At present, solution one is the generation taking technical measures to reduce heap steel accident, this method can not reduce the impact after the generation of heap steel accident, another kind method is undertaken judging by the tip position of rolled piece, what calculate is the position of simulating steel billet according to bar rolling speed, if calculating in the normal operation of rolling is more accurately.But when there being other reasons to have impact on bar rolling speed, rolled piece position calculation is just inaccurate.
Summary of the invention
Therefore, the object of the invention is to provide one and can promptly and accurately judges to occur heap steel in the rolled piece operation of rolling, and give the alarm in time and the guard method of the tandem mill stopping milling train running heap steel, described method is:
At the rolled piece entrance side of each frame of tandem mill and rolled piece outlet side, thermometal detecting element is installed respectively, described thermometal detecting element arrives current location for detecting rolled piece tip position, when system judges not arrive rolled piece outlet side in Preset Time after rolled piece termination enters from rolled piece entrance side, start alarm module.
Further, described rolled piece entrance side and rolled piece outlet side respectively install two thermometal detecting elements, with two thermometal detecting elements, rolled piece entrance side all detects that rolled piece termination arrives as confirming that rolled piece tip position arrives the condition of current location, with any one in two thermometal detecting elements, rolled piece outlet side detects that rolled piece termination arrives as confirming that rolled piece tip position arrives the condition of current location.
Further, more than the time of nipping 1 to 2 second of described Preset Time, described in the time of nipping be according to the traveling time of rolled piece in frame determined on the rolled piece biting speed basis of setting.
Further, described alarm module comprises tandem mill functional module out of service and WinCC terminal alarms display module.
Beneficial effect of the present invention is: a kind of tandem mill heap steel of the present invention guard method, ingeniously make use of thermometal detecting element, it is utilized to judge arrival current location, rolled piece termination, by the improvement of rolled piece operation control system control program, promptly and accurately judge in the rolled piece operation of rolling, to occur heap steel, give the alarm in time and stop milling train running, avoid due to the heap damage of steel accident to equipment and the injury to personnel, achieve the security protection of protection to milling equipment and operating personnel, can not judge by accident simultaneously, reliability is high, be suitable for the heap steel protecting control of the various rolled piece of the tandem mill rolling especially easy heap steel rolling piece of heavy rail one class.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the specific embodiment of the invention.
Detailed description of the invention
As shown in Figure 1, milling train comprises UR, E, UF tri-frames, rolled piece is the heavy rail of 60kg/m, the traffic direction of rolled piece shown in Fig. 1 is the rolled piece traffic direction of odd-numbered pass, the rolled piece traffic direction of even-numbered pass is contrary with odd-numbered pass, and rolled piece entrance side and the rolled piece outlet side of each frame install thermometal detecting element respectively.
After three frames nipped by steel billet, perform mill speed generally can not produce and suppress steel accident, just just can produce at Biting Course and suppress steel accident.For strange passage E frame entrance side, control program is stinging steel step, automatic entry condition activates, heavy rail termination enters E frame entrance side and arrives E rack outlet side to utilize thermometal detecting element to judge, calculate its interval time, when rolling heavy rail, the biting speed that operator is arranged is 1.5 meter per seconds, the traveling time of rolled piece in each frame is between 2-3 second, when considering rolling heavy rail, translational speed is a little slow a little, and the traveling time that interlocking judges now is 4 seconds.If the thermometal detecting element of E rack outlet side does not detect that rolled piece arrives yet after 4 seconds, think that E frame entrance side there occurs heap steel accident, activate the alert program of alarm module, the main transmission of UR, E, UF frame stops, and roller-way stops simultaneously.Send accident alarming signal, which position can be shown at WinCC picture and heap steel accident occurs, eject red alarm prompting frame, also can report to the police by display stack steel in warning filing simultaneously.
The protection of odd-numbered pass UF frame entrance side heap steel, even-numbered pass E rack outlet side, even passage E frame entrance side heap steel are protected identical with odd-numbered pass E frame entrance side Method And Principle, and difference is that the detection judgement order of material is different.
In order to ensure the reliability of interlocked control, avoid producing misoperation, at rolled piece entrance side and rolled piece outlet side, two thermometal detecting elements are respectively installed, rolled piece termination enters frame entrance side two thermometal detecting elements and takes the relation of "AND" as decision condition, and rolled piece termination goes out two, rack outlet side thermometal detecting element and takes the relation of "or" as decision condition.
The present invention do not change that former biting speed and mill speed switch condition under, to judge to sting steel switching condition as the condition triggering heap steel program.Be exactly only perform the protection of heap steel at Biting Course.When odd-numbered pass must with Fig. 1 in the action of UF outlet side thermometal detecting element just determine that Biting Course terminates, when even-numbered pass must with Fig. 1 in the action of UR entrance side thermometal detecting element just determine that stinging steel terminates.Thus ensure that odd even passage is all that rolled piece termination has all gone out frame and just determines that Biting Course terminates.
Method of the present invention is in production practices, and by simulating the application of rolled piece and rolled piece in kind, control the interlocking point of transmission operation by PDA control and measuring, system is by PDA and WinCC interface continuous surveillance signal.Accurate judgement can be accomplished to each heap steel accident, and not produce malfunction signal in process, eliminate the impact that heap steel accident causes, saved the production time, reduced mill parts renewal cost, ensure that the personal safety of operating personnel.
