Abstract
The invention discloses a vertical circular billet continuous casting machine dummy bar which is a rigid dummy bar device capable of producing ingot castings continuously for a large vertical section (phi ranging from 800 to 1200mm) circular billet continuous casting. The dummy bar is of a hollow circular stem section structure. The vertical circular billet continuous casting machine dummy bar comprises a dummy bar body stem section, a dummy bar head, a dummy bar head stem section, a connecting piece and a dummy bar head locking device, and further comprises well-known T-shaped bolts. The dummy bar body is a plurality of circular hollow stem sections, the upper end portion and the lower end portion of each stem section are provided with spigots, each stem section is internally provided with a flange plate, bolt holes are evenly distributed in each flange plate, and the adjacent stem sections are fixedly connected through connecting bolts via the bolt holes. The dummy bar body stem section, the dummy bar head stem section and the dummy bar head are fixedly connected through the T-shaped bolts. Vertical locking bolts and horizontal locking bolts are arranged between the dummy bar head stem section and the dummy bar head to connect and lock the dummy bar head and a dummy bar head rod section. The dummy bar body and the dummy bar head stem section are connected and locked through connecting bolts. The vertical circular billet continuous casting machine dummy bar is simple in structure and light in weight, and the dummy bar head is replaced easily.
Description
technical field [0001] The invention relates to a dummy bar device for a vertical round billet continuous casting machine, in particular to a dummy bar used in the continuous casting production of a vertical large section (φ800-1200mm) round billet, belonging to the technical field of continuous casting equipment in the metallurgical industry . Background technique [0002] With the rapid development of my country's heavy equipment manufacturing industry, large billets (such as: round billets above φ800, rectangular billets with a thickness of more than 500, and slabs with a thickness of ) The market demand is gradually increasing, mainly used to manufacture core components of industries such as national defense, electric power, and shipbuilding. The vertical continuous casting machine is more suitable for the continuous production of this large special billet. It has the advantages of better casting billet surface quality and inner quality than the arc machine, and the inne...
