Description

Technical Field

[0001] The utility model relates to the technical field of metal continuous casting equipment, in particular to a direct rolling roller steel separation device. Background Art

[0002] With the development of continuous casting technology in the metallurgical industry, the direct rolling method of continuous casting billets is one of the effective means of energy conservation and efficiency improvement in rod and wire production lines. The direct rolling method of continuous casting billets is a production method in which the billets produced by the continuous casting machine are cut into fixed lengths and then directly sent to the rolling mill for rolling through a series of roller conveyors under high temperature. The small square billet continuous casting machine matched with the rod and wire production line has a large number of streams and a large output, and can supply two rod and wire production lines for production at the same time.

[0003] In the continuous casting slab direct rolling method: Figure 1 As shown, a roller steel separation device is provided behind the billet discharge roller table 1 of the multi-strand continuous casting machine, and the roller steel separation device includes a steel separation roller table 2, a steel separation blocking arm 3 and a first driving mechanism 4. The first driving mechanism 4 can drive the steel separation blocking arm 3 to rotate around a vertical rotating shaft 5. The rear of the roller steel separation device is connected with the first straight rolling production line roller table 6 and the second straight rolling production line roller table 7. The billet discharge roller table 1 delivers a billet to the roller steel separation device each time. When the roller steel separation device receives a steel incoming signal, the steel separation blocking arm 3 swings to the left limit position or the right limit position, and the first straight rolling production line roller table 6 or the second straight rolling production line roller table 7 is moved.

[0004] The disadvantage of the existing roller steel separation device is that the roller steel separation device needs to alternately convey the billets to the first straight rolling production line roller 6 and the second straight rolling production line roller 7, and the steel separation arm 3 needs to swing once for each billet conveyed. The steel separation arm 3 and the first drive mechanism 4 operate very frequently, and the roller body of the steel separation roller 2 is very long, and the stroke of the steel separation arm 3 is very large, which increases the load on the equipment. The long-term operation of the steel separation arm 3 and the first drive mechanism 4 has a high equipment failure rate, and it is impossible to ensure the continuous production of direct rolling of the two production lines.
