Description
Technical field
The present invention relates to metallurgical technology fields, and in particular to a kind of more furnaces based on electric signal load in mixture plan coalignment
And method.
Background technique
It, need to be heating steel billet to certain temperature, to reduce material deformation before mill milling in iron and steel enterprise's production
Drag.Enterprise generally configures heating furnace before milling train thus, and configuration mode is largely one or more heating furnaces.
As smelter informationization merges the quickenings of paces with automation, heating furnace shove charge plan is by enterprise's three-level
(MES) it is handed down to heating furnace second control system.But since heating furnace there are more, how billet-charging passage is automatically matched to
It is a problem that more furnaces, which are loaded in mixture, in shove charge planning chart.The currently used practice is manually in three-level (MES) or level two
Middle matching by hand, automatization level is low, large labor intensity, and accuracy is poor.
Summary of the invention
To overcome the deficiency, the purpose of the present invention is to provide a kind of, and more furnaces based on electric signal load in mixture plan matching
Device and method is automatically matched to billet-charging passage in shove charge planning chart according to electric signal, realizes that the more furnaces of heating furnace are mixed
Fill the Auto-matching of plan.
The technical solution adopted by the present invention to solve the technical problems is: a kind of more furnaces based on electric signal load in mixture plan
Coalignment, comprising: multiple heating furnaces, charging roller table, three-stage control system, second control system are equipped with before the heating furnace
Charging roller table is set between charging roller table and heating furnace there are two passage, and each heating furnace passage corresponds to a charging roller table section, often
Control is operated alone by motor in a charging roller table section, and motor can positive and backwards rotation；
Each charging roller table section is furnished with locating and detecting device, and locating and detecting device is connected with second control system, by steel billet
Positioning be sent to second control system, be that each charging roller table section increases by two data blocks, number in the second control system
It is set to data block DB1, data block DB2 according to block, wherein storage of the data block DB1 for the mark of steel billet positioning, works as positioning
After the completion, which is set to 1, and is always maintained at, after the completion of heating furnace second control system matches planning chart shove charge passage,
0 is set to by the reset of heating furnace second control system；
The data block DB2 is used for the storage of heating-furnace front roller-way section forward direction and backwards rotation mark, when rotating forward
Rotation mark is assigned a value of 0, and rotation mark is assigned a value of 1 when backwards rotation, and is always maintained at, and heating furnace second control system is to plan
After the completion of the matching of table shove charge passage, 0 is set to by the reset of heating furnace second control system.
A kind of more furnaces based on electric signal load in mixture plan matching process, and the second control system of heating furnace receives three-level control
The shove charge plan of system (MES) transmission processed simultaneously forms shove charge planning chart, and the corresponding flag bit of passage number is assigned a value of n+ in planning chart
1, wherein n is the passage sum of multiple heating furnaces, and the supplied materials direction of steel billet rotates forward direction for roller-way.
1) when heating-furnace front roller-way section rotates forward: if the i-th witness marker assignment 1 of heating furnace, plans
Planning chart first steel billet passage number is come in table in all steel billets of the steel billet passage number greater than (i-1) and is assigned a value of i.
2) when heating-furnace front roller-way section backwards rotation: if 1 assignment 1 of heating furnace, there is mistake in prompt system；
If the i-th witness marker assignment 1 of heating furnace, in planning chart in all steel billets of the steel billet passage number less than or equal to (i-1)
It comes planning chart first steel billet passage number and is assigned a value of i.
The invention has the following advantages: billet-charging passage is automatically matched to shove charge planning chart according to electric signal
In, realize that the more furnaces of heating furnace load in mixture the Auto-matching of plan, matching process of the present invention is simply easily realized, just according only to electric signal
The Auto-matching that the more furnaces of heating furnace load in mixture plan can be realized automatically, mitigate operator's workload, improve heating furnace plan pipe
The automatization level of reason.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
1 heating furnace in figure, 2 heating furnace passages, 3 data block DB2,4 charging roller tables, 41 charging roller table sections, 5 data block DB1.
