Modell zur Beschreibung der Trocknung von Feuerbetonen
Abstract
dc:descriptionThe accomplished investigations about the drying process of refractory concrete are of interest for the refractory industry, whose world-wide sold products are mainly used in the steel industry. In the recent years a considerable amount of refractory companies replaced their products with new technology: monolithic refractory materials - castables. The success of these materials is due to their numerous advantages. They have better insulation, the lining can be cast in a shorter period of time and the linings can be easily fit to different slopes. However, castables have to be dried at the customer´s premises. This drying process should under economical and environmental considerations be done as quickly as possible and too high vapour pressure should not occur. In order to improve the existing drying rules, prior measurements were undergone both, in the laboratory and in-situ. These measurements are very time-consuming and expensive. Additionally to various results in the past, the present doctorate contains numerical simulations where the most important mechanisms within the drying process of microporous, moisture containing refractory concretes are described. Beside the mass and energy transfer, adequate empirical equations to simulate the drying process are summarized. The developed model is tested by two different ultra low cement castables used as working linings of steel ladles and as safety linings of tundishes. The numerical results are compared with those obtained by prior experimental measurements.
