Khoom piav qhia
High temp bricks alumina cib yog ib hom ntawm nruab nrab qib hluav taws cib ntawm cov khoom stereotyped ntawm cov ntaub ntawv refractory. Nws belongs rau nruab nrab cov ntaub ntawv refractory thiab yog siv nyob rau hauv ob sab phlu ntawm industrial kilns.
Qhov zoo ntawm high temp bricks alumina bricks yog txawv los ntawm txawv txhuas cov ntsiab lus thiab lub cev ntom ntom, thiab hluav taws kub tsis kam ntawm siab alumina bricks ncav cuag 1790 degree. Nws tseem tuaj yeem ntxiv cov khoom xyaw sib txawv ntawm cov khoom siv raw los tsim cov khoom sib txawv thiab cov khoom sib xyaw refractory cib.
Daim ntawv thov:
Kev siv cov aluminium bricks siab yog tsuas yog siv rau phab ntsa ironmaking blast furnace, kub moj tej tawg rauv, cua sov rauv saum toj, moj tej tawg rauv, reverberatory rauv, txhua yam hauv ob sab phlu. Tsis tas li ntawd, high-aluminium bricks kuj yog siv nyob rau hauv style furnace heat storage grid bricks, plug heads for pouring management systems, and water position bricks. Txawm li cas los xij, tus nqi siab ntawm aluminium bricks yog siab dua li cov av nplaum cib, yog li tsis tas yuav tsum siv cov aluminium cib siab yog cov av nplaum cib tuaj yeem ua tau raws li qhov yuav tsum tau ua hauv zos.
