ている。(Example) Next, a continuous casting apparatus using the belt of the present invention will be explained with reference to an example shown in FIGS. 1 to 6.
Figures 1 to 4 show belts used in a vertical twin belt caster continuous casting machine and a rotary caster continuous casting machine, and Figure 5 shows belts used in a vertical twin belt caster continuous casting machine. Fig. 6 shows the casting area of a rotary caster type continuous casting apparatus. 1 to 6, 1 is a belt, 2 is a short side mold, 2a is a flange, 3a is a drum, 4 is a solidified layer, 4a is a molten metal, 1
0 is a moving side permanent magnet, 10a is a support rod, 10b is a presser foot, 10c is a nut, 11 is a fixed side permanent magnet, 11b is a support arm, 11a is the tip of the support arm 11, 12 is a repulsive force, and 12a is a With tension in the width direction,
A large number of support rods 10a are protruded in the width direction from both side edges of the belt 1 having a constant width, and two attachment holes provided in the moving side permanent magnet 10 are engaged with the support rods 10a, and the magnetic poles of the permanent magnet 10 are fixed. After making sure that the surface is substantially parallel to a plane including the side edges of the belt, it is attached via a presser foot 10b and a nut 10c. Further, the tip portion 11a of the support arm 11b protruding from the stationary frame (not shown) is shaped to surround the moving side permanent magnet 10 attached to both side edges of the belt 1. Further, the fixed permanent magnet 11 is attached to the tip portion 11a of the support arm 11b so that the outward magnetic pole surface of the fixed permanent magnet 11 is close to and opposed to the inward magnetic pole surface of the moving permanent magnet 10. These permanent magnets 1
The polarities of the opposing surfaces of 0 and 11 are the same. Note that the diameters of the two mounting holes provided in the moving side permanent magnet 10 and the presser foot 10b are larger than the diameter of the support rod 10a. The reason for this is that the reduction in the pitch of adjacent support rods 10a due to bending of the belt 1 when passing through the pulley portion is absorbed by the play between the support rods 10a and the mounting holes. Further, the width of the pulley is limited so that the moving permanent magnet 10 does not interfere with the moving permanent magnet when passing through the pulley portion.

る。 Next, the operation of the continuous casting apparatus using the belt will be specifically explained. When the moving permanent magnet 10 moves together with the belt 1 and enters the area where the stationary permanent magnet 11 is located near the magnetic mold surface, it receives an outward repulsive force. The outward repulsive force that the moving permanent magnet 10 receives is transmitted to the belt 1 via the support rod 10a,
The belt 1 is tensed in the width direction, and the deflection of the belt 1 is corrected. At this time, since the moving permanent magnet 10 is arranged on the outside and the stationary permanent magnet 11 is arranged near the center of the belt 1, the tension applied to the belt 1 is well balanced. In addition, even if an imbalance occurs in the magnetic repulsion forces generated on both sides of the belt 1, the gap between the magnetic poles should be widened on the side where the repulsion force is large, and the gap between the magnetic poles should be narrowed on the side where the repulsion force is small. As the belt moves, the repulsive force of the former decreases and the repulsive force of the latter increases, so that the belt 1 is finally stabilized in a balanced position.

Extend the tip of the arm from near both side edges of the belt toward the center of the belt, and attach a fixed permanent magnet to the tip of the support arm so that it is aligned with the outward magnetic pole face of the fixed permanent magnet. The inward facing magnetic pole face of the moving side permanent magnet, which has the same polarity as the magnetic pole face, is placed in close opposition to it, and a magnetic repulsion force that pulls the belt in the left and right direction is generated, resulting in deflection in the width direction due to thermal deformation of the belt. productivity,
