Technical Field
The invention provides a metallurgical node temperature monitoring method and system, and belongs to the technical field of metallurgical temperature monitoring.
Background
Metallurgy is a subject and engineering area of technology that relates to the production, refining, processing and application of metals and metal alloys. In the background of metallurgy, several key areas are involved. In metallurgical processes, the type of furnace employed depends on the type of ore or raw material to be treated and the desired end product. Different furnace bodies have different advantages and disadvantages, so that a plurality of different types of furnace bodies can be used in the metallurgical process. Open furnace vessels are a common metallurgical equipment for melting metals or metal alloys. Unlike closed furnaces, open furnaces are typically open at the top or sides, allowing the metal to come into direct contact with the outside during heating. This type of furnace is widely used in primary smelting of iron ore, refining of molten steel, casting and other metal processes. However, the open furnace body is communicated with the external environment due to the temperature, and when the metal melt is not safely filled in the open furnace body, the temperature conduction is generated due to the contact of the furnace wall and the metal melt, and meanwhile, the open furnace body is communicated with the external environment, so that the temperature threshold value of the metallurgical node cannot be accurately determined.
