Txoj kev sintering yog ua ntej sinter ib co raw cov ntaub ntawv rau hauv clinker, crushed thiab tshuaj ntsuam lawv, ces sib tov nrog raw cov ntaub ntawv nyob rau hauv ib tug tej yam kev faib ua feem, thiab ces mus los ntawm shaping, ziab thiab tua. Lub hom phiaj ntawm pre-burning cov ntaub ntawv raw yog kom hlawv tawm cov dej noo, organic impurities, thiab gases tshwm sim los ntawm decomposition ntawm sulfates, thiaj li yuav txo tau lub firing shrinkage ntawm cov khoom thiab xyuas kom meej qhov tseeb ntawm qhov ntev ntawm cov khoom. Cov ntaub ntawv raw kuj tseem yuav tsum tau soj ntsuam tom qab crushing thiab sib tsoo, vim hais tias cov blanks tau muab qhab nia los ntawm cov hmoov sib txawv ntawm qhov ntau thiab tsawg los xyuas kom meej qhov ntim nruj tshaj plaws thiab tau txais lub cev ntom ntom.
Yuav kom homogenize lub Cheebtsam thiab hais ntawm ntau yam raw khoom thiab clinkers, lawv yuav tsum tau tov thiab binders yuav tsum tau ntxiv los txhim kho lub sib raug zoo lub zog ntawm lub blanks. Piv txwv li, binder av nplaum ntxiv rau aluminium silicate blanks, sulfite pulp pov tseg kua yog ntxiv rau magnesia blanks, txiv qaub mis ntxiv rau siliceous blanks, thiab lwm yam. Nyob ntawm seb cov dej noo ntawm qhov khoob, ib nrab qhuav molding (muaj kwv yees li 5% ya raws), yas molding (muaj kwv yees li 15% noo noo) thiab plam molding (muaj kwv yees li 40% ya raws) tuaj yeem siv. Nws yog ces qhuav thiab raug rho tawm haujlwm.
Cov txheej txheem melting thiab casting yuav tsum sib tov cov khoom raw thiab zoo sib tsoo, melting lawv ntawm kub kub, casting ncaj qha, thiab ces txias, crystallizing, thiab annealing lawv mus rau hauv cov khoom tiav. Xws li fused cam khwb cia mullite cib, corundum cib thiab fused magnesia cib, thiab lwm yam. Lawv lub cev ntsuab yog ntom, muaj zog txhua yam, siab kub structural zog, thiab zoo slag kuj, thiab lawv cov kev siv yog tas li nthuav.
Cov txheej txheem yaj tshuab yog ib txoj hauv kev uas cov khoom xyaw yog yaj thiab tom qab ntawd tshuab nrog cov cua kub siab los yog lub zog superheated kom tawg mus rau hauv fibers lossis hollow pob. Cov khoom siv tsuas yog siv los ua lub teeb yuag refractory thiab cov ntaub ntawv kub-insulating. Tsis tas li ntawd, nws tseem tuaj yeem ua rau cov khoom siv hmoov lossis granular amorphous refractory, uas yog cemented nrog binders xws li tar, asphalt, cement, phosphate, sulfate lossis chloride ntsev rau kev siv ib ntus, thiab tuaj yeem siv ncaj qha yam tsis muaj kev tsim thiab sintering.
