Frequently Asked Questions:
How does this annealing process improve formability? By refining the grain structure and eliminating residual stress, the material becomes more malleable and less prone to cracking or wrinkling during bending, stretching, or deep drawing operations.
Is the system compatible with existing rolling mill setups? Yes—it can be retrofitted into most continuous pickling and annealing lines with minimal downtime and maximum return on investment.
What makes this different from traditional batch annealing? Unlike batch methods, our continuous approach offers consistent output, lower energy use per ton, and better control over metallurgical outcomes—ideal for high-throughput industries like auto manufacturing and construction materials.
Can the system handle varying thicknesses and grades of steel? Absolutely—the modular design supports a wide range of coil weights, widths, and alloy types, including low-carbon, dual-phase, and bake-hardening steels.
