Embodiment 1

[0018] Embodiment 1: as figure 1 As shown, a production equipment for continuous casting and rolling of long profiles, including continuous casting machine 1 and billet roller table 2 connected in sequence, the end of billet roller table 2 is provided with a first thermal insulation transition stand connected in sequence 3. The first induction heating device 4 and the rolling mill 5; the billets pulled out from the multi-strand continuous casting machine 1 run parallel on the billet roller table 2 in multiple rows, go to the end of the billet roller table 2, and move horizontally to the first heat preservation The transition stand 3 is sent to the rolling mill 5 for rolling after being heated by the first induction heating device 4 according to the production rhythm.

Embodiment 2

[0019] Embodiment 2: as figure 2 As shown, the difference from Example 1 is that a cooling bed 6 is provided on one side of the end of the billet roller table 2, and a second heat preservation transition stand is provided between the first heat preservation transition stand 3 and the first induction heating device 4 9. The second heat preservation transition stand 9 is also connected with the second induction heating device 8 and the feeding stand 7 in sequence; Heated by the second induction heating device 8, passed through the second heat preservation transition stand, heated twice by the first induction heating device 4 and then rolled.

Abstract

The invention relates to a continuous casting and rolling production equipment of long profiles. The equipment comprises a continuous casting machine (1) and an ejection roller table (2) which are connected sequentially and is characterized in that: one side of the end part of the ejection roller (2) is provided with a first heat preservation transition rack (3), a first induction heating device (4) and a rolling mill (5) that are connected sequentially; and continuously cast blooms are transited by the first heat preservation transition rack (3), then sent to the first induction heating device (4) one by one for concurrent heating and finally rolled by the rolling mill (5). The equipment improves the former production mode that a heating furnace is used for heating the continuous cast blooms in the production of long profiles, saves investment in the heating furnace, fuels and fuel generating and delivering equipment, reduces labor capacity, energy consumption and production cost, and can be widely applied to the rolling production of long profiles.

Description

technical field [0001] The invention belongs to the technical field of molding, and relates to continuous casting and rolling equipment, in particular to a production equipment for continuous casting and rolling of long profiles. Background technique [0002] At present, the commonly used long section production method is that the billet is pulled out from the continuous casting machine and then unloaded from the cooling bed, transported to the loading section of the rolling workshop, and then sent to the heating furnace for heating after being loaded, or the billet is pulled out from the continuous casting machine and passed through a heating furnace. The roller table is directly transported to the heating furnace of the rolling workshop for heating, so that the billet can keep a certain temperature before entering the heating furnace, which greatly saves fuel consumption. Continuous casting and rolling is currently recognized as an economical and effective production proce...
