Continuous rolling production line of single-strand flat metal wire

Abstract

The invention relates to a continuous rolling production line of a single-strand flat metal wire. According to the technical scheme provided by the invention, the continuous rolling production line comprises an unreeling machine, at least one calendaring machine, a front cleaning dryer, a speed clutch, an optical thickness-measuring device, an online annealing furnace, an after-cleaning dryer anda measuring reeling device which are sequentially arranged, wherein each calendaring machine, the front cleaning dryer, the optical thickness-measuring device and the measuring reeling device are respectively provided with a speed distributor. The continuous rolling production line of the invention can realize continuous rolling of the flat metal wire so as to greatly improve the productivity; the processed flat metal wire product has high two-dimensional accuracy in width and thickness, the speed distributor can realize accurate distribution of the speeds and ensures the tension balance of the whole production line, and a gap between an upper casting roller and a lower casting roller in the calendaring machine realizes automatic control.

Description

technical field [0001] The invention relates to a continuous calendering production line, in particular to a continuous calendering production line for producing single flat metal wires. Background technique [0002] At present, the domestic production of single-strand flat metal wire mainly includes several methods such as drawing, wide-band cutting and single-strand single-strand calendering. Disadvantages of the drawing method are: the flat wire is less straight and the production speed is lower. The yield of flat metal wire produced by the broadband slitting method is high, but its disadvantages are: there are burrs on both sides of the flat metal wire, and the incision is sharp. Due to the error in the transverse thickness of the broadband itself, the thickness error of the flat metal wire is relatively large. The disadvantage of single-pass single-strand calendering is that flat metal wires with large calendering width and thin thickness cannot be formed at one time,...

Problems solved by technology

Disadvantages of the drawing method are: the flat wire is less straight and the production speed is lower

The yield of flat metal wire produced by the broadband slitting method is high, but its disadvantages are: there are burrs on both sides of the flat metal wire, and the incision is a sharp angle. Due to the error in the transverse thickness of the broadband itself, the thickness error of the flat metal wire is relatively large

The disadvantage of single-pass single-strand calendering is that flat metal wires with large calendering width and thin thickness cannot be formed at one time, and must be calendered repeatedly, because the flat metal wires on the discharge tray for the second calendering are spirally Yes, it is easy to rub the burrs when unloading

In addition, under the premise of ensuring the thickness of the flat metal wire made by repeated calendering, it is difficult to accurately control its width and size, and multiple calendering is also a waste of time, with low efficiency and low production capacity
