Method and apparatus for casting of the annular gap between the charging hole lid and filling hole frame to a coke oven

摘要

The present invention relates to a method and apparatus for casting of the annular gap between the charging hole lid and filling hole frame to a coke oven in air with the use of a thermosetting sealing material, which consists of a stirred vessel (4) and drawn off by a discharge line (6) positioned at the charging hole lid a distributing channel (7) is fed to. In front of the distributor channel (7) is a shut-off valve (8) in the discharge line is disposed, with which the inlet to the distributor channel (7) is opened and closed. According to the invention, the container interior of the stirred vessel (4) with an inert gas which the sealing material (12) within the stirring vessel (4) as well as the subsequent discharge line (6) to the shut-off valve (8) under pressure. The sealing compound flows under the pressure of the inert gas by opening the shut-off valve (8) into the distributor channel (7) from. The end of the casting process, the shut-off valve (8) is closed and the distributor channel (7) is rinsed with water.
