SUMMARY:Experiences with precast blocks made of steel fibre reinforced fused silica materials in comparison to the cordierite castable used up to now
DESCRIPTION:The requirements for the door plug building blocks of the Schwelgern coking plant are particularly challenging due to the door height of 8.43 meters. In order to ensure the tightness of the doors, the durability of the insulating bricks of the coke oven doors, the so-called door plug components, is essential for a safe oven door repair process.
In the course of the continuous improvement of processes (CIP), the proven door plugs modules of the Schwelgern coking plant were further improved. The focus of further improvement was on reducing the expansion coefficient of the components in order to achieve a longer service life and less susceptibility to cracking.
Initial tests in the laboratory and in practice showed positive results and confirmed the theoretical approach. In addition to the newly developed material grade, the prefabricated components were reinforced with a special steel fiber to achieve another positive effect.
The operational experience of the last six years, which is shown in this presentation, shows that the newly developed components outperform the conventional parts in terms of service life. The consumption of door plug modules could be reduced significantly.
