Investigation of 3D charging dissymmetries and influence on the blast furnace condition
Blast furnace performance strongly depends on a proper gas distribution control. The appropriate charging of materials in the blast furnace is thereby one of the most important determining control means. The project�s focus is on 3D information of dumped material. A highlight of the project was the development and application of a new radar technology for complete surface scan of the burden. This part of the work was carried out by MEFOS. This highly innovate 3D radar was successfully tested in the Dillingen full scale pilot plant. At TKS, the new radar installation at Schwelgern 1 revealed, in cooperation with stockrod measurements and also a newly installed infrared camera, 3D information of the BF surface condition. In Dillingen, full scale pilot plant trials for dissymmetry investigation of trajectory mass discharge were carried out. First filling trajectory measurements at No4 BF in Dillingen were found to be in accordance with pilot trials. Charging models (TKS and Dillingen) were extended to 3D calculation capability. Moreover, Dillingen performed a first neutral network calculation to investigate the influence of a dissymmetrical layer piling up on a working BF. CSM developed a method to change coke charging (both in position and amount) in order to get a target central temperature using both model calculations and 3D above burden temperature measurements of No 2 BF in Piombino.
