Description

Technical Field

[0001] The utility model belongs to the technical field of flaw detection, and in particular relates to a steel bar automatic flaw detection line deicing device. Background Art

[0002] The steel bar automatic flaw detection line is a highly efficient automated non-destructive testing equipment that uses eddy current flaw detection and ultrasonic flaw detection technology to detect surface defects and internal defects of steel bars. It can accurately and effectively detect various defects in bars and has the advantages of fast speed and high sensitivity. It is widely used in special steel bar finishing lines.

[0003] The testing fluid medium of the steel bar automatic flaw detection line is water. When the outdoor temperature in the northeast region drops below -20℃ in winter, a large amount of testing fluid will remain on the surface of the steel bar after the steel bar is output from the eddy current flaw detection box. When the steel bar encounters cold air, the surface of the steel bar will immediately freeze to form a wrapped ice layer with a thickness of 0.1 to 0.2 mm, causing the steel bar to slip on the conveyor roller and unable to be inspected and cleaned during subsequent inspections of the steel surface.
