Summary

The cement industry has since long recognized many factors affecting the lining life of rotary kilns. However, as the rotary kilns increase in diameter, the combined mechanical and thermal stresses make it necessary to develop bricks with better elasticity. This paper reports on a magnesia-chrome brick developed recently by paying attention to its modulus of elasticity. Laboratory tests, such as for thermal shock resistance, coating formation, refractoriness under load, and mechanical properties are also reported. Experiences in the field are examined.
