Refractory cib yog cov khoom siv kub-resistant, thiab nws qhov tshwj xeeb kub-resistant kev ua tau zoo nyob ntawm nws cov muaj pes tsawg leeg thiab kev tsim khoom. Feem ntau cov cib refractory tuaj yeem tiv taus qhov kub siab tshaj 1000 degree, tab sis qhov kub tsis kam ntawm refractory firebricks nrog cov khoom sib txawv thiab cov txheej txheem tsim khoom yuav txawv.
Refractory hluav taws cib feem ntau yog ua los ntawm cov khoom siv refractory. Feem ntau hais lus, cov ntaub ntawv no suav nrog high-alumina alumina, aluminium silicate, magnesium silicate, thiab lwm yam. Cov ntaub ntawv no muaj cov ntsiab lus melting siab thiab ruaj khov ntawm qhov kub thiab txias yam tsis muaj melting lossis softening yooj yim. Nyob rau tib lub sij hawm, refractory bricks kuj muaj thermal conductivity, uas yuav pab kom disperse thiab ua cua sov thiab tiv thaiv lub zos overheating. Refractory firebricks feem ntau yog ua los ntawm cov khoom siv porous ceramic, cov qauv uas khaws cov cua sov thiab pab tiv thaiv kev kub nyhiab. Qhov no kuj pab txhim kho nws qhov kub thiab txias.
Lub refractory kub tsis kam ntawm ntau hom refractory bricks yog raws li nram no:
Lub teeb yuag hluav taws xob rwb thaiv tsev cib (hluav taws kub- av nkos cib): Qhov ntsuas kub tsis kam tiv thaiv feem ntau yog nyob ib puag ncig 1,000 degrees Celsius.
Txheem refractory hluav taws cib: Feem ntau tuaj yeem tiv taus qhov kub ntawm 1,300 degrees Celsius mus rau 1,400 degrees Celsius.
Refractory High Alumina Bricks: Hom refractory cib no tuaj yeem tiv taus qhov kub siab dua, feem ntau ntawm 1,500 degrees Celsius thiab 1,600 degrees Celsius.
Proton Graphite Refractory Cib: Qhov no yog cov cib siab siab refractory uas tuaj yeem tiv taus qhov kub siab dua, ncav cuag 1,700 degrees Celsius mus rau 1,800 degrees Celsius.
Thov nco ntsoov tias cov no yog cov kev taw qhia dav dav thiab cov chaw tsim khoom sib txawv thiab cov khoom lag luam yuav muaj qhov sib txawv thiab kev ua tau zoo. Qhov kub tsis kam ntawm refractory hluav taws cib yuav cuam tshuam los ntawm kev siv ib puag ncig, siv cov xwm txheej (xws li kev thauj khoom, huab cua, thiab lwm yam) thiab siv sijhawm. Tib hom refractory cib tsim los ntawm cov tuam txhab sib txawv kuj tseem muaj qhov sib txawv ntawm qhov kub thiab txias. Yog li ntawd, thaum siv refractory bricks, nws yog ib qhov tsim nyog los xaiv cov refractory bricks tsim nyog raws li cov xwm txheej tshwj xeeb thiab nruj me ntsis raws li cov kev siv specifications kom muaj kev ruaj ntseg thiab durability.
