Description

A kind of CSP of correction batches the method for Wrapping Roll roll gap precision
Technical field
The present invention relates to hot rolling reeling process control technology, be specifically related to a kind of method that CSP of correction batches Wrapping Roll roll gap precision.
Background technology
The Wrapping Roll of horse steel CSP downcoiler is bending, guide, holddown belt steel head, and being wrapped on mandrel tightly, Mandrel is assisted to expand tensioning strip steel.The strip steel so rolled tightly send roller and mandrel to set up stable tension adding, it is achieved that batch volume smoothly Take.Wrapping Roll is the presetting roll gap of Wrapping Roll to strip steel head Deformation control major influence factors, but in actual production process, Wrapping Roll roll gap is unstable in batching high-speed rotation, frequently results in 1# Wrapping Roll steel-fastening, causes the hot rolling production order and stop Stagnant, produce a large amount of waste product and defective work, seriously constrain CSP production, steady quality.This problem is equal in Ge great steel mill There is process control issues, be also that hot rolling produces the urgent key issue solved.
Summary of the invention
For coiling machine equipment state, the feature of technology controlling and process, it is an object of the invention to provide a kind of correction CSP and batch and help volume The method of roller gap precision, solves Wrapping Roll work roll gap instability problem, effectively solves horse steel CSP Wrapping Roll steel-fastening problem, Improve milling train production stability.Concrete technical scheme is as follows:
A kind of CSP of correction batches the method for Wrapping Roll roll gap precision, comprises the steps:
(1) correction axle diameter size;
(2) correction mandrel pre-expansion diameter;
(3) correction Wrapping Roll deviation.
Further, step (1) uses manual synchronizing axle diameter size.
Further, step (1) includes that step manually uses the installation diameter of tape measure mandrel before 1. installing;And/or step The artificial expansion maximum gauge using tape measure mandrel after rapid 2. installation.
Further, step (2) uses Automated condtrol correction to program mandrel pre-expansion diameter.
Further, step (2) includes that 1. step corrects the concordance of axle diameter change and radar repeater;And/or step 2., after Wrapping Roll automatic Calibration, hand inspection Wrapping Roll roll gap changes.
Further, step (3) farther includes following steps:
(3-1) adjusting speed and the pressure of Wrapping Roll calibration process, after being allowed to demarcate, roll gap changes in the specific deviation range of technology controlling and process In;
(3-2), after Wrapping Roll automatic Calibration terminates, run mandrel and Wrapping Roll maintains specific speed, check the change of Wrapping Roll roll gap, root According to Wrapping Roll operation result, check each Wrapping Roll roll gap drift value;
(3-3) revising Wrapping Roll roll gap, revised roll gap meets default technological requirement.
Step (3-1) checks data according to first and second step, completes in automatic control program.
Hand inspection Wrapping Roll roll gap change in step (3-2).
Exploitation Wrapping Roll roll gap automated procedures module in step (3-3), revises Wrapping Roll roll gap.
Compared with currently available technology, the present invention is effectively improved and batches production stability.In simulation test: according to 2013 Year so far heap steel number of times statistics, monthly can be prevented effectively from and batch Wrapping Roll heap steel 1 time, effectively prevent continuous casting and rolling stop production, Stop watering the most normally opened watering according to each continuous casting and need 120min;The most subnormal opening waters setting up expenses needs 100,000;Heap steel damages every time Lose 4.7 ten thousand yuan;The average rolling rhythm of milling train is that volume 1/3min. can obtain:
(1) steady production generation year benefit:
=120min/3min × 24 ton/volume × 1000 yuan/ton × December/year=11,520,000 yuan
(2) rolling line accident year failure costs:
=1 time/month × December × (100,000+4.7 ten thousand)=176.4 ten thousand
Therefore, so increasing annual value of production benefit: 1152+176.4=1328.4 ten thousand altogether.

Detailed description of the invention
Describing the present invention below according to accompanying drawing, it is a kind of preferred embodiment in numerous embodiments of the present invention. The first step: manual synchronizing axle diameter size:
1. the artificial installation diameter using tape measure mandrel before installing;
2. the artificial expansion maximum gauge using tape measure mandrel after installing.
Second step: Automated condtrol correction to program mandrel pre-expansion diameter:
1. the change of correction axle diameter and the concordance of radar repeater;
2., after Wrapping Roll automatic Calibration, hand inspection Wrapping Roll roll gap changes;
3rd step: correction Wrapping Roll deviation
1. at automatic control program, check data according to first and second step, adjust speed and the pressure of Wrapping Roll calibration process, be allowed to After demarcation, roll gap changes in the specific deviation range of technology controlling and process;
2. after Wrapping Roll automatic Calibration terminates, running mandrel and Wrapping Roll maintains specific speed, hand inspection Wrapping Roll roll gap changes, According to Wrapping Roll operation result, check each Wrapping Roll roll gap drift value;
3. exploitation Wrapping Roll roll gap automated procedures module, revises Wrapping Roll roll gap, and revised roll gap meets specific technological requirement.
Wherein, artificial check axle diameter size, its control accuracy meets Fig. 3 technological requirement.Check Wrapping Roll zero reference roll gap Meet the technology requirement of Fig. 4.
After New technical use, hot rolling reeling heap steel is greatly reduced, and is effectively improved and batches production stability.In simulation In test: batch the Wrapping Roll steel-fastening number of times average moon 3 times from the second half year in 2013, after measure is implemented, the first half of the year in 2014 Batch the production accident not occurring once to be similar to.
Above in conjunction with accompanying drawing, the present invention is exemplarily described, it is clear that the present invention implements and is not subject to the restrictions described above, As long as have employed method design and the various improvement that carry out of technical scheme of the present invention, or the most improved directly apply to other occasion , all within protection scope of the present invention.
