Prediction and control of coke oven pushing performance is extremely important since it affects battery life and cost of operation. Experience at Inland Steel's coke batteries clearly indicates that, while many factors affect the ability to push coke, coal charge shrinkage is one of the main parameters determining pushing performance of the ovens. The magnitude of shrinkage required for a successful push of the coke cake depends on wall conditions and generally increases with oven deterioration due to age or poor operation. In order to fully understand the shrinkage phenomenon, a study of coal charge lateral contraction in the slot oven was initiated at Inland several years ago. In addition to the lateral contraction a number of other parameters were also monitored during trials. They included coal quality information and such operating parameters like bulk density, charge center temperature, wall pressure, etc. Moreover, coal charge vertical shrinkage measurements utilizing the procedure developed earlier were carried out, too.
