- one of the long-side frames is fixed and the other is movable, but it is theoretically possible to make both movable.
- the long side frame is an important equipment for producing one piece of pass line, and it is preferable to fix one of them for quality control such as dimensions and shape, because it is easier to center when replacing the mold.
- the method of the present invention is suitable for continuous production of slabs.
- the most effective application of the slab to the continuous structure is a slab having a width of 800 to 250 mm in a preferred range, but is not limited to this range.
- the thickness of the present invention has a wide degree of freedom due to the properties of the present invention, it is generally used in a range of 200 to 300 mm.
- the present invention is particularly effective for continuous manufacturing equipment having many types of thickness.

- the part of the upper end pin 21 that engages with the concave part 15 is a prism of about 5 Oram on one side (with chamfer), and the other part and the lower end pin 24 are about 60 mm in diameter. It was cylindrical.
- the change of the set thickness of the conventional mold was realized by suspending the mold body by a crane and resetting the mold instead of setting a short-side frame of a different thickness in advance. For this reason, it took about 90 minutes to replace the crane due to the setup time of the crane, the removal of all covers, etc., and the waiting time for measures against steam during lifting.
- the required time is less than 30 minutes (approximately 15 minutes for one side), and the time is greatly reduced.
- operators did not remove the power par etc., so steam etc. did not rise, so the operator evaluated that the working environment was improved.
- connection mechanism between the short side frame and the moving device has a concave structure, and has a fixed system that can be easily mounted and dismounted, so that the short side frame can be exchanged online easily and in a short time. Therefore, the mold thickness can be changed in a short time.
- the short side frame has an integral structure, there is no worry about poor sealing of cooling water between the front and back surfaces of the short side frame as compared with the conventional split-exchange type.
- the present invention can be applied even when modifying an existing continuous molding mold without reducing the width of the slab that can be produced.
