Description

The present invention relates to continuous casting molds.

A continuous casting mold is formed in a rectangular frame shape by sandwiching a pair of short side members at both ends of a fixed long side member and a movable long side member that face each other. can be cast as
In the continuous casting mold, it is possible to cast slabs having different thicknesses by changing the widths of both short side members.

Some continuous casting molds are equipped with an electromagnetic brake, which slows down the flow of molten steel by applying an electromagnetic force to the molten steel as it passes through the continuous casting mold.
In a continuous casting mold equipped with an electromagnetic brake, the core of the electromagnetic brake is supported by a fixed frame, and its tip is placed with a slight gap (about 5 mm) between the long side member on the moving side and the magnetic flux so as not to interfere. . Therefore, if the moving-side long-side member is temporarily moved away from the fixed-side long-side member during replacement of the short-side member, the core and the moving-side long-side member interfere with each other, causing the short-side member to move away from the fixed-side long side member. Lack of working space for component replacement.

On the other hand, in the continuous casting mold of Patent Document 1, the core of the electromagnetic brake can be moved in the moving direction of the moving side long side member, and even if the moving side long side member is moved, it does not interfere with the core. The work space necessary for exchanging the side members is provided.
Specifically, a fixed-side core whose base penetrates the fixed frame and whose tip is arranged on the back side of the fixed-side long side member, and whose base penetrates the fixed frame and whose tip is the movable-side long side member. a moving core arranged on the back side and movable along the direction of movement of the moving long side member; A drive section is provided for moving the side core relative to the fixed frame along the moving direction of the moving side long side member, and the moving side core is moved by the driving section to adjust the distance between the moving side core and the moving side long side member. are adjusting.

According to such a continuous casting mold of Patent Document 1, a working space is obtained by moving the moving side core, and the fixed side long side members and the moving side long side members are attached to the continuous casting equipment (online). It is possible to change the slab thickness by exchanging both short side members.
In addition, since only the moving side core moves among the members constituting the electromagnetic brake, the structure of the electromagnetic brake does not become complicated, and an increase in manufacturing cost can be suppressed.

Long side copper plates for sliding on the slab are installed inside each of the fixed side long side member and the movable side long side member, and a long side cooling box for cooling the long side copper plate is installed inside the long side copper plate. is installed. The long-side cooling box is formed with recessed core accommodating portions, and the tips of the fixed-side core and the moving-side core are inserted into the respective core accommodating portions. As a result, even when the long-side cooling box is provided, the ends of the fixed side core and the moving side core can be brought sufficiently close to the slab, and the electromagnetic force can be reliably applied to the slab.

JP 2009-214143 A

In the above-described continuous casting mold of Patent Document 1, the moving side core is moved by the drive unit in order to adjust the distance between the moving side core and the moving side long side member.
During movement, the base of the moving core and the fixed frame slide, and the tip of the moving core and its supporting portion (for example, the inner surface of the core accommodating portion of the cooling box) slide. Due to the sliding resistance between them, there is a risk that the direction of the moving side core will be tilted obliquely.
In particular, the sliding resistance between the lower surface of the movable core and the fixed frame is large because the movable core bears the weight of the movable core. Can cause significant tilt.
In this way, if the moving core is tilted during movement, the left and right side surfaces of the moving core may slide strongly against the inner side surface of the fixed frame and adhere to each other, preventing the moving core from moving reliably. have a nature. If such poor movement of the moving side core occurs online (in operation), it may lead to serious damage due to long-term production stoppage such as mold replacement, and there has been a demand for improvement.
