  DDR-Unet: A High-Accuracy and Efficient Ore Image …

  This article presents deformable dense residual Unet (DDR-Unet), a high-accuracy and efficient method for ore image segmentation (OIS). OIS is a crucial step in measuring ore particle size distribution (PSD), but it faces challenges due to variations in particle sizes, shapes, overlaps, and powder interference. DDR-Unet improves U-Net in three aspects: …

  Sulphur removal in ironmaking and oxygen steelmaking

  2017322 · The main source of sulphur in the BF-BOF steelmaking process comes from coke. Even though roughly 40% of the sulphur in coal is removed in the coking process, typical sulphur levels in coke remain around 0.5%. Iron ore contains typically 0.01% sulphur and is only a minor source of sulphur in the steelmaking process 2, 8.
