New Generation Steel Strip Continuous Annealing

Hot Dip Galvanizing (Aluminizing) Technology --- JJRS-Sendzimir

The special design features of this system deliver the following advantages:
Lowest dewpoints due to excellent furnace sealing concept and up to 100 % hydrogen process atmosphere to avoid surface oxidation, particularly for the highest-quality grades of electrical steel (> 2.5 % Si) at annealing temperatures > 1000 °C
Homogeneous slow cooling over the width of the strip in the cooling zone, for optimum flatness → good punching and laser cutting properties in the electrical steel strip

Material temperatures up to > 1100 °C feasible, especially with highly-efficient power plant grades such as M230-50A (> 3 % Si)
Strip as thin as 0.18 mm can be produced for high-frequency applications
Resource-saving and tailor-made furnace design to minimize wear part, utility and investment costs
The very latest burner/radiant tube technology and rapid heating-up systems for high heating gradients to achieve efficient decarburization and improved texture (crystalline orientation)
Process simulation before heat treatment makes it possible to identify suitable annealing programs to achieve the specified magnetic and mechanical properties
Hydrogen regeneration units, which provide hydrogen savings of up to 50 %, are available

Consolidating the advantages of the traditional technology " Improved Sendzimir" and "United States Steel Corp", and integrating the independently researched and developed regenerative nozzle and waste heat efficient recycling technology, the technology R&D team of Beijing JJRS Technology Development Co.,Ltd, launched a new generation of steel strip continuous annealing hot dip galvanizing process contrl technology based its latest self-designed process control technology by in-depth study and analysis, which is named as " JJRS-Sendzimir".
