Description
Technical field
The present invention relates to field of metallurgy, particularly to a kind of roll cooling device and cooling means.
Background technology
Iron and steel is the mainstay of national economy, is the important substance guarantee of national survival and development.Iron and steel produces and includes
The flow processs such as sintering, ironmaking, steel-making, continuous casting, steel rolling, wherein, steel rolling is the extruding making rolled piece pass through roll thus changing shape
Process.Temperature according to rolled piece is distinguished, and Rolling production includes cold rolling and two kinds of hot rolling.During hot rolling, plastic deformation is high, resistance of deformation
Low, make metal change the little energy consuming required for shape, be widely used method when iron and steel produces.
During hot rolling, the rolled piece of high temperature with roll directly contact and produces sliding friction, causes the temperature of roll to raise.Roll
Raise comparatively fast with the spot temperature of rolled piece directly contact, remaining spot temperature raises relatively slowly, and temperature distributing disproportionation is even easily to make roll
Produce uneven thermal expansion, the impact roll thermal crown of roll and the precision of roll gap, thus reducing the quality of steel.Additionally, rolling
Roll temperature is too high also easily to produce security incident, and therefore roll operationally needs to cool down in time.
In prior art, for the screw-thread steel production line generally adopting a pair of cylinder roll, cooling water pipe is arranged at and rolls
Above roller, shower nozzle vertically sprays cooling water, and cooling water is less with the contact area of roller surface, and the shower nozzle above roll is very
The difficult roll that is directed to is sprayed water with rolled piece directly contact position, and cooling effect is poor.Roll cools down not in time, crackle easily, falls block,
Even so that roll wear is accelerated, service life shortens roll breakage etc..
, in use it may be possible to single cavity work is it is also possible to double flute work or multiple-grooved work, its work nest is or not roll
It is fixing, can move along roll surface；Roll in use also due to abrasion and diameter reduce so that roll with cold
But the distance of aqueduct shower nozzle increases.In prior art, cooling water pipe is all directly to weld together with main pipeline, with roll away from
From adjusting, when the work nest of roll converts, cooling water possibly cannot make roller temperature highest part cool down in time.
Additionally, in roll production process, because temperature is higher, one layer of steam blanket can be formed in roll rooved face, shower nozzle with
Roll distance increase when, cooling water reach roll pressure diminish, in order to break through steam blanket it is necessary to increase cooling water pressure and
Flow, this can increase the load to cooling water pressurization and flow control system.
Further, since the cooling water that cooling roll adopts is recirculated water, wherein it is mingled with the impurity such as iron filings, dust, easily
Cause the blocking of shower nozzle, in prior art, because cooling water pipe is welded together with main pipeline, cause nozzle to be difficult to change, or
The nozzle exchange time is longer, reduces production efficiency.
It can be seen that, roll cooling device of the prior art and cooling means, poor to the cooling effect of roll, and be difficult more
Change.
