Description
Technical field
The utility model relates to steel rolling process technical field, particularly finishing mill rack support roller and working roll hot rolling oil system.
Background technology
Along with the development and apply of hot strip steel rolling new technology, and the requirement of user to plate quality is more and more higher, for saving energy and reduce the cost, improving product quality and production efficiency, lubrication in heat-rolling process technology comes into one's own gradually, its obtaining on strip-mill strip is generally applied, and as important technological measure development and perfect in practice.
Existing 1780 hot-rolled strip production lines are made up of two oil supply systems: F1 ~ F3 frame is by system 1 fuel feeding, F4 ~ F7 frame is by system 2 fuel feeding, oil supply system is that working roll sprays hot-rolling oil, the DeGrain played like this, because the wearing and tearing of working roll reduce, but supporting roller abrasion is constant, do not change the surface appearance of backing roll.
Summary of the invention
The utility model, in order to change the uneven state of wearing and tearing, reduces roll-force further, improves roller surface state, improves mechanical property, and for lower step is produced thinner, the more difficult product that rolls is prepared, and provides a kind of new backing roll and working roll hot rolling oil system.
For achieving the above object, the utility model realizes by the following technical solutions:
Finishing mill rack support roller and working roll hot rolling oil system, comprise working roll entrance side and upper and lower hot-rolling oil injection equipment is set, backing roll outlet side arranges upper and lower hot-rolling oil injection equipment, working roll entrance side is all connected with the blender of oil supply system with the hot-rolling oil injection equipment of backing roll outlet side, the hot-rolling oil collector of working roll entrance side hot-rolling oil injection equipment and nozzle are arranged on the inner side of water discharging board, on backing roll outlet side, hot-rolling oil injection equipment arranges hot-rolling oil collector and nozzle, under backing roll outlet side, hot-rolling oil injection equipment arranges down a water discharging board, hot-rolling oil collector and nozzle, prop up down water discharging board and be arranged on gap place between bottom working roll and lower support roll, hot-rolling oil collector and nozzle are arranged on down below a water discharging board.
The nozzle quantity of the upper and lower hot-rolling oil injection equipment of described backing roll outlet side is 18 ~ 20.
The hot-rolling oil that described backing roll outlet side upper and lower hot-rolling oil injection equipment nozzle ejects is injected in more than backing roll center.
Compared with prior art, the beneficial effects of the utility model are:
(1) reduce roll wear, reduce roll unit consumption, extend roll change cycle and rolling scaduled milimeter number, boost productivity.
(2) reduce roll-force, reduce the power consumption of motor, improve the production capacity of milling train, the rolling of more thin gauge strip can be realized.
(3) improve roll surface condition, reduce iron scale press-in, improve strip surface quality, improve the production efficiency of next procedure (as pickling line).
(4) in ferrite rolling process, hot-rolling lubricating can improve the microscopic structure of band steel, improves its mechanical property.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is further illustrated:
As shown in Figure 1, finishing mill rack support roller and working roll hot rolling oil system, comprise working roll entrance side and upper and lower hot-rolling oil injection equipment is set, backing roll outlet side arranges upper and lower hot-rolling oil injection equipment, working roll entrance side is all connected with the blender 1 of oil supply system with the hot-rolling oil injection equipment of backing roll outlet side, the hot hot-rolling oil nozzle 3 of working roll entrance side hot-rolling oil injection equipment is arranged on the inner side of water discharging board 2, on backing roll outlet side, hot-rolling oil injection equipment arranges hot-rolling oil collector 8 and 18 ~ 20 nozzles 9, under backing roll outlet side, hot-rolling oil injection equipment arranges down a water discharging board 10, hot-rolling oil collector 8 and 18 ~ 20 nozzles 9, the hot-rolling oil that nozzle ejects is injected in more than backing roll center.Prop up down water discharging board 10 and be arranged on gap place between bottom working roll 6 and lower support roll 7, hot-rolling oil collector 8 and nozzle 9 are arranged on down below a water discharging board 10, prevent a large amount of hot-rolling oil splash on steel plate.
The application of above-mentioned finishing mill rack support roller and working roll hot rolling oil system, makes the wear extent of work roll surface reduce to 120 ~ 200 μm from every radius 150 ~ 250 μm, and roller consumption can reduce about 20%.
Be only general principle of the present utility model above, not impose any restrictions the utility model, every foundation the utility model carries out equivalent variations and modification to it, all within the category of the art of this patent protection scheme.
