Abstract
A kind of autocontrol method of width notcher feed size, belongs to technical field of ferrous metallurgy.Suitable for cold plate band continuous rolling production technology automatic control technology.Width notcher feed distance is measured in width notcher driving equipment installation Linear displacement transducer, in conjunction with preceding working procedure hot rolling flaw labeling, automatic stopping and the accurate control of feed shearing are carried out in fault location, strip edge fault precise ablation may be implemented in this method, improve strip lumber recovery, operator's working strength can also be effectively reduced simultaneously, significantly improve automatization level.
Description
Technical field
The invention discloses a kind of autocontrol methods of accurate control width notcher feed size, belong to Ferrous Metallurgy technology
Field is suitable for cold plate band continuous rolling production technology automatic control technology.
Background technique
During cold plate band continuous rolling, due to hot rolling raw material edge fault, need to shear edge fault, simultaneously
Along with the proposition of flash rolling (not trimming) technology pattern, the number of width notcher edge fault shearing increases therewith, width notcher
Feed size determines the size for shearing discarded crescent moon.Therefore, accurately controlling width notcher feed size is a kind of raising strip
The effective way of lumber recovery.
Under the overall background that country carries forward vigorously industry 4.0 and intelligent plant construction, domestic each iron and steel enterprise increases automatic
The investment of control system reform upgrading.It is according to hot rolling raw material defect number that operator, which operates width notcher shearing edge fault,
According to comparison level-one picture tracking range is sheared after parking manually.Meanwhile only having with light gate control width notcher feed several
Feed size cannot select feed size according to defect size, this has resulted in the serious waste of strip.Existing control method hand
The problems such as dynamic number of operations is excessive, large labor intensity, lumber recovery is low.
Summary of the invention
In order to solve the problems such as labor intensity is big, lumber recovery is low present in above-mentioned width notcher sheared deficit, this hair
It is bright to disclose a kind of autocontrol method of width notcher feed size.Automatic stopping at strip edge fault may be implemented in this method
Accurate shearing, avoids strip from wasting, and improves lumber recovery.At the same time it can also which operator's working strength is effectively reduced, significantly improve certainly
Dynamicization is horizontal.
A kind of autocontrol method of width notcher feed size, this method rate-determining steps are as follows:
Step 1: the side defects of strip steel data that a upper process detects are transmitted and are deposited by production control data platform
It stores up to production line second control system.After the roll bending takes the lead welding, level two is by the multiple defect points of strip away from taking the lead
Distance S1、S2、S3、…SnWith defect away from steel edge portion distance Y1、Y2、Y3、…YnIt is issued to first process control system.
Step 2: welding machine foreboard band takes the lead shear knife number N, every knife shear distance X, strip weld joint tracking length S.It produced
Cheng Zhong, strip speed V at width notcher, when defect point runs to before away from width notcher i.e. S at △ Sn- NX-S < Δ S starts to drop
Speed parking, strip reduction of speed rate are a, are hadThenStep 3: being driven in width notcher two sides
Increase Linear displacement transducer on dynamic device, needs feed distance △ L, Two-stage control system for detecting the accurate sheared deficit of width notcher
System issues plate width L1, width notcher driving side is away from strip center line distance L2, defect is away from steel edge portion distance Y, accuracy compensation
L ', then width notcher needs feed distance,Liquid is sheared to the feed of width notcher driving device, width notcher
Cylinder pressure pressure, shearing complete hydraulic cylinder and lift to retract a series of actions in situ with hydraulic shear driving device and write in PLC SFC sequence
Control program, with defect point tracking in place strip speed reduction of speed to zero be the sequence control program enabling signal, with this sequence
Control EP (end of program) signal plays the entry condition of vehicle as strip on line automatically.According to above-mentioned control principle, entire volume strip is completed
The automatic stopping of multiple defect points, the accurate feed shearing auto-control of width notcher.
The advantages of this method is:
1) defect point automatic stopping at width notcher may be implemented, reduce manual operation, raise labour productivity.
2) according to the accurate feed size of flaw size size, reduce the waste of shearing material strip steel, improve strip at
Material rate.
Specific embodiment
A kind of autocontrol method of width notcher feed size, this method rate-determining steps are as follows:
Step 1: the side defects of strip steel data that a upper process detects are transmitted and are deposited by production control data platform
It stores up to production line second control system.After the roll bending takes the lead welding, level two is by the multiple defect points of strip away from taking the lead
Distance S1、S2、S3、…SnWith defect away from steel edge portion distance Y1、Y2、Y3、…YnIt is issued to first process control system.
Step 2: welding machine foreboard band takes the lead shear knife number N, every knife shear distance X, strip weld joint tracking length S.It produced
Cheng Zhong, strip speed V at width notcher, when defect point runs to before away from width notcher i.e. S at △ Sn- NX-S < Δ S starts to drop
Speed parking, strip reduction of speed rate are a, are hadThen
Step 3: increasing Linear displacement transducer in the driving device of width notcher two sides, accurately cut for detecting width notcher
Incised notch, which is fallen into, needs feed distance △ L, and second control system issues plate width L1, width notcher driving side is away from strip center line distance L2,
Defect is away from steel edge portion distance Y, and accuracy compensation L ', then width notcher needs feed distance,
