaw kho mob ntau zaus, tab sis tsis pom muaj kev daws teeb meem zoo dua. Txhawm rau kom tsis txhob cuam tshuam cov kev xav tau ntawm Anshan Hlau thiab Hlau, qhov project department ntawm Tuam Tshoj Metallurgical Coking Refractory Engineering Technology Co., Ltd. hloov cov chaw tsim khoom, thiab cov nyhuv zoo tom qab rov ua dua.
Tom qab kev soj ntsuam, lub ntsiab yog vim li cas cov refractory 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 qhia tau hais tias qhov 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 castables ntawm tus thawj castable chaw tsim tshuaj paus yog xoob, thaum lub aggregate kev ntxhib los mos ntawm cov hloov chaw tsim tshuaj paus yog ntom, thiab cov mis kuj txawv, yog li cov nyhuv siv kuj pom tseeb txawv.
