Description
Technical Field
The utility model relates to the technical field of metallurgical equipment, in particular to a roller cooling device.
Background
The roll of the cold rolling mill can generate heat in a working state, and the heat can cause a certain deformation of the working roll and the supporting roll, thereby influencing the rolling precision of the rolling mill and reducing the yield of products.
Therefore, how to eliminate the influence of the temperature rise of the working environment of the roller and reduce the rolling defects becomes a technical problem to be solved.
SUMMERY OF THE UTILITY MODEL
Aiming at the problems, the utility model provides a roller cooling device which can effectively cool a roller and improve the processing yield.
The technical scheme of the utility model is as follows:
a roll cooling device for cooling a pair of work rolls and a pair of backup rolls of a rolling mill,
the cooling device is arranged on the frame of the rolling mill;
the cooling device comprises an upper nozzle group and a lower nozzle group which are used for spraying cooling liquid;
the upper nozzle group comprises an upper support roller nozzle group with nozzles facing the upper support roller and an upper working roller nozzle group with nozzles facing the upper working roller;
the nozzles of the lower nozzle group face the lower working roll.
The upper nozzle group comprises a plurality of rows of nozzles which are arranged up and down, wherein at least one row of nozzles is an upper support roller nozzle group.
The upper supporting roller nozzle group is positioned above the upper working roller nozzle group.
The water outlet direction of the upper support roller nozzle group is intersected or tangent with the upper support roller.
According to the roller cooling device, the nozzles are arranged to spray cooling liquid to the working roller and the supporting roller to cool the roller, so that heat generated by the roller can be led out in time, the roller is prevented from deforming due to high temperature and rolling defects caused by the deformation are avoided, cooling protection of the roller is finally realized, and the rolling yield is improved.
Specifically, the upper nozzle group includes an upper support roller nozzle group for cooling the upper support roller and an upper work roller nozzle group for cooling the upper work roller; the lower nozzle group directly sprays cooling liquid towards the lower working roll, and the cooling of the lower support roll is realized by taking the cooling liquid to the lower support roll through the rotation of the lower working roll.
Drawings
Figure 1 is a schematic view of the structure of the present invention,
fig. 2 is a front view of the present invention.
In the figure: 1 is a frame; 2 is an upper nozzle group, 21 is an upper support roller nozzle group, and 22 is an upper work roller nozzle group; 3 is a lower nozzle group; 41 is an upper support roller, 42 is a lower support roller; reference numeral 51 denotes an upper work roll, and 52 denotes a lower work roll.
Detailed Description
The utility model is further described below with reference to FIGS. 1-2.
The cooling device of the roller is used for cooling a pair of working rollers and a pair of supporting rollers of the rolling mill, and the roller specifically comprises an upper working roller 51, a lower working roller 52, an upper supporting roller 41 and a lower supporting roller 42;
the cooling device is arranged on a frame 1 of the rolling mill;
the cooling device comprises an upper nozzle group 2 and a lower nozzle group 3 for spraying cooling liquid;
the upper nozzle group 2 includes an upper support roller nozzle group 21 having nozzles directed toward the upper support roller 41, and an upper work roller nozzle group 22 having nozzles directed toward the upper work roller 51;
the nozzles of the lower nozzle group 3 face the lower work roll 52, the cooling liquid is sprayed to the lower work roll 52, the lower work roll 52 is cooled firstly, and then the cooling liquid is transferred to the lower support roll 42 through the rotation of the lower work roll 52 to cool the lower support roll 42.
The upper nozzle group 2 includes a plurality of rows of nozzles arranged up and down, at least one of which is an upper support roller nozzle group 21.
The upper support roller nozzle group 21 is located above the upper work roller nozzle group 22.
The water outlet direction of the upper support roller nozzle group 21 is intersected or tangent with the upper support roller 41, so that the cooling liquid can fully contact the upper support roller 42 to effectively cool the upper support roller.
