Abstract

The invention discloses a vertical continuous casting production device and method for round billets of an extra large specification. The vertical continuous casting production device for the round billets of the extra large specification comprises a steel ladle (1), a middle tank (4), a crystallizer (6), a billet pulling system and a billet discharging system. The billet discharging system comprises a casting billet discharging device (20), a casting billet combining device (23), a casting billet lifting device (25) and an upper billet discharging roller bed (28). The vertical continuous casting production device and method for the round billets of the extra large specification are mainly applied to the round billets with the extra-large-specification sections with the diameter being 600mm-1300 mm, the brand new technologies of the billet pulling system, the billet discharging system and the like are adopted, multiple matched technological devices are adopted, and therefore the vertical continuous casting process method is suitable for producing a variety of steel like carbon steel and alloy steel, especially medium-and-high alloy clean steel and steel with high casting crack sensitivity, and continuous production of large-section high-quality billets is achieved.

Description

technical field [0001] The invention relates to the technical field of iron and steel smelting, in particular to a vertical continuous casting production equipment for a super-large round billet, and a vertical continuous casting method for a super-large round billet. Background technique [0002] With the development of the steel downstream manufacturing industry, material processing and other industries, based on the market demand for reducing material consumption and shortening the processing process, the market for large and medium-sized premium special steel round billets that are cast instead of ingots continues to expand. The industrialized production and development of high value-added blanks such as clean steel and high casting crack sensitivity are gradually becoming the focus of the industry, and will become a high-end field of special material production. [0003] Large-sized round slabs have high requirements for the homogeneity of the internal quality of the sl...
