Abstract

The invention relates to the field of metallurgical pressure machining and coating, and provides a steel coating device and a production method of the steel coating device. Production of hot-rolled acid-pickling-free steel and coating steel of other varieties such as galvanized steel is achieved. The steel coating device comprises a reduction cooling device, a coating device and an after-coating cooling device. The hot-rolled acid-pickling-free steel with glass films can be produced through the coating device arranged on an outlet of a hot rolling finishing mill. The steel coating device has the advantages that technical feasibility is high, investment is low, and the effect is remarkable; the requirements of various industries are met; coating materials are cheap, easy to obtain and high in renewable utilization value; energy conservation and emission reduction of multiple industries can be promoted, and meanwhile sound development of downstream industries is driven; online and simultaneous production of the acid-pickling-free steel and the coating steel can be achieved on one hot rolling production line.

Description

technical field

[0001] The invention belongs to the field of metallurgical pressure processing and coating, and in particular relates to a coating steel equipment and a production method thereof. Background technique

[0002] Existing hot-rolled steel is carried out at high temperature, which inevitably causes oxidation of the steel, so the subsequent processing has to remove the oxides caused by hot rolling through mechanical and pickling methods, and a large amount of waste acid is produced in the process Emissions have caused very serious pollution to the environment. At present, there is no effective alternative to pickling at home and abroad.

[0003] The existing process of on-line coating steel is that after the hot-rolled steel undergoes subsequent pickling and deep processing, it is heated and annealed again on the coating line, and then immersed in the coating tank for coating. This process not only causes environmental pollution, but also consumes energy, especial...
