Push Pull Pickling lines
CMI’s Push Pull Pickling lines are ensuring excellent operational flexibility in the face of frequently changing strip dimensions and steel grades, and also non-weldable material. Their specific design makes such lines the only practical way of descaling heavy gauge coiled product.
Semi-Continuous- and Continuous Pickling Lines
Semi-Continuous- and Continuous Pickling Lines are used for high capacity production with continuous operation by stitching or welding. In continuous pickling, the line runs at constant speed, while in the Semi-Continuous Line the speed of the strip is reduced during changeover or coil joining, due to the lower capacity of the strip accumulators (loopers).
Design features of CMI Industry’s continuous pickling lines to optimize pickling time, avoid over-pickling, increase production throughput and reduced line length:
- High turbulence pickling tank technology
- Spray pickling modules
- Pickling Process Management (PPM) system
- Fully automated acid control management system
In stainless steel pickling applications, CMI Industry’s Neolyte Purification Systems reduces harmful chromium (+6) to non-toxic chromium (+3) and regenerates the electrolyte, thus reducing operating costs and the environmental impact of such lines.
Fumes loaded with Nox produced during stainless steel pickling, are most efficiently treated in CMI’s latest generation of Selective Catalytic Reactors (SCR-Technology).
Pickling line designs
