Alumina cib feem ntau xa mus rau Alumina silicate cib, nrog Al2O3 thiab SiO2 cov ntsiab lus ua cov ntsiab lus tseem ceeb, thiab Fe2O3, Na2O, K2O, TiO2 ua impurities.
Nrog rau cov ntsiab lus sib txawv Al2O3, alumina cib suav nrog cov av nplaum refractory (Al2O3 cov ntsiab lus hauv 48% nrog Kaolin li raw khoom), siab alumina cib (Al2O3 cov ntsiab lus 48% -85%, nrog bauxite li raw khoom), tuab mullite cib, silimanite cib, corundum cib nrog raw cov ntsiab lus (Al2O3) thiab lwm yam.
Technical data of alumina bricks generally include chemical composition(content of Al2O3 and Fe2O3), bulk density, apparent porosity, cold crushing strength, permanent liner change and refractoriness under load 0.2 MPa.
Nrog siab dua Al2O3 cov ntsiab lus, cib nrog

Kev ua haujlwm ruaj khov dua
Tab sis thermal poob siab tsis kam ntawm corumdum cib tsis muaj zog dua li cov alumina cib siab thiab mullite cib, yog li cov cib uas muaj Al2O3 ntau dua cov ntsiab lus feem ntau yog siv los ua haujlwm hauv ob sab phlu, kilns thiab boiler nrog qhov kub thiab txias.
Kev tsim cov txheej txheem: Sib tsoo ntawm cov khoom siv raw --- Batching-- Shaping nrog hydraulic xovxwm-- firing hauv qhov kilns --- tshuaj xyuas thiab ntim hauv warehouse
Cov yam ntxwv tseem ceeb rau Refractory Clay Bricks
● Zoo thermal shock thiab spa lling kuj
● Zoo tiv thaiv corrosion thiab corrosion
● Zoo ntim ruaj khov ntawm qhov kub thiab txias
● Lub zog txhua yam
Daim ntawv thov tseem ceeb rau Refractory Clay Bricks yog teev hauv qab no:
● Kev tsim kho rauv
● Blast furnace∕Kub tawg qhov cub
● Steel foundries
● Rauv hauv kev lag luam hlau nonferrous
● Coke qhov cub thiab Gas rauv
● iav kev lag luam
● Kev lag luam cement
● Kev nyab xeeb hauv ob sab phlu
● Thaub qab txheej ntawm boiler
