FIG.3
INVENTOR HANS-JOACHIM KUTZER ATTORNEYS CONTAINER WITH SLIDING SHUTTER FOR A LIQUID MELT The invention refers to a container with a sliding shutter for a liquid melt comprising an orifice plate with a flow passage firmly set on the bottom of the container, opposite to it a slidable valve plate with a How passage, and a refractory body permeable to gas, through which an inert gas can be fed to the melt set in the flow passage of the orifice plate.
In this kind of container the object of feeding gas to the melt in the area of the flow passage of the orifice plate is to prevent the metal from hardening due to cooling and thus occluding the flow passage. Furthermore this measure helps to homogenize all of the remaining melt in the container.
There are also other reasons for feeding gas to a melt, particularly reaction gases. For instance with aluminum melts, chlorine is introduced in order to free the melt of undesired metalloids, particularly sodium. The reaction gases were in the past blown into the melt from above through graphite pipes.
An object of the present invention is to provide a more effective way of degassing the melt, without having to use graphite pipes which are highly exposed to wear and tear.
A further object is to provide a container, which has a gas permeable body on the outlet thereof, with a valve connection, for instance a three-way valve, to a gas feed pipe which is connected with the gas permeable body for introducing selectively various gases. In this manner reaction gases can be fed through the gas permeable body into the melt.
A still further object is to make it possible to use only one means for cleaning, homogenizing, degassing and securing an undisturbed drain of the molten metal. The gassing of the melt from below permits a high gas utilization and the utilization of a gas permeable body, such as a gas sink, which produces small gas bubbles and allows an intensive action of the gas upon the melt.
With the above and other objects in view which will become apparent from the detailed description below, some preferred embodiments of the invention are shown in the drawings, in which:
FIG. 1 is a vertical section through a sliding shutter set on the bottom of a pouring ladle, whereby a gas sink is inserted into its orifice plate,
FIG. 2 is a cross section along section line IIII in FIG. 1,
FIG. 3 is a vertical section through a modification of the invention.
The drawing of the lower part of a pouring ladle with a sliding shutter in FIG. 1 a pouring ladle having a metal casing 1, an internal refractory lining 2, a refractory block 3 with an inlet hole 3' and a refractory pouring insert 4 embedded within the hole by refractory mortar. The casing plate 5 of the sliding shutter which is screwed tight onto the casing 1, consists of a fixed orifice plate 6 and a sliding part set across said orifice plate in guideways 5" whereby a cast iron lid 5 is screwed onto the housing plate 5. The sliding part is composed of a cast iron supporting body 7 with a nozzle 7 a valve plate 8 positioned therein, and an outflow jacket 9. The displacement between a closed position, whereby the sliding plate 8 seals a central flow passage of orifice plate 6, and an open position whereby the flow passages in the orifice plate 6 and the valve plate 8 align, is achieved by means of a hydraulic drive 10.
In order to avoid the freezing of the melt over the valve plate 8 when it is in a closed position and so as to make it possible at the same time to feed a finely dispersed reaction gas, for instance chlorine, into the melt, according to the device of FIG. 1 a porous, gas permeable gas sink 11, such as a ring-shaped insert, is set into the orifice plate 6. Sink 11, as shown in FIG. 2, is connected with a gas feeding conduit 12 through orifice plate 6. Through this conduit 12 and the gas link 11, different gases may be fed into the melt according to need, through a three-way valve 13. An inert gas can be fed, for instance nitrogen or argon, and a reaction gas, for example chlorine.
The modification according to FIG. 3 is different from FIGS. 1 and 2, in that the pouring insert 4 forms the gas sink. The gas is fed in this case through conduits l4 and 15 through the valve plate 8 and the orifice plate 6.
As a deviation of the shown applications the expert may use many different forms of construction for the gas permeable body as well as many different ways for connecting gas conduits with the latter. Since the function remains always the same, the invention covers also these various modifications.
