And also point out the relation between refractory service life and masonry &firing. As the adjustment of nation industry policy, large dry-process rotary kiln will replace a multitude of shaft kiln and small type rotary kiln, thus there will be less demand for traditional refractory materials and more need for high quality refractory.
C as silica bricks display poor thermal shock resistance at such low temperatures. Alternatively silica checker bricks can be used can be used in high temperature zone, high alumina bricks in the middle temperature range and hard fired fireclay bricks and other high strength bricks at the bottom checker level.
