Converter furnace lining thickness radar intelligent detection system

Abstract

The invention discloses a converter furnace lining thickness radar intelligent detection system. The system comprises a lifting mechanism, a radar device and a controller. The lifting mechanism and the radar device are connected with the controller. The lifting mechanism is connected with the radar device. The lifting mechanism lifts or lowers the radar device under the control of the controller.The radar device upwardly and downwardly moves in the detected converter furnace under driving of the lifting mechanism and transmits electromagnetic waves to the surface of the detected converter furnace lining. The controller processes the data acquired by the radar device. According to the converter furnace lining thickness radar intelligent detection system, converter furnace lining thicknessdetection is performed by using the radar device so that the system has the characteristics of high automation level and short measurement time and can realize converter furnace lining thickness measurement and provide the more accurate lining erosion information.

Description

technical field [0001] The invention relates to the technical field of metallurgy and steelmaking, in particular to a radar intelligent detection system for converter lining thickness. Background technique [0002] Converter steelmaking is an important steelmaking method in industrial production. During the steelmaking process, the converter lining is in direct contact with molten steel, slag, and furnace gas, and is eroded by chemical, physical, and mechanical effects for a long time. Thickness, which in turn makes the converter a safety hazard, therefore, the maintenance and repair of the lining is very important. At present, steel mills at home and abroad generally adopt the technology of slag splashing to protect the furnace. To grasp the best timing of slag splashing, it is necessary to grasp the shape and thickness of the furnace lining. Therefore, detection of converter lining thickness is of great significance to the steelmaking industry. [0003] At present, domes...

Problems solved by technology

[0003] At present, domestic iron and steel enterprises measure the thickness of converter lining by laser thickness measurement method. This method needs to find a location, and the measurement takes a long time (at least 15 minutes), which is easy to affect the production rhythm of the converter. It is impossible to measure the lining thickness of each furnace At the same time, the cost of the laser thickness measurement system is relatively high. Considering the production rhythm control and cost control of various iron and steel enterprises, the application rate of the laser thickness measurement method is low. Timely and comprehensive acquisition of furnace lining erosion information prevents timely maintenance of the converter lining, resulting in potential safety hazards in the converter, reduced converter service life, prolonged smelting time of the converter, and the phenomenon that the final composition exceeds the specified composition.
