Tramp Metal Removal for the Steel Industry
At a Glance
Steel plants remove tramp metal (also called tramp iron) from raw material conveyors using a magnetic pulley, suspended magnet or magnetic drum separator, protecting blast furnaces, sinter plants and rolling mills from equipment damage. PML supplies magnetic separation equipment for iron ore, coke, sinter, pellet and scrap charge handling in the steel industry.
Steel plants remove tramp metal from raw material conveyors — iron ore, coke, sinter, pellets and scrap charge — with a magnetic pulley at the conveyor head, a suspended magnet ahead of it, or a magnetic drum separator for continuous bulk flow, protecting blast furnaces, sinter plants and rolling mills from equipment-damaging tramp iron. Below is which equipment fits which point in your process.
Why It Matters
- Blast furnace and sinter plant damage — tramp metal reaching a blast furnace charge or sinter feed can disrupt the process and damage equipment built for a precise material mix.
- Rolling mill damage — tramp metal in the charge can score or damage mill rolls and housings, an expensive repair on high-value equipment.
- Conveyor belt damage — sharp tramp metal punctures and tears belting on the high-throughput conveyors that move raw material through an integrated steel plant.
- Unplanned downtime — a steel plant's raw material handling runs continuously; equipment failure from tramp metal means costly, unscheduled stops.
Which Equipment Fits Your Line
Magnetic Pulley — replaces or supplements the standard head pulley on a raw material conveyor, continuously pulling tramp iron out at the discharge point with full-face coverage across the belt. The standard solution for iron ore, coke, sinter and pellet handling ahead of a blast furnace or sinter plant.
Suspended Magnet — mounted above the conveyor where a head-pulley retrofit isn't practical, or to intercept larger tramp metal before it reaches the pulley or downstream equipment.
Magnetic Drum Separator — a dedicated, self-cleaning unit for higher-volume or higher-contamination raw material lines feeding continuous processes.
Eddy Current Separator — where scrap charge material also carries non-ferrous metal, an eddy current separator sorts that out in the same line, alongside standard tramp-iron removal.
Tata Steel Limited
- Installation
- An 800mm diameter × 2,250mm effective-length high-intensity magnetic pulley, rated 4,500 ± 500 Gauss, in service on a raw material conveyor at Tata Steel's Kalinganagar plant.
- Why a Magnetic Pulley
- Installed as a direct head-pulley replacement, giving full-face tramp iron protection across the entire belt width without adding a separate unit or new controls to the line.
Frequently Asked Questions
How do I remove tramp metal while manufacturing steel?
Install a Magnetic Pulley at the conveyor head or discharge point on your raw material handling line, or a Suspended Magnet and Magnetic Drum Separator for higher-volume or harder-to-retrofit lines.
Where does tramp metal come from in a steel plant's raw material?
Iron ore, coke, sinter, pellets and scrap charge can all carry tramp metal picked up during mining, transport, handling or from worn equipment further up the line.
Is there a proven installation in a steel plant I can reference?
Yes — an 800mm diameter × 2,250mm effective-length high-intensity magnetic pulley (4,500 ± 500 Gauss) is in service at Tata Steel's Kalinganagar plant, Odisha.
Can this protect a blast furnace or sinter plant, not just a rolling mill?
Yes — a magnetic pulley or suspended magnet on the raw material conveyor feeding a blast furnace or sinter plant removes tramp metal before it enters the process, the same principle as protecting a rolling mill charge.
What if my scrap charge also has non-ferrous metal in it?
An Eddy Current Separator sorts non-ferrous metal out of a scrap stream in the same line as standard tramp-iron removal — ask our engineering team about combining both in one process.
