Abstract

The invention provides a strip steel surface acid-free descaling complete device which meets the strip steel surface descaling. A steel strip undergoes treatment through supporting devices such as two groups of multi-roll toothed descalers, a green fabric dust-free polishing machine and an automatic balance steel brushing machine, so that oxide scale on the surface of a steel plate is thoroughly eliminated, and the requirements of cold rolling of strip steel and strip steel surface galvanizing are met. The strip steel surface acid-free descaling complete device has the advantages of being free of acid consumption, noise and dust and eliminating the pollution to the human body, the environment, devices and rivers caused by acid pickling. The strip steel surface acid-free descaling complete device does not consume coal power for heating and high-pressure water and is low in cost, small in investment and occupied space and good in comprehensive benefit.

Description

technical field

[0001] The invention relates to the field of hot-rolled steel processing, in particular to a complete set of equipment for acid-free descaling on the surface of strip steel and a descaling method thereof. Background technique

[0002] Before cold rolling and galvanizing, the surface oxide scale (commonly known as "scale") must be completely removed. The traditional descaling methods are pickling descaling and abrasive high-pressure descaling.

[0003] 1. Disadvantages of pickling and descaling:

[0004] 1. The pickling environment is highly polluted, the acid mist is seriously harmful to the human body, and the surrounding environment and electromechanical equipment are severely corroded.

[0005] 2. High cost. The solution for pickling and descaling needs to be heated to 80 degrees, and the heating cost per ton is 60-80 yuan, or even higher.

[0006] 3. It occupies a large area. The length of the production line is 150 meters to 200 meters.

[0007] 4. ...
