Description

Technical Field

[0001] The utility model relates to the field of the design and use of a dephosphorization water system, in particular to a slab flame cleaning dephosphorization water system. Background Art

[0002] For the slab with sticky steel grade characteristics originally cleaned by the flame cleaning machine, after passing through the dephosphorization water device, there is still a large amount of steel slag remaining on the upper surface of the slab. By increasing the pipe diameter and nozzles of the upper water pipe of the dephosphorization water device, the slag removal effect is remarkable. However, due to the excessive water output on the upper part, there will be a lot of residual water on the upper surface when the hot slab passes through the dephosphorization water device, which will cause excessive deformation of the slab.
