ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of stirring non-solidified IM1ii1i of a cast strand. Such a straw land is formed in a mold into which a tap flow 1 or straw jet is introduced either via a casting pipe or directly. A static magnetic field is applied to the mold to affect the passage of tap flow through the melt in the mold. This static magnetic field utilizes the inflow movement of metal into the tap stream to brake or slow down the velocity of the tap stream in the melt and divert the tap stream. Such a method is known from Japanese Patent Application No. 723.77/811.

It takes about 7 seconds for 1 meter. The motion of the steel is thereby braked and the tap flow is diverted.
((So-called eddy current brake occurs) 1.
The depth of the strand is reduced and most of the slag can be moved towards the F surface without being deposited inside the strand skin.

。The method according to the present invention is characterized by
# Place it near the pipe or mold.
Molten parts are present on the sides of the casting jets 1 to 1 so that they are not directly affected by the casting jets, and when the jets are decelerated, these melted parts are generated by the magnetic field and these melted parts. Stirring is done by using a flowing electric current. According to this method, the surface quality of the cast product (slab, billet or bloom) can be significantly improved. The present invention will be described in detail below with reference to the accompanying drawings.

πは磁界の鎗の導関数である。From this casting pipe, a stream of casting material, ie a jet 2, is injected into the &% building mold 3 melt for continuous &I building. The static magnetic field 13 from the large number of magnetic poles 4 is applied to the mold 3
or across the casting pipe 1 to generate an electromotive force F in the melt acted upon by the flow of casting material. (
In a moving melt, the electric charge dφ π is the spear derivative of the magnetic field.

This force generates the stirring horns of Takeda Zuru. Therefore,
A braking action l-1 is obtained in the melting part of the flow of casting material, and a stirring force F2 is obtained adjacent to the flow of casting material.

の欅拌り法。[Claims] A tap flow or jet is introduced into the mold in which the strands are formed, either through a casting pipe or directly into the mold, and a magnetic field is applied to the mold so that the strands are formed in the melt. In addition to applying the static magnetic field to the path of the tap flow and utilizing the movement of the S group flow in the tap flow, the tap flow is divided by slowing down the speed of the tap flow in the melt. In the mold, the magnetic pole (4) that generates the static magnetic field is placed h1 close to the one-piece pipe (1) or the mold (3), and is placed on the side of the incoming tap flow (2). Therefore, the molten part (6), which is not directly affected by the tap flow, interacts with the magnetic field (B) from the magnetic pole and the current (1) previously induced during the deceleration period of the tap flow. Keyaki stirring method of the non-solidified area of a cast strand, characterized in that it is stirred by (F=RXi).
