BILSTEIN uses state-of-the-art, often fully automated annealing technology with high-convection hydrogen annealing. This ensures an even temperature distribution with only slight deviations from the coil volume. We guarantee optimum strip cleanliness alongside very tight mechanical and technical tolerances, zero oxidation, uniform technical values, bright, spotless surfaces, and zero oxidation along the edges. A variety of annealing programs enable us to provide a broad range of quality standards with a high degree of flexibility.
When it comes to heat treatment, we possess integrated, system-specific expertise. The annealing lines, which operate around the clock with batch sizes of 66–88 tons, are automatically controlled, monitored, and logged, ensuring a high degree of accuracy in meeting the desired mechanical and technical values and structures.
