Example Embodiment
[0049] Example one:
[0050] The production process sequence according to the present invention includes: continuous casting by a continuous casting machine, cutting to length of the continuous casting billet, parallel flow of the continuous casting billet, heat preservation and buffering of the casting billet heat preservation device, electromagnetic induction heating, rolling mill rolling, cooling collection. Combine Figure 7 As shown, the process is as follows:
[0051] (1) High-speed continuous casting: using high-speed continuous casting technology for sequential multiple-strand continuous casting, the section size of the continuous casting billet is 165mm×165mm, the continuous casting speed is 3.6m / min, the number of continuous casting streams is five, and the hourly output is 230t / h;
[0052] (2) Cut to length of continuous casting billet: After cooling in the second cooling section of the continuous casting sector and straightening by the stretching and straightening machi...
