Description
Technical field
The present invention relates to continuous rolling technology field, especially relate to a kind of side guide plate of recoiling machine compress control method.
Background technology
At present, along with client, increasingly stringent, the hot rolling of coils of hot-rolled steel roll quality are produced line and reduced production cost and be subject to
Market environment affects, and factory needs to produce according to order tissue, and small lot, many steel grades, many specifications organize production, thickness simultaneously
Jumping beyond process specifications standard, Limit specifications is constantly expanded.
The function of side guide plate of recoiling machine is that the strip steel head deviateing roller-way center on runout table is directed to volume smoothly
Take machine centrage, send into coiling machine, in the operation of rolling, continue strip steel is guided smoothly centering.
After strip steel head enters pinch roll, transmission side flipper guide holding position controls, and fore side flipper guide is gradually to strip steel
Drawing close clamping strip steel and realize Stress control, during coil, flipper guide keeps constant pressure to be persistently pressed against strip steel, side
Guide plate pressure whether suitable to ensure strip coiling stability and scroll quality most important.Flipper guide pressure is excessive easily to be made
Become thin gauge strip folder drum, if folder drum is serious, easily cause strip steel to fly up under higher coiling speed, cause steel-fastening thing
Therefore, affect steady production；Flipper guide pressure is too small, and flipper guide then can not effectively clamp strip steel, especially heavy gauge steel strip, easily
Cause coil of strip mistake to become serious, affect the processing of client's postorder and use.
Side guide plate of recoiling machine pressure uses constant single Stress control at present, but during actual production, belt steel thickness
Difference, required flipper guide pressure is the most different, during the change of each thickness specification, needs operator's contralateral guidewire in operation screen
Plate pressure is modified.Due to production scene belt steel thickness specification change greatly, rhythm of production soon, need operator frequently to repair
Positive flipper guide Stress control, workload is big, is also unfavorable for producing stable and constant product quality.
