Stainless steel cold-rolled strip steel production device

Abstract

The invention belongs to the field of stainless steel cold-rolled strip steel production and discloses a stainless steel cold-rolled strip steel production device. The stainless steel cold-rolled strip steel production device comprises a raw material uncoiling and welding device, a rolling device, an annealing-pickling device, a flatting and straightening device, an edge portion finishing device and a finished product coiling device which are sequentially connected, wherein raw material coils are sequentially fed by the uncoiling and welding device, head and tail welding of adjacent material coils is achieved, the rolling device rolls the raw material coils according to target thickness, the annealing-pickling device improves the performance of rolled strip steel and obtains strip steel ofthe same surface level, the flatting and straightening device can selectively obtain two types of strip steel of different surface levels, the edge portion finishing device conducts edge trimming onthe strip steel to obtain strip steel consistent in width, and the finished product coiling device coils the strip steel. The stainless steel cold-rolled strip steel production device achieves full continuous production of cold-rolled strip steel, is high in efficiency, low in cost and strong in applicability and makes the produced finished products high in quality consistency.

Description

technical field [0001] The invention relates to the field of stainless steel cold-rolled strip production, in particular to a stainless steel cold-rolled strip production equipment. Background technique [0002] Stainless steel cold-rolled strip steel needs to go through three steps of steelmaking, hot rolling and cold rolling during production. Steel-making slabs are hot-rolled to obtain black coils, then annealed and pickled to obtain white coils (surface grade No. 1), and finally cold-rolled to obtain cold-rolled steel strips. Among them, cold rolling uses white coil as raw material, and after rolling, annealing and pickling, leveling or tension leveling, and edge finishing, cold-rolled strip steel is obtained. [0003] figure 1 It shows the first equipment 100a for producing stainless steel cold-rolled strip in the prior art, which includes a plurality of dispersed independent equipment, which are successively reversible cold-rolling unit 1a, annealing and pickling uni...

AI Technical Summary

Problems solved by technology

However, the equipment 100c for producing stainless steel cold-rolled strip still has the following disadvantages: 1) the weld seam cannot be rolled and smoothed, which affects the overall efficiency and product yield; The bottleneck in the production specifications is obvious; 3) For the edge finishing of steel coils, an edge finishing unit needs to be set up separately; 4) For 2D surface products with high plate shape requirements, a separate tensioning and leveling unit needs to be set up again
