New Generation Steel Strip Continuous Annealing

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

steel and aluminium coil coating&printing line

Aluminum coils or galvanized steel strip is painted and baked twice in coating lines and printed with some patterns to ensure high resistance and appealing appearance. the coil printing line is composed of uncoiler, sewing machine, accumulator, degreasing and washing unit, roller coating machine, printing pattern machine, furnace, shear, coiler etc.

Features of steel and aluminium coil printing line:
1. Utilize high precision rolling coater with excellent quality of coating layer.
2. A fine coating layer meets international standard.
3. It is suitable for coating with Acrylic, Polyester, Polyvinylidene Fluoride (PVDF).
4. Easy to operate and control, and provide the online operation training.
5. Designed to fit the area of customer's factory.
6. Coater consists of PU and Chromate coating rollers with advantages as:

Pu roller:
Available for full coat.
Matted surface effect.
Adapt to wooden,granite pattern effect.
Coating thickness can be thin & thick.
Minor impurities won’t cause surface defects easily.

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 launch of " JJRS-Sendzimir" depends on a number of technology patents innovated by ourselves.
