However, increasing the coiling temperature of high-strength steel will greatly shorten the life of the reel. At the same time, due to the emergence and extensive use of ultra-high-strength steel plates in recent years, the practice of only increasing the coiling temperature can no longer meet the production requirements of ultra-high-strength steel plates. , unwinding accidents still occur frequently

Embodiment Construction
[0031] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0032] An unwinding device for preventing unwinding of high-strength steel coils, such as figure 1 As shown, it includes an unwinding device 1, an inner diameter pressing device 2 and an outer diameter pressing device 3 that can reciprocate along the axis of the reel;
[0033] like figure 2 As shown, the unwinding device 1 is used to support and transport the steel coil to the baling saddle. Right below the reel, the unloading car track 1-1 is equipped with an unloading car 1-7, wherein the unloading car 1-7 includes an unloading car frame 1-2, and the unloading car frame 1- 2. There are rollers 1-4 that can be used in conjunction with the track 1-1 of the unloading car, and the frame 1-2 of the unloading car is also equipped with a lifting cylinder 1-3 for the unloading car, and a lifting cylinder 1 for the unloading car. -3 The telescopic...

The invention discloses a coil unloading device capable of preventing loosening of a high-strength steel coil. The coil unloading device comprises a coil unloading device body capable of moving back and forth in the axial direction of a winding drum, an inner diameter pressing transport winding vehicle and an outer diameter pressing device; the coil unloading device body is used for supporting thesteel coil and conveying the steel coil to a bundling saddle; the inner diameter pressing transport winding vehicle is used for pressing the steel coil along the inner diameter of the steel coil andtransporting the steel coil from the bundling saddle to a transport chain tray; and the outer diameter pressing device is used for pressing the steel coil along the outer diameter of the steel coil. The coil unloading device capable of preventing loosening of the high-strength steel coil can prevent the steel coil from being loosened during steel coil unloading and is suitable for high-strength steel plates with different specifications, the service life of the winding drum is prolonged, the economical environment-friendly effect is achieved, and the equipment investment and maintaining cost can be reduced.
Description
technical field [0001] The invention belongs to the technical field of metallurgical rolling devices, relates to an unwinding device for preventing the unwinding of high-strength steel coils, and also relates to an unwinding method for preventing unwinding of high-strength steel coils. Background technique [0002] In the production process of hot-rolled high-strength steel, due to the high tensile strength of high-strength steel, when the hot-rolled steel coil is unloaded from the reel of the coiler, when the steel plate exceeds a certain specification, it is easy to loose coil. This is a common problem encountered by people in the industry. [0003] At present, in order to prevent the unwinding of the steel coil during unwinding, the temperature of the high-strength steel plate during coiling is usually increased. However, increasing the coiling temperature of high-strength steel will greatly shorten the life of the reel. At the same time, due to the emergence and extensi...
