A measuring unit was developed and installed in a pusher machine to examine wall deformations. The measuring process provides for a highly accurate quantitative assessment of coke oven deformations by using the measured chamber width. Also, there can be a satisfactory assessment of the state of deformation of the individual wall, after several measurements. The results of the measurements show clearly that each oven gives an unmistakable picture, comparable to a fingerprint. Oven wall deformation have a major impact on the extent and the development of the pushing force; in undeformed ovens the pushing forces are generally substantially lower. Furthermore it was shown, that in some cases considerable long-term changes can occur in the width of the chamber of +/- 5 mm, which lead to substantial pressure being exerted onto the brickwork, especially in the area of the head. The level of the pushing force is also influenced by this.
