    An apparatus for producing a continuous curtain of cooling liquid to cool a hot metal workpiece issuing from a rolling mill. A header tank with an elongated slot formed lengthwise along its underside is provided. An elongated nozzle, located in the header has an outlet extending from the slot. Both the inlet and outlet of the nozzle are generally rectangular in form but differ considerably in cross-section. An insert divides the nozzle into several passageways.

    one
     The invention relates to ferrous metallurgy and can be used in the cooling of a hot metal cavity leaving the pro-rolling mill.
    A device for supplying a coolant to the rental surface is known, which includes a water-pressure tank with a slit nozzle made in. View of a rectangular insert mounted in the slot of the bottom of the tank so that its inlet is located inside the tank above the level of its bottom 1.
    A disadvantage of the known device is the insufficient efficiency of cooling of the rolling stock due to the instability of the supplied fluid flow, especially at a considerable height of the tank installation.
    The purpose of the invention is to increase the cooling efficiency by stably supplying the chiller with a continuous coherent flow to the rolling surface.
    This is achieved by the fact that the insert has a large cross-sectional area on the side of the inlet, one on the side of the outlet, and inside the insert there are spacers that divide its internal cavity in the area between the inlet and outlet on a number of longitudinal adjacent 5 channels. The entrance of the insert is formed by side walls converging at an angle to the part of the insert containing said separating means, and the output part of the insert
    10 is formed by side walls converging at an angle from the part containing said separating means. The output part has an end section formed by parallel
    DB side walls, joined with the mentioned walls, converging at an angle. The separating means are made in the form of a series of pipes placed in the inner cavity of the insert 2E; separators are made of plastic. At least one extreme channel at the end walls of the insert are inclined in the outer sides to the outlet opening; a series of channels in the end walls of the insert are inclined in {the outer sides in the outlet, the angle of inclination I in relation to the channels in the middle
    39 insert parts installed without
    the inclination increases in fan-like direction from the channel to the channel in the direction of the end walls. The end walls of the insert are installed with HaiOtoftoM in the outer sides at an angle corresponding to the angle of the nayyun extreme to the walls of the kangshov.
    FIG. 1 shows the proposed structure, top view of FIG. 2 the same cut; in fig. 3 is the same longitudinal section (embodiment); in fig. 4 - the same, in a perspective view; in fig. 5 shows devices for obtaining continuous coolant on opposite sides of the metal strip.
    The metal strip, moving along the mill table (not shown) Passes under the pressure tank 2, in the lower part of which there is an oblong slot 3. It is much more linear than the width of the tank, and is located essentially perpendicular to the direction of movement of the strip 1. Cooling water It is directed to the pressure tank 2 through the inlet pipes 4 associated with the internal volume of the pressure tank.
    Inside the tank there is an insert with inlet 5 and outlet 6, some of which have an elongated, usually rectangular, shape, but the cross-sectional area of the inlet is much larger than the outlet. Between the inlet and the outlet there is a part 7 with parallelly disposed sides, which at its upper end is connected to the inlet 5 by a converging part 8, and the lower end of part 7 is connected to an additional part (opening) 9 with parallel walls 10. The internal volume of the part of the insert, which is located between the part with parallel walls 7, is divided into many separate, but smyyy channels 11, the most direct direction between the input and the output. The channels are formed by a metallic or plastic material. This provides a plurality of individual chambers that can have a rectangular or other suitable cross section.
    FIG. Figure 3 shows the cooling of the moving elongated part, for example, a metal strip or plate 1, on a roller table represented by roller 13. A pressurized tank with a central rectangular opening 9 in the bottom of the tank is installed above the roller floor and across it and 1 inside the pressurized tank , passing down through the hole 9. The insert includes a pair of side plates 15, the ends of which are attached to the end Sh1astin: am 16,; BOKOBiae 15 and 16 end plates, at their upper ends end up below the top of the pressure tank, and
    their lower ends are tightly fitted to the hole 9, the side plates 15 are given such a profile that the insert has the first converging part formed between the inclined parts 17, the vertical part formed between the parallel sides 18, the second converging part formed between the inclined parts 19, and finally, a short end portion passing through the opening 9 and formed by parallel vertical portions 20. Inside the vertical portion of the insert and between the vertical portions 18 there is a part 21 in the direction of These inserts are divided into many separate but adjacent channels 22, which, except for the insertion ends, are parallel and vertical. At the insertion ends, the guide channels are inclined with riocTORHHM increasing corners (channels 23). As the channel walls at the edges of the part 21 are inclined towards the vertical, then the space between and the end plates 16 is filled with solid faces (Box 24) extending to the exit of the nozzle. The channels 22 have a largely square cross-section, and the guide part can be made from extruded metal or cast, or extruded from COOT corresponding to plastics.
    In operation, water under low pressure (0.28 kg / cm) is supplied to the outlet pipes 4 and flows at low speed over the closures formed by the sharp upper edges of the upper inclined parts 17 of the side plates 15 of the insert. Water flows smoothly along the inner walls of these parts to part 21 and, due to the gates, water flows evenly along the length of the insert, i.e. in size, parallel to the opening 9. Then the water fills all the channels 22 and flows through them, and the channels 22 are of such dimensions that the flow of water through each of. they approach the vertical and all the turbulence of the incoming water is eliminated. Water leaves the canals and individual flows of the discharge into one continuous stream that goes through the neck formed by parts 20 for supplying water in the form of a continuous curtain to the workpiece 1. Incomplete channels 23 give the IODINE speed at the ends of the insert a horizontal component - so that the curtain The one leaving it diverges, as shown by lines 25, representing the edges of the veil. The performance of the tensioning tension leads to a contraction inside the edges of the curtain, as a result of which the divergence gradually decreases as
    water drops and in fact the divergence turns into convergence. The channels 23 that are different from the vertical coal are chosen so that the curtain winding, when it hits the workpiece, is approximately equal to the width of the neck of the insert, i.e. the distance between the end plates 16. Consequently, the workpiece is cooled uniformly over the entire cross section.
    The device shown in FIG. 1-4, are positioned above the roller table, however, if necessary, it may be located below the supply table, a cooler on the lower side of the workpiece.
    FIG. Figure 5 shows a conventional unit for cooling a hot metal lath 1 leaving the rolling mill. The machined frame rests on the roller table 13 and the curtains 26 and 21 of the coolant are directed respectively to the upper and lower sides of the workpiece. The top curtain is formed by an insert 28, usually located so as to cool the workpiece above one of the rolls of the roller table 13. Located subplanar, the insert 24 may be inclined so that the curtain 27 falls on the lower side of the strip at an angle to the vertical. Thus, when there is no strip over the veil, as in the case of the start and end of rolling, the water does not fall back onto the veil. ,
