Khoom piav qhia
Lc 60 castable nrog cov ntsiab lus cement tsawg. Lawv muaj cov yam ntxwv ntawm cov cement tsawg, cov ntsiab lus calcium tsawg, porosity tsawg, thiab muaj zog yaig tsis kam.
Qhov feem ntau siv qis-cement castable yog aluminium silicate, uas yog high-aluminium low-cement castable. Cov ntsiab lus cement ntawm high-aluminium low-cement castable yog 6%. Yog tias cov ntsiab lus cement yog 1%, nws yog cov cement castable ultra-low.
Daim ntawv thov ntawm lc 60 castable:
◆ Cement kiln
◆ Lub qhov cub cua sov
◆ Recirculating fluidized txaj boiler
◆ Kev lag luam tshuaj thiab kev tsim kho kev lag luam
◆ Tundish hauv ob sab phlu
Cov khoom zoo ntawm lc 60 castable yog raws li hauv qab no:
Tom qab cov cement castable qis yog cam khwb cia thiab molded, tsis muaj teeb meem noo noo thaum lub sijhawm kho. Hydration thaum lub sij hawm cua sov thiab ci txheej txheem yuav ua rau txo qis zog ntawm nruab nrab kub. Ntawm qhov tsis sib xws, raws li kev kho cua sov nce, lub zog kuj nce.
