Description
Technical field
This utility model is related to hot rolling thin strip processing technique field, and in particular to one kind is taken into account improves hot rolling thin strip table
The continuous-output machine group of face quality and plate shape.
Background technology
Traditional hot-strip pickling unit is mainly by the first uncoiler 1, entry loop 2, withdrawal straightening machine 3, descaling bath 4, drift
Washing trough 5, outlet looping 6, the coiling machine 8 of polishing machine 7 and first are constituted, as shown in figure 1, hot-strip is by the uncoiling of the first uncoiler 1
Afterwards, the alternating bending of bending roll 9 in Jing withdrawal straightening machines 3 makes the cracking of belt steel surface oxide skin, crushes（The process is scale breading process）,
Then the strip steel after flexural deformation is aligned by the smoothing roll 10 in withdrawal straightening machine 3, then sequentially enters the pickling of descaling bath 4 and drift
Washing trough 5 is rinsed, and to remove belt steel surface oxide skin and surface residue, Jing polishing machines 7 carry out even surface roughness with after
Process, finally batched by the first coiling machine 8.
In the process program, strip surface quality is mainly imitated by the scale breading effect and follow-up pickling of withdrawal straightening machine bending roll
What rate was determined, the improvement of belt plate shape then depends on the bending straightening of the bending roll and smoothing roll of withdrawal straightening machine to strip steel.Due to band
Steel is thinner, is more difficult to plastic elongation, and its plate shape is also more difficult to control to, therefore when hot-strip is relatively thin（Thickness be 1 ~
1.5mm）When, withdrawal straightening machine bending roll need to carry out heavy reduction bending to it and can be only achieved enough strip steel elongation percentage, so as to obtain
Preferable scale breading effect, and the process is often to sacrifice belt plate shape as cost, depend merely on the follow-up smoothing roll of withdrawal straightening machine not
The strip steel aligning that plate shape deteriorates can be made.And it is very thin to work as hot-strip（Thickness is less than 1mm）When, even if the now bending roll of withdrawal straightening machine
Enough strip steel elongation percentage cannot be also provided to the bending of strip steel heavy reduction so that belt steel surface oxide skin can not be crushed fully,
Cause the acid solution in follow-up acid cleaning process fast and effeciently to penetrate in oxide skin crack to react with oxide layer, pickling
Efficiency is low, and belt steel surface still remains a large amount of oxide skins after so rinsing, and strip surface quality cannot improve.
As can be seen here, when hot-strip is relatively thin（Thickness is 1 ~ 1.5mm）When, traditional pickling unit can only improve strip steel table
Face quality, it is impossible to ensure good belt plate shape；And it is very thin to work as hot-strip（Thickness is less than 1mm）When, strip surface quality and
Plate shape can not be effectively improved.Therefore, it is necessary to improve to prior art.
