Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] Such as figure 1 As shown, the present invention is a leveling and pickling production line for controlling transverse crease defects, including an uncoiler 1, an inlet shear 2, a welding machine 3, a skin passer 4, an inlet looper 5, and a scale breaker 6 connected in sequence , pickling section 7, rinsing section 8, tension straightening machine 9, export looper 10, export shear 12 and coiler 13.

[0018] It is also possible to add an oiler 11 between the outlet looper and the outlet shear according to the situation, and then carry out an oiling or non-oiling process according to the final product situation.

[0019] In the optimization scheme, a walking beam feeding device is added before the uncoiler 1.

[0020] The technical route adopted is: feeding→uncoiling→shearing→welding→leveling→entry looper→scale breaking machine→pickling→...

Abstract

The invention discloses a leveling and acid pickling production line capable of controlling transverse crease defects, and relates to a metallurgical production line. The leveling and acid pickling production line comprises an uncoiling machine, a pair of inlet shears, a welding machine, a leveling machine, an inlet looper, a descaling machine, an acid pickling section, a rinsing section, a withdrawal and straightening machine, an outlet looper, a pair of outlet shears and a coiling machine which are connected in sequence; and reverse bending rollers are arranged at the back of the uncoiling machine and arranged on the upper rear part of an uncoiling machine drum, and the wrap angle theta of the reverse bending rollers is 35-55 degrees. Compared with the prior art, the leveling and acid pickling production line can reduce the production cost and improve the production efficiency.

Description

technical field [0001] The invention relates to a metallurgical production line, in particular to a leveling and pickling production line suitable for iron and steel smelting enterprises to control transverse crease defects of steel hot-rolled raw materials. Background technique [0002] With the advancement of steel rolling technology, it is possible to "replace heat with heat" for hot-rolled thin-gauge products. The thickness specification of the hot-rolled sheet is extended to 0.7-4.0mm; the hot-rolled raw material coil yields during the uncoiling process of the uncoiler of the existing pickling line, and a cross-bending defect perpendicular to the rolling direction occurs on the surface. The thinner the thickness specification of the raw material coil, the higher the probability of this kind of cross-bending defect, and the more serious the defect is, and the shape of the cross-bending defect on the outer ring is different, there are full width of the coil, and short lin...
