Compared with the general galvanized flat steel, the ground non-slip galvanized flat steel has a tooth profile and a symmetrical I-shaped cross section. Deformation characteristics of the tooth profile. The tooth profile is equipped with a vertical roll forming at the front hole of the finished product. During forming, because the reduction of the tooth position is much higher than the reduction of the tooth top position, the uneven deformation causes a drum shape on both sides of the groove bottom. , When the front end of the finished product hole is flat rolled, the amount of metal material in part of the drum changes to part of the width, which promotes the tooth profile of the finished product after rolling and the tooth profile set in the front vertical rolling hole of the finished product to have large teeth. Pitch, this pitch is also changed with the change of the reduction of the finished hole and the front hole of the finished product. To obtain the appropriate tooth profile, it is necessary to effectively clarify the reduction of the finished product hole and the front hole of the finished product and the plate hole design plan, grasp the regularity of deformation, and consider the product regulations in the design plan, which can stabilize the quality and carry out mass production. The front hole roll tooth profile of the finished product.
