Applications of Metal Detectors in the Steel Industry
Overview In the steel industry, the presence of tramp metal (unwanted metal pieces) and impurities is a constant concern. These metallic contaminants not only reduce the quality of the final product but also cause severe damage to machinery, leading to significant financial losses. An Industrial Metal Detector is a device installed (typically as an aperture or sensor coil) over the conveyor belt to prevent the passage of these hazardous metals.
Why are Metal Detectors Essential in the Steel Industry?
If metal impurities enter the production line and reach the machinery, they cause substantial damage to Crushing Systems and Material Handling Equipment. Installing a metal detector on the conveyor belt effectively prevents this issue. The dimensions of detectable metals vary depending on the machinery specifications and can be fully adjusted based on operational needs.
Difference Between Steel Industry Metal Detectors and Magnets
Magnets are only effective for attracting and separating magnetic metals and cannot remove non-magnetic metals such as Manganese steel or Aluminum.
A critical challenge in steel plants and Iron Concentrate Lines is that the raw material itself is often magnetic (e.g., Magnetite). Therefore, separating metal debris from the moving ore requires specialized metal detectors with high discrimination power. Our detectors utilize modern technology to distinguish and detect various impurities—both magnetic and non-magnetic—even when the product itself is conductive or magnetic.
Sources of Metal Impurities in Steel Production
Metal impurities can enter production lines from various sources and cause disruptions:
Metal pieces mixed within the raw materials.
Metal parts introduced during the production process (e.g., broken machinery teeth, bolts, or tools).
