Problems solved by technology
When a failure occurs, the furnace pressure fluctuates greatly, and the furnace pressure deviates from 5 mm of water column, and the unit consumption of the furnace rises by more than 12%. This year alone, about 40,000 yuan of energy is wasted
In addition, the instability of the furnace pressure causes the oxidation of the billet in the furnace, and the loss cannot be calculated

The invention discloses a driving mechanism of a billet heating furnace flue damper. The driving mechanism includes a speed reducer (2), and the output shaft of a motor (1) is in connection with the input shaft of the speed reducer (2), a speed reducer output shaft (3) on the speed reducer (2) is provided with an output shaft rocking bar (4) that is perpendicular to the axis of the speed reducer output shaft (3) and is in fastened connection with the speed reducer output shaft (3). The rotating shaft of the flue damper (9) is equipped with a flue damper rocking bar (7) that is perpendicular to the axis of the rotating shaft of the flue damper and is in fastened connection with the rotating shaft of the flue damper. The speed reducer output shaft (3) is in parallel with the rotating shaft of the flue damper (9), and the flue damper rocking bar (7) is hinged to the output shaft rocking bar (4) through a connection swing rod (6), thus forming a paralleled double-crank mechanism. In addition, the invention also provides a control method of the driving mechanism. With the technical scheme of the method, the flue damper can operate stably and reliably with good actual use effect. Meanwhile, the failure rate is reduced, the work output of workers is also reduced, and the product quality is improved.
Description
technical field [0001] The invention belongs to the technical field of production equipment in the metallurgical industry, and relates to the equipment control technology of a steel billet heating furnace. More specifically, the invention relates to a driving mechanism for a flue shutter of a steel billet heating furnace. In addition, the present invention also relates to a control method of the driving mechanism. Background technique [0002] For the billet heating furnace, in order to discharge the exhaust gas burned in the furnace and maintain a certain pressure (usually a slight positive pressure) in the furnace, a flue gate (ie, a valve) is installed in the flue. By adjusting the opening of the flue damper to control the amount of exhaust smoke, and then control the furnace pressure. [0003] At present, for the flue gate of the heating furnace, it is generally driven by a pneumatic actuator, and the valve positioner is used to control the opening of the valve; there a...
