もに作業がしにくい欠点がある。Such means for removing slag has the disadvantage that the melting furnace usually has an inner diameter of about 6 m, and the slag shovel also requires about 4 to 5 m, and it is difficult to work.
しかも溶湯の温度がアルミ溶湯において７００〜８００
℃にも及び高温に対する危険度が高かった。Moreover, the temperature of the molten metal is 700 to 800 for aluminum molten metal.
The risk of exposure to high temperatures was high.

りわけ溶解炉１の底部に有する浴湯Ｒに推力を与える。2, an inductor is used to generate a moving magnetic field in the direction of the arrow Y1, and its arrangement is located approximately at the center in the direction perpendicular to the direction of the moving magnetic field of the melting furnace 1, and the direction is on the opposite side to the direction of the moving magnetic field. Position the outlet 1a. In addition, the inductor 2 is moved to the periphery of the bottom of the melting furnace 1 at times other than the melting operation to strengthen the stirring action in order to equalize the temperature and uniformly distribute the additives. Page 5 JP-A No. 61-107092 (2) In the above configuration, when the molten metal R is accumulated to the bottom of one station for slag removal, the slag rises to the surface of the molten metal 1, and its distribution The state becomes uniform. In this state, when power is supplied to the inductor 2 to generate a moving magnetic field in the direction of the arrow Y1, this moving magnetic field acts on the molten metal R, which is formed especially at the bottom of the melting furnace 1. Gives thrust to bath R.

しない領域が生ずる。Therefore, the molten metal RU fully starts moving in the direction of the arrow Y2. The molten metal R moves from the center bottom toward the side wall opposite to the slag outlet 1a. Next, when it reaches the side opposite to the slag outlet 1a, the molten metal R is pushed upward, and this raised molten metal R causes the flow of the molten metal R toward the slag outlet 1a due to gravity. The slag R' that is generated and floats on the surface of the molten metal R along the flow of the molten metal R moves toward the outlet 1a. In this way, slag R/t, s-slag is collected on the side of slag outlet la,
As a result, a region where no slag R' does not exist gradually appears from the side opposite to the slag outlet.

し作業は大型化の影響を受けることがない。As described above, in the method for removing slag from a melting furnace according to the present invention, an inductor is placed facing the bottom of the melting soap 1 in a direction perpendicular to the direction of the moving magnetic field of the inductor, and the melting furnace i
A moving magnetic field is applied to the molten metal filled with carbon, a slag outlet is provided on the side surface in the opposite direction to the direction of the moving magnetic field, and slag is removed from the slag outlet. Based on this method, a very short slag rod is required for removing the slag, and even if the melting furnace becomes larger, the slag removal operation will not be affected by the enlargement.
従って、高温の溶湯上に浮上するノロ取り作業の安全性

き棒にてノロ取出し作業７行うこともできる。Note that the method of the present invention is most effective when the melting furnace is circular in plan, but it goes without saying that even a rectangular melting furnace can be put to practical use.
In addition, the slag removal operation 7 can be performed from above using a slag scraper without necessarily providing a slag removal port.
