Abstract
The invention relates to computer-implemented charging of a blast furnace equipped with an automated top-charging installation and stockhouse for batchwise charging. It proposes: obtaining a nominal charge dataset reflecting a nominal blast furnace charge and comprising plural charge material records, each charge material record comprising a material type and an associated nominal charge quantity; generating a graphical user interface comprising batch data fields for entering and displaying plural batch datasets for pre-configuring batches, each batch dataset comprising at least one batching record, each batching record comprising a material type and an associated batching proportion. According to the invention, the batching proportion associated to a material type in a batching record is used for predefining a ratio between the material quantity that is to be contained in a batch and the nominal charge quantity. Further according to the invention, the method comprises computing, for the respective material type of each batching record, based on the batching proportion and the nominal charge quantity associated to the respective material type, an associated batching quantity which …
