The large amount of deformation of the tank body indicates that during the processing of the RH vacuum tank, the vacuum tank is in a process of continuous deformation. When the RH vacuum tank is processed more times, the gradual deformation of the tank body will cause gaps at the connection between the dipping tube and the circulation tube , in the process of processing molten steel, molten steel may easily leak from here, causing the tank body to wear steel

The invention discloses a method for effectively relieving deformation of a tank body of an RH vacuum tank. An adopted control method comprises the steps: a tank groove cooling air pipe is optimally improved; a pull bar is welded to a lower tank pot bottom; and a fire-resistant layer is additionally arranged on a splash board. When the number of treating times of the RH vacuum tank is large, the tank body gradually deforms, consequently a gap is generated in the junction of a dipping pipe and a circulating pipe, in the molten steel treating process, molten steel is extremely easily likely to leak from the gap to cause tank body steel penetrating, therefore, it is necessary to study the method for effectively relieving deformation of the tank body of the RH vacuum tank to effectively decrease the deformation amount of the tank body in the RH treating process, and thus steel penetrating caused by tank body deformation is eliminated.
Description
technical field [0001] The invention belongs to the field of RH steelmaking, and in particular relates to a method for effectively slowing down the deformation of an RH vacuum tank body. Background technique [0002] At this stage, judging from the deformation of the 210-ton RH vacuum tank, the deformation of the bottom of the bottom tank is serious, and the maximum deformation reaches 70mm (in the offline state). The large amount of deformation of the tank body indicates that during the processing of the RH vacuum tank, the vacuum tank is in a process of continuous deformation. When the RH vacuum tank is processed more times, the gradual deformation of the tank body will cause gaps at the connection between the dipping tube and the circulation tube , in the process of processing molten steel, molten steel may easily leak from here, causing the tank body to wear steel. Therefore, it is necessary to study a method to effectively slow down the deformation of the RH vacuum tan...
