In the process of rolling of a plurality of rolling mills, when one or more rolling mills break down, normal operation of breakdown rolling mills is simulated through a computer so that the rolling mills without breakdowns can conduct rolling operation normally. According to the rolling mill breakdown normality simulating set rolling method, once a position sensor breakdown, a hydraulic breakdown and a transmission system breakdown of a downward pressing system of a certain rack occur in the process of rolling, automatic control can be conducted rapidly, the problem that the rolling mills stop for a long time is solved, and normal hot rolling production is guaranteed.
Description
Technical field
The invention belongs to the control field of hot-continuous-rolling strip steel rolling line, specifically is that a kind of rolling mill fault sky is established milling method.
Background technology
In hot rolling enterprise, leading in the hot finishing process has many hot-rolling mills to carry out hot rolling synchronously, generally must normally to come into operation be rolling primary condition to all hot-rolling mill equipment of finishing mill system, comprise press down system, main transmission etc., but in the operation of rolling, sometimes position sensor and hydraulic fault and the driving unit fault of certain frame press down system occur, caused long-time stopping production, bring enormous economic loss for hot continuous rolling factory.
Summary of the invention
Technical problem to be solved by this invention is: the automatically-controlled continuous that how can the fast processing abnormal conditions in the operation of rolling realizes the hot-rolling finishing mill frame; mutual affirmation problem when how to solve certain frame fault between program and the field apparatus; how to solve the stability between the hot-rolling finishing mill frame, significantly reduce the downtime.
The technical solution adopted in the present invention is: the rolling mill fault sky is established milling method, in many rolling mills operation of rolling, when wherein one or milling train break down, by computer simulation normally the carrying out of milling train of breaking down, thereby make that the milling train that does not break down can normal rolling work.
As a kind of optimal way: according to the different parts that trouble rolling mill breaks down, select the normal operation of these parts of simulation by computer.
As a kind of optimal way: position sensor, hydraulic fault or main transmission fault appear in trouble rolling mill, select the normal operation of these parts of simulation by computer.
As a kind of optimal way: computer simulation has two kinds of analog forms, is that the own rolling mill fault of transmission fault or fault machine is selected analog form according to trouble rolling mill.
The milling train sky is established two kinds of INACTIVE mode and the OUT OF SERVICE modes that are divided into, be exactly position sensor, hydraulic fault or the main transmission fault at certain frame press down system, establish the normal running conditions of mode simulated failure equipment by selecting sky, to satisfy the needed primary condition of belt steel rolling, guarantee under the situation of this fault, also can realize ordinary production.If certain milling train is depressed device systems and is gone wrong, just have influence on actual intermesh determination and detection, it is that milling train can normally be changed trains or buses that motor is not influenced with other equipment, only need lift and depress, select INACTIVE mode sky to establish, can not exert an influence to strip surface quality; If certain milling train can not be changed trains or buses because of electrical fault or bearing shell problem, can only select for use OUT OF SERVICE mode sky to establish, this mode can make in the program simulation milling train condition of changing trains or buses, and satisfies rolling requirement.
The invention has the beneficial effects as follows: the present invention has guaranteed in the operation of rolling in case can implement automatic control fast when the position sensor, hydraulic fault of certain frame press down system and driving unit fault occurring, solved finishing mill and stopped for a long time, it is normal to have guaranteed that hot rolling is produced.
The specific embodiment
The operative employee selects INACTIVE or OUT OF SERVICE function button according to the chassis equipment fault by man-machine dialog interface.After selecting sky to establish frame, this frame hydraulic pressure of computer control depress relief valve get electric, the delivery valve dead electricity, servo valve does not have given, depresses cylinder and lifts, relief valve, delivery valve model: 4WE6D6X/EG24N9K4, servo valve model: 4WSE3EE32-4X/1000B8; For electric fault, this locality/remote control switch is put this locality, be Long-distance Control just often, select during fault local so that sky establish do not influence when frame is handled normally rolling.Various valve controls realize by point-to-point form; Electrified Transmission control realizes by PROFIBUS and GDM communication.
Computer is finished corresponding judgment processing according to selection marker.If select the INACTIVE mode, control program then is set to normal condition (namely being set to FFH by hexadecimal 00H) to the basic interlocking condition of this frame press down system, to satisfy normal rolling condition; If select OUT OF SERVICE mode, control program is then simulated the condition of changing trains or buses of this frame main transmission just the simulation of fault frame is provided normal Velocity Reference (namely Velocity Reference 0m/s being modeled as normal benchmark mill speed), actual speed feedback (namely actual speed feedback 0m/s being modeled as normal feedback mill speed) and transmission duty word (namely hexadecimal CDH being become FFH) etc.By aforesaid operations, then trouble rolling mill is regarded as a normal milling train that does not come into operation and activate, in order to can satisfy normal production conditions fully.
The hydraulic pressure personnel also need to contact back and forth affirmation, just can stop the oil processing fault.
The technical staff need not confirm to force in program, has reduced down time, has solved control and has gone up because of the contact affirmation error that causes not in place.
Computer is established selection marker according to the frame sky, send not activation marker of fault frame down, and finishes the setting calculating of each frame, satisfies ordinary production.
If F2 frame press down system position sensor fault, then the F2 frame does not possess the steel rolling condition, mm finishing mill unit can not steel rolling, in order under the condition of F2 frame fault, to continue steel rolling, the operative employee at first selects the F2inactive push button function from picture, afterwards, computer is finished corresponding judgment processing according to selection marker, put and depress fault condition (as H#FFDC) for normally depressing condition (H#FFFF), this frame hydraulic pressure depress relief valve get electric, the delivery valve dead electricity, servo valve does not have given, depressing cylinder lifts, satisfy rolling requirement, simultaneously second computer is finished down according to selection marker and is sent trouble rolling mill F2 the not setting value of activation marker and other frames, so far, mm finishing mill unit can adopt the F2 frame sky mode of establishing to produce up to the recovery of F2 frame, and the F2 frame withdraws from sky and establishes mode.
The original parking checking of Shanxi Taigang Stainless Steel Co., Ltd, control program need be forced primary condition, confirm correlated condition, afterwards, whether the operative employee needs mould to roll the function of affirmation equipment normal, generally need more than 40 minutes, after selecting this maneuver for use, only needed get final product in 5 minutes, reduced steel scrap simultaneously.Implement 1448.4 ten thousand yuan of the back creations of value.
After using the technical program, effect is as follows:
Realize the automatic control of finishing mill, avoided to greatest extent greatly reducing the rolling line steel scrap because confirming less than the scram that causes, reduced the cancel closedown time.
Setting, the action of having guaranteed the finishing mill system are normal, have solved the long-time parking that causes because of problems such as certain frame faults when rolling, and have avoided the influence to the normal control of subsequent production.
