Embodiment one
Fig. 1 is a kind of flow diagram of annealing furnace water quenching nozzle valve control method in the embodiment of the present invention.Such as Fig. 1 institute
Show, the embodiment of the invention provides a kind of annealing furnace water quenching nozzle valve control methods, which comprises
Step 110: obtaining operation mode, the operation mode includes automatic mode and local mode.
Further, the acquisition operation mode, the operation mode include packet after automatic mode and local mode
It includes: when the operation mode is local mode, obtaining user instruction；According to the user instruction, the second corresponding valve is obtained
Open information；Information is opened according to the described second corresponding valve, controls corresponding water quenching nozzle valve opening.
Specifically, the control method of water quenching nozzle valve described in the embodiment of the present invention be divided into remote automation mode and
Long-range local mode, is specifically chosen according to operational circumstances, and when selecting the local mode, concrete operations are to pass through system
Interface manually carries out the selection of valve, and the valve title that selection is accordingly operated is directed to according to the concrete condition of strip
Property selection, need a large amount of water quenchings strip select multi-quantity valve open, conversely, selection small number valve open, determine
After the quantity for opening valve well, clicking operation button, by the opening state for remotely controlling water quenching nozzle valve.
Step 120: when the operation mode is automatic mode, obtaining strip information, predetermined threshold.
Further, the strip information includes: steel strip thickness value, strip speed value.
Specifically, when selecting automatic mode, i.e., the described remote automation mode, due in remote automation mode
When the setting of its on-line operation starting require to have to require the quantity opened come control valve according to the corresponding water quenching of strip information
Body is to require to obtain with the result that the predetermined threshold of each valve setpoint is judged by the water quenching of the strip of acquisition
Starting requires, and the water quenching of the strip requires to be determined by the thickness of the strip and the velocity amplitude of strip, thus when operation
When mode is automatic mode, need to obtain strip information and predetermined threshold to carry out corresponding operation control.
Step 130: according to the strip information, obtaining strip water quenching parameter.
Further, described according to the strip information, obtain strip water quenching parameter, comprising: according to formula LSD=δ * V/
lsdmax* 100%, obtain strip water quenching parameter；Wherein, LSD is strip water quenching parameter, and δ is steel strip thickness, and V is strip speed,
lsdmaxFor water quenching maximum parameter.
Further, the lsdmaxFor 450m*mm/min.
Specifically, calculating strip water quenching parameter according to the strip of acquisition information, that is, steel strip thickness, strip speed
LSD, for example, system obtain strip with a thickness of 1.5mm, speed of service 120m/min, pass through and calculate LSD=1.5*
120/450*100%=40%, wherein lsdmax=2.5*180=450m*mm/min passes through the thickness according to strip, operation speed
It spends to judge water that water quenching needs, reference tape molten steel parameter of quenching judge the unlatching quantity of valve, so as to meet band
Molten steel is quenched requirement, guarantees strip quality.
Step 140: being compared using the strip water quenching parameter and the predetermined threshold, when the strip water quenching parameter meets
When the predetermined threshold, obtains the first corresponding valve and open information.
Step 150: information being opened according to the described first corresponding valve, controls the water quenching nozzle valve opening of corresponding number.
Further, described to be compared using the strip water quenching parameter and the predetermined threshold, when the strip water quenching is joined
When number meets the predetermined threshold, obtains the first corresponding valve and open information, specifically include: when the strip water quenching parameter meets
In the predetermined threshold when first threshold, the opening information of the first valve corresponding with the first threshold is obtained；When described
When strip water quenching parameter meets second threshold in the predetermined threshold, first valve corresponding with the second threshold is obtained
The opening information of door and the second valve；Wherein, the first threshold is less than the second threshold.
Specifically, compared according to the strip water quenching parameter LSD being calculated and presetting parameter, thus
System judges the valve quantity that open, and is automatically turned on, and guarantees the requirement of strip water quenching, makes the number of Open valve
Amount meets the requirement of production technology, and the predetermined threshold is the parameter value setting that each valve is opened, as shown in following table one:
Table one
| Valve is opened | LSD (is converted to %) |
| 81-200038-EV05 | > 0% (can modify) |
| 81-200038-EV04 | > 8% (can modify) |
| 81-200038-EV03 | > 35% (can modify) |
| 81-200038-EV02 | > 60% (can modify) |
Water quenching nozzle valve is divided into four groups, respectively 81-200038-EV02,81-200038-EV03,81-200038-
EV04,81-200038-EV05, when 0% or more strip water quenching parameter being calculated, then 81-200038-EV05 valve is opened,
At 8% or more, then 81-200038-EV04 valve is opened, and when it is 20% that LSD value, which is calculated, then opens two valves
Door, respectively 81-200038-EV04 and 81-200038-EV05 then open two valves, respectively when LSD is 40%
The rest may be inferred described in 81-200038-EV03,81-200038-EV04 and 81-200038-EV05.For example, system obtains band
Steel with a thickness of 1.5mm, speed of service 120m/min, by the way that LSD=1.5*120/450*100%=40% is calculated,
Wherein lsdmax=2.5*180=450m*mm/min, according to the concrete condition of predetermined threshold, predetermined threshold pair as shown in Table 1
It than as it can be seen that the predetermined threshold includes multiple threshold values, and is arranged according to ascending sequence, when the strip water quenching parameter
When LSD meets corresponding threshold value, the correspondence water valve for meeting threshold requirement is opened, the band molten steel obtained due to system-computed
After parameter of quenching LSD result is 40% and the comparison of table one, 60% > LSD of calculated result > 35%, thus meet 81-200038-
The unlatching requirement of EV03,81-200038-EV04 and 81-200038-EV05 valve, is opened, according to the LSD numerical value of strip
Three valves are opened, and then meet the requirement of strip water quenching, realize the accurate control to annealing furnace water quenching nozzle valve, are solved
In the prior art since the type of strip and the actual speed of service are different, the opening quantity of four valves is not able to satisfy production
The technical issues of technique requires.The quantity opened using the calculated value of strip LSD parameter come control valve is reached, has greatly improved
The accuracy of valve opening, enhances equipment reliability of operation, ensure that temperature in condition range that production is well run
Stable regulation.By the accurate control of annealing furnace water quenching nozzle valve, functions of the equipments on perfect system pipeline, to keep away
The defects of exempting from the inhomogeneous cooling bring macula lutea quality that strip occurs due to valve quantity controls bad water quenching and cannot meet the requirements,
It it has been able to extend the service life of heat exchanger, reduces consumption and the electric quantity loss of circulating pump and attachment, it is effectively guaranteed that being
The technical effect of the efficient stable operation of system.In addition the control method of the embodiment of the present invention is additionally provided with parameter modification interface, can
To carry out concrete modification to predetermined threshold according to the concrete condition of strip, water quenching requirement, production line situation, and guarantee various bands
The technique requirement of steel, adaptability are more extensive.
