Description
Technical field
The utility model is related to cold rolled continuous annealing stove equipment, more particularly to a kind of water cooled rolls.
Background technology
Currently, cold-reduced silicon steel mill continuous annealing unit is divided into preheating section, bringing-up section, is hot-forged and forces cooling section, water cooling
Roller is applied in bringing-up section, and at 1000-1200 DEG C, water cooled rolls plays a supportive role technological requirement temperature in bringing-up section stove.Due to work
Condition inclement condition, water cooled rolls are easy to happen bending or abrasion under the high temperature conditions, on the one hand generate scuffing to strip, on the other hand
Also increase maintenance replacement cost.
The prior art is usually inside water cooled rolls plus a core pipe and is attached to helical blade above, and passes to circulating cooling
Water cools down water cooled rolls, is allowed to work normally under the high temperature conditions.But since water cooled rolls internal helicoid blade is individual blade
Spot welded type, under the impact of vibrated for a long time and cooling circulating water pressure, solder joint is easy cracking, causes part helix blade
Distortion falls off, in addition cooling circulating water long-time fouling inside core pipe, it is easy to cooling water plugging fault occur.
Invention content
To overcome disadvantages described above of the existing technology, the technical problem to be solved by the utility model is to provide one kind
It is wear-resisting, can effectively prevent blocking inside core pipe, the cooling of the water cooled rolls body of roll uniformly, the high water cooled rolls of heat exchange efficiency.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions：A kind of water cooled rolls, packet
Include roll body, rotary joint, water inlet pipe, outlet pipe, core pipe, it is characterised in that：The body of roll of the roll body is internally provided with cooling water channel,
The input end of cooling water channel is equipped with rotary joint A, and outlet end is equipped with rotary joint B；The rotary joint A is connect with water inlet pipe,
Rotary joint B is connect with outlet pipe；The lower section of the outlet pipe is equipped with drain filter；The outlet end of the drain filter with
Return pipe connects；The core pipe is arranged in the body of roll of roll body, and core pipe surface wrap has spiral duct；The body of roll table of the roll body
Face is uniformly coated with overlay cladding.
Preferably：The spiral duct uniform pitch spiral winding is welded in core pipe surface.
Preferably：One end of the spiral duct and the input end connection of cooling water channel, the other end and cooling water channel
Outlet end connects.
The utility model compared with prior art, has the following advantages：
1. by the way that drain filter is arranged, cooling impurities in water and other solid contents are removed, recirculated cooling water is effectively prevent
In magazine dirt block cooling water channel the drawbacks of；
2. welding spiral duct in core pipe surface wrap, the heat exchange efficiency of cooling water is on the one hand improved, the water cooled rolls body of roll is made
Cooling uniformity, improves cooling effect, on the other hand avoids the individual blade of spot welded type because vibratory impulse falls off, cause to cool down
Water channel blocks；
3. overlay cladding is arranged in body surface, under high temperature, steel pipe pressure, rotation friction, it is less prone to cracking, falls off now
As improving the wearability and service life of water cooled rolls.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
In figure：1. water inlet pipe, 2. rotary joint A, 3. core pipes, 4. spiral ducts, 5. cooling water channels, 6. roll bodies, 7. rotations
Adapter B, 8. outlet pipes, 9. drain filters, 10. return pipes, 11. overlay claddings.
Specific implementation mode
The utility model is further described below in conjunction with the accompanying drawings；
In Fig. 1：A kind of water cooled rolls, including roll body 6, rotary joint, water inlet pipe 1, outlet pipe 8, core pipe 3, feature exists
In：The body of roll of the roll body 6 is internally provided with cooling water channel 5, and the input end of cooling water channel 5 is equipped with rotary joint A2, and outlet end is set
There is rotary joint B7；The rotary joint A2 is connect with water inlet pipe 1, and rotary joint B7 is connect with outlet pipe 8；The outlet pipe 8
Lower section be equipped with drain filter 9；The outlet end of the drain filter 9 is connect with return pipe 10；The core pipe 3 is arranged in roller
In the body of roll of body 6,3 surface wrap of core pipe has spiral duct 4；The body surface of the roll body 6 is uniformly coated with overlay cladding 11.
The 4 uniform pitch spiral winding of spiral duct is welded in 3 surface of core pipe.
One end of the spiral duct 4 is connect with the input end of cooling water channel 5, the outlet of the other end and cooling water channel 5
End connection.
When specific implementation：First, cooling water flows through rotary joint A by water inlet pipe, enters back into water cooled rolls body of roll cooling water
Road welds spiral duct in core pipe surface wrap, flows away in this way, cooling water cannot be directly entered outlet pipe, and must be along spiral shell
Rotation conduit slowly flows, and cooling water is made to be come into full contact with the water cooled rolls body of roll, and the water cooled rolls body of roll cools down uniformity, improves cooling
The heat exchange efficiency of water, improves the cooling effect of water cooled rolls, moreover, avoiding the individual blade of spot welded type vibrated for a long time
It falls off with being distorted under the impact of cooling circulating water, cooling water channel is caused to block, flow is unsmooth, and water cooled rolls high temperature is caused to damage；
Drain filter is arranged in the lower section of outlet pipe（Outsourcing finished product）, recirculated cooling water flows through drain filter, cooling impurities in water and
Other solid contents are filtered, and effectively prevent the impurity dirt in recirculated cooling water to block cooling water channel, then cooling water enters
Return pipe；Body surface overlay cladding is formed using H08A welding wire built-up weldings, and the crushing resistance wearability heat resistance of resurfacing welding material compares water
Chilling roller is stronger, and energy effective protection water cooled rolls is less prone to cracking, obscission under high temperature, steel pipe pressure, rotation friction,
Improve the wearability and service life of water cooled rolls.
Above-described embodiment is only intended to clearly illustrate made by the utility model and describes, and not to the limit of embodiment
It is fixed, to those of ordinary skill in the art, other various forms of variations can also be made on the basis of the above description
Or change, there is no necessity and possibility to exhaust all the enbodiments, and the obvious variation thus amplified out
Or among changing still in the scope of protection of the utility model.
