Re-start threading；EPC steel edge portion deviation-rectifying system puts into operation strip tension is less when and also results in strip steel and batching
Produce at machine mandrel and relatively slide, produce staggered floor.
On the one hand the staggered floor of coil of strip internal layer can affect follow-up packaging, and staggered floor too seriously just cannot be packed, and especially advises in thickness
When lattice strip steel produces, owing to belt steel thickness is the biggest, it is impossible to staggered floor coil of strip is carried out further following process process, can only regard
Waste disposal, adds production cost；On the other hand serious due to the staggered floor of coil of strip internal layer, when mandrel for recoiling machine shrinks, interior
Layer strip steel mandrel reel is loosened gap irregularly cause internal layer strip steel easily to produce strip steel when coiling machine unloads volume loosing core, nothing
Method unloads volume, processes overlong time and causes outlet looping completely to overlap, and production line stops, and has a strong impact on the rhythm of production and of hot galvanizing line
Level product rate；The most also increase the loss of outlet coiling machine area equipment, reduce the service life of equipment.
Summary of the invention
The technical problem to be solved is to provide a kind of control method preventing heavy gauge steel strip from batching staggered floor, can
