CN201791724U - Guide cut water device for hot-rolling roll - Google Patents

Abstract

The utility model discloses a guide cut water device for a hot-rolling roll, which comprises a guide plate and a cut water plate arranged at the front end of the guide plate. The middle of the cut water plate is provided with a screw hole; and a screw passes through the screw hole so as to fixedly connect the cut water plate and the front end of the guide plate. After one end of the cut water plate is worn, the cut water plate is not needed to be moved forward, the end cut water plate is detached and reversely fixed, and the other end of the cut water plate is continuously used; therefore, the breakage of the cut water plate is avoided, and the service life of the cut water plate is prolonged. In addition, a countersunk head screw is adopted for fixation so as to achieve the effect of preventing the screw head from damaging the roll.

Description

The water device is cut in the guide and guard of roll for hot-rolling

Technical field

The utility model relates to the water-cooled auxiliary equipment of roll for hot-rolling, and more particularly, the water device is cut in the guide and guard that relate to a kind of roll for hot-rolling.

Background technology

Hot-strip production is to carry out under the high temperature about 1000 degree, so the roll of rolled band steel must be used water cooling in the course of the work incessantly.If the breaker roll cooling water is not guided and is controlled, cooling water is in the cooling roll, also can cool off, cause the heating-up temperature of in the hot rolling production process, having to improve the band steel greatly, increase the production cost of energy consumption and enterprise owing to band steel temperature drop to hot-strip.Do not flow on the band steel in rolling in order to control the roll cooling water, see also shown in Figure 1ly, general way is on 1 on roll guide and guard to be installed to cut water device 10 at present, and the guide roll cooling water flows away and do not flow directly on the band steel from the limit portion of roll 1.It is described to see also Fig. 1, and every cover guide and guard are cut water device 10 and included guide plate 11 and be located at water discharging board 12 on guide plate 11 front ends, and water discharging board 12 1 ends have waist-shaped hole 13, and passes waist-shaped hole 13 by holding screw 14 and fix with guide plate 11.Yet flow to for preventing to leak on the band steel, water discharging board 12 other ends need be adjacent to roll 1 surface, so water discharging board 12 in use will wear and tear, and by turning on holding screw 14, water discharging board more than 12 millimeters of reaches and fixing the continuation are used.But discovery after water discharging board 12 spurs forward, fractures in roll 1 knee-action process easily in actual use, thereby has more shortened the service life of water discharging board 12.In addition, because the head of holding screw 14 is higher than water discharging board 12 upper surfaces, therefore when water discharging board 12 wearing and tearing surpass 70mm, screw 14 heads will be run into roll 1, cause roll 1 damage.

The utility model content

At the above-mentioned shortcoming that exists in the prior art, the purpose of this utility model provides a kind of guide and guard of roll for hot-rolling and cuts the water device, in order to the service life of effective prolongation water discharging board.

For achieving the above object, the utility model adopts following technical scheme:

The guide and guard of this roll for hot-rolling are cut the water device and are comprised foreplate and be located at water discharging board on the foreplate front end, and the centre of described water discharging board has screw, and pass screw and the foreplate front end is connected to a fixed by holding screw.

Described screw is the countersunk head screw, and described holding screw is a countersunk head screw.

Water discharging board one end end maintains an equal level mutually with foreplate front end end.

Distance between described screw and the foreplate front end end is 120mm.

In technique scheme, the guide and guard of roll for hot-rolling of the present utility model are cut the water device and are comprised foreplate and be located at water discharging board on the foreplate front end, and the centre of water discharging board has screw, and pass screw and the foreplate front end is connected to a fixed by holding screw.After water discharging board one end wearing and tearing, need not reach, and only need pull down and turn fixing, continue to use its other end, thereby not only avoided the fracture of water discharging board, but also prolonged its service life.In addition, fix, also played the effect that prevents that screw terminal from damaging roll by adopting countersunk head screw.

Fig. 1 is that water Unit Installation position view is cut in the guide and guard of roll for hot-rolling;

Fig. 2 is that water apparatus structure schematic diagram is cut in the guide and guard of prior art;

Fig. 3 is that water apparatus structure schematic diagram is cut in guide and guard of the present utility model;

Fig. 4 is the structural representation after wearing and tearing are all used at water discharging board of the present utility model two.

The specific embodiment

Further specify the technical solution of the utility model below in conjunction with drawings and Examples.

See also shown in Figure 3, it is basic identical with prior art that water device 20 is cut in the guide and guard of roll for hot-rolling of the present utility model, equally also comprise foreplate 21 and the water discharging board of being located on foreplate 21 front ends 22, different is, the centre of water discharging board 22 has screw 23, and passes screw 23 by holding screw 24 and be connected to a fixed with foreplate 21 front ends.Above-mentioned screw 23 is a countersunk head screw 23, and above-mentioned holding screw 24 is a countersunk head screw 24,24 on the screw in back so is installed can not be exceeded water discharging board 22 upper surfaces, can avoid bumping with roll.And these water discharging board 22 1 end ends maintain an equal level mutually with foreplate 21 front end ends, and the distance between its screw 23 and the foreplate 21 front end ends is 120mm.See also shown in Figure 4, in use, after water discharging board 22 1 ends are worn, can be by unloading that holding screw 24 is turned water discharging board 22 and fixing once more, thus can continue to use its other end, change until these end wearing and tearing.

Adopting guide and guard of the present utility model to cut water device 20 has the following advantages:

1, the life cycle of water discharging board 22 obtains prolonging, and utilization rate can bring up to 70% by original 25%, makes contributions for enterprise realizes cost efficiency.

2, help avoiding original water discharging board 22 to use the later stage because wearing and tearing are bigger, holding screw 24 collision roll roll surfaces, and then cause the increase of roll roller consumption and product surface defectives such as scuffing to occur, and the fastening effect of water discharging board 22 also is improved.

3, simple in structure, use and easy for installation helps improving operating efficiency.

Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
