[0069] The invention provides a strip steel descaling production line, such as figure 1 As shown, the production line includes: uncoiler 1A, straight head leveler 3A, strip steel descaling system 60A, strip steel cleaning device A9, drying equipment 10A, coiling turning roll 19A arranged in sequence along the strip forward direction 100A and coiler 17A; the strip descaling system 60A includes: the first S-shaped tension roller mechanism 71A arranged in sequence along the strip advancing direction 100A, the scale-breaking tension leveler 6A, the second S-shaped tension roller mechanism 72A and sand blasting In the descaling machine 8A, the strip can pass through the first S-shaped tension roller mechanism 71A and then enter the scale-breaking and straightening machine 6A. After the roller mechanism 72A, it enters the sand blasting and descaling machine 8A.

Embodiment 3
[0094] The inventor has studied the steel strip descaled by spraying steel grit, and found that: during descaling, after the steel grit peels off the iron oxide scale of the strip steel, some tiny grains of steel grit are embedded on the surface of the steel strip. The high-pressure water has a great pressure and can remove most of the steel grit and dirt on the surface. However, when descaling, the spray force is very large when using steel grit to remove oxides on the surface of the strip, and some tiny particles are embedded in the surface of the strip. Difficult to get the particles out.
[0095] For this reason, the invention provides a kind of strip cleaning device, as Figure 5a and Figure 5b As shown, the strip cleaning device comprises: a casing 100, which is provided with a strip inlet 11 and a strip outlet 12, and the feeding direction 13 in which the strip enters the casing 100 is along the strip inlet 11. Pointing to the strip steel discharge port 12; at least ...
