Spherical hinge sliding rod connecting device connecting disc for converter transformation

Abstract

The invention relates to a spherical hinge sliding rod connecting device connecting disc for converter transformation. The spherical hinge sliding rod connecting device connecting disc for converter transformation comprises an arc plate, a bearing ring, a spherical hinge bearing, a bearing shaft and multiple bearing ribs. The arc plate is tightly attached to and welded and fixed to the designatedposition of the outer wall of a shell of a converter through the edge, the bearing ring is welded and fixed to the arc plate and provided with a shaft hole, the spherical hinge bearing is arranged inthe shaft hole in a matched manner, the bearing shaft is matched in the inner ring of the spherical hinge bearing, and the bearing ribs are evenly distributed along the outer wall of the bearing ring.The bearing ribs, the outer wall of the bearing ring and the arc plate are welded and fixed into a whole, and point to the axis of the shaft hole, and the edge of the arc plate and the shaft hole aresymmetric about the middle axis. The connecting disc has a certain motion freedom degree, extra stress generated inside due to rotation and swing of the arc plate and the bearing ring in the converter and converter partial deforming can be avoided, whole reliability of the connecting disc is improved, the whole weight is reduced, the whole structural strength and welding strength can be ensured,and the whole reliability is improved.

Description

technical field [0001] The invention belongs to the field of steelmaking equipment, and in particular relates to a connecting plate of a spherical hinge sliding rod connecting device for converting a converter. Background technique [0002] The converter is the main steelmaking equipment. The converter connecting device is an important mechanical part connecting the converter shell and the support ring. Since the converter connecting device will bear heavy load and high temperature during the converter smelting process, the working conditions are extremely harsh. The design of the converter connecting device It directly affects the continuity of converter production with the processing quality. [0003] The ball joint slide rod connection device is a converter connection device with better application effect, so many old converter connection devices have been transformed into ball hinge slide rod connection devices. The converter shell is connected to the supporting ring, b...

[0003] The ball joint slide rod connection device is a converter connection device with better application effect, so many old converter connection devices have been transformed into ball hinge slide rod connection devices. The converter shell is connected to the supporting ring, but the installation of the connecting plate has the following problems: 1) The connecting plate is a stress-bearing part, which needs to ensure a certain structural strength. Additional stress will be generated inside the connection plate, affecting the reliability of the connection plate; 2) The furnace shell and support ring are not removed online, and the operating space is limited, which is not conducive to the welding of the connection plate, and the entire converter system is required for the reconstruction and installation of the lower connection device Turning up and down 180 degrees is not conducive to the welding of the welding connection plate. If the welding is inconvenient, it will affect the welding quality and bearing strength of the connection plate
