SUMMARY:The use of sole heated oven for the technical support of Schwelgern coke plant 
DESCRIPTION:thyssenkrupp Steel Europe successfully commissioned their pilot oven laboratory employing both a 10-kg carbonization retort and a 60-kg movable wall oven between the years 2014 and 2016. The installed facilities produce and deliver important timely information to coke plant operators who can profit from captive analysis results of internal gas pressure, wall pressure, and coke qualities obtained from actual coal blends and individual coals. 
  
Sufficient shrinkage of the coal charge in coke ovens is one of the most essential process conditions to ensure smooth oven pushing performance. As indirect findings on coal shrinkage behavior could only be derived from the results of the two pilot ovens, other considerations were reviewed. 
In view of the constantly changing conditions in the coal market coupled with the gradual ageing of coke ovens facing an elevated risk of refractory wear due to insufficient coal charge contraction control, the company decided to take another step towards securing their operational safety, prolonging the lifetime of the assets, and saving substantial resources in the maintenance budget. 
  
thyssenkrupp Steel Europe launched another major project in 2018 aiming at installing the sole heated oven as the only standardized tool for assessing coal shrinkage behavior when employing an internationally recognized test method. The company Hutni Projekt Frydek-Mistek was selected as the main contractor utilizing their long term experience with similar test facility installations, thus extending their previous successful co-operation with thyssenkrupp Steel Europe in the designing and commissioning of the 60-kg movable wall oven. 
  
The sole heated oven was put into operation in 2019. The objective of this paper is to outline the steps taken towards the successful commissioning and the resulting technical support to thyssenkrupp Steel Europe’s coke plant in Schwelgern.
