INVESTIGATION OF THE COKE NETWORK AND COHESIVE ZONE BY MUON TOMOGRAPHY

摘要

Muon tomography for analyzing the density distribution in blast furnaces is introduced as a new measurement tool. The application at blast furnaces requires a special muon detector system. The characteristics of the system are determined by calibration measurements at a slab stack. At BF 2 of ArcelorMittal Bremen three different types of scans are performed in the area of the coke network and the cohesive zone. The density distributions display areas of different densities within the coke network which can give information about the situation inside the blast furnace, especially the position and the shape of the cohesive zone. This knowledge can be used to stabilize the cohesive zone and, thus, the whole process.
