Rotary Flying Shear

The 2# flying shears is a hot shears. The rotary flying shear is located in front of the finish rolling mill, and normally in front of the 13H rolling mill gearbox.

Rotary Flying Shear


The 1#, 2#, and 3# flying shears belong to hot shears and are a type of flying shear machine. They are mainly used in the bar, wire rod and section steel production lines of steel mills to cut the heads and tails of rolled pieces, conduct emergency fragmentation and segment them into multiple lengths.

The flying shears designed and manufactured by TINVO can meet the requirements of modern rolling technology for large rolling sections and high rolling speeds. We can conduct customization according to the actual needs of customers to meet the individualized rolling technology requirements, such as flying shears for channel steel, angle steel, and other section steels.


Classification and Main Parameters
According to the different layout positions and shearing specifications of the flying shears in the steel mill, they are divided into 1# flying shear, 2# flying shear, and 3# flying shear.
· The 1# flying shear is located in front of the medium rolling mill, and normally in front of the 7H rolling mill gearbox.
· The 2# flying shear is located in front of the finish rolling mill, and normally in front of the 13H rolling mill gearbox.
· The 3# flying shear is located after the finish rolling mill, generally behind the 18th stand.
