Refractory cement yog yooj yim heev rau siv, tom qab ntxiv dej sib koom ua ke tuaj yeem muaj zog, feem ntau tsis tas yuav ntxiv cov khoom sib txuas, tuaj yeem siv rau cementing txhua yam refractory aggregates xws li corundum, calcined siab alumina bauxite, molybdenite, gangue, nthuav perlite, thiab lwm yam, tov nrog refractory mortar lossis pob zeb.
Yog tias tsuas yog siv cov cement refractory, ntau qhov tawg yuav tshwm sim tom qab kub kub.
Refractory cement yog txawv ntawm refractory av, tsis txhob sib tov refractory av thiab refractory cement tag nrho txoj kev mus rau refractory kev tsim kho, ib yam li cov av koom nyob rau hauv cov cement, yog li tsis zoo, solidification tsis muaj zog.
Cov cement refractory tshiab yuav tsum tau ci tom qab 72 teev. Nyob rau hauv qhov chaw ntawm qhov cua tsis zoo, noo noo tsis tuaj yeem tshem tawm tau yooj yim, lub sij hawm txuag hluav taws xob yuav tsum tau ncua ntev. Chav tsev kub ntawm 350 degrees theem, yuav tsum tau ci maj mam, txwv tsis pub nws yuav ua rau daim ntawv tawg. Yog tias tseem muaj kev tshuaj xyuas ntawm chav dej tom qab 350 degrees kev txuag hluav taws xob, txhawm rau tiv thaiv qhov tshwm sim sai sai, yuav tsum ua kom qeeb ntawm cov cua sov.
Thaum ci nrog ntoo, kev sib cuag ncaj qha nrog cov nplaim hluav taws feem ntau yog tsim los ntawm cov cua kub ceev heev, yuav tsum tau tiv thaiv. Thaum ci nrog cov roj hnyav, ceev faj tsis txhob tsuag cov roj hnyav rau ntawm lub hauv ob sab phlu kom tiv thaiv cov ntawv tawg. Cov cua txias ntawm cov ntaub ntawv refractory cement yuav tsum tau qeeb, kom tsis txhob yuam kev cua.
