Description
Technical field
The invention belongs to equipment of hot rolling field more particularly to a kind of Novel hot-rolled coiler mandrels.
Background technology
Hot rolling coiler is widely used in the coiling process of strip, makes coiled strip convenient for storage and transport.Mesh
It is preceding that be widely used in national major steel mill is the reeling tube of reeling without interior water cooling.Such coiler mandrel is in strip
After unloading volume, pressure cooling is carried out by external spray system, since the hot-strip temperature batched is very high, such pressure cooling
Mode be not to the cooling effect of the fanning strip of this kind of coiler mandrel, hollow spindle and other key components and parts it is highly desirable,
The service life and production efficiency of reel will be greatly reduced in this way.
107081349 A of Chinese invention patent specification CN disclose a kind of hot rolling coiler cooling system, the cooling system
System is water cooling all the way to be increased inside fanning strip, and the cycle for realizing cooling water is connected by hose, and such design is certain
The cooling effect of fanning strip is played in degree.But since the inner part drilling in fanning strip recycles water hole, this not only adds add
The difficulty of work and process-cycle, but also greatly weaken the intensity of fanning strip.As the sector being in direct contact with hot strip steel
Plate due to being easy to be deformed under the action of alternating hot and cold stress and strip tension, or even can be broken and lead to great peace
Full accident.
Chinese invention patent specification CN201310135872.4 discloses a kind of hot rolling coiler volume using interior water cooling
Cylinder, the reel have equally disposed feed feeder in the endpiece of spool shaft, and the centre of feed feeder is equipped with annular supply flume and annular is let out
Sink, annular water tank are connected with the cooling water hole in spool shaft, and supply flume is connected with inlet opening, and the reel is due in reel
It is provided with cooling water hole inside axis, certain effect, but the fan due to being in direct contact high temperature strip are played to the cooling of reel
Shape plate does not have cooling water hole, fanning strip high temperature can only be passed to the hollow spindle with internal water cooling by heat transfer, because
Fanning strip heat dissipation that this is in direct contact high temperature is slow, and cooling effect is less desirable, still influences making for fanning strip or even reel
With the service life, the production efficiency that cannot reduce that increased production cost well.In addition, two kinds of inventions all do not account for fanning strip engagement
Tooth side has cooling water outflow, influences inner ring of steel coil quality.
