The embodiment explanation:
In order to verify the reliability of this monitoring method, respectively the monitoring of the different grain size oxide skin of simulated field Ultrasonic Detection operating mode, the on-line monitoring of rotary type ultraphonic transducer cavity 11 precipitums 6, the on-line monitoring of fixed ultrasonic transducer cavity 1 precipitum 6 are tested among the embodiment.
The monitoring test of the different grain size oxide skin of simulated field Ultrasonic Detection operating mode, selected the oxide skin that produces in the cooling procedure after weldless steel tube 4 thermal treatments of two kinds of granularities for use, these two kinds of oxide skins are taken from cooling zone (granularity 70 ~ 73 orders) and ultrasonic transducer cavity (290 ~ 300 order) respectively.The weldless steel tube caliber that the on-line monitoring test of the on-line monitoring of rotary type ultraphonic transducer cavity 11 precipitums 6 and fixed ultrasonic transducer cavity 1 precipitum 6 is selected for use is Φ 70.32mm, and wall thickness is 6mm, and length is 12m.Surface state is to be cooled to 40 ℃ after the thermal treatment, enters detection zone without any de-scaling operation.No matter be simulation test and the test of actual on-line monitoring, all at first need to finish reference sensitivity and proofread and correct, as Fig. 7, Figure 11, shown in Figure 15.Startup software systems Orion1.0 enters single channel and selects the pulse echo working method for use, and the echo amplitude adopts normalization to show.Adjust channel gain to 42.5dB, reflecting body echo 25 amplitudes are reached about 0.6.Enable I gate 26 and it is dragged to reflecting body echo 25 places, I gate 26 is exactly the zone of detecting in real time along the scope of time-axis direction, and the height of I gate 26 is set to 0.4.Enable gate waveform recording software function module, amplitude in the real time record I gate 26 changes, reflecting body echo record 27 is as Fig. 8 ~ Figure 10, Figure 12 ~ Figure 14, Figure 16 ~ shown in Figure 20, and the monitoring, alarming line 28 of waveform recording functional module is set to the height 0.4 of I gate 26.The alarm mode that I gate 26 is set triggers for reporting to the police for being lower than setting height.
Get 20g granularity 70 ~ 73 order oxide skins and slowly be added to precipitum feeder 13 near the front end of fallout monitoring ultrasonic transducer 14, bigger fluctuation appears in reflecting body echo 25 in the oxide skin settling process, and Fig. 9 is the result of waveform recording functional module real time record.After 20g70 ~ 73 order oxide skins all were settled down to precipitum feeder 13, reflecting body echo 25 had been positioned under the monitoring, alarming line 28, and output monitoring this moment oxide skin sedimentation alerting signal is as the stability monitoring alarm region 29 among Fig. 9.Continue to add this oxide skin, when the oxide skin amount reached 32g, its reflecting body echo 25 disappeared substantially, as shown in figure 10, the alerting signal that monitoring result output is stable, stability monitoring alarm region 29 is dotted line selected areas among Figure 10.
70 ~ 73 purpose oxide skins in the precipitum feeder 13 are removed totally, made reflecting body echo 25 amplitudes return to as shown in figure 11.Do not change the position of I gate 26.The weight of adding the equal volume correspondence gradually is that 290 ~ 300 order oxide skins of 24g are to precipitum feeder 13, reflecting body echo 24 fluctuates as shown in figure 13 in the oxide skin settling process, and the oxide skin addition begins to export the monitoring, alarming signal when reaching the 18g left and right sides.All add and be settled down to precipitum feeder 13 reflecting body echoes 25 record when 24g oxide skin and show that as shown in figure 14 record shows stablizes output alarm signal.
Precipitum 4 monitorings of fixed ultrasonic transducer cavity 1 and rotary type ultraphonic transducer cavity 11 need to start weldless steel tube 4 automatic checkout equipments, and pass through weldless steel tube 4 continuously according to the actual detected technological procedure.The installation of precipitum feeder 13 does not influence the detection performance of weldless steel tube.The speed of feed that steel pipe is set is 8m/min, starts the weldless steel tube automatic checkout equipment, the continuous weldless steel tube 4 of crossing.Figure 17 is the real-time monitoring record results of rotary type ultraphonic transducer cavity 11 reflecting body echoes 25 amplitudes, has served as the pipe number when reaching 30, the reflecting body echo 25 amplitudes also output monitoring, alarming signal that occurs descending.Figure 18 is the real-time monitoring record result of reflecting body echo 24 amplitudes of fixed ultrasonic transducer cavity 1, has served as the pipe number when reaching 18, and obviously descending appears in reflecting body echo 24 amplitudes, and output monitoring, alarming signal.The continuous pipe of crossing detects, and when rotary ultrasonic transducer cavity 11 was crossed the pipe number above 40, reflecting body echo 25 amplitudes 0.2 were in stable alarm condition, as shown in figure 19.When the mistake pipe number of fixed ultrasonic transducer cavity 1 added up 25, reflecting body echo 25 also was in the continuous alarm state, as shown in figure 20.
