Abstract

The utility model relates to a steelmaking process automatic control technical field especially relates to a converter tapping quantity automatic acquisition system, including empty can crane, heavy jar crane, converter PLC controller, control level computer and management level computer, set up counterpoint limit switch and wireless transmitter on empty can crane and the heavy jar crane respectively, set up wireless receiving device and tapping quantity calculation module in the converter PLC controller, set up tapping quantity communication module in the control level computer, to tapping quantity calculation module's calculation tapping quantity value automatic acquisition. And after the heavy tank crane weight is identified, the control level computer sends the tapping amount communication data and the tank number to the management level computer together in a telegraph text mode, and the tank number is specified by the management level computer. Compared with the prior art, the beneficial effects of the utility model are that: the influence of human factors on the steel output error of the converter is avoided, the working strength of operators is reduced, the system is stable and reliable in operation, and the automation degree and the control precision of the steel-making system are improved.

Description

A kind of converter tapping amount automated collection systems

Technical field

The utility model relates to steelmaking process automatic control technology field, relates in particular to a kind of converter tapping amount automated collection systems.

Background technology

At present, artificial calculating and recording mode adopted in the calculating of oxygen top-blown converter tap, at first, and by operator's hand-kept jar number; Secondly, after crane is sling empty molten steel jar, the data on the weight display screen of slack tank crane are read and manually write down slack tank weight by the operator; Once more, after crane will weigh the molten steel jar and sling, the heavy molten steel jar weight data that shows on the crane screen is carried out record by the operator; At last, the heavy jar weight and the slack tank weight of this molten steel jar correspondence are carried out subtraction by the operator, and the converter tapping amount result of hand-kept calculating.

The major defect that the method exists is:

1) crane screen and operator's distance is far away, if the operator has defective vision, sight line is not good or during the careless operation of operator, cause error in reading easily:

2) after the operator notes slack tank weight and weighs jar weight, carry out subtraction by the operator, if error of operator's mathematical computations or carelessness cause the data computation mistake easily;

3) operator carries out manual record to reading and result calculated, if the operator writes not carefully and neatly done or keyboard input error, causes information typing mistake easily;

4) every production all will be carried out reading, calculating, writing task for one jar, and operator's workload is bigger.

Above-mentioned by hand-kept calculating converter tapping amount, labor strength is bigger, causes error in data easily, will directly have influence on the calculating and the control accuracy of robotization steelmaking system.

Summary of the invention

The purpose of this utility model provides a kind of converter tapping amount automated collection systems, the error of avoiding the human factor influence to cause, the automaticity and the control accuracy of raising steelmaking system.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind of converter tapping amount automated collection systems, comprise slack tank crane, heavy jar crane, converter PLC controller, controlled stage computing machine and management level computer, on slack tank crane and the heavy jar crane contraposition limit switch and transmitting set are set respectively, radio receiver and tap computing module are set in the converter PLC controller, the tap communication module is set in the controlled stage computing machine, the calculating tapping value of tap computing module is gathered automatically.

Described controlled stage computing machine after heavy jar of crane weight identification with the tap communication data with jar number send to management level computer with telegraph text form in the lump, jar number specify by management level computer.

Compared with prior art, the beneficial effects of the utility model are: cancelled the operation of the converter tapping amount being read, calculate, writing down by manually, avoided the influence of human factor to converter tapping amount error, alleviated operating personnel's working strength, system's stable and reliable operation has effectively improved the automaticity and the control accuracy of steelmaking system.

Description of drawings

Fig. 1 is a kind of converter tapping amount of the utility model automated collection systems structured flowchart.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described further:

See Fig. 1, a kind of converter tapping amount automated collection systems, comprise slack tank crane, heavy jar crane, converter PLC controller, controlled stage computing machine and management level computer, on slack tank crane and the heavy jar crane contraposition limit switch and transmitting set are set respectively, the contraposition limit switch, be meant when slack tank crane or a heavy jar of crane are walked to walk to downward seats jar position or made progress the cage position, a kind of electric switch amount signal can be provided and this electric signal is sent to device in the converter PLC controller; Transmitting set is meant and the weight signal that the crane weighing device shows can be carried out emitter with the form of radio signal; Radio receiver and tap computing module are set in the converter PLC controller, radio receiver is meant to receive slack tank crane, the heavy jar of crane weight signal that the crane wireless transmitter sends and be stored as in the converter PLC controller device of crane weight signal in the tap computing module; The tap communication module is set in the controlled stage computing machine, the calculating tapping value of tap computing module is gathered automatically.The tap computing module is meant that using contraposition limit signal and crane weight signal to carry out the calculating of slack tank weight calculates and result of calculation is saved in the tap communication data table with heavy jar weight;

Described controlled stage computing machine after heavy jar of crane weight identification with the tap communication data with jar number send to management level computer with telegraph text form in the lump, jar number specify by management level computer.Tap communication module in the controlled stage computing machine, be meant by some cycles the tap communication data table scanned that the molten steel jar that tap communication data table and management level computer is sent to the controlled stage computing machine after heavy jar of weight identification is finished number sends to management level computer with telegraph text form in the lump.

In the enforcement, the weighing device of crane is defined as follows, to guarantee accurate measurement:

Slack tank weight is calculated, be meant when the contraposition limit switch signal of slack tank crane come and crane weight greater than minimum slack tank weight (80-130 ton) and certain time when (10-60 second), mean value in a period of time of crane weight signal that will be corresponding with it or weight signal (3-15 second mean value) is stored as the slack tank weight of tap communication data table;

Heavy jar weight is calculated, be meant that contraposition limit switch signal when heavy jar of crane comes and crane weight greater than minimum heavy jar of weight (300-400 ton) and stablize certain hour when (10-60 second), mean value in a period of time of crane weight signal that will be corresponding with it or weight signal (3-15 second mean value) is stored as the heavy jar weight of tap communication data table.
