Description
Technical field
The utility model relates to a kind of slab water seaoning UT (Ultrasonic Testing) field, is applicable to the flaw detection of 100-450mm thickness slab.
Background technology
The inner all kinds of defectives of slab are very large to the quality influence of product, and the slab manufacturing plant of general iron and steel enterprise has all disposed the operation of slab UT (Ultrasonic Testing).Owing to be subject to the restriction of slab production technology, reach the slab that 10000mm * 1600mm or maximum ga(u)ge reach 350mm for area full-size and implement UT (Ultrasonic Testing), have no idea to dispose the automatic ultrasonic flaw-detecting unit at the plate slab production line, the quality testing of slab can only adopt the method for artificial ultrasound wave inspection to carry out.
Existing artificial ultrasound ripple detects, and can only adopt contact method flaw detection or the flaw detection of local water seaoning.The contact method flaw detection is subject to various technical conditions restrictions, and detection efficiency is low, and detecting reliability is poor, and testing result fluctuates with human factor, and there is very big risk in slab quality.Simultaneously and since the operating type of manual contact method UT (Ultrasonic Testing) be operating personnel must couchant operations, therefore, labour intensity is large, and has limited the raising of pulling the base production capacity.
Local water seaoning flaw detection is different according to distance between probe and the workpiece, can be divided into water seaoning and moisture film method.The detection probe of water seaoning does not directly contact with workpiece, keeps certain water layer to detect between tested workpiece and the probe.The very thin water of one deck is arranged as couplant between the detection probe of moisture film method and the workpiece, the effect of couplant is the air of getting rid of between probe and the surface of the work, makes ultrasound wave effectively import workpiece into, reaches testing goal.Moisture film method detection type is similar to contact method.If adopt the water seaoning flaw detection, because water seaoning flaw detection coupled water realizes that by bath probe holder and slab are when doing relative motion in the flaw detection process, phenomenon of losing water can occur in coupled water, and the bath cause the coupled water instability of flow, can cause the flaw detection report by mistake, affect flaw detection effect.The blind area increases if the flaw detection of employing moisture film method can cause detecting a flaw, and is unfavorable for surveying the workpiece near surface flaw, affects equally flaw detection effect.
Existing slab flaw detection is to adopt the artificial ultrasound ripple to detect, and generally adopts the flaw detection of contact method or local water seaoning.Adopt the probe of contact method flaw detection directly to contact with slab, be coupled with machine oil or water between probe and the slab, because there are a large amount of iron scales in steel slab surface, probe contacts directly impact flaw detection coupling effect with slab, cause the testing result poor reliability, testing process flaw detection signal fluctuates, and the flaw detection blind area is large.Adopt local water seaoning flaw detection, because the water seaoning coupled water realizes that by bath probe need be done relative motion with slab in the flaw detection process, phenomenon of losing water can occur in coupled water, causes flaw detection to be reported by mistake.
