Abstract

The utility model discloses a cooling device for a roller, which comprises a spray nozzle 1, a direct electromagnetic drive valve 6, a spray beam 2, a connecting seat 3 and a connecting plate 4, wherein the spray nozzle 1 and the direct electromagnetic drive valve 6 are fixed into a whole and fixedly arranged on the spray beam 2; the spray beam 2 is arranged on an upper working roll 8 and a lower working roll 9 and on the left and right sides of an upper supporting roll 10, and is arranged on the connecting seat 3; the connecting seat 3 is fixedly connected to the connecting plate 4; and the connecting plate 4 is locked on the side of a rolling mill gateway 5. When the cooling device is used, the problem of undesirable cooling effect on the 'hot point' of the body of the roller and on the overall roller body is solved, the service life of the roller is prolonged, the maintenance and repair cost is reduced, costly downtime is reduced, strips with clean surface can be produced, and the surface quality is further enhanced.

Description

A kind of roll cooling device

Technical field

The utility model belongs to the copper processing technique field, particularly belongs to this technical field of roll cooling device.

Background technology

In the operation of rolling of copper coin band,, thereby cause that this part roll diameter of roller increases because the roll barrel temperature is uneven and asymmetrical rolling load can cause " focus " on the roll.The inhomogeneous meeting of roll diameter of roller causes stocking glacing flatness variation, and then the quality of product is produced in influence.

In addition, at room temperature rolling is because distortion heat can make roller temperature raise with frictional heat; Especially more obvious under the high-speed rolling situation; The too high meeting of roll temperature makes the roller quenching layer that the tissue decomposition take place, and makes roll surface additional stress occur, and makes the roll roll surface produce be full of cracks; Simultaneously, the roller temperature height also can make normal roll shape destroyed.Make the rolled products template bad.Roller temperature is too high also can to make lubricant failure.Present body of roll cooling system is undesirable to the body of roll " focus " and the whole cooling effect of the body of roll, is prone to cause the generation of the problems referred to above.

The utility model content

To the deficiency of prior art, the utility model technical problem to be solved provides a kind of roll cooling device, avoids roll because of too high rolled strip quality problems that cause of temperature in the course of the work.

For addressing the above problem, the technical scheme of the utility model is:

A kind of roll cooling device; Comprise nozzle 1, direct Electromagnetically driven valve 6, spray beam 2, Connection Block 3 and connecting plate 4; The fixing as a whole and stationary arrangement of nozzle 1 and direct Electromagnetically driven valve 6 is on spray beam 2; Spray beam 2 is positioned at the upper and

lower working roll

8,9 and top backing up roll 10 left and right sides and is installed on the Connection Block 3, and Connection Block 3 is fixedly connected on the connecting plate 4, and connecting plate 4 is locked in mill housing 5 sides.All corresponding up and down setting of each two row's nozzle 1 on the spray beam 2 of said upper and

lower working roll

8,9 both sides; Nozzle near milled sheet is straight type nozzle 11; Nozzle away from milled sheet is oblique type nozzle 12, and the spray angle of said oblique type nozzle 12 is 45 ° with respect to milled sheet; The jet hole 7 of said nozzle 1 is shaped as spindle; Every row's nozzle on the said spray beam 2 is 12 and evenly distributes; Described direct Electromagnetically driven valve 6 is the integral structure that magnetic valve and injection valve connect together.

Spray beam 2 top nozzles 1 " are cut apart that " become section one by one, each section accurately sprayed up cooling fluid by the nozzle 1 of band valve control, and the injection of each section can be controlled independently to roll barrel; Can touch the button and manually control, can use the PLC semiautomatic control, also can realize Automatic Control through being connected with template control system; And can regulate the injection flow of the section of roll different parts, and correctly apply cooling fluid, reduce rolling load; Improve mill speed and increase drafts, the body of roll " focus " is carried out emphasis accurately cool off, the cooling situation that the balance body of roll is whole; Increase the service life of roll, reduced the maintenance and repair expense, shortened arm and a leg downtime; And help producing the cleaner band in surface, surface quality is further improved.The problem that the cooling fluid of spray beam 2 outflows is gone up in the design of the spindle of jet hole, the water hammer that has solved cooling fluid when control valve opens and closes during with valve-off, and has improved the cooling effect of cooling fluid; The direct integral structure of Electromagnetically driven valve 6 has strengthened the response speed of piston.

Description of drawings

Do detailed explanation below in conjunction with the accompanying drawing specific embodiments of the invention.

Accompanying drawing 1: the structural representation of roll cooling device

Accompanying drawing 2: the course of work sketch map of roll cooling device

Accompanying drawing 3: oblique type structure of nozzle sketch map

Among the figure: 1, nozzle; 2, spray beam; 3, Connection Block; 4, connecting plate; 5, mill housing; 6, direct Electromagnetically driven valve; 7, jet hole; 8, top working roll; 9, bottom working roll; 10, top backing up roll; 11, straight type nozzle; 12, oblique type nozzle.

The specific embodiment

Like Fig. 1, Fig. 2, shown in Figure 3; A kind of roll cooling device; Comprise nozzle 1, directly Electromagnetically driven valve 6, spray beam 2, Connection Block 3 and connecting plate 4, the fixing as a whole and stationary arrangement of nozzle 1 and direct Electromagnetically driven valve 6 is on spray beam 2, and spray beam 2 is positioned at the upper and

lower working roll

8,9 and top backing up roll 10 left and right sides and is installed on the Connection Block 3; Connection Block 3 is fixedly connected on the connecting plate 4, and connecting plate 4 is locked in mill housing 5 sides.All corresponding up and down setting of each two row's nozzle 1 on the spray beam 2 of said upper and

lower working roll

The cooling of roll with lubricated be to realize through the nozzle 1 that is contained on the six roots of sensation jet beam 2 (right entry, each three jet beam of left entry) on right entry, the left entry device left and right sides frame.

On upper and
