Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical rolling, in particular to a continuous casting billet rough rolling device. Background Art

[0002] Rough rolling is the initial processing of a blank. Larger rolling rolls are typically used in this process, primarily to remove imperfections such as pores and wrinkles from the raw metal billet to facilitate subsequent processing. Rough rolling allows for a larger thickness and width, while being simple to operate. It is commonly used to produce blanks for intermediate and finishing rolling.

[0003] The precursor process to rough rolling is continuous casting. The hardness of the produced steel billet is greatly improved after water cooling treatment. For example, Chinese patent publication No. 210253551U discloses a short-process long product headless rolling production line, which enters the rough rolling unit after being processed in the straightening machine. Since the temperature of the steel billet bar has been reduced at this time, the difficulty of rough rolling is increased. Utility Model Content
