A hyperbolic insert and its application in the process hole of the support ring of a box-type water-cooled converter
By using hyperbolic tubes in the converter support ring process holes, the arc-shaped transition rings are used to reduce stress concentration, which solves the problem of fatigue cracks caused by high temperature and alternating loads of the converter support ring process holes, which improves the structural bearing capacity and fatigue resistance and extends the service life.

AI Technical Summary
Technical Problem
In the prior art, the converter ring process holes produce fatigue cracks due to high temperature and alternating loads during steelmaking operation, resulting in insufficient load-bearing capacity and fatigue resistance of the intubation structure.
Method used
Hyperbolic cannula is adopted, which includes a straight-section cannula body and a hyperbolic transition ring. The stress concentration at the connection between the cannula and the web of the bracket is reduced through the arc transition ring, and the structural strength and fatigue resistance are enhanced.
Benefits of technology
It effectively reduces stress concentration, enhances the structural bearing capacity and fatigue crack resistance of the converter ring web, and extends the service life.

Abstract
The present invention discloses a hyperbolic insert and its application in the process hole of the support ring of a box-type water-cooled converter, and relates to the technical field of manufacturing and maintenance of the support ring of a large converter. The hyperbolic insert of the present invention is applied to the process hole of the support ring bored on the web of the converter support ring, and comprises a straight insert body and a hyperbolic transition ring; the straight insert body is inserted into the process hole of the support ring; the hyperbolic transition ring is an annular body with an arc-shaped cross-section, which is tightly fixed to the inner wall of the web of the converter support ring after being sleeved on the straight insert body. Through the arc transition, the stress concentration at the connection between the straight insert body and the web of the converter support ring can be effectively reduced, the structural strength of this part can be improved, and the service life of the web of the converter support ring can be improved. The problem of fatigue cracks caused by the high temperature and frequent flipping of the converter support ring process hole during the steelmaking operation in the prior art is solved.
