Title:
DEVICE FOR NONDESTRUCTIVE TESTING OF ESPECIALLY HOT, BAR-SHAPED ROLLING MATERIAL
Document Type and Number:
WIPO Patent Application WO2000077513
Kind Code:
A9
Abstract:
A device for nondestructive testing of especially hot, bar-shaped rolling material above Curie point during the rolling process by means of an exploring coil system which can be impinged upon by a coolant and which rotates around the rolling material passing therethrough. Said exploring coil system consists of at least two exploring coils. The invention is characterized in that the inventive device is arranged directly downstream from the point where the rolled product exits from the roll stand on the roller cooling system associated therewith. The invention is further characterized in that the coolant for the explorer coil system is fed into the rotating system essentially on the same plane as the one on which the device is secured to the roll stand, wherein a channel for said coolant is provided, extending in a threaded manner between the rolled product and the rotation bearing and wherefrom individual ducts lead to the respective explorer coils in a radial manner.
