Definitions

• the invention relates to an intermediate container for pouring molten metal into a strip casting machine, with a container that holds the melt and a spout arranged on the bottom of the container with a pouring tube through which the melt is passed between pouring tubes of the strip casting machine.
• a distribution vessel is arranged above the casting channels and a pan is arranged above it.
• a pouring tube on the spout of the pan protrudes into the distribution vessel, which in turn has a spout and a nozzle leading between the pouring tubes.
• a plug closure is provided in the pan for a controlled pouring of the melt.
• the present invention was based on the object of designing an intermediate container in such a way that the melt flows in between the pouring tubes with the smallest possible kinetic energy with a laminar, uniform flow and the bath level that forms between these pouring tubes remains as flat as possible.
• the object is achieved according to the invention in that the interior of the container is divided into at least two chambers which are connected to one another by a through opening, of which the melt can be filled into one chamber, while the other chamber is provided with the spout, with a control valve in the Through opening, the amount of melt flowing from the first chamber into the second chamber is controllable and in particular the bath height in the chamber with the spout is lower than that in the other chamber during the pouring.
• the bath height in the chamber with the spout is between 10 and 50% with that in the other chamber.
• a constant bath height of the melt is set in the chamber with the spout during the casting, which bath bath can be adjusted by the control valve and a measuring device.
• the inlet of the nozzle forming the passage opening is arranged offset upwards from the bottom of the chamber into which the melt enters, whereby this chamber can serve as a cutting chamber for impurities in the melt.
• Another embodiment of the intermediate container according to the invention provides that a partition is provided in the interior of the container, which is eccentric is arranged so that the chamber to the chamber with the spout is larger, preferably two to three times as large.
• Fig. 1 an inventive intermediate container with a
• FIG. 1 shows an intermediate container 10 lined with refractory material 15 for pouring molten metal into a strip casting machine 30 known per se, by means of which thin steel strips with a thickness of a few millimeters and a width of up to 2 meters are produced.
• the casting pipes 31 and a housing box 32 enclosing them are indicated by the strip casting machine 30, which is only partially illustrated.
• the intermediate container 10 has a lid 15 ', an interior receiving the melt 13 and a spout 14 arranged on its bottom.
• the melt 13 is filled through an immersion tube 16 which extends into the container 10 and is connected to the spout of a pan (not shown in more detail) ,
• a pouring tube 25 forming the spout 14 with a pouring tube part 25 ′′ and with openings 27 projects into the molten bath 33 between the rotating pouring tubes 31.
• the interior of the container 10 is advantageously filled with inert gas. Between the container 10 and the housing cover 32 there is also a bellows 36 surrounding the pouring tube 25 is provided.
• the interior of the container is divided into at least two chambers 11, 12 which are connected to one another by a through opening 17, of which the melt 13 can be filled into one chamber 11, while the other chamber 12 is provided with the spout 14, the one from the first in the second chamber 11, 12 flowing amount of melt can be adjusted by means of a control valve 19 at the passage opening 17.
• a vertical partition 18 is expediently provided in the interior of the container, which is advantageously arranged off-center, so that the filling chamber 11 is approximately two to three times larger in volume than the chamber 12 with the spout.
• the control valve 19 designed as a plug closure is expediently actuated in such a way that a constant bath height of the melt is maintained in the chamber 12 with the spout 14 during casting, which bath bath can advantageously be adjusted by a control element and a measuring device.
• a rotary closure, a slide closure or the like could also be provided for the control valve.
• the inlet 17 'of the nozzle 26 forming the through opening 17 is arranged offset upwards with respect to the container bottom of the filling chamber 11. This offers the advantage that any inclusions from the pan into this chamber settle on the floor and do not reach the subsequent chamber 12.
