Description

The new generation of continuous annealing hot dip galvanizing (aluminum) zinc plating technology for strip steel - (Ruisen Method)


The R&D team of Beijing Jingjie Ruisi Technology Development Co., LTD., through in-depth research and analysis, has integrated the advantages of the traditional process technology "Improved Senzimir Method", and incorporated its self-developed regenerative combustion technology and efficient waste heat reuse technology. At the same time, it has optimized the optimal thermal energy utilization technology and launched a new generation of continuous annealing hot dip galvanizing process control technology for steel strips. It has the technical advantages of high output and low energy consumption. As it combines the advantages of the Senjimir method with the patented technology of Jingjie Ruisi, it is named "Ruisen Method".


The research and development tenet of "Ruisen Method"

The true regenerative non-oxidation heating, highly efficient heat energy distribution process, and the "extreme recovery" of waste heat are energy-saving and environmentally friendly with no end


The two core features of the "Ruisen Method" are that compared with traditional processes, 

the "Ruisen Method" can significantly increase production capacity, which is attributed to:


◆High-temperature open flame one-time heating process: In the heating furnace, the strip steel can be directly heated from the 20℃ room temperature at the time of entering the furnace to the temperature zone where the strip steel can undergo recrystallization in a non-oxidizing atmosphere.


Zero insulation energy-saving concept: Under the premise of ensuring the annealing and reduction effects, carry out reasonable heat energy distribution. Try to heat the steel strip in the open flame heating section with high heat exchange efficiency to improve the utilization rate of heat energy, thereby increasing production capacity as much as possible and reducing energy consumption.

 

The technical patent of "Ruisen Method"


The launch of the "Ruisen Method" relies on a number of independently developed technological patents of ours:

The Seven Innovations of "Ruisen Method"  "Ruisen Method" is an all-round and comprehensive application of thermal energy new technology integration:


◆ Each section and internal structure of the annealing furnace: It is more conducive to the circulation of atmosphere within the furnace section and reduces the mutual interference of atmosphere in different sections.

◆ New type of regenerative burner: It enables higher preheating temperature of air, better pre-mixing effect of air and gas, higher combustion efficiency and more complete combustion.

◆ High-temperature flame directional heating technology: It enables higher heating efficiency and more uniform heating of the steel strip.

◆ Precise control of the air-fuel ratio and thermal power of the burner: It enables the temperature and atmosphere in the furnace to be precisely controlled in a zoned and local area, reducing (avoiding) the oxidation of the steel strip and achieving the oxidization-free heating annealing process of the steel strip.

◆ Energy-saving combustion secondary heat exchange technology of radiant tubes: By applying the concept of constant pressure source control, the radiant tubes are kept in the optimal working state for heating conditions.

◆ Automatic furnace temperature control function: After the parameters and states of the burner are set, all are controlled by the software. The operator does not need to operate the valve, avoiding operational errors that may affect product quality and energy consumption.

◆ Human-machine interaction dialogue mode: The screen interface is more friendly, parameter display is more intuitive, adjustment is more convenient, with powerful internal computing and prompt functions, which can avoid human errors and fully demonstrate the advantages of modern automatic control process technology.
