US 2008/0296336 A1 · Wire Guider of Air Guide Type

Abstract

A wire guider includes a guiding unit having an inner path extending along the running direction of the wire to guide the running of the wire and an air supply unit for supplying air into the inner path to form a spiral air flow having a current rate faster than a running rate of the wire between an outer surface of the wire and an inner surface of the inner path. Wire Vibration resulting from a thrust force of mill rolls can be damped to more stably carry out one-direction running of the wire and minimize contact between the wire and a guide path. This reduces surface defects of the wire and abrasion of the guide system and protects a sensor unit from damage.

Dependent claims

A wire guider of air guide type for guiding a wire which is run in a predetermined direction, comprising:

a guiding unit having an inner path extending along the running direction of the wire to guide the running of the wire, the inner path having an inside diameter larger than an outside diameter of the wire;
and
an air supply unit for supplying air into the inner path to form a spiral air flow having a speed faster than a running rate of the wire between an outer surface of the air and an inner surface of the inner path.

A wire guider of air guide type, the apparatus comprising a sensor unit to detect the surface flaws of the wire rod while guiding one-directional movement of the wire rod, further comprising:

an entrance guider having an inner passage perforated therethrough to have an inner diameter larger than an outer diameter of the wire rod, the entrance guider being provided at an entrance of the sensor unit;
an exit guider having an inner passage perforated therethrough to have an inner diameter larger than an outer diameter of the wire rod, the entrance guider being provided at an entrance of the sensor unit;
an air supply unit for supplying air into the inner passages of the entrance and exit guiders, so as to create a spiral air flow having a higher flow rate than a movement speed of the wire rod between an outer surface of the wire rod and inner surfaces of the inner passages perforated through the entrance and exit guiders;
and
a cooling water supply unit for providing cooling water between the wire rod and a sensor bore perforated in the sensor unit for the passage of the wire rod, so as to externally cool the sensor bore.
