    The invention relates to a device for applying a hot zinc coating to a steel strip or sheet. The purpose of the invention is to improve the quality of the coating. To achieve this, the steel brush 9 is washed by a strong gas flow, which performs the functions of cooling the brush and hardening the liquid zinc droplets that fly off during the brushing process. For this, the casing in which the brush is placed is divided by a partition into a forced cooling zone and a zinc core collection zone having several dampers and a hopper for collecting zinc particles. Each zone is connected to an individual suction system. All these measures eliminate the coating from non-melting zinc, increasing the quality of the coating and eliminating a number of adjustment operations. 1 hp f-ly, 4 ill. SU)

    The invention relates to the manufacture of a sheet or strip of galvanized steel, in particular for stamping.
    The purpose of the invention is to improve the quality of the coating.
    FIG. 1 shows the installation, partial view; Fig, 2 - the same, side view, section; FIG. 3 is a section A-A in FIG. 2; FIG. 4 is a section BB in FIG. 2,
    FIG. Figure 1 shows a classic galvanizing plant containing a bath of molten zinc through which steel strip 2 passes, exits from a furnace (not shown) and transports in channel 3 with a protective atmosphere. This tape passes through the roller 4 installed at the bottom of the bath, comes out vertically from the zinc bath and is dried using a pneumatic device 5 installed adjacent to the surface of the bath with zinc. The belt continues its way vertically,
    as indicated by arrow 6.
    The device also includes a movable support 7 capable of longitudinally moving in a horizontal plane parallel to the plane of the belt on the rails 8.
    The brush 9 is mounted on this caliper and is rotated in the direction indicated by the arrow 10 using means (not shown) from the bottom plate 11 mounted on the caliper 7, the axis of this floor brush 9 and the cooling substance passes through it. property
    The counter-roller 12, installed on the side of the tape opposite to the side being brushed, serves as a support for the tape, which it is pressed in the direction of the brush so that the plane of the tape is slightly cut to the surface of the working part of the brush 9. The brush 9 is placed in the case 13 which is connected on one side with a system 14 of forced circulation of cooling air; leaving the bunker 15. The system is operated by a blower 16. On the other hand, the casing 13 is connected to the dust suction system 17, which goes to the bunker 18 and actuates another air-blower 19.
    Both systems 14 and 17 are designed to minimize the amount of dust and circulators i.

    FIG. 2, a casing enclosing the brush 9 includes an inlet portion 20 of a forcedly suction flow of cooling gas. In addition, the casing is divided into two zones with the help of a partition 21, the upper edge of which is located near the bottom forming the brush 9.
    In the first zone 22 there is a flow of gas that cools the brush. This forced circulation zone covers a large part of the outer surface of the cylindrical brush so that; to ensure its most efficient cooling, and is located opposite the belt 2 relative to the brush 9. This zone of forced circulation of the cooling gas is connected to the chamber 23 connected to the cooling gas suction system.
    The second zone 24, which is almost hermetically separated from zone 22 by a partition 21, at least in relation to zinc particles that form 1x during brushing, is opposite the side of the liquid zinc-coated tape, which has been brushed 9,
    In this zone 24, reflectors 25-27 are installed in the form of inclined planes, which direct the discarded particles of solidified zinc to the base of the casing 13, where they are sucked in by a channel 28 connected to the system of suction of zinc dust. Preferably, the reflectors can rotate around horizontal axes and exit through the slots 29 of the casing 13 o.
    Reflectors 30 are located at equal distances x5 that surround the anvil roller 12 on a significant part of its periphery and are installed vertically, as shown in Fig. 3, so as to vertically direct the gas flow existing on the side of the belt opposite to the side to be brushed. These vertical reflectors 30 form vertical partitions that prevent possible redeposition of the zinc dust formed during brushing of the opposite side of the sheet. The drawing can adversely affect the quality of the side with the classic zinc coating.
    The vertical reflectors are 30 times71; in the middle zone, they are partitioned in the form of 1 1 in the form of an inclined flat (directed toward the tape of 2 n perpendicular reflectors. This inclined plane with its lower edge goes into the chute 32 and forms a relatively small slope 33 with KOTOPMIM widths associated with the gas circulation system 14 cooling the brush (Figure 2n3),
    The reflectors 34, mounted under the partition 31, are arranged in two groups adjacent to the edges of the sheet and separated by a central zone 35.
    Since the casing 13 and the reflectors 30 and 34 are of equal width and extend far beyond the edge of the belt 2, as shown in FIGS. 3 and 4, the gas flow going around the belt 2 to the side opposite the reference
    porting tape, in the form of a holder and a support roller, mounted on the Sugiurt bath, carrying a hook with a cylindrical cooled brush mounted on it rotatably, while the casing is connected to a forced air suction system, characterized in that, in order to improve the quality of the coating , the casing is divided by a partition into the forced 1. chamber; cooling liquid circulation and the zinc dust collection chamber, while the partition is displaced from the axis of rotation of the brush towards the tape being processed, and its upper edge ka is at the level of the lower forming brush, and the collection chamber
    Controller 12 is separated and guided by 20 mounted obliquely, as shown by the arrow a
    Kami and a hopper for collecting particles of solidified zinc, and each chamber is associated with an individual suction system; in addition, the device is equipped with vertical reflectors mounted on the unworked side of the tape and separated in the central part by a wall made in the form of an inclined plane and connected to the forced suction system air through the gutter
    In order to effectively prevent the re-deposition of zinc particles formed during brushing, beyond the edges of the side of a sheet with a classic zinc coating.
