Push-Pull Coil-to-Coil Pickle Line | American Steel Products, Toledo, USA

American Steel Products's Push-Pull Coil-to-Coil Pickle Line cleans flat rolled steel strip by removing oxides and scale from the surface with acid. It is part of the finishing process for flat rolled steel and is offered new (built to order) or used.

In a push-pull line each coil is threaded through the process separately. There is no entry welder and no strip storage area, so the line handles individual coils rather than a continuous strip. The pickling tanks are generally shorter than those of a continuous line, because pickling speed is usually slower.

Key Features

• Push-pull layout: coils are threaded through the line one at a time
• No entry welder or strip storage area
• Pickling tanks generally shorter than on a continuous line
• Pickle liquor usually held at 180 °F or higher by external heat exchangers
• Fresh-water rinse section after pickling to remove acid residue
• Optional rust preventative oil or lubricant coating on both sides of the strip

Frequently Asked Questions

• What does a push-pull pickle line do? It removes oxides and scale from the surface of flat rolled steel strip by dissolving them in acid, then rinses the strip with fresh water.
• What is the difference from a continuous pickle line? A push-pull line has no entry welder or strip storage, so each coil is threaded separately, and its tanks are generally shorter because line speed is slower.
• Which acids are used? HCl is generally used for carbon steel, and hydrofluoric or nitric acids for stainless steel.
• What should I send for a quotation? Send the steel grade (carbon or stainless), coil width, thickness and weight, the output you need, whether you want oiling after pickling, and whether you want a new or used line.
