Description
Technical field
The invention belongs to Tilting Device of Converter technical field, is related to a kind of converter inclining angle correct control method.
Background technology
Converter inclining angle is typically by PLC to go out turning angle according to encoder numerical computations, in traditional converter control,
Master controller is provided with 0 degree, when setting the signal of master controller as 1, display converter is in 0 degree, passes through this side
Method carrys out the converter angle of check code device calculating.This control mode has the following disadvantages：
First, by the product performance of master controller is determined, the signal that the master controller is sent generally is detected as an area
Between scope, in this section master controller with regard to sender, rather than the pulse signal that a machine is short, therefore detect 0 degree when
Time there may be larger deviation.Rifle blowing requires converter at ± 3 ° under oxygen rifle, if the letter detected due to master controller
Problem number be present and cause under oxygen rifle rifle to encounter converter mouth will occur great security incident.
2nd, because the encoder of converter typically deviation phenomenon can all occur in rotary course, therefore, in converter iron making and
When deslagging, tapping, this angular deviation is to bad influence of keeping the safety in production.
3rd, master controller is because the accuracy of manufacture is there is deviation, in the interval range adjusted, due to main order control
Device follows final drive shaft to rotate and easily produce loosening, so as to cause the signal for being sent to PLC that larger deviation occurs.
The content of the invention
In order to overcome the disadvantages mentioned above of prior art, the present invention provides a kind of converter inclining angle correct control method, it
Correcting device of the master controller as encoder before replacing, so as to reduce the maintenance workload of master controller.
The technical solution adopted for the present invention to solve the technical problems is：A kind of converter inclining angle correct control method,
Its rate-determining steps is：
1st, including converter inclining control PLC, converter inclining angle absolute value type encoder and 5 proximity switches, the 5 of turning angle
Individual proximity switch is arranged on above the turning angle machinery big disk of the non-drive side of converter, and its characteristic distributions is -75 ° of stokehold, -
110 ° with 75 °, 95 ° after Converter and converter at 0 °；And PLC system is directly connected to by way of hardwire, PLC leads to
Cross detect the proximity switches of these systems can be with the more accurate angle for detecting some point of converter inclining；
2nd, converter inclining angular encoder uses the absolute value type encoder of individual pen, is linked into by communication network in PLC system,
Detect encoder encoded radio in real time by network service, the encoded radio collected in real time is converted into converter by conversion program inclines
Dynamic angle value；
3rd, converter inclining PLC obtains converter after 0 ° of proximity switch signal in real time, and one is played to rifle blowing under converter oxygen
The protective effect of the lower rifle of kind safety, its feature are shown as：Because deviation phenomenon occurs in rotation class encoder in rotary course,
If converter physical location calculates the encoder values that make mistake and permitted not in zero-bit because sideslip occurs in converter inclining encoder
Perhaps rifle blows under oxygen rifle, can produce serious damage oxygen rifle accident, by obtaining converter after the signal of 0 ° of zero-bit, with turning
Rifle condition carries out twin check under the judgement oxygen rifle of stove turning angle encoder calculating angle value, is blown so as to improve rifle under oxygen rifle
The security of refining；And converter, can be by the button above HMI to converter after converter zero-bit proximity switch signal is received
The turning angle that fascinates is corrected；
4th, -75 ° of stokehold, 75 ° after -110 ° and stove, 95 ° of proximity switch main functions are what is calculated with turning angle encoder
Angle value conditional parallel controls converter inclining speed；If converter is after " heat starts ", when being run to stokehold direction, inspection
To survey after -75 °, converter inclining speed is forced to low speed, after detecting -110 ° first under " non-converter deslagging " pattern,
Converter will be forced to stop；To stove rear to during operation, after detecting 75 °, converter inclining speed is forced to low speed, in " tapping
Start " after, to stove rear to during operation, detection head will force to stop after measuring 95 ° for converter.Only converter grate handle is again
After secondary back to zero, converter can be continued to run with to operation after stove again.
The positive effect of the present invention is：1st, correcting device of the master controller as encoder before replacing, so as to reduce
The maintenance workload of master controller；
2nd, only increase a kind of supplementary means of 5 proximity switches as converter inclining security control, improve converter inclining operation
Security；
3rd, detecting 0 degree of proximity switch signal, and the value of turning angle encoder deviation within the scope of when, program will
Automatically turning angle is corrected；When 0 degree of the proximity switch signal detected, and the deviation of the value of turning angle encoder
When not within the scope of, it will prompted on HMI, and turn to the encoder correcting button above HMI and carry out turning angle
Correction.
