The secondary cooling shower header 21 may also be provided with a shower water total flow meter 211, which shower water total flow meter 211 is also capable of sending measured data information to the control unit 4.

The manual drain valve 31 is mainly used for maintenance.
The control method of the continuous casting secondary cooling water spray system adopts the continuous casting secondary cooling water spray system, and the control method of the continuous casting secondary cooling water spray system comprises the following steps:
Before the continuous casting is started, the workshop pipeline supplies water to the water supply main pipeline 1, the water supply amount is Q, for example, Q=60 m 3/h, and the water supply amount Q can be obtained according to experience and limited experiments. The opening of the manual valve 31 in the bleed water path 3 is at a maximum, the pressure in the bleed water path 3 is measured in real time by the bleed pressure gauge 32, the flow in the bleed water path 3 is measured in real time by the bleed flow meter 33, the flow value of the bleed water path 3 is S, and a flow signal is transmitted to the control unit 4. The main pipe manual valve 2211 is in a normally open state, the control unit 4 enables the main pipe pneumatic valve 2212 on each branch main pipe 221 to be in a closed state, the branch pipe flowmeter 2221 measures the flow of the branch pipe 222 in real time and transmits a flow signal to the control unit 4, and the control unit 4 calculates the sum of the flow values of each branch pipe 222, wherein the sum of the flow values of each branch pipe 222 is M. Because the requirement of the secondary cooling spray water is 0, the flow rate of the secondary cooling spray water system 2 is 0, and the water in the water supply main pipeline 1 completely enters the water discharge waterway 3 and then is discharged into the slag flushing ditch. The flow rate value of the drain water path 3 measured by the drain flow meter 33 is s=the water supply amount Q of the water supply main line 1 (for example, q=60 m 3/h).
And judging whether the water quantity is sufficient or not before continuous casting is started. When the flow rate value S of the water discharge path 3 is less than 70% of the water supply amount Q of the water supply main pipeline 1, the control unit 4 alarms (for example, a picture alarm occurs), reminds an operator of insufficient water amount, and the operator confirms whether continuous casting is started or not. When the flow rate value S of the water discharge path 3 is greater than or equal to 70% of the water supply amount Q of the water supply main line 1, the control unit 4 does not alarm, and continuous casting and the following flow rate control mode or pressure control mode can be performed.
When casting is started, the main pipe pneumatic valve 2212 corresponding to each flow in the secondary cooling spray water system 2 is opened according to an instruction of an operation box, 4 cooling areas connected with branch pipes 222 are sequentially opened according to the tracking condition of casting blanks, secondary cooling water is sprayed, and the secondary cooling spray water quantity is controlled through branch pipe flow meters 2221 and branch pipe electric regulating valves 2224 of each branch pipe according to the preset water meter quantity.
In the continuous casting pouring process, water in the water supply main pipeline 1 enters the two-cold spray water system 2 and the water discharge waterway 3 at the same time, the control unit 4 controls the opening of the water discharge regulating valve 34 in a flow control mode or a pressure control mode, and water flow entering the two-cold spray water system 2 and the water discharge waterway 3 is automatically distributed, so that the water flow of the two-cold spray water system 2 is ensured to be stable.
The flow control mode is that the flow value of the water discharge waterway 3 meets a flow control formula, and the flow control formula is as follows:
S＝Q×a-M；
S is the flow value of the water drainage channel 3, so that S is a set value, and the unit is m 3/h; q is the water supply amount of the water supply main pipeline 1, and the unit is m 3/h; a is a quality coefficient, and the value is 0.9-0.96; m is the sum of the flow values of each branch pipe 222, and the unit is M 3/h.
According to different production conditions, the sum M of the flow values of each branch pipe 222 is changed, and the flow value S of the water discharge waterway 3 is regulated so as to ensure the water flow of the two-cold spray water system 2 to be stable. The flow rate value of the drain water channel 3 can be adjusted by adjusting the opening degree of the drain adjusting valve 34, and the opening degree of the drain adjusting valve 34 is proportional to the flow rate value of the drain water channel 3.
Through the flow control mode, stable adjustment of various branch water volumes can be ensured, and as the water discharge waterway 3 is interlocked with the water volumes of the two-cold spray water branches 22, the state of change of various numerical values from 0 to a working value of the two-cold spray water volume during casting can be realized, and the state of the two-cold spray water volume changing to 0 during production (for example, quick-change middle tank pulling speed zero and water volume zero) can be met.
The pressure control mode is that the pressure value in the secondary cooling spray header 21 is set as a set value, and the set value can be obtained through limited experiments, for example, the pressure value in the secondary cooling spray header 21 is 0.9MPa-1.2MPa. The pressure value in the two-cold spray header 21 is stabilized at p=0.9 MPa by adjusting the drain regulator valve 34 by interlocking the drain regulator valve 34 of the drain water path 3 with the pressure value in the two-cold spray header 21 by means of pressure control. The pressure value in the secondary cooling spray header 21 can be adjusted by adjusting the opening degree of the drain regulator valve 34, and the opening degree of the drain regulator valve 34 is inversely proportional to the pressure value in the secondary cooling spray header 21.
The stable adjustment of the water flow of various secondary cooling spray water branches 22 can be ensured through a pressure control mode, and the pressure interlocking of the water discharge waterway 3 and the secondary cooling spray water main pipe 21 can realize the change state of various numerical values from 0 to a working value of the secondary cooling spray water quantity when the secondary cooling spray water is poured, and can also meet the state when the secondary cooling spray water quantity becomes 0 in the production process (for example, quick return to zero when the middle tank is quickly replaced, and return to zero of the water quantity), so that the pump stopping accident of water treatment caused by the extremely-variable secondary cooling water quantity can not be caused.
Wherein, the flow value of the water discharge channel 3 is measured by the water discharge flowmeter 33, the water supply amount of the water supply main pipeline 1 is measured by the water supply flowmeter 11, the flow value of the branch pipe 222 is measured by the branch pipe flowmeter 2221, and the pressure value in the two-cooling spray header 21 is measured by the spray water total pressure gauge 212. All the components, devices, units and modules of the invention can be manufactured by the prior art.
