Description

Roller apparatus and casting systems

The present invention relates to a roller device and a casting facility, and more particularly, to a roller device and a casting facility capable of suppressing deformation due to an external force and facilitating maintenance.

In general, cast irons are manufactured while molten steel accommodated in a mold is cooled through a cooling table. For example, in the continuous casting process, molten steel is injected into a mold having a certain internal shape, and the reaction-solid cast slab is continuously drawn to the lower side of the mold to produce semi-finished products of various shapes such as slabs, blooms, billets, and beam blanks. It's fair.

In the continuous casting process, the cast slab is first cooled in the mold, and after passing through the mold, water is sprayed onto the cast slab to secondary cooling, whereby solidification proceeds. Primary cooling is performed in the mold, and the cast iron drawn from the mold is secondarily cooled while passing through a cooling line under the mold. When passing through such a cooling line, pressure is applied to the upper and lower surfaces of the cast steel by the guide rolls of the segments, pressure is applied to both sides of the cast steel by roller devices provided on both sides of the cast steel, and A cooling medium such as cooling water is sprayed onto the cast by the cooling water sprayer.

The cast steel drawn from the mold is not completely solidified, and unsolidified molten steel may exist inside the cast steel. Accordingly, when pressure is applied to the upper and lower surfaces of the cast steel by the guide roll of the segment, the unsolidified molten steel inside the cast steel moves to both sides of the cast steel S, causing a bulging phenomenon in which the sides of the cast steel protrude convexly, or In severe cases, cast iron may burst. Therefore, by providing roller devices on both sides of the cast steel and guiding the side surfaces of the cast steel, the occurrence of such a phenomenon is suppressed.

Such a roller device includes a support body provided to extend in the vertical direction under the mold, and a plurality of roller parts spaced apart from each other in the vertical direction on the support body. In this case, the support may be formed in a plate shape, and a plurality of roller portions may be fixedly installed on a bracket provided on one surface of the support.

However, since the support body of the roller device is formed in a plate shape, there is a problem that the impact generated when the roller unit contacts the cast piece is transmitted as it is and is easily deformed. When the support is deformed in this way, the position of the roller connected to the support is also changed, so that the side surface of the cast steel cannot be properly guided, or the roller part cannot rotate properly, causing defects on the surface of the cast steel.

In addition, when the cast iron burst occurs, molten steel flowing out of the cast steel may be attached to the entire roller part as well as the plate-shaped support. In this case, the support body is thermally deformed by the heat of the molten steel, and as the molten steel solidifies, problems such as the need to repair or replace the entire roller device may occur by forming a metal core on the roller as well as the support.
