Definitions
- the invention relates to a device for cooling a metal strip between two rolling stands, wherein the tape is guided over a surface-shaped transfer element and below the transfer element, a spray element is arranged, which passes through at least one opening in the transfer element cooling medium to the underside of the belt.
- interstage cooling is used to influence the surface temperature of the strip between the stands.
- the intercooler cooling essentially fulfills two tasks:
- the strip temperature is set as part of the technological process management to adjust certain material properties by applying the tape with the necessary amount of water. This mode of operation applies to all scaffolding.
- the typical quantities of water required vary between about 80 and 280 m 3 / h for interstage cooling when the strip is exposed to water on both sides.
- the water pressure is between 1 and 10 bar.
- EP 0 998 993 B1 provides a combination of an intermediate stand cooling system with an additional roll cooling system. tion in the region of the outlet-side roll gap using a directed pressure water flow along a circumferential region of the roll bale of each work roll before.
- the inter-frame cooling and the roller cooling work each with non-contact seals with respect to the rolling stock or the roll bale.
- EP 1 399 277 B1 discloses a method for cooling and lubricating rolls of a roll stand, in which, for the purpose of economical roll cooling and lubrication, depending on the boundary conditions and requirements, either only lubricant is applied or only one rolling belt cooling is activated.
- EP 1 624 078 A1 has disclosed a device for cooling a sheet-metal strip with nozzles arranged in transverse rows to the direction of tape feed below the strip for a cooling liquid to be sprayed onto the underside of the strip.
- the nozzles designed as flat jet nozzles form a common central jet area per transverse row and that covers in the spray area of the nozzles are provided laterally adjacent to the sheet metal strip.
- WO 2005/115651 A1 discloses a method and a device for cooling or lubricating rolls or rolling stock using cooling medium and base oil.
- the cooling medium is separated from the base oil on the rollers and excluding the base oil without water as the carrier medium in a relative to the usual Amount of very small amount applied directly to the rolling stock over its entire width.
- the lower nozzle bar is located under a transfer table on which the belt to be cooled runs.
- the transfer table has the task of guiding the strip horizontally between an exit guide and a loop.
- the splash water of the lower nozzle bar must be guided through the transfer table.
- the invention is therefore the object of an intercooler cooling of the type mentioned in such a way that a better cooling by creating an improved spray pattern of the band, especially on its underside, is possible, with a more homogeneous cooling over the bandwidth and length to be achieved.
- This object is achieved in that at least two in the direction transverse to the conveying direction of the belt juxtaposed openings are introduced into the transfer element, which - in plan view of the transfer element - have an elongated shape, wherein the longitudinal axis of the opening to the conveying direction of the belt below is aligned at an angle.
- the angle is preferably between 10 ° and 50 °, more preferably between 20 ° and 40 °.
- the openings in the transfer element preferably have a length which is at least twice, preferably at least three times, the width of the openings.
- a plurality of spray nozzles may be arranged in the injection element.
- the transverse extent of the openings is designed in such a way that the front end of an opening in the conveying direction, viewed transversely to the conveying direction of the strip, projects beyond the rear end of the adjacent opening in the conveying direction to the side of the adjacent opening.
- the transfer element is preferably a transfer table known as such; the injection element is advantageously designed as a spray bar.
- Cooling trained cooling device allows a larger loading length of the belt with cooling medium. It is also ensured sufficient coverage in the direction transverse to the conveying or rolling direction of the band, which applies both at low and at high pressure.
- Figure 1 is a side view of a device for cooling a metal strip, which is arranged between two rolling stands.
- Fig. 2 shows the view "A" according to Fig. 1, i.e. the plan view of a transfer table of the device, without representation of a spray bar arranged above the belt;
- a device 1 for cooling a metal strip 2 is shown, which is designed as an intermediate stand cooling. It is arranged between two stands, wherein in Fig. 1, only one of the rolling stands 3 is indicated.
- the belt 2 is guided in the rolling direction or conveying direction F via a transfer table 4 (transfer element), as is known per se.
- a transfer table 4 transfer element
- the upper spray bar 13 sprays the upper side of the strip; Accordingly sprayed the lower spray bar 5, the bottom 8 of the belt 2.
- the spray bars 5 and 13 each have a plurality of spray nozzles 10, which apply the cooling medium 7 (water).
- the rollers 14 form a nip 15, the band 2 passes.
- Scrapers 16, 17 are located behind the rollers 14. Through openings in these guides 16, 17, spray water is sprayed onto the belt surface, originating from an upper or a lower spray bar 18 and 19.
- the spray of the lower spray bar 5 is injected through openings 6 in the transfer table 4 on the belt 2. It is essential that at least two in the direction Q transverse to the conveying direction of the belt 2 juxtaposed openings 6 are introduced into the transfer table 4, which have an elongated shape in the plan view of the transfer table 4, wherein the longitudinal axis 9 of the opening. 6 is aligned to the conveying direction F of the belt at an angle ⁇ . In the exemplary embodiment, the angle is about 30 °.
- FIG. 2 This embodiment is shown in Fig. 2 in more detail.
- the longitudinal axis of the openings 6 is denoted by 9 and extends parallel to the plane of the surface of the transfer table 4 or to the plane of the belt second
- the length L of the openings 6 is significantly greater than the width B; the length L should be at least twice, preferably at least three times
- Width B amount. It can also be seen that the individual openings 6 in
- Cover direction Q transversely to conveying direction F.
- the coverage b is registered for two adjacent openings 6. This can also be seen on the basis of the two openings 6 'and 6 ", which are arranged next to one another and have respective front and rear ends 11 and 12. Projecting at the front At the end 11 of the opening 6 ', the end of the opening in the direction Q, it follows that it is already behind the transverse extent of the adjacent opening 6 "in the rear end portion 12. This means that a complete transverse overlap of the spraying of the tape is achieved with cooling medium.
- a plurality of spray nozzles 10 are arranged one behind the other, so that along the longitudinal extent of the openings, a continuous flow of cooling medium is ensured.
- the lower spray bar 5 (analogous to the upper spray bar 13) has a plurality of spray nozzles 10 which spray the tape 2 with cooling medium.
