Description

Technical Field

[0002] Hot-rolled strip coiling guide device is used to locate the position of hot-rolled strip coiling and facilitate the guidance of hot-rolled strip coiling. Hot-rolled strip, also known as hot-rolled steel strip, commonly known as hot plate, is generally 1.2 to 8 mm thick. Strips with a width of less than 600 mm are called narrow strips, and those exceeding 600 mm are called wide strips. Hot-rolled steel plates are divided into structural steel, low-carbon steel, and welding bottle steel. Hot-rolled steel plates have low hardness, are easy to process, and have good ductility. Hot-rolled strip products include steel strips and steel plates sheared therefrom. Steel strips can be divided into straight coils and finishing coils.

[0003] For example, a hot-rolled strip coiling and guiding device provided in the Chinese patent application with application number 202120088237.5 includes: a base; a support plate, arranged at the top left end of the base; a motor frame, installed in the middle position on the left side of the support plate; a DC motor, installed at the top of the motor frame; a roller, one end of which is rotatably installed on the right top end of the support plate and fixedly connected to the output end of the DC motor; a strip flattening mechanism, installed at the top front end of the base; a steel coil diameter detection mechanism, installed at the top rear end of the base; a support rod, rotatably installed on the right top end of the steel coil diameter detection mechanism, and the other end of the roller is adapted to be plugged into the top front end of the support rod.
