Pre-decomposition kiln mainly alkaline series of refractory bricks, high-alumina series of brick with high compressive strength and load softening temperature, better thermal shock stability.
A large number of pre-decomposition temperature for the higher decomposition furnace, rising flue feed chamber, rotary kiln feed port, kiln decomposition zone, kiln door, grate cooler inlet andSeries of high alumina bricks are common type, phosphate type, anti-stripping type and SIC impregnated type high alumina brick (silicon brick) used in the pre-decomposition kiln is the most anti-stripping type and SIC impregnated high aluminum type.
