Description

The invention relates to the automation of rolling mills.

A device for collecting information about the technological parameters of a strip is known, which contains gauges for the parameters of rolled metal that are connected via keys to counters with a length of 1J.

However, the information obtained during rolling is not complete for the analysis of the technological process.

Closest to the invention in its technical essence is a device comprising a process variable sensor, a sensor and length counters. Depending on the magnitude of the deviation of the technological parameter from the specified value, the switch, via a switch, connects one of the counters to the sensor for the length pulses. The corresponding counter shows the length of the strip rolled in this zone of deviations of the technological parameter. Switching to another counter, indicating a failure in another zone, is performed by switching the switch.

However, the information obtained during rolling does not allow one to judge about the technological parameter of the rental at each of its sections, which is necessary for the evaluation of the technological process.

In addition, the use of a pulse sensor in the process stream is associated with certain technical difficulties associated with driving it, which leads to

On ф г, I the block-bhema of the device is shown for automatic gathering information about the rolled-on technological parameters pax for a given number of sections of its length; in fig. 2 is a block diagram of the installation of the device in the initial state. 3 The device contains a sensor for monitoring the technological parameter of the flow, connected via keys 2–4 to blocks 5–7 of the averaging technological parameter, whose elevations are connected to indicators 8–10 for each given zone of the length of hire, to the control inputs of the keys are connected the switch I1 of the serial number of zones of the rental length, the gauge 12 of the rolled stock after the first stand, the gauge 13 of the presence of rolled metal in the measuring zone of a technological parameter, the gauge 14 of the number of zones of control of the technological parameter, the gauge of 1 pulses, divides Spruce 16 pulses with a predetermined division factor, two keys 17 and 18, two counters 19 and 20 pulses, rewriting circuit 21, registrar 22, comparison circuit 23, one-shot 24, device installation unit 25 in the initial state. In this case, the information inputs of the keys are connected, to the output of the pulse sensor, the control input of the first key is connected to the sensor for the presence of rolled metal in the beginning of the mill, the output of this key is connected via a pulse separator to the input of the first pulse counter, which is connected to a master. On the control of the 1st input of the second key, the sensor of the presence of a protoc is connected in the measurement zone of the technological parameter. The output of the second key is connected to the input of the second pulse counter, the information outputs of the second pulse counter and register are connected to a comparison circuit whose output is connected to the second input of the switch of the serial number of the rental length zone and through the one-shot to the installation bus to the initial state of the second pulse counter, Task The number of zones of the rental length is connected to the control input of the pulse splitter. The sensors for the presence of rolled metal are connected to the input of the device installation unit, and the first output is connected to the control bus of the rewriting circuit, the second output from the bus to zero of the first count of pulses, and the third output to the bus of installation to zero register , the fourth - with the switch installation bus in the initial state, the fifth - with the installation bus in the initial state) of the averaging units of the process parameter 344 for each predetermined area of the hire length. The device works as follows. After the occurrence of rental in the area of the sensor I2 of the presence of rental at the input 1 of the key 17, a signal is obtained to allow the passage of pulses from the sensor 15 of pulses. From the output I of the switch 17, the pulses go through a divider 16 with a predetermined division factor K to the input 1 of the counter 19 pulses. The division factor K is set before starting work by setting unit 14 and determines the number of control zones, i.e. . The number of sections of the length of the rental, each of which receive the value of the controlled parameter, for example, temperature. After the rental has left the rental zone of the sensor 12, the key 17 is closed, the pulse counting is stopped. From the output I of the device setting unit 25 to the initial state 1, a signal is fed to the control input of the rewrite circuit 21 enabling the rewrite of the pulse counter 19 pulses to the register 22. After the rewriting is over, the output 2 of the block 25 with a delay appears shortly on the reset buses counter 19 pulses. Pulse counter 19 is reset to its original state and, thus, is prepared to receive further information. The initial state of the switch 11 presence-signal logical 1 resolution) on the first channel. The sensor 13 availability of rental and sensor 1 control technological para-, meters are installed on the same line to the axis of rolling. After the front end of the hire appears in the sensor 1 control zone, the parameter value via key 2 enters averaging block 5 and is displayed on the display 8. At the moment the front end of the rolled stock in the sensor 13 zone is present, the input 1 is set. allowing the passage of pulses from the sensor 15 pulses to the input of the counter 20 pulses. Since the rental in the mill is related to the rarity of the second volumes, the time it is under the sensor 12 for the presence of rocat after the first stand and sensor 510

com 13, the presence of rolled metal in the measurement zone is the same, i.e. the output of keys 17 and 18 will pass the same number of pulses N, But, since there is a divider in one of the channels, then the counter 19 pulses, and therefore the register 22 receives the number of pulses equal to -JT-.

Thus, after passing the number of pulses to the input of the counter 20 pulses -JT-, the number of pulses recorded in register 22 and the number of pulses received in the counter of 20 pulses will be equal and the comparison circuit 23 causes the pulse 2 of the switch 11 and the input of the one-oscillator 24, which, by a short pulse, resets the pulse counter 20 to the initial state.

After the arrival of the pulse from the comparison circuit 23 to the input 2 of the switch 11, the key 2 of the first port is closed and the key 3 of the second measurement zone is opened.

During the time that the probe is located in the zone 13 of the presence of rolled metal, the comparison circuit 23 brings impulse 4 A to switch 11 K-1, since the key 2 of the first measurement zone is switched to the initial state of switch 11, K-1 pulses at the input of switch 11 will switch to the measurement zones. The values of the paramaters in each zone are averaged in blocks 5-7 and displayed on indicators 8-10.

FIG. 2 shows the circuit of the device installation unit 25 in the initial state, to the inputs of which the sensors 12 and 13 are available for hire, the first output is connected to the control bus of the rewriting circuit 21, the second output is connected to the reset bus of the pulse counter 19, the third output is by bus

setting the initial state of register 22, the fourth output - with the installation bus into the initial state of the switch 11, the fifth output - with the installation bus returning to the initial state of the process parameter averaging blocks 5-7 for each predetermined rental length zone.

The signals of the device installation unit 25 are generated in the initial state at the following points in time: at output I, a rewrite control signal appears at the moment when the rear end of the car leaves the rental zone 12; At output 2, a reset signal to the initial state 1 above the pulse counter 19 appears with a delay after the rear end of the car leaves the rental zone 12;

At output 3, the setup signal of the initial state of register 22 appears at the moment when the rear end of the car leaves the zone 13 of the presence of rolled products;

at output 4, the set-up signal of switch 11 is detected at the moment when the rear end of the car leaves the rental zone 13;

At output 5, the signal of initialization of the blocks of 5-7 averaging appears at the moment when the front end of the rental enters the zone of the sensor 13 for the presence of rolled products.

The information is used to analyze and control the process. The use of a device to control the temperature of rolled products along the length allows one to correctly construct the heating mode, speed, mode and shower mode.
