Color coating lines for carbon steel

Flat products
Versatile, organically coated steel strip

What makes color coating lines such an attractive proposition is that they apply a high-quality coating to strip so it can go directly into processing end products. This eliminates costly manufacturing stages. Available to you from SMS group are color coating lines for various steel strip applications. These lines differ depending on the final use of the material. Yet you always get complete lines from a single source, all designed to accomplish several sophisticated processes. Naturally, the highlight is the compact coating process. We ensure the chemical strip pre-treatment, subsequent color coating, and drying oven are perfectly synchronized. That way, you achieve excellent quality at low resource and energy consumption.

Process sequence
First, the strips enter the line alternately from two payoff reels and are joined by a stitcher into endless strip. This collects in a vertical looper. Next up is a spray and brush degreasing unit that cleans the strip surface.

Then a chemcoater applies a conversion layer, followed by vertical drying. The strip is primed in a prime coater, then goes through the first horizontal hardening furnace. As it travels through finish coater 1 or 2 , it's coated with a top coat that hardens in the second horizontal furnace.

The next station is a vertical looper. Downstream of this is an inspection stand that checks the strip before it is cut and wound into coils.

Regenerative thermal oxidizer

Our regenerative thermal oxidizer system (RTO) burns the flue gases in the oven with a thermal efficiency of 98 percent. Depending on the solvent content in the exhaust air, the afterburning system and even the oven itself can be operated without additional energy input (autothermal mode).
