Embodiment Construction

[0005] The present invention will be further described below in conjunction with accompanying drawing.

[0006] figure 1 It is a structural schematic diagram of the acid-free physical treatment strip scale production line of the present invention.

[0007] Uncoiling: Send the original steel strip without derusting to the upper uncoiler 1 for uncoiling.

[0008] Shearing and butt welding: Cut off the irregular part of the uncoiled strip steel head and tail with a shear welding machine in 2 minutes, and then weld the head and tail of the two packs of materials together to ensure that the strip steel Continuity while walking.

[0009] Looper storage: Send the continuous butt-welded strip steel into the looper 3 for storage to ensure sufficient raw materials for subsequent processes;

[0010] Deviation correction: the strip steel passes through the S-roll tension machine 4, and under the action of tension, the strip steel enters the next process smoothly and evenly, so as to en...

Abstract

The invention belongs to the technical field of steel machining, and relates to a production line for treating a strip steel oxide scale in an acid-free physical mode. The production line can be usedfor removing the oxide scale on the surface of the strip steel through means such as heating, cooling, scale breaking, grinding, washing, and passivating. The production line has the characteristics of being low in cost, simple in process, free of environmental pollution and the like.

Description

technical field [0001] The invention belongs to the technical field of iron and steel processing, and relates to an acid-free physical treatment strip scale production line. Background technique [0002] At present, chemical treatment is used to remove oxides on the surface of the original steel strip in industry, that is, the chemical reaction between strong acid and iron oxide is used to remove oxides. However, this pickling method is not only complicated in process, high in cost, and has certain potential safety hazards, but also brings great pollution to the environment when disposing of waste materials. Contents of the invention [0003] The object of the present invention is to solve the above problems, and provide an acid-free physical treatment strip scale production line, which has the characteristics of low cost, simple process, and no environmental pollution. [0004] The purpose of the present invention is achieved in this way: an acid-free physical treatment ...
