1.Scope of Application Flying shear is one of the large-scale equipment used in nonferrous metallurgy and ferrous metallurgy enterprises. It forms a cross cutting unit with uncoiler, cutting shear, disc shear, looper, straightener, plate stacking platform and other equipment, or is installed in front of the hot continuous rolling unit to cut off the head or tail of the irregular rolled piece produced by the rough rolling unit, so as to reduce the impact of the rolled piece on the finishing mill or damage the roll of the finishing mill; Or it can be installed at the outlet of the finishing mill of the continuous rolling mill to cut the rolled pieces from the finishing mill into different lengths to meet the needs of different users. At present, flying shear is widely used in the shear line of cold and hot rolling mills. 2.Specification Name: mobile flying shear Shearing product thickness (mm): 2mm ~ 12mm 3.Product Introduction Due to its different functions, it can be divided into QFB-L1740 swing flying shear, QFQ1406 crank swing flying shear, QFX1802 rotary flying shear, QFX1402 rotary flying shear, QFT0516 roller flying shear, QFT0525 roller flying shear, QFT1201 roller flying shear, QFY1412 mobile flying shear, etc. Through years of research and development, our company has mastered all types of flying shears currently used in the mainstream in China. Among them, the mobile flying shears produced by Northeast Light Alloy Co., Ltd. are the mobile fixed length shears for aluminum alloy thick plates with larger specifications, while the roller flying shears produced by Jilin Midas Aluminum Co., Ltd. are the fixed length shears for aluminum alloy thin plates with the largest specifications, the highest accuracy and the fastest speed. At present, our company has mastered the design and manufacturing capacity of various specifications of flying shear equipment, and is striving for the domestic extreme manufacturing. 4.Main Experiences in Recent Years Northeast Light Alloy, Jilin Midas Aluminum Project, etc
