Abstract
The present invention relates to the online detection medium plate of a kind of ultrasound wave method, online 100 ℃～350 ℃ medium plate 1 in back is sheared in hot rolling, after nozzle 2 water spray coolings, steel plate 1 enters failure detector 3 by means of auto-reverse speed change roller-way 8 with the sweep velocity that non-destructive testing standard requires, probe jacking gear 4 put down ultrasonic probe from device for cooling 5 be pressed on the steel plate 1 equably, backing plate 7 is steel plate 1 leveling, steel plate 1 12 detects by popping one's head in, and flaw detection is after wiper 6 is removed the water of its remained on surface.Advantage of the present invention is to realize online disposable detection steel plate inherent vice, has quick, accurate and easy characteristics.
Description
The present invention relates to a kind of method of utilizing the online detection medium plate of ultrasound wave, realize by ultra-sonic defect detector and probe apparatus, it is characterized in that, online 100 ℃～350 ℃ medium plate in back is sheared in hot rolling, after the water spray cooling, medium plate enters failure detector with the sweep velocity that non-destructive testing standard requires, and defectoscope carries out disposable flaw detection with ultrasonic probe from device for cooling centering steel plate.Ultrasonic probe is to be made of friction copper packing 9, overcoat 10, water layer thickness setting nut 11, double crystal probe 12, interior cover 13, inlet opening 14 and probe fixing pullover 15 from device for cooling 5, guarantee to have water to pop one's head in 12 cool off and pop one's head in 12 and steel plate 1 between be full of the flaw detection medium.
Offline inspection is adopted in hot rolling medium plate flaw detection at present, must treat just to detect a flaw after the hot rolling medium plate cools off fully, so, not only take a lot of work but also time-consuming, and floor area is big, has influence on the cycle that steel plate is produced.
The object of the present invention is to provide the method for the online UT (Ultrasonic Testing) of a kind of hot rolling medium plate, adopt ultrasonic probe, eliminate the influence of temperature, be implemented in the inherent vice that detects medium plate on the production line fast, easily UT (Ultrasonic Testing) from device for cooling.
Purpose of the present invention can reach by following measure: online 100 ℃～350 ℃ medium plate in back is sheared in hot rolling, after the nozzle water spray cooling of auto-cool system, medium plate enters in the ultrasonic flaw detecting device with the sweep velocity that non-destructive testing standard requires by means of auto-reverse speed change roller-way, the probe jacking gear puts down ultrasonic probe and also is pressed on the cut deal equably from device for cooling, backing plate is the medium plate leveling, medium plate detects by probe, and the medium plate after the flaw detection strikes off its remained on surface water through wiper.Ultrasonic probe is in device for cooling, in overlapping in double crystal probe is enclosed within, its below is by fixing pullover connection of screw thread and probe, its top is compressed by the water layer thickness setting nut, overcoat is connected with interior external threading, overcoat is embedded with the friction copper packing, and overcoat top has the inlet opening, guarantee have water that probe is cooled off and probe and steel plate between be full of the flaw detection medium.
The present invention is further described below in conjunction with accompanying drawing: accompanying drawing 1 is the online defect detection on ultrasonic basis synoptic diagram of hot rolled steel plate of the present invention.Accompanying drawing 2 is the self cooling apparatus structure synoptic diagram of ultrasonic probe.
Hot rolling is sheared online 100 ℃～350 ℃ medium plate 1 in back after the nozzle 2 water spray coolings of auto-cool system, medium plate 1 enters in the ultrasonic flaw detecting device 3 with the sweep velocity that non-destructive testing standard requires by means of auto-reverse speed change roller-way 8, probe jacking gear 4 puts down ultrasonic probe and also is pressed in equably on the medium plate 1 from device for cooling 5, backing plate 7 is medium plate 1 leveling, medium plate 1 detects by ultrasonic probe 12 and from device for cooling 5, and the medium plate 1 after the flaw detection strikes off the water of its remained on surface through wiper 6.Ultrasonic probe is in device for cooling 5, cover was 13 li in double crystal probe 12 was enclosed within, its below is by the probe fixing pullover 15 that is threaded, its top is compressed by water layer thickness setting nut 11, overcoat 10 is threaded with interior cover 13, overcoat 10 is embedded with friction copper packing 9, and overcoat 10 tops have inlet opening 14, guarantee to have water to pop one's head in 12 cool off and pop one's head in 12 and steel plate 1 between be full of the flaw detection medium.
The present invention has following advantage compared to existing technology: realize the online disposable detection of produced on-site hot rolling medium plate, and have quick, accurate and easy characteristics.
