Kiln cib yog tsim los ntawm firing av nplaum raws li muaj pes tsawg leeg nyob rau hauv lub cub kom txog thaum nws yog ib nrab vitrified, thiab rau tshwj xeeb lub hom phiaj kuj yuav glazed. Refractory bricks feem ntau muaj 30-40% alumina thiab cov khoom siv raw feem ntau yog chamotte nrog lwm cov ntaub ntawv.
Yuav ua li cas hluav taws cib tsim?
Firebricks yog tsim los ntawm cov xovxwm qhuav, tawv- av nkos, mos-mud casting, thiab kub-nias txheej txheemsiv hauv kev tsim cov cib tsev. … Cov ntaub ntawv nyoos yog fused nyob rau hauv lub cub hluav taws xob ua raws li los ntawm kev ua cov yaj hauv cov pwm tshwj xeeb.
Refractory cib ua haujlwm li cas?
Ib refractory cib yog tsim feem ntau kom tiv taus qhov kub thiab txias, tab sis feem ntau yuav muaj cov thermal conductivity tsawg dua rau kev siv hluav taws xob ntau dua.… Hauv lwm qhov, qhov xwm txheej hnyav dua, xws li hauv qhov cub hluav taws xob lossis hluav taws xob hluav taws xob, cov cib ntxeem tau ntau dua, feem ntau hu ua "kiln cib", yog qhov kev xaiv zoo dua.
Cov tshuaj twg siv los ua cov cib refractory?
oxides ntawm txhuas (alumina), silicon (silica) thiab magnesium (magnesia)yog cov khoom tseem ceeb tshaj plaws siv hauv kev tsim cov refractories. Lwm oxide feem ntau pom nyob rau hauv refractories yog oxide ntawm calcium (txiv qaub). Cov av nplaum hluav taws kuj tau siv dav hauv kev tsim cov refractories.
Vim li cas firebrick thiaj kim?
Cov cib no muaj siab alumina cov ntsiab lus, tau kub heev (1500F thiab siab dua) thiab tsim los rau kev siv hluav taws kub tsis tu ncua, xws li cov cub tawg. Lawv kim heev, thiab yuav kub dhau rau qee qhov ntawm koj qhov cub siv, xws li ci ci thiab ci.
