  • Patent number: 9031704
    Abstract: 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.

  • Patent number: 8666557

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.

  • Patent number: 8088327
    Abstract: A rotary charging device for a shaft furnace commonly comprises a rotary distribution configured to distribute charge material on a charging surface in the shaft furnace. A rotatable structure supports the rotary distribution means and a stationary support rotatably supports the rotatable structure. According to the invention, the charging device is equipped with an inductive coupling device including a stationary inductor fixed to the stationary support and a rotary inductor fixed to the rotatable structure. The stationary inductor and the rotary inductor are separated by a radial gap and configured as rotary transformer for achieving contact-less electric energy transfer from the stationary support to the rotatable structure by means of magnetic coupling through the radial gap for powering an electric load arranged on the rotatable structure and connected to said rotary inductor.

  • Patent number: 6988857
    Abstract: A device for monitoring the mass flow of a particulate solids flow in a pneumatic pipeline includes a measuring chamber and an impact body. Through an inlet connection the particulate solids flow is blown as a compact solid/gas jet onto the impact body, so as to impact thereon with substantially its whole cross-section. An acoustic transducer is associated with the impact body for sensing structure-born acoustic waves, which are generated by the compact solid/gas jet impacting onto the impact body, and transforming them into an output signal. Signal processing process the output signal so as to derive a value that is representative of the mass flow rate of the particulate solids flow.

  • Patent number: 5166589
    Abstract: A probe includes a probe foot which is suspended on a cable or a chain attached to a winding drum mounted in a sealed casing above the furnace and which communicates with the interior of the latter via a vertical sleeve passing through the upper wall of the furnace, an electric motor associated with a reducer for actuating the winding drum, and a device for detecting the unwinding and winding up of the winding drum in order to control the speed and torque of the motor. The motor is a servomotor, the speed and torque of which are controlled automatically as a function of the detection device by comparison of the actual speed of the motor with data of desired values dependent on the position of the probe foot.
