Embodiment Construction

[0036] The continuous cold-rolled steel strip production line described in the present invention can be divided into uncoiling, welding, positioning, horizontal rolling and vertical rolling, brushing and polishing, rough rolling, heat treatment, finishing rolling, straightening and leveling, winding and packing and other steps.

[0037] (1), uncoiling, can refer to accompanying drawing 3, because what steel strip of the present invention adopts is to form by rolling disc-shaped round steel, in addition, after rough rolling, winding, heat treatment, be disc-shaped steel again Therefore, it is necessary to use an uncoiler to adapt to the subsequent processing flow. The uncoiler of the present invention includes a base 1 and a tray 2 positioning grid 3. A rotating shaft 4 is arranged between the tray 2 and the base 1. The tray 2 can be formed by the rotating shaft. 4. It is supported and rotatable relative to the base. In order to prevent the wire rod (disc-shaped steel strip) fr...

Abstract

The technological process of making cold rolled precise super-narrow steel belt includes the steps of unwinding, welding, positioning, horizontal rolling, vertical rolling, washing and polishing, coarse rolling, heat treatment, finishing rolling, straightening, leveling, winding, packing, etc. The corresponding apparatus includes successively connected unwinder, positioner, leveler, straighener,rolling mill, winding machine, tension regulators, cold rolling emulsion blowing and washing unit, and width and thickness measurer.

Description

field of invention [0001] The invention relates to a method for preparing a cold-rolled precision ultra-narrow steel strip and a device thereof. Background technique [0002] In the prior art cold-rolled precision ultra-narrow steel strip preparation method and device thereof, due to the length of mass production, each time the strip is threaded (that is, the guide wire rod (coil-shaped steel strip) passes through various rolls and processing mechanisms. The process of clearance) is very difficult. The position of the wire rod (disc-shaped steel strip) will swing up and down when it is drawn out. This kind of swing will affect the processing quality if it is light, and the processing cannot continue if it is serious. When winding the steel strip , the guide wheel moves left and right at the ends of both sides of the winding drum, the steel belt will warp in one direction, and the side force will introduce harmful stress to the steel belt, and the introduction of these stress...
