| Abstract Scope |
Linings of rotary kilns, e.g. in the cement industry, consist frequently of basic refractory materials. Such refractory linings are based mainly on magnesia because of it’s chemical behavior in the industrial process used. Unfortunately magnesia shows a high linear thermal expansion and as effect a low flexibility and thermal shock resistance. To influence the flexibility-/thermal shock resistance-behavior positively, the use of an additive, improving these properties is needed. Used additives are normally minerals of the spinel group, containing quite high levels of Al2O3 and Fe2O3. With increasing amount, a positive effect on flexibility, but on the other hand a negative influence on refractoriness can be detected. The new, innovative Spinosphere Technology is a significant step forward in development of basic rotary kiln bricks, allowing the production of MgO-based refractory bricks that show both, a high flexibility and high refractoriness. |
