Detailed description of the invention
Here will illustrate exemplary embodiment in detail, its example represents in the accompanying drawings.When explained below relates to accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawings represents same or analogous key element.Embodiment described in following exemplary embodiment does not represent all embodiments consistent with the present invention.On the contrary, they only with describe in detail in appended claims, the present invention some in terms of the example of consistent apparatus and method.
Fig. 1 is according to a kind of rolled steel production system shown in an exemplary embodiment, and this rolled steel production system includes controller 1, heating furnace 2, roller-way 3, milling train 4, and heating furnace 2 is for heating rolled piece 5, to facilitate milling train 4 to roll rolled piece 5；Roller-way 3 is used for transmitting rolled piece 5.
Milling train 4 is for rolling rolled piece 5, milling train 4 is equipped with chiller, lubricating arrangement, hydraulic means, support means, chiller is for cooling down milling train 4, lubricating arrangement is for being lubricated the change speed gear box of milling train 4, hydraulic means is used for driving milling train 4 to run, support means is for being fixed each device in milling train 4, to prevent milling train from shifting and to prevent the device in milling train 4 from departing from from milling train 4.
Fig. 2 is the flow chart according to a kind of method processing rolled steel production system shown in another exemplary embodiment, and the method is applied in the rolled steel production system shown in Fig. 1, as in figure 2 it is shown, the method comprises the following steps.
In step S101, whether detection rolled steel production system breaks down.
Wherein, can detect whether to receive the fault-signal that the lubricating arrangement of the milling train in rolled steel production system sends, the fault-signal that the chiller of this milling train sends, the fault-signal that the hydraulic means of this milling train sends, and the fault-signal that the support means of this milling train sends.
When the fault-signal that the fault-signal that the lubricating arrangement receiving this milling train sends, the fault-signal that the chiller of this milling train sends, the fault-signal that the hydraulic means of milling train sends, or the support means of this milling train send, determine that rolled steel production system breaks down.Then from the fault-signal that lubricating arrangement sends, the temperature of lubricant in lubricating arrangement is extracted, for the piping flow of pipeline of conveyor lubricant and the loine pressure of this pipeline.
Wherein, the pipeline of lubricating arrangement for flowing to the change speed gear box of milling train by lubricant, and piping flow is the quantity of the lubricant flowing through this pipeline in the unit time, and loine pressure is the pressure to pipeline inner wall of the lubricant in this pipeline.
Under normal circumstances, the temperature of the lubricant in lubricating arrangement, piping flow and loine pressure should be in normal interval.If the temperature of lubricant, piping flow or loine pressure are not in normal interval, it is determined that rolled steel production system breaks down.
Such as, wherein the temperature normal interval of lubricant can be more than 20 and less than or equal to 40, and the normal interval of piping flow can be more than 30 and less than or equal to 45, and the normal interval of loine pressure can be more than 35 and less than or equal to 50.The unit of above-mentioned numerical value is self-defining unit in controller, rather than common standard unit, it addition, these self-defining units can and common standard unit between there is certain proportionate relationship.
When this rolled steel production system breaks down, in step s 102, rolled piece is the most rolled by the milling train in detection rolled steel production system.
When rolled piece is rolled by this milling train, this milling train can control two roll occlusion rolled pieces, generally, when the roll of milling train rolled piece to be engaged, the transporter of milling train must be to the roll the biggest electric current of applying so that roll has the biggest roll-force, and such roll could be engaged rolled piece.Therefore when roll is engaged rolled piece, the roll-force of roll can great changes will take place, now milling train can export according to actuating device and generate current signal to the electric current of roll, and this current signal and/or roll-force signal are sent to controller, controller receives this current signal and/or roll-force signal, judges that rolled piece is the most rolled by milling train according to this current signal and/or roll-force signal.
When rolled piece is rolled by this milling train, in step s 103, control this milling train and continue this rolled piece is rolled, and after this rolled piece is rolled by this milling train, control this milling train out of service.
Wherein, when rolled piece is not rolled by this milling train, then this milling train is controlled out of service.
In the embodiment shown in Fig. 2 of the present invention, whether detection rolled steel production system breaks down；When rolled steel production system breaks down, rolled piece is the most rolled by the milling train in detection rolled steel production system；When rolled piece is rolled by milling train, control milling train and continue rolled piece is rolled；And, after rolled piece is rolled by milling train, control milling train out of service.Compared to cut-out rolled steel production system power supply of the prior art, unexpected power-off can be avoided to make rolled piece rest on milling train interior with the infringement brought to milling train；In addition, the embodiment of the present invention can also continue to roll rolled piece, to avoid rolled piece to become waste product afterwards in resting on milling train, thus avoids wasting resource.
In an alternative embodiment of the invention, when the temperature of lubricant is positioned at the second preset temperature interval, or piping flow is positioned at the second preset flow interval, or loine pressure is positioned at the second preset pressure interval, or when receiving the fault-signal of chiller transmission of milling train, the heating furnace in rolled steel production system can be controlled and stop output rolled piece, and control this milling train continue rolled piece is rolled, after rolled piece is rolled by this milling train, control this milling train out of service, if and along roller-way transmit rolled piece this milling train of direction be not last milling train in rolled steel production system, then control the milling train after being positioned at this milling train to continue rolled piece is rolled, and during rolling, after a complete rolled piece of mill milling, the milling train of the complete rolled piece of controlled rolling is out of service；
Wherein, in embodiments of the present invention, rolled steel production system has multiple milling train and for continuous rolling pattern, i.e. rolled piece only to carry out the rolling of a passage one by one through every milling train and every milling train to rolled piece.
When the temperature of lubricant is positioned at the second preset temperature interval, or piping flow is positioned at the second preset flow interval, or loine pressure is positioned at the second preset pressure interval, or when receiving the fault-signal of chiller transmission of milling train, determine that rolled steel production system breaks down.
Wherein, the second preset temperature interval can be: more than 14 and less than or equal to 17, and more than 43 and less than or equal to 46；Second preset flow interval can be: more than 22 and less than or equal to 26, and more than 49 and less than or equal to 53；Second preset pressure interval can be: more than 25 and less than or equal to 30, and more than 55 and less than or equal to 60.
Even if the temperature of lubricant is positioned at the second preset temperature interval, piping flow is positioned at the second preset flow interval, loine pressure is positioned at the second preset pressure interval and chiller breaks down simultaneously, it also it is minor failure for rolled steel production system, i.e. moment the milling train in rolled steel production system or other equipment will not be caused high risks, such as, will not breaking out of fire or click the situation such as hurt sb.'s feelings.
Therefore, if now rolled piece is rolled by milling train, without cutting off rolled steel production system power supply at once, control the heating furnace in rolled steel production system and stop output rolled piece, the direction of rolled piece is transmitted along roller-way, owing to this rolled piece is rolled by the milling train before this milling train, therefore the milling train that can control before this milling train is out of service, and control this milling train continue rolled piece is rolled, after rolled piece is rolled by this milling train, control this milling train out of service, if and along roller-way transmit rolled piece direction milling train be not last milling train in rolled steel production system, then control the milling train after being positioned at milling train to continue rolled piece is rolled, and during rolling, after a complete rolled piece of mill milling, the milling train of the complete rolled piece of controlled rolling is out of service.
So that the rolled piece rolled can be rolled complete, compared to cut-out rolled steel production system power supply of the prior art, unexpected power-off can be avoided to make rolled piece rest on inside milling train with the infringement brought to milling train；In addition, the embodiment of the present invention can also continue to roll rolled piece, to avoid rolled piece to become waste product afterwards in resting on milling train, thus avoids wasting resource.
If now rolled piece is not rolled by this milling train, but roller-way is transmitting rolled piece, it is not necessary to cutting off rolled steel production system power supply at once, no matter this rolled piece is the most rolled by this milling train, controls the heating furnace in rolled steel production system and stops output rolled piece,
The direction of rolled piece is transmitted along roller-way, owing to this rolled piece is rolled by the milling train before this rolled piece, therefore the milling train that can control before this rolled piece is out of service, and control after this rolled piece milling train and continue this rolled piece is rolled, and during rolling, after a complete rolled piece of mill milling, the milling train of the complete rolled piece of controlled rolling is out of service.So rolled piece can be rolled complete, it is to avoid rolled piece becomes waste product in the operation of rolling, and then avoids wasting resource.
In still another embodiment of the process, when the fault-signal that the fault-signal and/or support means receiving hydraulic means transmission sends, if this milling train carries out multi-pass rolling to rolled piece.Control heating furnace and stop output rolled piece, and the milling train controlling non-rolling rolling stock is out of service, and rolled piece is rolled by control milling train by continuation, when having rolled current pass, controls milling train out of service.
In embodiments of the present invention, rolled steel production system has multiple milling train and for the discontinuous rolling mode of multi-pass, i.e. rolled piece will be the most back and forth continuously across a milling train, and every milling train to be carried out continuously multi-pass rolling to a rolled piece respectively.
Determine that rolled steel production system breaks down when the fault-signal that the fault-signal and/or support means that receive hydraulic means transmission send.Hydraulic means can affect milling train work after breaking down, and owing to vibration can be produced when rolled piece is rolled by milling train, if milling train still works long hours after support means breaks down, then easily lead to the element falling in milling train departs from fixed position and causes milling train.But rolled steel production system can not be caused high risks moment by these faults, will not breaking out of fire or click the situation such as hurt sb.'s feelings, therefore, if now this milling train is carrying out multi-pass rolling to rolled piece, then without cutting off rolled steel production system power supply at once, heating furnace can be controlled and stop output rolled piece, and the milling train that controls non-rolling rolling stock is out of service, and control this milling train rolled piece is rolled by continuation, when this rolled piece has been rolled current pass, control this milling train out of service.
So that the rolled piece rolled can be rolled this passage, compared to cut-out rolled steel production system power supply of the prior art, unexpected power-off can be avoided to make rolled piece rest on milling train interior with the infringement brought to milling train.
If now not having milling train rolled piece to be rolled, controlling heating furnace and stopping output rolled piece, controlling all milling trains in rolled steel production system out of service.
In still another embodiment of the process, when the temperature of lubricant is positioned at the first preset temperature interval, or piping flow is positioned at the first preset flow interval, or loine pressure is when being positioned at the first preset pressure subinterval, control rolled steel production system and send alarm signal, to remind staff that rolled steel production system is checked.
Such as, the first preset temperature interval can be: more than 17 and less than or equal to 20, and more than 40 and less than or equal to 43；First preset flow interval can be: more than 26 and less than or equal to 30, and more than 45 and less than or equal to 49；First preset pressure interval can be: more than 30 and less than or equal to 35, and more than 50 and less than or equal to 55.
When the temperature of lubricant is positioned at the first preset temperature interval, or piping flow is positioned at the first preset flow interval, or loine pressure is when being positioned at the first preset pressure subinterval, determine that rolled steel production system fault belongs to slight fault, now rolled steel production system can still continue to, without cutting off the power supply of rolled steel production system, only need to control rolled steel production system sends alarm signal, to remind staff to check rolled steel production system；Such as control the warning lamp of rolled steel production system send alarm signal and/or control the warning sounder of rolled steel production system and send alarm signal.Now roller-way continues to transmit rolled piece, and milling train continues to roll rolled piece, compared to cut-out rolled steel production system power supply of the prior art, unexpected power-off can be avoided to make rolled piece rest on milling train interior with the infringement brought to milling train；In addition, the embodiment of the present invention can also continue to roll rolled piece, to avoid rolled piece to become waste product afterwards in resting on milling train, thus avoids wasting resource.
Further, during rolled steel production system is checked by technical staff, if it find that rolled steel production system i.e. will appear from catastrophe failure, then need at once rolled steel production system to be keeped in repair, the pre-set button in rolled steel production system can be pressed, when controller receives the pressing operation to pre-set button, then automatically cut off the power supply of rolled steel production system, to avoid getting an electric shock when rolled steel production system is keeped in repair by technical staff.
