Features: High temperature performance, strong erosion resistance,thermal shock stability is excellent, is a non-ferrous smelting alkaline refractory one of the refractory. Mainly used in non-ferrous metallurgical industry, a wide range of kiln furnace temperature fluctuations in the larger area, more resistant than high alumina brick erosion, thermal shock stability than magnesium chrome brick better; can also be used for the bottom of the pool,furnace wall and rotary kiln Lining parts, in the nickel-iron rotary kiln, compared to traditional refractory high temperature performance and erosion resistance is more excellent,the service life of up to 1 year.
