The No.1 flying shear is a key equipment on the steel rolling production line, mainly used to shear high-temperature rolled pieces in motion to meet different production needs. Here is a detailed introduction:

1.  Equipment overview

The No. 1 flying shear is usually installed at the front of the steel rolling production line. After the initial rolling of the steel billet or steel, it is cut to length or subjected to head and tail cutting treatment. It consists of the main mechanical structure, transmission system, control system, and other parts. The mechanical structure includes a cutting blade, a knife holder, a frame, etc. The transmission system is generally driven by an electric motor and transmits power through components such as gears and couplings. The control system is responsible for accurately controlling the timing, position, and speed of cutting to ensure cutting accuracy.

2.  Working principle

When the rolled piece enters the working area of the No.1 flying shear through the conveyor roller, the detection devices installed next to the roller (such as photoelectric sensors and hot metal detectors) will monitor the position and running speed of the rolled piece in real time. The control system calculates the optimal cutting timing based on the preset cutting length and process requirements, and quickly issues instructions when the rolled piece reaches the designated position. The transmission system drives the cutting blade to quickly close and complete the cutting process during the rolling process, dividing it into lengths that meet the requirements or removing irregular parts at the head and tail.

3. Function and significance

The No.1 flying shear is crucial in steel rolling production. On the one hand, it can remove the unqualified parts caused by uneven temperature and poor deformation at the head and tail of the rolled piece, and improve the quality and yield of subsequent rolling. On the other hand, the rolled pieces can be cut into specified lengths according to the process requirements, providing qualified billets for subsequent processes such as precision rolling and coiling, ensuring the continuity and efficient operation of the entire production line.

The No.1 flying shear, with its efficient and precise cutting ability, has laid a solid foundation for the stability of steel rolling production and the improvement of product quality, and is an indispensable important equipment in the modern steel industry.
