Flying shear is used in ferrous and non-ferrous metallurgy enterprise, and is a kind of extremely important and complicated equipment. It can compose the crosscut system with uncoilers, crop shears, disc shears, loops, straightening machines and pilers etc. It can be installed in front of hot tandem mills to cut off the head or tail of irregular rolled pieces from roughing rolling mills, or installed in the out let of finishing rolling mills to cut the rolled pieces into different length as the requirements form buyers. At present, flying shear is widely used in shear line of cold and hot continuous rolling plant.

Flying shear can be divided into QFB L1740 flying shear, QFQ1406 crank tilting flying shear, QFX1802 rotating flying shear, QFX1402 rotating flying shear, QFT0516 pulley flying shear, QFT0525 pulley flying shear, QFT 1201 pulley flying shear and QFY1412 mobile flying shear etc. according to different functions.

NHI has mastered the technology of design and manufacture of flying shear mainly used in China by researching and developing for many years. The mobile flying shear made by NHI for Northeast Light Alloy Co. Ltd., is the biggest specification sizing shearing equipment used into aluminum alloy plate processing presently in China. The pulley flying shear made by NHI for Jilin Midas aluminum Co. Ltd., is the largest, fastest, and highest precision sizing shearing equipment used into aluminum alloy sheet processing presently in China. At present, NHI has mastered the technology of design and manufacture of various specifications flying shears, and makes efforts to the limit capacity of manufacture in China.
