Technical field
The present invention relates to a kind of automatic detection and the device of protection production line of rolling mill of the automatic detection device and the method, particularly nonferrous metallurgy continuously casting and continuously rolling technology field of a kind of milling train broken string or heap line.
Background technology
Because a lot of subjectivities and objective reason make, copper bar are produced the milling train of continuous casting and rolling production line produces copper rod disconnection and heap line through regular meeting phenomenon.If can not be in time and detect exactly and play a protective role this time, will produce very serious consequence.
In when broken string, if detect untimelyly, can cause a volume copper bar the inside a plurality of copper bar chieftains to occur, thereby influence product quality, this meeting cause great infringement to corporate reputation; When the heap line, as can not in time detecting and protect, can cause the copper bar to be squeezed between roll and the roll stand, thereby cause the breaker bolt fracture, even can occur scrapping roll and the situation that burns out motor.
Summary of the invention
The automatic detection device and the method that the purpose of this invention is to provide a kind of milling train broken string or heap line, it can in time find broken string or heap line, avoids occurring dangerous situation, alleviates operating personnel's monitoring amount.
For this reason, according to an aspect of the present invention, the automatic detection device of a kind of milling train broken string or heap line is provided, has it is characterized in that, in the support of the port of export of finishing mill, be provided with a conducting ring, this conducting ring insulate through insulating materials and support; This support ground connection; This conducting ring is connected with an automatic controller; The internal diameter of this conducting ring is greater than the external diameter of product bar.
Preferably, said conducting ring is that the said product bar of copper ring is the copper bar.
Preferably, the internal diameter of said conducting ring is greater than the external diameter 5-10mm of product bar, preferred 6-8mm.
Preferably, said automatic controller is PLC.
Preferably, said automatic controller is provided with delay time setting and watch-dog, broken string or heap line alarm and/or production line stop protection actuator.
Preferably, also be provided with the pitch sensors that is used for spacing between testing product bar and the conducting ring and/or be used for the relative velocity sensor of testing product bar gait of march.
According to another aspect of the present invention; The automatic testing method of a kind of milling train broken string or heap line is provided; It is characterized in that; At the port of export of finishing mill the conducting ring of a suitable diameter is installed, conducting ring is separated with insulating materials and support, connects a signal entering automatic control system on the conducting ring; Under the ordinary production state, the product bar passes from conducting ring and advances, but keeps spacing with conducting ring; When broken string or heap line took place, the product bar can drop because of broken string or heap line, runs on the conducting ring, and conducting ring is with regard to ground connection, and signal just triggers and enters into automatic controller, on block, carried out the protection aspect safety and the shutdown.
Preferably, the pitch sensors of setting and product bar on conducting ring or pedestal with the spacing between further testing product bar and the conducting ring, when soon the heap line taking place, because of spacing becomes little undesiredly, can be reported to the police in advance.
Preferably, the relative velocity sensor with the product bar is set on conducting ring or pedestal,, when soon broken string taking place,, can reports to the police in advance because of the gait of march of product bar becomes undesired ground slowly with the gait of march of further testing product bar.
Preferably, said conducting ring is a copper ring, and said product bar is the copper bar.
According to the present invention, production line can automatically play and report to the police and protective effect when broken string or heap line occurring, has improved device ' to a great extent, has significantly reduced the operating personnel's workload that causes because of broken string or heap line.
Description of drawings
Fig. 1 is according to milling train broken string of the present invention or piles the principle schematic of the automatic detection device of line in normal operating conditions.
Fig. 2 is according to milling train broken string of the present invention or piles the principle schematic of the automatic detection device of line in the warning duty.
The specific embodiment
Shown in Fig. 1-2; Copper ring 2 is installed in the support 1 of finishing mill, separates with insulating materials 3 and support 1, on copper ring 2, connects a signal power source; When broken string or heap line take place when; Copper ring 2 is with regard to ground connection, and signal just triggers and enters into the PLC the inside, on block, carries out the protection aspect safety and the shutdown.
In one embodiment of the invention, at the port of export of finishing mill the copper ring 2 of a suitable diameter is installed, copper ring 2 usefulness insulating materials 3 are separated with support 1, connect a signal entering automatic control system on the copper ring 2.
In other words, a logic switch K is set between copper ring 2 and automatic controller 4.This logic switch K is off-state under the ordinary production state, only copper bar 5 because of the situation that broken string or heap line and copper ring 2 have taken place comes in contact under, this logic switch K just is in closure state.
Therefore, as shown in Figure 1, under the ordinary production state, copper bar 5 passes from copper ring 2 and advances, but is not in contact with one another with copper ring 2.Therefore, the logic switch 4 between copper ring 2 and the automatic controller 4 is opened, and automatic control system is in the state that detects and wait for.
After broken string or heap line situation occurred, as shown in Figure 2, copper bar 5 can drop because of broken string or heap line, near meet this device the position shown in the Reference numeral 6 copper ring 2.Because copper bar 5 contacts with frame 1, is ground connection; The switch triggering that has also just caused logic switch K; Make logic switch K change closure state into; Thereby the generation triggering signal, and give automatic controller 4, automatic control system can be provided with suitable delay time, produce corresponding the broken string or the police of heap report from a liner, broken string or heap line triggering back production line stop protection etc. in the production status of oneself.
According to the present invention; Automatic control system can be provided with and revise the preset value of response time; Production line can play when broken string or heap line occurring and report to the police and protective effect, has improved device ' to a great extent, has significantly reduced because operating personnel's workload that broken string or heap line cause.
In a further embodiment; Pitch sensors with copper bar 5 can be set on any suitable position of copper ring 2 or pedestal or other; With the spacing between further detection copper bar 5 and the copper ring 2, like this, in when, soon the heap line taking place when; Because of spacing becomes little undesiredly, just can report to the police in advance.Like this, if handle in time, just needn't let production line of rolling mill stop.
In a further embodiment; Relative velocity sensor with copper bar 5 can be set on any suitable position of copper ring 2 or pedestal or other; With the gait of march of further detection copper bar 5, like this, in when, soon broken string taking place when; Because of the gait of march of copper bar 5 becomes undesired ground slowly, just can report to the police in advance.Like this, if handle in time, just needn't let production line of rolling mill stop.
