Problems solved by technology
Manual identification and operation are sensitive to human error, and the ability of operators to process multi-source information is limited, often ignoring the influence of some variables
In a limited time, under great mental pressure, it is often difficult for operators to make effective decisions
The artificial adjustment method of the operator depends entirely on the operator's own experience, and it is difficult to ensure the timeliness and accuracy of decision-making
If there are accidents such as improper operation, neglect of detection, or equipment failure caused by irresistible natural factors, which will cause production interruption and other accidents, it will bring huge waste and loss to production.

Embodiment Construction
[0052] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0053] like image 3 As shown, the smelting process of the fused magnesium furnace mainly includes working conditions such as feeding, heating and melting, and exhaust. The heat generated by the arc melts the raw materials to obtain the final product. By setting different current setting values, the current control system tracks the changing setting values by adjusting the distance between the electrode and the molten pool, and adjusts the size of the arc to meet the energy required by different working conditions. In order to obtain higher economic benefits, it is necessary to maintain good operational performance and production safety in the production of fused magnesium.
[0054]The devices involved in the methods in the following embodiments include: an...

The invention provides a method for identifying and controlling abnormal working conditions of a fused magnesium furnace. The method includes: obtaining online data within a preset period in the working conditions of the fused magnesium furnace; using a similarity matching strategy to check whether the case information in the case library matches the online data; if it exists, providing the case information based on the matching case information The identification results of the current online data are used as the abnormal identification results of the current fused magnesium furnace working conditions; among them, the case library is case information of various abnormal working conditions established in advance based on the historical data of the fused magnesium furnace working conditions; If there is no matching case information in the case library, the Bayesian network inference model is used to analyze the online data to obtain the identification result, which is used as the abnormal identification result of the current fused magnesium furnace working condition. The above methods are of great significance for improving the comprehensive utilization rate of mineral resources, reducing energy consumption, reducing environmental pollution, and promoting safe production.
Description
technical field [0001] The invention belongs to computer technology, and in particular relates to a method for identifying abnormal working conditions of an electric fused magnesium furnace and a safety control method. Background technique [0002] Fused magnesium is an important refractory material, which has the following advantages: strong insulation, high melting point, strong oxidation resistance and compact structure, so it has been widely used in various industrial productions. The raw material of fused magnesium is magnesite. In most cases, the raw material grade is low and the mineral composition is complex and diverse. [0003] The smelting equipment used for fused magnesium is a three-phase fused magnesium furnace, and the current control system of the fused magnesium furnace tracks the current setting value under different working conditions to complete the smelting process. In practical applications, when the particle size, composition, melting point, etc. of r...
