If the degree of this rhombic deformation is large, the slab will
Surface cracks at the corners of the slab and internal cracks occur, resulting in the slab becoming defective. In addition, even if the product does not become defective, in the next rolling process, the rolling mill may
When rolling slabs,
This is one of the reasons why the cast slab VI contains mlL.

The tips of the measuring rollers 11.a and 9[) rotate greatly inward or outward. a, ], i b mechanically amplify the displacement. By rotating the tips of the vertical arms 9a, 9b, the horizontal arms 2a, 12b move in the horizontal direction, causing horizontal displacement at the other ends of the horizontal arms 12a, 12b. Therefore, a minute change 11t in the diagonal dimension of the slab 6 in the horizontal direction can be measured by the cage 15 and the indicator 117 as the displacement of the other ends of the horizontal arms 12a, 12b in the water N' direction. The amount of rhombic deformation of the slab 6 can be measured.

Therefore, based on the measured values, the amount of cooling water in the mold, the amount of spray water in the secondary cooling zone, etc.
Continuous casting can be controlled by changing the casting conditions to suitable conditions such as turning and turning, so it is possible to cast Uj pieces with good properties without deformation.
