Description
Technical field
The present invention relates to a kind of control method of flying shear.
Background technology
Hot rolling technology equipment therefor of the prior art mainly includes：Roughing mill, flying shear and finishing mill.Wherein, roughing mill
For determining the general width and thickness of strip；Flying shear is used to shear strip, and the main purpose of shearing is to ensure strip
Head and tail shape, and reduce and cause harmful effect to working roll roll surface because strip steel head and tail temperature are relatively low；
Finishing mill is used for specific thickness, width and the shape for determining strip, in actual applications, can typically set multiple finishing mills.
The cutter of the operating rolled piece of lateral shear is called flying shear, is a kind of energy fast shut-off iron plate, steel pipe, paper roll
Process equipment, it is metallurgical Steel-rolling Industry, high-speed rod and screw-thread steel shearing machine with fixed length, is the production during modern rolled bar material is cut
Product, there is the characteristics of little power consumption, cost of investment is low.
Existing flying shear typically automatically controls shearing using PLC control program, and its shearing interval time is preset in program,
It can not be modified according to actual conditions so that be possible to miscut occur when performing shearing work to cut, reduce the precision of shearing.
The content of the invention
In view of this, the present invention provides a kind of flying shear control method, passes through closing on so as to control for sensing equipment sensing steel
Flying shear processed performs shearing work, improves shear precision.
To solve above technical problem, the technical scheme is that using a kind of flying shear control method, including following step
Suddenly：
A., thermometer is set between roughing mill and flying shear；The thermometer is connected with flying shear control system；
B., one preset value is set in flying shear control system；
C. the steel temperature signal that thermometer collects relatively is obtained into result A with preset value；And according to result A to flying shear
Send control signal；
D. flying shear performs shear action according to control signal.
As an improvement hot metal detector is set between roughing mill and flying shear；Hot metal detector is detected
As a result B is sent to flying shear control system.
As an improvement flying shear control system contrasts to result A and result B, sent if consistent to flying shear
The signal of shearing, if inconsistent with regard to stopping alarm.
As a kind of further improvement, the preset value is 500 DEG C.
Further improved as another, in step C, if the temperature signal that thermometer collects is more than or waited
In 500 DEG C, 1 is calculated as；If the temperature signal that thermometer collects is less than 500 DEG C, 0 is calculated as.
As an improvement if hot metal detector has detected that steel close on, 1 is calculated as；If hot metal detector
Do not detect that steel close on, and are calculated as 0.
As an improvement described temperature is calculated as pyrometer.
As a preferred embodiment, described hot metal detector model ZYT hot metal detectors.
The present invention is advantageous in that：Flying shear control method with said structure, felt using two class sensors
Steel are answered, and shearing work is performed after two results are compared, the precision of cut piece is substantially increased, avoids because miscut is cut
The economic loss brought, improve the quality of product.
Embodiment
In order that those skilled in the art more fully understands technical scheme, with reference to embodiment
The present invention is described in further detail.
The present invention comprises the following steps.
A., thermometer is set between roughing mill and flying shear；The thermometer is connected with flying shear control system；Roughing mill and fly
Hot metal detector is set between cutting, and hot metal detector is also connected with flying shear control system.Described temperature is calculated as pyrometer.
Described hot metal detector model ZYT hot metal detectors.
B., one preset value is set in flying shear control system；Preset value is 500 DEG C.
C. the steel temperature signal that thermometer collects relatively is obtained into result A with preset value；And according to result A to flying shear
Send control signal；If the temperature signal that thermometer collects is more than or equal to 500 DEG C, 1 is calculated as；If thermometer gathers
The temperature signal arrived is less than 500 DEG C, is calculated as 0.The result B that hot metal detector detects is sent to flying shear control system, such as
Fruit hot metal detector has detected that steel close on, and is calculated as 1；If hot metal detector does not detect that steel close on, and are calculated as
0.Flying shear control system contrasts to result A and result B, the signal of shearing is sent to flying shear if consistent, if differed
Cause with regard to stopping alarm.
D. flying shear performs shear action according to control signal.
Embodiment 1, the steel temperature signal that thermometer collects are 900 DEG C, compare to be more than with 500 DEG C of preset value and preset
Value, is calculated as 1.Hot metal detector has detected that steel close on, and is calculated as 1.Flying shear control system ties two results contrasts, discovery
Fruit is consistent, then sends control signal to flying shear, and flying shear is sheared.
In the present invention, the arriving of steel is detected by two kinds of different sensors, is avoided because extraneous factor is to passing
The influence that sensor is brought, improves accuracy of detection, reduces the probability that miscut is cut.
It the above is only the preferred embodiment of the present invention, it is noted that above-mentioned preferred embodiment is not construed as pair
The limitation of the present invention, protection scope of the present invention should be defined by claim limited range.For the art
For those of ordinary skill, without departing from the spirit and scope of the present invention, some improvements and modifications can also be made, these change
Enter and retouch and also should be regarded as protection scope of the present invention.
