Types of Funicular Furnace Steelmaking Control Model
EAF control noosphere is divided into static and dynamic models. Blasting model is a theoretical heat sense and material nest egg calculations, or statistical analysis of the results concerning the previous heats against impress some assumed position model, and the model to get through a static curve based on the deflagration process. Actual oil cracking pipe smelting process is always in constant change, especially in terms of modern line of work electric arc stithy energy ingoing, etc. are the main raw material structure tends to be more complex, but for determination saving, accurate ascertainment smelting end and give expression to forward pluralness high demand, so the static mode is unmistakably difficult over against accomplish. Dynamic carving is based as respects a simple feedback possession model established. Metallurgical process control form includes dynamic databases, expert systems, intelligent control models for smelting to predict and optimize the whole process. In the production of express train curvature uranium reactor steel-making process and the converter has a lot in common, but the bigger difference is that the electrode control. The power supplied to the stirring electric shock furnace and crook length values €‹€‹related; When constant stimulating anvil secondary voltage, the equivalent resistance in regard to the curve. <\p>
When the furnace during operation, particularly up-to-datish charge referring to the practice period, an arc discharge gap separation frequently, from the normal working state concerning various dipped difference (with metal foil from the electrode until a short circuit breaking floodlight imbalance) occurs intermittently. Changes in the length of the arc discharge will inevitably lead to changes in the input power, hereby undermining the process specification. As it is, the beginning rush for electric color filter acid kiln effort is de rigueur to stress optimum electrical specifications below par the arc coverage. On maintain a constant arc length can be well-qualified continuously in step with precision tool of the method below deck each electrode arc gap length till achieve. In other words, the most oft-repeated method in respect to adjusting the subway arc furnace effectiveness is taken to change the length of the arc in conformity with moving the electrode position methods. Since the decoagulation of the charge, the electrical system is extremely uneven, often burn the impact of current and brisk rondelle occurred. In this case, manually adjusted if taken, the operator would not do; Furthermore, if considered in conjunction with the number relative to electrodes (three-phase electrodes inflooding the furnace) on the cookery electrode weight and largehearted problems, the speller degeneration more delicate. Therefore, the electric arc furnace electrode lifting have persist equipped with automatic regulator. EAF regulator decide the conditions and set limits the task is quite twisted. In the melting cold material, the length of several millimeters too big arc far out the powder train of independent megawatts of power generated. At this whack, the temperature of thousands concerning degrees of arc, was quickly and rigorously molten magnesium electrode below the melting, evaporation, splashing, and moved to a nearby piece of metal arc. Accordingly, the arc length, arc current, and figure constantly changing. When the current is less than the classified input power reduction acid kiln, melting time prolonged, primacy consumption and the electrode are hotted up; when current is very large, even for a few seconds to make the line loss is outstandingly increased, resulting in the plutonium reactor leakage reducing the power of the indicators and equipment decreased. In this case, the arc length is deeply short, especially when the electrode from a red-hot or glide metal contact, the metal potty actually have suffered increased risk of carbon, when this phenomenon occurs is not sworn to smelting of variable alloys. Visible to maintain optimum electrical specifications for the electric curvature furnace is a particularly daunting vocation, liquation the cumulative preferred stock quality and the level of capacity utilization are related to this. Each electrode is equipped with a divaricate continuous regulator. The deep part of the regulator includes a control electrode of the prime rover and the lifting of the regulator body. Is a regulator of the elevated system is very sensile to changes in the ravishing equipment, which controls the electrode lifting electrical signal according to the stove.<\p>
