摘要： In a charging process of a shaft furnace, in particular of a blast furnace, batches of charge material are typically discharged in cyclical sequence into the furnace from a top hopper using a flow control valve. A method and system is proposed for adjusting the flow rate of charge material in such a process. According to the invention, a respective set of plural valve settings is stored for each batch, each valve setting of a set being associated to a different stage in the discharge of the batch. The method and system are configured to discharge a given batch so that, at each stage in the discharge of the given batch, the flow control valve operates at a constant valve opening according to the valve setting associated to that stage and so that an actual average flow rate at which charge material is discharged is determined for that stage. Further according to the invention, the method and system are configured to correct the plural valve settings offline and in function of the actual average flow rate determined for the associated stage.

摘要： In a charging process of a shaft furnace, in particular of a blast furnace, batches of charge material are typically discharged in cyclical sequence into the furnace from a top hopper using a flow control valve. A method and system is proposed for adjusting the flow rate of charge material in such a process. Pre-determined valve characteristics for certain types of material are provided, each indicating the relation between flow rate and valve setting for one type of material. According to the invention, a specific valve characteristic is stored for each batch of charge material, each specific valve characteristic being bijectively associated to one batch and indicating the relation between flow rate and valve setting of the flow control valve specifically for the associated batch. In relation to discharging a given batch of the sequence the invention proposes: using the stored specific valve characteristic associated to the given batch for determining a requested valve setting corresponding to a flow rate setpoint and using the requested valve setting to operate the flow control valve; determining an actual average flow rate for the discharge of the given batch; correcting the stored specific valve characteristic associated to the given batch in case of a stipulated deviation between the flow rate setpoint and the actual average flow rate.

摘要： 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 the stockhouse is to provide in a batch as pre-configured by the batch dataset.
