US 8,740,123 B2 · Replaceable wear element for rolling mill laying head

Abstract

Selectively replaceable wear elements for rolling mill laying heads. One replaceable wear element forms the end ring guide surface and is installed within the end ring inner diameter without removing the guide ring from the laying head. A plurality of wear element bodies may be installed about one or more portions of the end ring guide surface inner diameter. Size, configuration and material properties of the end ring guide surface wear element bodies may vary for different sections within the ring guide inner diameter. Another replaceable wear element is a tripper paddle that forms a laying head tripper mechanism guide surface. The tripper paddle and guide surface wear element bodies are replaceable external the end ring without removing the end ring or tripper mechanism from the laying head. Either or both types of wear element may be used in a laying head.

Dependent claims

In a laying head system for coiling hot rolled elongated material, the system having a generally annular end ring for guiding elongated material discharged from the laying head into a continuous coil that is in turn discharged from the end ring, the end ring having an inner diameter radially and axially circumscribing the elongated material and defining respective proximal and distal axial sides, a selectively replaceable guide surface lining at least a portion of the end ring inner diameter comprising a wear element body having:

a curved inner surface defining at least a portion of the guide surface;
an outer surface having a profile conforming with a guide ring inner diameter that is adapted for mated coupling with the guide ring inner diameter;
and
an engagement surface adapted for mating engagement with a fastening element that is coupled to the end ring, the wear element body, when engaged with the fastening element and end ring, forming at least a portion of the guide surface.

In a laying head system for coiling hot roiled elongated material, the system having a generally annular end ring for guiding elongated material discharged from the laying head into a continuous coil that is in turn discharged from the end ring, the end ring having an inner diameter radially and axially circumscribing the elongated material and defining respective proximal and distal axial sides, a method for selectively replacing a guide surface lining at least a portion of the end ring inner diameter comprising:

providing a wear element body having:
a curved inner surface defining at least a portion of the guide surface;
an outer surface having a profile conforming with the guide ring inner diameter that is adapted for mated coupling with the guide ring inner diameter;
an engagement surface adapted for mating engagement with a fastening element that is coupled to the end ring, the wear element body, when engaged with the fastening element and end ring, forming a portion of the guide surface;
mating the wear element body outer surface with a corresponding surface of the end ring inner diameter;
and
fastening a fastening element to the end ring and the wear body engagement surface, thereby forming at least a portion of the end ring guide surface with the wear body inner surface.
