Beschreibung
Zusammenfassung:	Disclosed are a top hat steel rolling method and a top hat steel. The process flow of the present rolling comprises: heating → high-pressure water descaling → cogging and blank rolling → reciprocating continuous rolling → cooling → straightening. Rolling hole shapes comprise a wavy flat arc-shaped pre-cut split hole, an M-shaped top hat-typed split hole, a top hat-typed finish rolling hole, and a hot-rolled finished hole. The middle portion of the top hat-typed finish rolling hole and the hot-rolled finished hole has an arc-shaped section. An upper leg portion and a lower leg portion are symmetrically provided at two ends of the arc-shaped section. An included angle is formed between the upper end of the upper leg portion and one end of the arc-shaped section. The lower leg portion is arranged at a lower end of the side of the upper leg portion away from the arc-shaped section, and the lower leg portion intersects with the upper leg portion to form an included angle. The top hat steel comprises a horizontal w
