Abstract

Uncontrolled pushing force can lead to severe degradationof coke oven walls. To measure the pushing force a torquesensor can easily be installed on the driving shaft of thepushing machine.
The pushing curve shows a typical first peak whichcorresponds to the end of the coke cake compression phaseand the beginning of the coke cake movement. Generallyafter this peak the pushing force sharply decreases as cokemoves, coke weight decreases and oven taper prevents fromwall friction.
The first peak is related to the coke cake properties.
Pushing curves may show a progressive increase of pushingforce or further peaks depending on the pushing machineand the general condition of the oven.
Safe limit of pushing force first peak is around 1.5 times thecoke weight.
