New Generation Steel Strip Continuous Annealing
Hot Dip Galvanizing (Aluminizing) Technology --- JJRS-Sendzimir
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".
The continuous high-speed hot rolled galvanizing lines include the following sections, assemblies, and machines:
Input section:
1. Coil rack
2. Loading carriage
3. Dual decoiler system- -Alternative operation of decoilers, coil weight 10 to 40 t
4. Two thickness gages - Designed for initial strip thickness control
5. Dual guillotine shears - for cutting the beaded edges of the strip in the alternatively used coils
Butt-welding machine - is equipped with straightener rollers and performs welding of strip ends of two coils; weld thickening no more than 10%, weld strength no less than 85% of the main strip characteristics
6. Looping pit
7. Disc shears - Designed for cutting the strip side edges; shearings are cut up by scrap cutter
8. Stretching machine
9. Stretching rollers
10. Multistorey storage loop (accumulator) - Automatically monitors the strip stock and has end trolley for constant stretching of the strip.
Strip electrochemical cleaning section
The strip is cleaned in baths with alkali solution; after that, it is washed and dried in a way similar to that described for the strip pickling line above.
Strip hydro-dynamic cleaning section
1. Guide rollers
2. Two vacuum housings
3. Dual rotary blowers
4. Dual high-pressure pumps
5. Two cyclone separators
6. Circulation water treatment system
