Abstract
The utility model belongs to the technical field of the roll technique and specifically relates to a cooling type roll is related to, locate the outer outer collars of dabber including dabber and cover, dabber and outer collars fixed connection, the water inlet has been seted up to the one end of dabber, the other end of dabber is equipped with the delivery port, be equipped with annular cooling cavity between dabber and the outer collars, water inlet and delivery port all communicate with the cold cavity of annular, be provided with the stock solution chamber in the dabber, stock solution chamber and water inlet intercommunication, the global multirow limbers that is equipped with of stock solution intracavity, limbers and annular cooling cavity intercommunication, every row of limbers gradually becomes close by the water inlet to the delivery port direction at the spindle, the utility model discloses the cooling effect is good, and the cooling is even, simple structure.
Description
Technical field
The utility model relates to roll technology field, especially relates to a kind of cooling type roll.
Background technology
Roll is the important process equipment of Rolling production, roll rolipass design is link important in steel rolling process, in the hot rolling, directly contact with steel during roll work and produce sliding friction, the temperature of roll is very high, need cooling in time, existing cooling effect of roller is poor, and roll rolipass design is uneven, groove serious wear, single groove steel transportation amount is very low, even produces high temperature adhesion, roll loses flesh and the phenomenon such as roll breakage; Simultaneously inadequate at cooling width, easily there is thermal stress damage in pass edge, and not only roller consumption is high, and production cost increases, and also seriously reduces product surface quality, makes the performance of enterprises impaired.
Utility model content
The technical problems to be solved in the utility model is: the problem that existing cooling effect of roller is poor in order to solve, inhomogeneous cooling is even, now provides a kind of cooling type roll.
The utility model solves the technical scheme that its technical problem adopts: a kind of cooling type roll, comprise mandrel and be sheathed on the outer collars outside mandrel, described mandrel is fixedly connected with described outer collars, one end of described mandrel offers water inlet, the other end of described mandrel is provided with delivery port, annular cooling cavities is provided with between described mandrel and described outer collars, described water inlet and delivery port are all communicated with the cold cavity of described annular, liquid storage cylinder is offered in described mandrel, described liquid storage cylinder is communicated with water inlet, described liquid storage cylinder inner peripheral surface is provided with arranges limbers more, described limbers is communicated with described annular cooling cavities, often arrange limbers and become close by water inlet gradually to delivery port direction on mandrel, operationally, water inlet is accessed cooling water, a part of water flows into annular cooling cavities, another part water flows in liquid storage cylinder, annular cooling cavities in water by water inlet to delivery port heating gradually, again because the axial spacing between adjacent two limbers of liquid storage cylinder shortens gradually, when water is the closer to delivery port, water in water in liquid storage cylinder and annular cooling cavities alternately helps annular cooling cavities to cool, water in last annular cooling cavities flows out from delivery port.
Annular cooling cavities is flowed into along water (flow) direction more smoothly in order to enable the water in liquid storage cylinder, further, described limbers axially tilts along described mandrel, open to delivery port because outlet pass incline direction from inside to outside shows as, the water in liquid storage cylinder can better flow in annular cooling cavities along current.
In order to reduce the erosive wear of current breaker roll, further, described delivery port and described annular cooling cavities junction are circular arc, because delivery port and described annular cooling cavities junction are circular arc, the mouth of a river is just flowed out along circular arc, reduces the erosive wear of current breaker roll.
The beneficial effects of the utility model are: the utility model cooling type roll operationally, on mandrel by adjacent two limbers from water inlet to delivery port direction between axial spacing shorten gradually, when the water in annular cooling cavities is the closer to warmmer during delivery port, water in liquid storage cylinder just can be better help annular cooling cavities in water cool, because delivery port and annular cooling cavities junction are circular arc, water flows out along circular arc, reduce the erosive wear of current breaker roll, the utility model good cooling results, evenly, structure is simple in cooling.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 2 is the left view of the utility model cooling type roll;
In figure: 1, mandrel, 2, outer collars, 3, water inlet, 4, delivery port, 5, annular cooling cavities, 6, liquid storage cylinder, 7, limbers.
Detailed description of the invention
The utility model is described in more detail by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
Embodiment 1
As shown in Figure 1, a kind of cooling type roll, the outer collars 2 comprising mandrel 1 and be sheathed on outside mandrel 1, described mandrel 1 is fixedly connected with described outer collars 2;
As shown in Figure 2, one end of described mandrel 1 offers water inlet 3, the other end of described mandrel 1 is provided with delivery port 4, described delivery port 4 is circular arc with described annular cooling cavities 5 junction, annular cooling cavities 5 is provided with between described mandrel 1 and described outer collars 2, described water inlet 3 is communicated with the cold cavity 5 of delivery port 4 and described annular, liquid storage cylinder 6 is provided with in described mandrel 1, described liquid storage cylinder 6 is communicated with water inlet 3, described liquid storage cylinder 6 inner peripheral surface is provided with many row limbers 7, described limbers 7 axially tilts along described mandrel 1, described limbers 7 is communicated with described annular cooling cavities 5, often arrange limbers 7 and become close by water inlet 3 gradually to delivery port 4 direction on mandrel 1.
Above-mentioned cooling type roll, first delivery port 4 is blocked and the water in liquid storage cylinder 6 is full of, in the work of startup roll, the water of roll enters annular cooling cavities 5 by a part of water of water inlet 3, another part water enters liquid storage cylinder 6, water in annular cooling cavities 5 is warmmer the closer to delivery port 4, because liquid storage cylinder 6 has with annular cooling cavities 5 limbers 7 be communicated with, and the axial spacing between adjacent two limbers 7 of liquid storage cylinder 6 shortens gradually, water in help annular cooling cavities 5 that can be more enough and the water coke slurry in liquid storage cylinder 6 cool, thus reach the cooling of breaker roll entirety, because delivery port 4 and described annular cooling cavities 5 junction are circular arc, the mouth of a river is just flowed out along circular arc, reduce the erosive wear of current breaker roll, water in last annular cooling cavities 5 and the water in liquid storage cylinder 6 are flowed out by delivery port 4.
Above-mentioned is enlightenment according to desirable embodiment of the present utility model, and by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
