剛玉澆注料是根據(jù)固態(tài)流體理論，結(jié)合耐火材料的應(yīng)用特點而開發(fā)的高科技產(chǎn)品，國內(nèi)首創(chuàng)。剛玉自流料可借助自身重力作用，不經(jīng)振動而脫氣、流平，從而實現(xiàn)致密化。
剛玉澆注料具有如下優(yōu)點：流動性好、凝固時間合理、省工省力、快捷方便、強(qiáng)度高、壽命長、有較好的保溫性能、耐高溫、抗震穩(wěn)定性良好、抗侵蝕和耐沖刷。剛玉質(zhì)澆注料適合于鋼包包底及座磚周圍、電爐頂填縫。
Corundum castable is a high-tech product developed according to the theory of solid fluid and the application characteristics of refractories, which is the first in China. The corundum self flowing material can be degassed and leveled by its own gravity without vibration, so as to realize densification.
Corundum castable has the following advantages: good fluidity, reasonable solidification time, labor-saving, fast and convenient, high strength, long service life, good thermal insulation performance, high temperature resistance, good seismic stability, corrosion resistance and erosion resistance. Corundum castable is suitable for joint filling at the bottom of ladle, around the block and top of electric furnace.
