Time span between the nodularization sart point in time and the nodularization end time point is the nodularization time.
During nodularization, the implementation brightness value sensed according to illuminance transducer 20, by maximum implementation brightness value mark
It is denoted as illumination peak value, and corresponding time point is time to peak point, the nodularization sart point in time and the time to peak point
Between time span be the soaring time；According to the soaring time and the soaring time is set, judges whether the soaring time is less than setting
The soaring time, if when, issue nodularization deficiency alarm.
Sandwich spheroidizing process method can delay the reaction (several seconds~more than ten seconds) of magnesium alloy, there is the iron liquid poured centainly
Highly, it just reacts after establishing a pressure head, makes to be absorbed by iron liquid as far as possible in magnesium vapor uphill process, reduce and react fierce journey
Degree, improves the rate of recovery of magnesium.When spheroidizing reacion, magnesium alloy boils rapidly and floating, and vigorous combustion, the strong light of association pass through photograph
It spends sensor 20 to detect, white flue dust (main ingredient is magnesia) is detected by dust sensor 30.
Data acquisition and pretreatment, i.e., under normal operating conditions, PLC periodically acquisition illumination and dust value simultaneously carry out data
Pretreatment.To judge convenient for subsequent analysis, adding window smothing filtering is carried out to the real time data of illumination and dust concentration value, i.e., in list
In the process cycle of position (such as 100ms), to 10 data of accumulative acquisition recently, it is averaging, obtains after rejecting maxima and minima
The average arrived is the real time value in the process cycle, and then window moves back a unit, and continuation operates repeatedly, with secondary suitable
Prolong, if primary smooth inadequate, can also carry out repeatedly smoothly having reached purpose.
According to reaction characteristics, it is that can first sense strong light, flue dust then can be just sensed after a period of time, and nodularization is anti-
The light radiation intensity reflected is very high, so can be distinguished with light source other in workshop, and if detecting light, without detecting cigarette
Dirt, that means that reacted, but because of 30 failure of dust sensor, could not sense dust, it is necessary to alert
Report, then manual intervention is repaired after the reaction was completed.Whether light radiation intensity or dust concentration be all for entire nodularization process
It is the curve slowly declined after riseing to highest point, so in a period of time, light radiation is strong if normal reaction
Degree and dust concentration will drop under threshold value, that is, complete spheroidizing reacion, can be calculated nodularization process when
Between, fall time is also an important parameter for technique, can be obtained by nodularization time and the difference of soaring time.
If spheroidizing reacion has occurred to early, that is, the soaring time is inadequate, so also it is insufficient that nodularization can be issued according to this data
Alarm.
Judge that nodularization starts and the end time by light radiation intensity and dust concentration, data handling procedure is mainly by two
Part forms, i.e. plc data process flow and upper computer software flow chart of data processing.
In the case of normal operating conditions, upper computer software records illumination and dust curve data in real time, when detecting nodularization
After end mark, nodularization time started, nodularization end time, nodularization time are read, nodularization is resetted and starts to terminate to mark with nodularization,
It prepares for next round nodularization operation.
Under nodularization deficiency abnormal conditions, upper computer software automatically records nodularization deficiency data and flag event, takes emergency
Measure or progress molten iron are scrapped after being disposed, and resetting PLC nodularization by host computer, brightness value time to peak, nodularization is insufficient
The label such as alarm, record.
In the case of illumination or dust anomaly sensing, upper computer software detects illumination or dust transmitter warning mark, touching
Dimension event is shipped, if still untreated in the stipulated time, periodically upgrade alarm level, such as pushes O&M to person in charge step by step
Event, until abnormal problem solves.After site operation personnel confirms, host computer resets warning label, can formally use.
