な、ど）の実施に当って生じる。(Prior Art) Slag is often present on the surface of molten metal during melting and refining, but this slag only needs to be present in an amount suitable for the purpose of oxidation prevention and refining. On the other hand, as the amount of molten metal increases due to progress of melting, the amount of slag usually increases, and slabs exceeding the appropriate amount need to be removed for effective use of the container. The need for such slab removal was solved by the inventors'"reactor iron manufacturing method" (

。Of course, slag can be removed by temporarily tilting the container, but it is preferable to perform the melting and refining operations without interrupting the tilting, and also to minimize heat loss. , avoid opening the container. In particular, in the multi-layer device that the inventors established and separately proposed for the above-mentioned "reactor steelmaking," it is advantageous to have a structure in which the furnace body slides laterally, so that the slag can be removed without continuing to melt the scrap. Removal is required.

This is a method for removing a part of slag 11 which increases as the slag 11 increases, and a sensor 4 for detecting the molten metal level is provided in a molten metal container 1 having a slag tap hole 22 on the side wall that can be opened and closed by inserting and removing a plug 21. When the hot water level rises to a predetermined level below the slag tap hole 22, the plug 21 is pulled out as shown by the dotted line in the figure to open the slag tap hole 22, and the slag 11 is passed through the spout 3. When a predetermined amount of slag has flowed out, plug 2
Insert 1 again as shown by the solid line and insert it into the slug tap hole 2.

定することにより、溶湯十に所望の厚さのスラグ層を残
すことができる。(Function) Due to the failure of the slag tap hole, the slag that was above the lower surface level flows out, leaving only the slag between it and the hot water surface. Therefore, by appropriately determining the height of the molten metal surface at which the plug is pulled out, it is possible to leave a slag layer of a desired thickness on the molten metal.

、自動化が実現する。By detecting that slag has stopped flowing, for example by monitoring the flow on the spout, the plug can be moved to automatically close the slag tap hole.
Automation is realized in conjunction with unplugging based on the detection of the hot water level.

、といったスラグ除去も可能である。If the emphasis is on discharging a predetermined amount of slag rather than leaving a predetermined amount of slag, then the spilled slag is received in a slag pan, and a plug is inserted when the increase in weight Φ reaches a predetermined value. It is also possible to remove slag by closing the slag tap hole.

溶解を続行することを特徴とする方法。(1) A method for removing part of the slag on the surface of molten metal that increases as the amount of molten metal increases as melting progresses, and includes a slag tap hole on the side wall that can be opened and closed by inserting and removing a plug. A sensor is installed in the molten metal container to detect the molten metal level, and when the molten metal level rises to a predetermined level below the slag tap hole, the slag tap hole is opened and slag flows out, allowing a predetermined amount of slag to flow out. If so, the method is characterized in that the slag tap hole is closed and melting continues.
