Problems solved by technology

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

Abstract

The invention discloses a coil unloading device capable of preventing high-strength steel coil loosening. The device comprises a coil unloading device capable of performing a reciprocating motion in the axial direction of a drum, a pressure inner diameter coil carrying car and a pressure outer diameter device; the coil unloading device is used for supporting and conveying steel coils to a bundlingsaddle base; the pressure inner diameter coil carrying car is used for pressing the steel coils from inner diameters of the steel coils and conveying the steel coils from the bundling saddle base toa transportation chain tray; and the pressure outer diameter device is used for pressing the steel coils from the outer diameters of the steel coils. The coil unloading device capable of preventing high-strength steel coil loosening can prevent loosening of the steel coils during unloading, can be suitable for high-strength steel plates with any specifications, prolongs the service life of the drum, achieves both economy and environmental protection, and reduces the equipment investment and the maintenance cost.

Description

Technical field [0001] The invention belongs to the technical field of metallurgical rolling devices, and relates to a coil unloading device for preventing high-strength steel coils from loosening. 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 coiler drum, loose coils are likely to occur when the steel plate exceeds a certain specification This is a problem commonly encountered by people in this industry. [0003] At present, in order to prevent the unwinding of the steel coil during unloading, it is usually used to increase the temperature of the high-strength steel plate during the unwinding. Increasing the high-strength steel coiling temperature will greatly shorten the life of the coil. At the same time, due to the emergence and large-scale use of ultra-high-strength steel plates in recent years, only increasing the coiling t...
