Problems solved by technology
[0007] However, the current research and development of ultra-fast cooling devices are all focused on the research and development of the spray model, and the internal influence of the spray header device itself on cooling has not been paid enough attention, resulting in uneven cooling of the ultra-fast cooling plate , and even lead to insufficient cooling capacity, causing serious defects such as serious buckling, uneven cooling and local deformation at the edge or head and tail of the cooling strip

Embodiment Construction
[0031] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0032] Such as figure 1 As shown, it is a schematic structural diagram of an embodiment of the device for quick closing and adjustment of the ACC spray header of the present invention. This embodiment is used for the quick closing and adjustment of the ACC spray header, including the water guide groove 2 arranged under the spray header 1 and capable of completely covering the spray header 1 and the guides arranged at both ends of the spray header 1 The chute 3 and the water guide trough 2 are installed in the guide chute 3 with a single degree of freedom sliding fit. The drive mechanism of this embodiment includes a drive device 4 fixedly installed on the spray header 1 and a gear transmission mechanism arranged between the spray header 1 and the water guide groove 2, and the gear transmission mechanism of this embodiment includes the driv...

The invention discloses a device for quickly closing and adjusting an ACC spraying header pipe. The device comprises a water guiding groove and a guiding sliding groove. The water guiding groove is mounted in the guiding sliding groove in a unidirection-sliding-matching mode. A driving mechanism used for driving the water guiding groove to slide is arranged between the spraying header pipe and the water guiding groove. Blocking lines used for blocking the spraying header pipe are arranged on edges of a front side and a back side of the water guiding pipe. The blocking lines are multi-point-fitting multinomial parabolic curves which are in axial symmetry and protrude out in one direction. The position of the water guiding groove is adjusted so that cooling water flow can be adjusted, or the spraying header pipe is quickly closed, the blocking lines are set to be the multinomial parabolic curves so that the width flow direction cooling rule of different water flow distribution from the middle portion to two side edge portions of a rolled piece can be actively adapted, and accordingly the rolled piece can be cooled evenly in the width direction, in addition, closing or opening of the spraying header pipe corresponding the head and the tail of the rolled piece is controlled in real time, adjusting of cooling water amount of different zones in a quantitative mode is achieved, and therefore the rolled piece can be in the best cooling state.
Description
technical field [0001] The invention belongs to the technical field of cooling after hot rolling of medium and heavy plates, and in particular relates to a spraying set for controlled cooling of hot rolled medium and thick plates, quenching of strips after rolling, and ultrafast cooling of hot rolled medium and heavy plates. A device for quickly closing and adjusting the tube, which can control the width water crown according to the different characteristics of the strip width cooling. Background technique [0002] With the rapid growth of the national economy, the iron and steel industry has also ushered in rapid development. The iron and steel industry has become a modern supporting industry. The demand for iron and steel will increase for a long time, especially for hot-rolled medium and thick The demand for boards is more, and the requirements for its product quality are higher. [0003] There is still a certain gap between my country's hot-rolled strip cooling control ...
