Abstract
The utility model discloses a tundish car control device of a continuous casting machine, and is characterized in that the device comprises an AC variable frequency motor used for providing power for the tundish car, a frequency changer used for variable frequency speed regulation of AC variable frequency motor, and a PLC used for providing predetermined signal for the frequency changer; the PLC is connected with the frequency changer through an output module; the output end of the frequency changer is connected with the input end of the AC variable frequency motor after outputting predetermined voltage signal to the frequency changer to control the input value adjustment of the AC variable frequency motor so as to control the running speed of the tundish car. The device controls the speed regulation of the tundish car, and the walking is controlled according to certain model. Thus, the tundish car can be quickly and stably changed during the casting process, thereby having small effect on the whole continuous casting machine, reducing the machine halt or steel leakage rate, simultaneously improving the continuous casting rate of the continuous casting machine; and the accident rate of the continuous casting machine can be greatly reduced, thus the device is suitable to be extensively popularized in the continuous casting machine.
Description
Technical field
The utility model relates to a kind of hired car control device, relates in particular to a kind of conticaster tundish truck control device.
Background technology
Slab caster requires in the casting cycle of conticaster, often needs to change tundish, and this just need control the centre hired car, and the walking of hired car all is common alternating current generator transmission control in the middle of the general conticaster.Bring following problem in the use: 1. rise, brake not steady; 2. speed is single; 3. the bleed-out accident takes place in inconvenient operation easily.
Summary of the invention
The utility model is at the proposition of above problem, and develop a kind ofly brake steadily, the accurate and easy to operate hired car control device of centering.The technical solution adopted in the utility model is:
A kind of conticaster tundish truck control device is characterized in that comprising:
Alternating-current variable frequency motor is used to hired car that power is provided;
Frequency converter is used for alternating-current variable frequency motor is carried out frequency control;
PLC is used for providing given signal to frequency converter;
Described PLC is connected with frequency converter by output module, and behind the given signal of frequency converter output voltage, the output of frequency converter is connected with the input of alternating-current variable frequency motor, with the input value adjustment of control alternating-current variable frequency motor, controls the speed of service of hired car with this.Described frequency converter is connected with brake unit.
The frequency control motor that this programme provided carries out speed regulating control to the centre hired car, and its walking is to control according to certain model.In casting cycle, can change tundish fast, stably like this, little to the influence of whole conticaster, reduced the probability of shutdown or bleed-out, rate is watered by the company of having improved conticaster simultaneously.After adopting this scheme to replace traditional AC Motor Control, make equipment rise, brake steadily, parking centering is accurate, operates also very conveniently, can reduce the accident rate of conticaster greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a structured flowchart of the present utility model.
The specific embodiment
This programme is that this electric control system has been carried out design improvement as shown in Figure 1, with common AC Motor Control system, changes into and uses the Frequency Converter Control alternating-current variable frequency motor, adopts AC frequency conversion apparatus by PLC variable-frequency motor to be controlled.We are to control by the voltage signal that PLC provides to the given signal of converter plant, and this conticaster tundish truck control device comprises: alternating-current variable frequency motor 103 is used to hired car that power is provided; Frequency converter 102 is used for alternating-current variable frequency motor is carried out frequency control; PLC 101, and being used for provides given signal to frequency converter; Described PLC 101 is connected with frequency converter 102 by output module, behind the given signal of frequency converter 102 output voltages, the output of frequency converter 102 is connected with the input of alternating-current variable frequency motor, input value adjustment with the control alternating-current variable frequency motor, control the speed of service of hired car with this, frequency converter is connected with brake unit 104 to prevent that direct current overvoltage fault appears in frequency converter in the braking procedure.
This device is by the internal control system of debugging, realizes control to centre hired car walking according to certain Mathematical Modeling, finally reaches the purpose of steady centering.The basic controlling process:
1) provides analog signals by output module.
2) establishment Mathematical Modeling.
3) walk according to Mathematical Modeling control tundish garage.
4) finish steady centering.
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and inventive concept thereof, all should be encompassed within the protection domain of the present utility model.
