"Hot Bombing Drum"

The invention is left with a rotating band casting sti'oiumel, which is partially immersed in a molten metal bath and to be continuously withdrawn from metal tape serves, which consists of molten metal that solidifies on the circumference of the drum.

The general principle of pulling a continuous metal strip from a molten metal bath by solidification the melting on a partially cooled drum immersed in the melt bath is described in the German patent specification 7ii 133. In this known method, however, there are three other methods, as is the case with other types Process for continuous casting vöii ~ i?

ORIGINAL INSPECTSO

Zofren confuses itself, which begins to merge, with it the company can run at a x * speed necessary to achieve a desired from the ideal point of view To achieve production rate.

The object of the invention is therefore to create a device with which a cooling water circuit in the interior of the drum, which is partially immersed in the molten metal, can be used to find the ν, ίίχ-κιο-pickups with the help of the water to increase the walls dex · drum significantly and the total amount deram ^r ef ührten ■ iii'ine steeds to ver ^

According to the invention, this is achieved with only one cooling device, which is characterized by the following elements: An inlet tube which is axial to the J "ro: i; :: i?

A tapered nozzle j6 extends inwardly from the shaft 28 and has longitudinal slots 37 spaced around the circumference of the nozzle. A ring 40 with a U-shaped cross section. is carried in part on the disc 33 by means of screw bolts 41 and forms the circumference of the drum.

A tubular exit shaft or tube 42 forms the outer part and is firmly attached coaxially to the shaft 28 in a support 29. The outer end of this shaft points a connected pipe through which the cooling water is discharged. The inner end of the shaft 42 has an extension sleeve 42a which is fixed on it and on the with A hub 44 is guided using a bearing sleeve 45. A disk 46, which is approximately the same as the disk 33, is on the inner end of the hub 44 fixedly attached. The disk 46 carries a heat-resistant ring with the help of screws 35

34 and the ring 40 with the aid of screws 41, whereby.die Support similar to that of Seheibe 33 1st. The inner end , the sleeve 42a extends across the width of the ring 40 and ^ has longitudinal slots 47, which are spaced around the circumference fep-JKilse are arranged.

The ring 40 is the drumstick !!, on the surface of which look the liquid metal solidifies as soon as the pouring pad 13 has been raised sufficiently to bring the surface of the molten metal in the ladle above the bottom point on the drum. So that large amounts of heat are quickly absorbed by the Tromiue! Radial guides 48 and adjacent radial plates 49 and 50 are provided, which together have inlet channels 51

form which with the. Connect slots 37, and outlet channels 52 connected to the slots 47 are. As a result, with this construction, the water released under pressure to the nozzles 36 flows outward through the channels 51. The outer ones Ends of plates 49 and "50 midway between the radial guides 48 are connected by curved plates 53.

The radial guides 48 and plates 49, 50 and 53 extend between separate side plates or disks $ h and 55, creating a construction similar to the stationary stator of a pump. The plate 54 is mounted on a ring 56 which is carried by the extension sleeve 42a of the stationary shaft 42. The plate 55 is carried by a ring 57 attached to the end of the sleeve 42a and seated in a recess in the structure in the inner end of the shaft 28. ..'..._

The radial guides 48 consist of wedge-shaped, inner base or peg part ph 48a and outer, diverging head parts 48b, which are formed by SehrajLibeif 58 are attached to one another. Each headboard. 48b "has a curved surface 59, the entering Water around the circumference along the interior of the drum 40 leads, as well as a similar surface 60, which a Part of the water circulating around the drum diverts to the outlet channel 52. Since the drum 40 during of the casting rotates relative to the guides 48 are all interior parts of the drum constantly under the cooling effect exposed to a stream of water flowing at high speed, part of which is constantly being withdrawn and passed through incoming cooling water is replaced.

■ In. Radial Iliohtimg in the round head parts high in the guides ^; Pins i > L arranged in 18 cause turbulence in the water layer, which flows around the circumference atif the tromnieliimenseit, whereby the cooling effect is increased.

From this it follows that means are created according to fulfillment with 'which an extraordinarily effective cooling effect produced by a rotating casting drum, whereby, the permissible retrieval speed and the tonnage capacity the device increase.

In the preferred embodiment described here many changes are conceivable without the protection— scope of the invention is left.
