    摘要： Controlling circumferential variability in a blast furnace may include generating a predictive model that sets up a relationship between a standard deviation of a selected state variable, state variables and one or more control variables in blast furnace operation for predicting the standard deviation. A number of circumferential sections of the blast furnace is defined, and the predictive model associated with the selected state variable for each of the circumferential sections is trained based on process data of the blast furnace. A plurality trained predictive models is generated associated with different circumferential sections and different selected state variables. One or more future control variable set points that minimize a sum of the plurality of predictive models, is determined. One or more future control variable set points is transmitted to a control system to control the blast furnace operation.

    摘要： A method of constructing a shaft furnace is provided, as well as an assembly and a fixation structure therefor. The method comprises the steps of providing on a first position a furnace segment comprising a ring wall extending along a central axis, and transporting the segment to a second position and operably attaching the segment there to one or more further blast furnace portions. The method further comprises that during said transporting the segment to the second position the segment comprises at least one fixation structure comprising a plurality of tensioned tensile members attached to the wall determining a shape of the segment.

    摘要： Provided is a device for producing partially reduced iron, with which partially reduced iron having a prescribed reduction ratio can be produced efficiently. The present invention is equipped with: CO sensors that detect the carbon monoxide concentration in an exhaust gas; an O2 sensor that detects the oxygen concentration in an exhaust gas; an exhaust gas circulation device that adjusts the circulating amount of the exhaust gas supplied to a reduction furnace main body, and an air feed device that adjusts the amount of air that being fed; and a control device that controls these devices. The control devices on the basis of the carbon monoxide concentration in the exhaust gas as detected by the CO sensor and the oxygen concentration in the exhaust gas as detected by the O2 sensor.

    摘要： A pressure relief valve system has a fluid outlet (1) from a pressure vessel; a flexible expansion piece (4) at an end of the fluid outlet remote from the pressure vessel; a primary pressure relief valve has a valve seat and a valve lid (7). The valve seat has a flange (5) mounted on the expansion piece and the valve lid forms a valve seal with the flange. A fluid off-take (13) is connected to the fluid outlet (1) and a secondary pressure relief valve (11) receives fluid from the fluid off-take. The secondary pressure relief valve has an outlet (12) coupled to a valve opening actuator (15), whereby passage of fluid through the secondary pressure relief valve (11) causes the opening actuator to operate to open the valve lid (7).

    摘要： In a method and a device for operating a smelting reduction process, at least part of an export gas from a blast furnace or a reduction unit is thermally utilized in a gas turbine and the exhaust gas of this gas turbine is used in a waste heat steam generator to generate steam. The remaining part of the export gas is fed to a CO2 separation apparatus, the tail gas thereby obtained being fed to a waste heat steam generator and burned for additional steam generation. The combustible components of the tail gas are sent for thermal utilization in a steam generator, so that the overall energy balance of the thermal use of the export gas is improved. In addition, a further part of the export gas is qualitatively improved by the CO2 separation apparatus, so as to generate a high-quality reduction gas which can be supplied for metallurgical use.
