Embodiment Construction
[0031] This embodiment provides a specific embodiment of the device for removing residual water on the surface of a plate and strip roller quenching of the present invention, such as figure 1 , 2 As shown, choose 80mm thick, 2500mm wide, 8m long plate and strip as an example to illustrate the implementation process. After the head of the plate and strip 1 leaves the heat treatment furnace 2 and reaches the front end of the high-pressure cooling zone 4 of the roller quenching machine 3, the air blowing nozzle 6 at the front of the high-pressure cooling zone is opened, the air injection pressure is 0.4-0.6MPa, and the air injection flow rate is 10Nm 3 / min, air injection time 2min, when the tail of the plate and strip 1 leaves the front end of the high-pressure cooling zone 4 of the roller quenching machine 3, the air blowing nozzle 6 at the front of the high-pressure cooling zone is closed. When the head of the strip 1 reaches the end of the high-pressure cooling zone 4 of the ...
