Problems solved by technology
[0005] Aiming at the deficiencies of the prior art, the present invention provides an intelligent multifunctional furnace wall gun retractable device, which solves the problem that the furnace wall guns used in the current steelmaking electric furnace are generally fixedly installed on the furnace wall of the electric furnace, and the position cannot be changed, and the gun position cannot be adjusted. The problem to be changed. In addition, the furnace wall gun is installed above the upper part of the highest position of the molten steel level by more than 350mm. When the molten steel level is low, the furnace wall gun is farther away from the molten steel surface, and the utilization rate of the furnace wall gun injection medium is low. question

The invention belongs to the technical field of multifunctional furnace wall guns, and particularly relates to an intelligent multifunctional furnace wall gun stretching-retracting device. The devicecomprises a bottom plate, a stand column is arranged at an upper end of the bottom plate, a stand column hole is formed in the stand column, a first shaft is arranged on an inner surface wall of the stand column hole, a first cross arm hole is formed in the first shaft, and a pitching hydraulic mounting base is arranged on one side of the stand column. By additionally arranging a furnace wall gunmoving trolley, a moving hydraulic cylinder and a chain conveying device, a moving proportion of stretching and retracting of the moving hydraulic cylinder to the moving distance of the multifunctional furnace wall gun can be achieved, and the flexibility of the stretching-retracting device is improved; by additionally arranging the stand column hole, the first shaft, the first cross arm hole, thepitching hydraulic cylinder, a pitching hydraulic cylinder mounting hole, a second shaft and a second cross arm hole, the multifunctional furnace wall gun can pitch, so that the distance between a molten steel level and the multifunctional furnace wall gun is not changed, and an utilization rate of a blowing medium of the multifunctional furnace wall gun is increased.
Description
technical field [0001] The invention relates to the technical field of an intelligent multifunctional furnace wall gun injection control module, in particular to an intelligent multifunctional furnace wall gun telescopic device. Background technique [0002] Furnace wall gun is one of the main process equipment in steelmaking. Its performance characteristics directly affect the smelting effect and blowing time, thereby affecting the quality and output of steel; during the blowing process, the furnace wall gun not only has to withstand fire The heat radiation in the high temperature zone of about 2500 ℃ also bears the intense erosion of steel and slag, and the working conditions are very harsh. Therefore, the furnace wall gun must have a solid metal structure and a strong water cooling system to ensure that it can withstand high temperature, erosion resistance and vibration resistance; The scope of application has expanded to the fields of electric arc furnace and ladle refi...
