    Abstract: The invention concerns cooling of the refractory lining in a smelting reduction vessel for producing hot metal. The vessel comprises an outer shell and an inner refractory lining for containing a bath of molten metal and a layer of slag above the bath. In order to create a voluminous turbulent slag layer for improving post-combustion heat transfer within the slag layer, the vessel further comprises at least one of the following devices: - a bottom gas blowing device for bubbling the bath of molten metal and the layer of slag; - a pneumatic injection device for injecting carbonaceous material into the layer of slag; or - an oxidant gas injection device for injecting an oxidant gas into the layer of slag. The refractory lining is dimensioned to define a capacity of at least twice the maximum volume of the bath of molten metal in order to contain the voluminous turbulent slag layer. A cooling installation is arranged in the zone of the turbulent slag layer with at least a major portion of the installation being located above the maximum level of the bath of molten metal for cooling the inner refractory lining in the zone of slag turbulence. According to the invention, the cooling installation comprises at least one row of copper slabs mounted onto openings provided in the outer shell and so as to be in thermo-conductive contact with the inner refractory lining in the zone of the turbulent slag layer and at least one row of spray cooling devices associated to the row of copper slabs for spraying liquid coolant onto the copper slabs through the openings in the shell.

    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. 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.
