Abstract
The invention relates to a control system and method for improving the operation safety of a converter oxygen lance. The system comprises a converter oxygen lance PLC, an oxygen lance lifting height encoder, an oxygen lance lifting motor, an incremental encoder and seven proximity switches. The converter oxygen lance PLC is used for collecting signals of the proximity switches in real time. The proximity switches are distributed in an oxygen lance upper-limit position, an oxygen lance upper working position, an oxygen lance ascending deceleration position 1, an oxygen lance ascending deceleration position 2, an oxygen lance descending deceleration position, an oxygen lance lower working position and an oxygen lance lower-limit position. The operating speed can be accurately limited by acquiring the signals of the proximity switches and signals of the value of the encoder; the numerical value of the lifting height of the converter oxygen lance is corrected in real time through the point of the upper working position and the point of the lower working position; a frequency converter is used for checking the oxygen lance lifting absolute value encoder by acquiring the oxygen lance lifting motor speed increment encoder value, so that the operation safety of the converter oxygen lance is improved, and the situation that an oxygen lance is out of control due to calculated position deviation of the converter oxygen lance lifting encoder is avoided.
Description
Technical field
The invention belongs to pneumatic steelmaking capital equipment oxygen rifle height detection and controlling technology of velocity field, relate to a kind of raising converter oxygen
The control system of rifle safe operation and method.
Background technology
In traditional converter oxygen gun control system, converter oxygen gun height is typically by PLC according to 1 be arranged on after reel
Or 2 absolute value type encoder numerical computations are out, and assist to enter the position of oxygen rifle with cam switch (control switch)
Row location, or use proximity switch as tightly stopping protection in high-low limit position.Below this simple combination control mode exists
Defect:
1, when using master controller, its product attribute is determined that this control accuracy can not be the highest.Master controller sends
Signal is generally detected as an interval range, and in this interval, master controller is with regard to sender, rather than a short pulse signal, because of
Bigger deviation is there is in this in detection position.The most main order controls loosen, to the detection of signal at runtime the most later
Point carrys out deviation, and corrects cumbersome, brings substantial amounts of work to actual operation maintenance.
2, in rotary course, there will be deviation phenomenon due to the encoding up/down device of converter oxygen gun, the most in case of interferers,
The height value calculated with oxygen rifle encoder values due to the speed of oxygen rifle operation also exists a lot of linkage relationships, when oxygen rifle encodes
The value of device in abnormal cases, the properly functioning of oxygen rifle can bring threat greatly.
3, detect, due to the position of oxygen lance lifting, vital effect that the technique of pneumatic steelmaking and safety are played, therefore now with
Use double absolute value type encoder to differentiate the position of oxygen rifle, judge oxygen rifle than single absolute value type encoder to a certain extent
Position is relatively reliable, but this mode passes through routine processes as oxygen than the incremental encoder using existing oxygen rifle velocity measuring
It is higher that rifle height judges have investment, and this encoder is all to be hung in PLC system by fieldbus simultaneously, if network
When breaking down, the value that may result in two encoders all goes wrong, thus it is big inclined to cause oxygen rifle high computational to occur
Difference, the properly functioning of oxygen supply rifle brings adverse influence.
Summary of the invention
In view of this, it is an object of the invention to provide a kind of control system improving converter oxygen lance safe operation and method, use
