Abstract
The present invention relates to hot rolling field, is specifically a kind of method for solving hot rolling reeling heavy gauge steel strip reel skidding piling of steel.A kind of method for solving hot rolling reeling heavy gauge steel strip reel skidding piling of steel, in the hot rolling, when coiling machine coiling band steel thickness is more than or equal to 7mm, when reel load relay is connected, plc, which is checked whether, meets the following conditions, reel values for actual speed reel set-point velocity amplitude ＞ 0, reel setting moment values reel actual torque value ＞ 8kNm, the coil wrapper roll Time Delay Opening if all meeting, when reel setting moment values reel actual torque value is less than 1kNm, Wrapping Roll is opened；Meet if not all, normally open Wrapping Roll.The present invention solves the problems, such as the reel skidding piling of steel that hot rolling reeling heavy gauge steel strip easily occurs.
Description
Technical field
The present invention relates to hot rolling field, is specifically a kind of side for solving hot rolling reeling heavy gauge steel strip reel skidding piling of steel
Method.
Background technology
When hot rolling coiler rolls up heavy gauge steel strip, since the small coil ability of reel power itself is low or strip steel head temperature is inclined
Low reason easily causes strip steel head to skid, and Wrapping Roll is automatically opened up still according to former control logic in this case, just
It can cause to batch piling of steel；If setting Wrapping Roll winding strip steel head number of turns increase, it may result in coil of strip and form head tower, constrain
Production is normally carried out.Therefore, batching for normal strip how had not only been ensured, but also think gauge special steel can be solved and made in reel skidding
It is the target that we work into piling of steel problem.
The content of the invention
The technical problems to be solved by the invention are：How the asking of hot rolling reeling heavy gauge steel strip reel skidding piling of steel is solved
Topic.
The technical solution adopted in the present invention is：A kind of side for solving hot rolling reeling heavy gauge steel strip reel skidding piling of steel
Method, in the hot rolling, when coiling machine coiling band steel thickness is more than or equal to 7mm, when reel load relay is connected, plc
Check whether and meet the following conditions
Reel values for actual speed-reel set-point velocity amplitude ＞ 0
Reel sets moment values-reel actual torque value ＞ 8kNm
The coil wrapper roll Time Delay Opening if all meeting, until reel sets moment values-reel actual torque value
During less than 1kNm, Wrapping Roll is opened；Meet if not all, normally open Wrapping Roll.
Reel skids and shows reel values for actual speed and be more than reel set-point velocity amplitude during strip coiling, while reel is set
Determine moment values-reel actual torque value ＞ 8kNm.During the normal coil of coiling machine, in order to ensure scroll is normal, according to batching load
Relay is connected and strip winding number of drum turns（Generally 3~5 circles）Wrapping Roll is opened, coiling machine is set up by strip steel head
Tension force normal volume rounding block strip；Coiling machine strip steel head is when reel skids, if Wrapping Roll is opened according to normal condition,
Then strip piling of steel.For this according to coiling band steel thickness, batch that load relay, spool velocity be poor, reel torque difference determines volume
The control program of machine aided winding up roller Time Delay Opening is taken, so that it is guaranteed that heavy gauge steel strip head is unlikely to piling of steel when reel skids.
The beneficial effects of the invention are as follows：The present invention solves the reel skidding piling of steel that hot rolling reeling heavy gauge steel strip easily occurs
Problem, avoids the rolling line channel blockage caused by batching piling of steel, improves production efficiency, realizes hot rolling coiler and stablizes control
System.
Embodiment
Implementation process of the present invention is entirely to be realized automatically in computer program.Main process is：According to rolled band steel
Thickness, reel load relay connect signal and with steel drum slide condition estimate of situation, automatic real accordingly by primary computer
Existing coil wrapper roll control, meets production control and requires.
Embodiment 1：
When the carbon steel T610L heads that target strip is thickness 7.9mm reach reel, reel load relay is connected, and one
Level computer is by controlling program to calculate the difference of reel values for actual speed and reel given speed value at this time（5.6-5.1=0.5）、
Reel sets the difference of moment values and reel actual torque value（22.8-8.5=14.3 kNm）.Spool velocity difference is more than zero, volume at this time
Cylinder torque deviation is more than 8kNm, meets whole slide conditions, coil wrapper roll Time Delay Opening, and Wrapping Roll helps reel to continue to twine
Around the strip of skidding, it is less than 1kNm until reel sets moment values-reel actual torque value, after reel tension force is normally established, journey
Sequence sends Wrapping Roll and opens order again, it is ensured that batches not piling of steel.
Specific embodiment 2：
When the carbon steel T610L heads that target strip is thickness 10mm reach reel, reel load relay is connected, level-one
Computer is by controlling program to calculate the difference of reel values for actual speed and reel given speed value at this time（4.5-4.2=0.3m/s）、
Reel sets the difference of moment values and reel actual torque value（24.7-12.5=12.2 kNm）.At this time spool velocity difference be more than zero,
Reel torque deviation is more than 8kNm, meets whole slide conditions, coil wrapper roll Time Delay Opening, and Wrapping Roll helps reel to continue
The strip to skid is wound, is less than 1kNm until reel sets moment values-reel actual torque value, after reel tension force is normally established,
Program sends Wrapping Roll and opens order again, it is ensured that batches not piling of steel.
