Abstract
This utility model provides roll spray cooling device, belongs to roll production technical field.Motor is driven to be in transmission connection with actively backing roll by belt driver, reductor, chain and sprocket driving device, actively backing roll, driven backing roll are arranged on base by bearing and bearing block, feed pipe is arranged on directly over active backing roll, and feed pipe is provided with two row's atomizers.The total quantity of atomizer is between 2 18, and atomizer is axially uniformly distributed along feed pipe.Atomizer quantity can be opened, it is possible to well control water spray uniformity and intensity so that uniformly, internal crystallization is uniform in roll cooling according to required cooling effect.Actively backing roll both sides are each provided with a driven backing roll one actively backing roll and drive two driven backing rolls rotations, it is possible to achieve carry out the cooling of two rolls simultaneously.This utility model is practical, good in economic efficiency.
Description
Technical field
This utility model relates to a kind of roll heat treatment chiller, especially relates to roll spray cooling device, belongs to
Roll production technical field.
Background technology
Roll is the vitals in steel rolling mill's rolling mill, and material is generally cast steel, through casting or forge, machining,
The processing of the multiple working procedure such as heat treatment, polish just can be finally completed, and the effect of heat treatment is to make high temperature roll by reasonably
Cooling process after in it metal catalysts become bainite, the martensitic structure that hardness is high and wearability is good, so that roll tool
There are enough hardness and good wearability.The method that roll cooling processes has water-cooled, oil is cold, air-cooled, mist is cold, uses water
Quench, oil quenching cooling time, cooling procedure is violent, and the cooling rate difference on roll body surface, roll body core is big, and surface goes out because of fast cooling
Now shrinking, core synchronous can not easily be formed bigger thermal stress and structural stress and cause distortion and crackle, air-cooled cold
But, then having the defect that cooling capacity deficiency, cold wind lack of homogeneity, roller surface are oxidizable, water spray cooling procedure is gentle, roller
Surface, roll body core cooling rate difference little and more higher than air-cooled cooling capacity, but use atomized water spray cooling time, deposit
The defect such as have water spray lack of homogeneity, atomized water spray intensity wayward.To this end, seek the most reasonable water spray chiller
Through becoming exigence.
Summary of the invention
Wayward etc. in order to overcome existing atomized water spray chiller to have water spray lack of homogeneity, atomized water spray intensity
Defect, this utility model provides roll spray cooling device.
This utility model is adopted the technical scheme that by reaching above-mentioned purpose: roll spray cooling device, including driving
Motor (1), belt driver (2), reductor (3), chain and sprocket driving device (4), feed pipe (5), atomizer (6), roll (7),
Driven backing roll (8), base (9), actively backing roll (10), drive motor (1) by belt driver (2), reductor (3),
Chain and sprocket driving device (4) is in transmission connection with actively backing roll (10), actively backing roll (10), driven backing roll (8) by bearing and
Bearing block is arranged on base (9), and feed pipe (5) is arranged on directly over active backing roll, and feed pipe is provided with two fog discharges on (5)
Change shower nozzle (6).
The total quantity of atomizer (6) is between 2-18.
Atomizer (6) is axially uniformly distributed along feed pipe (5).
Actively backing roll (10) both sides are each provided with a driven backing roll (8).
The beneficial effects of the utility model are:
Roll spray cooling device of the present utility model so that the cooling procedure of roll is gentle, thus inside roll not
There will be excessive internal stress, will not scrap because internal stress is uneven cracking, and can be according to required cooling effect
Open atomizer quantity, it is possible to well control water spray uniformity and intensity so that roll cooling uniformly, improves roll
Quality and service life, practical, it is easy to promote, good in economic efficiency.

Actively backing roll (10) is in transmission connection, and actively backing roll (10), driven backing roll (8) are arranged on base by bearing and bearing block
(9), on, feed pipe (5) is arranged on directly over active backing roll, and feed pipe (5) is provided with two row's atomizers (6).Atomization spray
The total quantity of head (6) is between 2-18, and atomizer (6) is axially uniformly distributed along feed pipe (5).Can be according to required cooling
Effect opens atomizer quantity, it is possible to well control water spray uniformity and injection intensity so that roll cooling uniformly, carries
The quality of high roll and service life, actively backing roll (10) both sides are each provided with a driven backing roll (8), an active
Backing roll drives two driven backing rolls to rotate, and can carry out the cooling of two rolls simultaneously.This utility model is practical, easily
In popularization, good in economic efficiency.
Schematically being described this utility model and embodiment thereof above, this description does not has restricted, accompanying drawing
Shown in be also one of embodiment of the present utility model, actual apparatus structure is not limited thereto.So, this area
Those of ordinary skill can also do other changes in this utility model spirit, and these are made according to this utility model spirit certainly
Change, all should be included in the scope required by this utility model.
