Abstract

The invention discloses a guide groove for a rolled piece of wire rod and a method for preventing scratches of the rolled piece of wire rod. The guide groove of the rolled piece of wire rod includes a guide groove base, and a guide groove for the rolled piece of wire rod to pass is arranged inside the guide groove base , a free-rotating guide roller assembly is provided at one end of the base of the guide groove. The guide roller assembly includes guide roller I, guide roller II and guide roller III. Guide roller I is connected to the guide groove cover plate through a bracket. The guide roller II and the guide roller III are arranged symmetrically on the guide groove base, and one end of the guide groove can freely rotate along the guide groove base. The guide groove is a U-shaped groove structure, and the guide rail formed by the corresponding guide roller II and the guide roller III for the wire rolling piece to pass is a U-shaped groove structure, and the guide roller I is arranged at the opening end of the U-shaped groove structure of the guide rail. Installing the wire rod rolling piece guide groove at the climbing point of the straight line section of the rolling line has changed the traditional friction form between the four sides of the wire rolling piece and the guide groove at the climbing point, that is, changing from sliding friction to rolling friction, reducing the friction of the wire rod rolling piece. Mechanical scratches / scratches during rolling improve the surface quality of the finished product.

Description

technical field [0001] The invention belongs to the technical field of steel rolling, and in particular relates to a guide groove of a rolled piece of wire rod and a method for preventing scratches of the rolled piece of wire rod. Background technique [0002] At present, the guide grooves used in the high-speed wire rolling lines of most steel mills are commonly used sliding guide grooves. This kind of sliding guide grooves can basically meet the needs of construction wire rods, but cannot meet the needs of high value-added special steel. The technical level and usage requirements on the slope. Especially for cold heading steel, spring steel, cord steel and other wire products with high surface quality requirements, the use of commonly used sliding guide grooves on curves and climbing slopes has been unable to meet customers' requirements for cold heading steel and subsequent wire rolling. process requirements. [0003] According to research, when there are pits greater t...
