Problems solved by technology

[0002] In the production process of the hot-rolled tempering unit and the pickling unit, the surface of the product strip (that is, the hot-rolled plate) is attached with scale, which not only reduces the surface quality of the finished product, but also causes high equipment loss due to scale and dust. It not only increases the cost consumption of production enterprises, but also causes environmental pollution and health damage to operators, which is another problem that plagues steel production enterprises
Although most hot-rolling and tempering units are equipped with expensive dust removal systems, due to the low matching degree between the configured dust removal system and the dust generated during the production of the unit, and due to Oxidized iron scale fragments and dust, the configuration of the dust removal system is not targeted, resulting in a situation where a large amount of money cannot be solved

Embodiment 1

[0017] Such as figure 1 , figure 2 , image 3 As shown, the method for improving the product surface quality of the hot-rolled leveling unit is to carry out transverse bending (such as Figure 4 , Figure 5 As shown, the width direction of the strip is horizontal, and the length direction of the strip is vertical), peel off the iron oxide scale attached to the surface of the strip; then blow air on the surface of the strip on one side of the strip, and blow the peeled iron oxide towards On the other side of the steel, the peeled iron oxide scale is sucked away by the vacuum hood arranged on the other side of the strip.

[0018] Transverse bending is realized by scale removal device, which includes scale removal support 11, hydraulic cylinder 12, support frame 13, transverse bending pressure roller 14, the left end of support frame 13 is hinged with scale removal support 11, and the support frame The upper right end of 13 is hinged with the piston rod of the hydraulic cyli...

Embodiment 2

[0021] It is basically the same as Embodiment 1, the difference is that: after the strip between the uncoiler 1 and the entrance turning pinch roller 3 is transversely bent, and before the strip surface is blown, the strip is longitudinally bent. bending (such as Figure 6 , Figure 7 As shown), the iron oxide scale attached to the surface of the strip is peeled off.

[0022] Short longitudinal bending rollers 17 are arranged at both ends of the transverse direction (the width direction of the strip is the transverse direction) for the longitudinal bending of the strip, so that the longitudinal bending of the strip is carried out, and the oxide scale is further detached from the strip.

Abstract

The invention relates to a method for improving the surface quality of a hot-rolling planishing mill set product, which is applied to the hot-rolling planishing mill set and can also be applied to an acid washing machine set. The method for improving the surface quality of the hot-rolling planishing mill is characterized in that strip steel between an uncoiler and an inlet steering pinch roll is transversely curved first in the planishing process of the hot-rolling planishing mill set on the strip steel, and iron scales attached to the surface of the strip steel are peeled off; and the surface of the strip steel is subjected to air blowing on one side of the strip steel, and the peeled iron scales are blown to the other side of the strip steel and sucked away by a dust suction hood which is arranged on the other side of the strip steel. The method obviously improves the surface quality of products, is simple and has low cost.
