[0042] In the utility model, the swing drive portion 4 that can drive gas mist cooling lower header part 3 swing and lift in the overhaul space 101 is arranged below gas mist cooling roller way 1, so that gas mist cooling lower header part 3 can be stably swung down to the vertical direction during overhauling, and the overhaul height is flexibly adjustable, so that it is not necessary to lift gas mist cooling roller way 1 again, and the maintenance personnel can directly install, check, repair and replace the header nozzle and other work below, which not only improves the work efficiency, but also reduces the operation difficulty and safety risk. Meanwhile, it also reserves sufficient operation space and interface for possible future technical upgrading and maintenance requirements, and provides strong support for the continuous optimization and upgrading of the thin strip casting and rolling process.

[0043] After gas mist cooling lower header part 3 is safely lifted and stably placed, the end thereof is provided with locking portion 5 (locking device), and the main function of locking portion 5 is to mechanically lock gas mist cooling lower header part 3, so that gas mist cooling lower header part 3 is clamped in the horizontal position, and the stability and reliability thereof during daily work are ensured, so as to meet the continuous and efficient production requirements.

[0045] The dismounting process of the gas mist cooling header in the prior art is complex and time-consuming, which brings inconvenience to equipment maintenance.

[0046] The utility model solves multiple technical problems faced by the gas mist cooling equipment in the thin strip casting and rolling process. In the traditional technology, the dismounting process of the lower header is complex and time-consuming, which brings inconvenience to equipment maintenance. Now, through the improved design, the dismounting of the lower header becomes simple and fast, greatly improving the maintenance efficiency.

The other end of the lower header frame 31 is hinged to a hinged base 33. The gas mist cooling lower header part 3 can run along the safety rail 6, and mechanical limiting is added on both sides to improve safety.

[0049] When the gas mist cooling lower header part 3 recovers from the maintenance state to the normal state, or vice versa, due to its large mass, it is easy to deviate during movement. This phenomenon is not only difficult to predict and control, but also causes damage to the swing driving part 4, which is often irreversible, and in severe cases may even cause safety accidents, posing a serious threat to personnel and equipment. In order to effectively deal with this problem, the utility model specially designs a safety rail system, which can balance and stabilize the axial force of the swing driving part 4, thereby effectively preventing the gas mist cooling lower header part 3 from deviating during swinging, protecting the swing driving part 4 from damage, and ensuring the safety and stability of the operation process.

[0054] Further, as shown in Figure 4 , the locking part 5 includes a telescopic locking pin 51, which can be extended and clamped in the header locking hole 36.
