Accelerated cooling after normalizing is undoubtedly a very effective means for improving the strength of the steel plate, but if the fog cooling blow-sweeping valve is manually opened on site by an operator, the number of groups of fog cooling devices is selected, and the monitoring of steel tapping parameters is also considered, negligence and errors are easy to occur in the execution process, and the problems of energy waste and low efficiency exist when the water valve is opened all the time.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a fog-cooling blowing control device according to an embodiment of the present disclosure, in which a solenoid valve 13 may represent an area where multiple sets of water valves and air valves are installed.
The mist cooling purge control apparatus 10 includes a first grating 11, a second grating 12, a solenoid valve 13, a mist cooler 14, and a controller.
The first grating 11 is arranged at the discharging furnace door and used for sending a starting signal to the controller when detecting the material to be swept.
The second grating 12 is arranged at the joint of the tapping roller way and the input roller way of the straightening machine and used for sending a stop signal to the controller when detecting a material to be swept.
Optionally, the material to be purged in this embodiment may be a steel plate, a steel bar, or any other metal material, and the first grating 11 and the second grating 12 in this embodiment may adopt a correlation grating, so as to improve the accuracy of subsequent material detection based on the high reliability of the correlation grating under the working conditions of temperature, humidity, and iron oxide scale, and ensure the accuracy of the discharging step.
The solenoid valve 13 may include at least two air valves and at least two water valves, where the at least two air valves include a first air valve and a second air valve disposed between the first grating and the second grating, the first air valve is spaced apart from the first grating 11 by a first preset distance, and the second air valve is spaced apart from the second grating 12 by a second preset distance.
Optionally, the first preset distance and the second preset distance may be adjusted according to the discharging speed, for example, both are 0.8 m.
Optionally, the water outlets of the fog cooler 14 in this embodiment may be multiple groups, for example, 7 groups, and 3 electromagnetic valves are used as water valves to control the water outlets, and each water valve controls 3 groups, 2 groups, and 2 groups of water outlets. Wherein, every group delivery port includes respectively one delivery port in the both sides of ejection of compact roll table, and the interval distance on the ejection of compact direction of every group delivery port along ejection of compact roll table can be set for according to specific demand.
The air valve is used for controlling the compressed air positive blower and increasing the density of the blowing head, so that the scale peeled off in the mist cooling process is not bonded and is blown off in time, and meanwhile, the residual water is prevented from flowing back along the steel plate to enter the furnace and shaking on the steel plate to cool the steel plate unevenly.
The first water outlet of the mist cooler 14 along the discharging direction is close to the first grating 11, and the last water outlet of the tail portion along the discharging direction is close to the second grating 12.
Optionally, the controller is connected to the first grating 11, the second grating 12 and the electromagnetic valve 13, and is configured to control the opening and closing of the electromagnetic valve 13 based on the start signal and the stop signal, so as to control the mistcooler 14 to purge the material to be purged.
It should be understood that the Controller may be an electronic device having a Logic calculation function, such as a Personal Computer (PC), a tablet PC, a smart phone, a Personal Digital Assistant (PDA), a Micro Control Unit (MCU), and a Programmable Logic Controller (PLC).
When the controller is used for controlling the mist cooling purging, buttons can be added to a Human Machine Interface (HMI) of a Programmable Logic Controller (PLC) of the control device so as to control the electromagnetic valves 13 in groups, and the number of the groups of the electromagnetic valves 13 can be selected to realize the switching of the water valves and the air valves.
Because the discharging furnace door may generate water mist on the discharging roller table due to high temperature when being opened, the first optical grating 11 may be influenced by the water mist to be detected by mistake and start the mist cooler 14, so the embodiment can install the inductive proximity switch at the discharging furnace door to detect the opening and closing condition of the discharging furnace door, and the inductive proximity switch indicates that the discharging furnace door is opened in place and the first optical grating 11 detects the material to be swept and determines that the starting signal is successfully triggered.
Referring to fig. 2, fig. 2 is a schematic flow chart of a fog cold purging control method according to an embodiment of the present disclosure, where the fog cold purging control method may be executed by a controller, and the fog cold purging control method may include the following specific steps:
step S22: and receiving a starting signal triggered when the first grating detects the material to be blown.
The material to be swept moves to the first grating 11 from the discharging furnace door along the discharging roller way, and when the first grating 11 is shielded by the material to be swept, a starting signal is triggered and sent to the controller.
Alternatively, considering that the induction of the first optical grating 11 may be affected by water mist generated when the discharging oven door is opened, the present embodiment may be configured such that the controller receives an oven door in-place signal of an induction switch of the discharging oven door, and determines the triggering time of the start signal based on the oven door in-place signal and the start signal.
Specifically, when the first optical grating 11 sends out the starting signal but does not receive the oven door in-place signal, the starting signal is not considered to be triggered, and only when the first optical grating 11 sends out the starting signal and receives the oven door in-place signal, the starting signal is considered to be triggered.
Step S24: and receiving a stop signal triggered when the second grating detects the material to be purged.
The material to be swept moves to the second grating 12 from the first grating 11 along the discharging roller way, and when the second grating 12 is shielded by the material to be swept, a stop signal is triggered and sent to the controller.
Step S26: and calculating the starting and stopping time of the electromagnetic valve based on the triggering time of the starting signal, the triggering time of the stopping signal, the discharging speed and the distance from the first grating to the head part and the tail part of the fog cooler.
It should be understood that the first grating 11 is also generally located at a certain distance S from the head of the mist cooler 141Therefore, if the mist cooler 14 is started immediately when the first grating 11 detects a material to be purged and the mist cooling purging cannot be performed on the material to be purged, and if the mist cooler 14 is kept open in the process that the tail of the material to be purged leaves the mist cooler 14 and reaches the second grating 12, there is a problem of energy consumption waste, in order to solve the problem of energy consumption waste, the specific step of calculating the start-stop time of the electromagnetic valve in the embodiment of the present application may be as shown in fig. 3, fig. 3 is a schematic flow diagram of the calculation step of the start-stop time of the electromagnetic valve provided in the embodiment of the present application, and the calculation step may specifically be as follows:
and S261, calculating a first time length for the material to be swept to move from the first grating to the head part of the fog cooler and a second time length for the material to be swept to move from the first grating to the tail part of the fog cooler based on the discharging speed and the distance between the head part and the tail part of the fog cooler from the first grating.
Specifically, the first duration T1＝S1V, wherein S1The distance from the first grating 11 to the head of the fog cooler 14 is shown, and V is the discharging speed; a second time period T2＝S2V, wherein S2The distance from the first grating 11 to the tail of the fog cooler 14, and V is the discharging speed.
Step S262: and taking the moment when the triggering time of the starting signal is over the first time period as the starting moment of the first air valve and the water valve.
Step S263: and taking the moment when the triggering time of the starting signal passes the second time period as the starting moment of the second air valve.
Step S264: and taking the time of the duration after the triggering time of the stop signal passes the starting signal as the stop time of the first air valve, the second air valve and the water valve.
In the implementation mode, the time for the material to be blown to move to the head part of the fog cooler 14 and the tail part of the fog cooler 14 and the time for the material to be blown to pass through the first grating 11 are calculated, so that the starting and the closing of the fog cooler 14 are delayed, the material to be blown is accurately blown in a blowing range of the fog cooler 14, and the energy consumption waste of the fog cooler 14 when the material to be blown is not in the blowing range is reduced.
Step S28: and controlling the electromagnetic valve to purge the material to be purged based on the start-stop time.
Specifically, the first air valve and the water valve are opened at the starting time of the first air valve and the water valve;
opening the second air valve at the starting moment of the second air valve;
and closing the first air valve, the second air valve and the water valve at the stop moment of the first air valve, the second air valve and the water valve.
In addition, for the material to be purged with a short length, if the total length of the material to be purged is shorter than the distance between the first grating 11 and the second grating 12, the tail part of the material to be purged leaves the first grating 11, but the head part of the material to be purged does not reach the second grating 12, the fog cooler 14 stops for a short time to cause uneven cooling, so that the embodiment can keep the second air valve and the water valve in the starting state before the tail part of the material to be purged leaves the second grating 12.
