Problems solved by technology

However, in the actual working environment, the high temperature limit element is too close to the high temperature casting slab
Because the limit element works in a high temperature environment for a long time, it often appears unstable (such as internal short circuit, open circuit, virtual connection, etc.), resulting in PLC control disorder or PLC template damage
Therefore, due to the influence of the terminal limit of the billet discharge area, the automatic billet discharge system cannot correctly judge the signal and cannot realize the statistical function of the cast billet, which affects the standardization, refinement and data collection of continuous casting machines. problem with serious impact

Embodiment 1

[0020] A signal detection device in a high-temperature area, comprising a cantilever hanging ball-type limiting device 4 and a control circuit, the forearm of the cantilever-hanging ball-type limiting device 4 is connected to a movable hanging ball 8 with a high-temperature-resistant flame-retardant cable 7, and the resistant The length of the high-temperature flame-retardant cable 7 ensures that the movable hanging ball 8 is fully in contact with the upper surface of the cast slab 1, and the cantilever hanging ball-type limiting device 4 is connected to the corresponding terminal of the grounding row of the main electrical room; the corresponding terminals of the control circuit are respectively The corresponding terminals of the grounding bar 11 in the power connection room and the high-temperature-resistant flame-retardant cable 7; the industrial computer is connected to the control circuit through the PROFIBUS bus; the industrial computer is equipped with an HMI man-machine ...

Embodiment 2

[0031] A method for counting slabs. When a limit signal detection program is configured in a control module to detect a limit signal, the HMI man-machine control program installed in an industrial computer is notified to perform an increase counting operation and display a statistical result.

[0032] The slab counting method further includes that the HMI man-machine control program receives the input operation commands of adding, subtracting and counting back to zero, and correspondingly adds, subtracts and counts back to zero on the statistical results.

[0033] When the limit signal detection program configured in the PLC input template detects the limit signal, it will notify the HMI man-machine control program installed in the industrial computer to perform an increase counting operation and display the statistical results.

[0034] Using the original billet PLC control system, compile the statistics of the number of billets. The contact signal of the intermediate relay 1...

Abstract

The invention discloses a high-temperature region signal detection device and a casting blank counting method. The device comprises a cantilever hanging ball limit device and a control loop, the lowerportion of the cantilever hanging ball limit device is connected with a movable hanging ball by the aid of a high-temperature-resistant fire resistant cable, and a relay in the control loop is controlled by the hanging ball to generate limit signals when casting blanks come. According to the counting method, the number of the casting blanks is counted by the aid of limit detection signals received by an industrial control computer. Limit signals can be stably detected, an automatic knockout control function in a high-temperature region is achieved, continuous casting and continuous casting machine data statistics are ensured, and continuous casting operation standard refinement and product quality are improved.

Description

technical field [0001] The invention relates to a signal detection device and a billet counting method, in particular to a signal detection device in a high temperature zone and a billet counting method, and belongs to the technical field of automatic detection and control of continuous casting machines. Background technique [0002] Generally, the signal detection devices installed in the billet discharge area of ​​the continuous casting machine are all high-temperature-resistant limit elements, and the limit elements are used as input signals, which are input into the template through PLC, and then controlled by logic programs. However, in an actual working environment, the high-temperature-resistant limiting element is too close to the high-temperature casting slab. Because the limit element works in a high temperature environment for a long time, it often appears unstable (such as internal short circuit, open circuit, virtual connection, etc.), resulting in PLC control d...
