  • the invention relates to a device for cooling the work rolls of a roll stand, comprising one for each roll Spray nozzles equipped cooling water channel on a spray bar as well Means for supplying cooling water or for removing heated water, as well as one in the point of assignment to the upper work roll Angle to the rolling stock surface arranged cooling water guide plate with a front wiper associated with the roller, and tight an approximately horizontal cooling water guide plate below the rolling stock level with a scraper assigned to the lower roller.
  • the invention further relates to a related method for Cooling of the work rolls.
  • the main amount of heat is in contact with the work rolls the rolling stock in the roll gap, increased by that in the plastic Shape change of the rolling stock additionally developed rolling heat, still due to the frictional heat generated between the rolling stock and the rolls and the introduction of frictional heat in the contact area between Work roll and backup roll as well as additional heating by Radiant heat in the inlet and outlet area.
  • DE 36 16 070 A1 discloses a roll cooling device for a Roll stand comprising cooling water baffle plates, each a curved one Have area along the circumferential direction of a roller and located near the respective roller, further a cooling water supply manifold for supplying cooling water to a cooling water channel, which is limited by the cooling water guide plate and the roller, one Water drainage manifold to drain the from the cooling water supply manifold supplied cooling water from the cooling water channel, a supporting element for holding the cooling water guide plate and curvature adjustment elements, which corresponds to the curvature of the side plate Change the diameter of the roller.
  • the thickness of the guide plate increases from the edge sections to the center of the guide plate in the circumferential direction of Roller closed.
  • This device results in a forced cooling water flow, the shape of which is the outer circumference Corresponds to the roller, being at a constant distance from the roller a space between the cooling water guide and the roller results, is conveyed by the cooling water under pressure, whereby an average heat transfer coefficient with about four times the value of conventional heat transfer coefficient is to be achieved.
  • the known device requires a very large technical Effort, in addition, the curvature adjustment organs are difficult are arranged accessible and the periodic readjustment continues the curvature requires a high level of maintenance. Because besides the coolant in a narrow gap along part of the Roll surface is forcibly guided, this takes when flowing through heat in the gap and loses to the same extent Cooling intensity.
  • Laid-open specification discloses a device for the outlet side Cooling of work rolls with one upper and one lower, Wiper cooling water guide plate, which on the work rolls facing end with spray nozzles for a cooling water-air mixture is equipped.
  • Laid-open patent discloses on the front of cooling water baffles arranged water mist nozzles, as well as additional upper and lower spray nozzles for cooling water. With this device to prevent cracking on the surface of the work rolls become.
  • Laid-open specification discloses an outlet-side cooling device for work rolls with triple one above the other or one below the other arranged cooling water channels equipped with spray nozzles as well as an upper and lower cooling water guide plate with end Scraper.
  • the top baffle is spaced from the top Roll a channel parallel to the roll with openings for discharge Cooling water assigned to the one open at both ends Cooling water drainage channel forms. This is supposed to warm a drain Cooling water from the middle area of the work roll evenly can be reached on both sides. Because, however, heated cooling water in this device only with a natural slope and through relatively narrow channel cross-section from the center to both sides drains, the liquid throughput is comparatively low and also cannot be increased arbitrarily.
  • the present invention is based on the aforementioned prior art the task of an apparatus and a method for Cooling the work rolls of a roll stand in the preamble of Claim 1 to further develop the type mentioned and to improve that the above difficulties and technical Limits are overcome, in particular the influence of outlet-side cooling to the thermal behavior of the work rolls optimized and the heat of the roller surface as early as possible can be deprived of the penetration of heat into the depth of the Reduce work rolls as much as possible and beyond by zoning forcing the removal of cooling water on the zonal formation of the thermal crown along the Take axis of the rollers.
  • the device according to the invention is through training a liquid-carrying gap and its connection to a powerful cooling water extraction for the upper work roll as well by arranging suction pipes in the between the lower Cooling water baffle and a surface area of the lower roller resulting fluid-carrying corner area and its connection a powerful cooling water extraction system Optimization of the discharge conditions of the "used" cooling water created by a pressure drop artificially increased by means of negative pressure. This results in the possibility of cooling water discharge, For example, by connecting the laxative organs according to the invention to the suction side of powerful pumps within Control borders.
  • the measure taken with the device according to the invention be that the liquid-carrying gap through longitudinal walls in at least three - side - middle - side - parallel channel areas is subdivided and each of these channel areas has a predetermined one axial extension and individual cooling water suction assigned. This can influence within predetermined limits on the cooling effect of the work rolls - seen in the axial direction - Be exercised to keep the thermal crown in the desired Way to influence.
  • a method for cooling the work rolls of an outlet Roll stand of the type characterized in claim 1 is thereby characterized that on the one hand in the inlet area in front of the suction piece of the gap and on the other hand in the corner area between the lower Work roll and the assigned cooling water guide plate after heat exchange water generated by the rollers by applying Vacuum through an upper and a lower cooling water suction is subtracted.
  • the method according to the invention provides that the cooling water suction via the axial extension of the work rolls divided into a number of suction areas and this different suction powers can be assigned.
  • the device shown in Fig. 1 for cooling the outlet side Work rolls 1, 2 of a roll stand 15, not shown in detail comprises a cooling water channel equipped with spray nozzles 3, 4 for each roller 7, 8 on a height-adjustable spray bar.
  • the device has means 5, 6 for supplying cooling water. medium for the orderly discharge of heated water are in this construction not provided.
  • the rolling line is with x-x and in one dash-dotted line indicated.
  • Assigned to the upper work roll 1 is a cooling water guide plate at an acute angle to the surface of the rolling stock 9 with a front, abutting the roller 1 Scraper 11 arranged. Is just below the rolling stock level x-x also an approximately horizontal cooling water guide plate 10 with a wiper 12 resting on the lower roller 2 is provided.
  • the upper cooling water guide plate 9 is on the work roll 1 opposite end in a universal joint 17 and is supported by a power means, for example a pneumatic cylinder 13 with the Scraper 11 under predetermined force approximately tangential to the upper work roll 1 created.
  • the lower cooling water guide plate 10 is at the end facing away from the work roll 2 in a joint 18 stored and is with the scraper 12, for example, under the action their own weight in the stripping position.
  • Figure 2 shows the design of the device on the outlet side Cooling of the work rolls 1, 2 of a roll stand according to the invention.
