Special Electro Lifting Magnets
Spacer Electro Magnet (CELM)
Designed for High-Temperature Materials
Handling high-temperature materials is one of the main challenges for lifting magnets, often leading to downtime and premature wear. The SGM CELM lifting magnet is specifically designed for applications involving slabs, blooms, and billets coming directly off casters.
- Heat Isolation Technology – The proprietary CELM design eliminates direct contact between the ferrous core of the magnet and the hot material, preventing heat transmission to the winding.
- Extended Duty Cycle & Lifespan – By minimizing heat absorption, the CELM magnet significantly increases operational longevity and reduces downtime, ensuring continuous and reliable performance in high-temperature environments.
- A Revolutionary Advancement – The SGM CELM lifting magnet represents a breakthrough in lifting magnet technology, setting new standards for durability and efficiency in high-temperature applications.
Lifting Magnets with No Side Magnetic Attraction
In certain applications, unwanted magnetic attraction to surrounding structures can disrupt operations. SGM’s proprietary magnet design drastically reduces side attraction, ensuring smooth handling in storage and processing environments.
- Optimized for Steel Service Centers – These magnets can enter racks without interference from steel columns or adjacent bundles/packs, preventing unintentional magnetic attraction.
- Ideal for Remote Operations – The reduced side attraction makes these magnets particularly suited for large storage facilities where precision handling is required.
SGM Mega Scrap Magnet
Optimized for Consteel® Technology
The SGM Mega Scrap Magnet is an advanced alternative to traditional circular scrap magnets, specifically designed for belt loading in Consteel® operations. Its innovative design improves the efficiency and uniformity of scrap handling, ensuring a steady, controlled flow of material onto the conveyor belt.
Benefits
One of the key advantages of the SGM Mega Scrap Magnet is its patented double magnetic circuit, which ensures a homogeneous distribution of scrap across the entire magnet surface. This eliminates the “mushroom effect” commonly seen in circular scrap magnets, where material tends to accumulate unevenly, leading to inefficiencies in loading.
By maintaining a consistent scrap feed, the Mega Scrap Magnet optimizes energy consumption in Consteel® processes, reducing fluctuations in material supply and enhancing furnace efficiency. The system prevents pile-ups and inconsistencies in scrap flow, allowing for precise material distribution on the conveyor belt and minimizing material loss.
To further refine loading control, the magnet features a tipping function, an electronic system that momentarily cuts voltage to the magnet, enabling the operator to regulate the drop of scrap onto the belt. This ensures even distribution, preventing excessive accumulation in specific areas.
Designed for intensive industrial use, the Mega Scrap Magnet incorporates an octagonal structure and anodized aluminum windings, which enhance heat dissipation. This prevents overheating, prolongs the operational lifespan of the magnet, and ensures continuous high performance even in demanding environments.
Additionally, the integrated over-excitation function accelerates magnetization and demagnetization times, increasing the overall efficiency of the handling process. This feature allows for faster operational cycles, reducing downtime and boosting productivity in scrap yard and steel mill applications.
By combining innovative design, energy efficiency, and enhanced operational control, the SGM Mega Scrap Magnet sets new standards in scrap handling technology, ensuring optimized performance and reliability in Consteel® processes.
CDMD Safety Device
Ensuring Stability in Lifting Dynamic Loads
In certain lifting applications, loads do not always behave as rigid, compact units. Multiple steel plates, eye-horizontal coils, or bundles of structural profiles can experience flexing, shifting, or partial separation when lifted by a magnet. This movement can generate additional dynamic forces, increasing the risk of instability and making handling more challenging.
To address this issue, SGM has developed the proprietary CDMD safety device, which is mounted directly on the magnet. This system monitors load behavior in real time, detecting any excessive flexing, shifting, or opening within the load. By continuously analyzing these movements, the CDMD ensures that they remain within safe operational limits, preventing uncontrolled load displacement and improving overall safety during lifting operations.
By integrating the CDMD safety device, SGM lifting magnets provide enhanced control and stability, ensuring safe and efficient handling even in complex lifting scenarios.
Magnet Windings
Made of Anodized Aluminum Strip
SGM lifting magnets utilize anodized aluminum strip windings, an advanced solution that enhances performance, efficiency, and durability. Anodization is a chemical oxidation process that forms an insulating coating directly bonded to the aluminum surface.
This innovation eliminates the need for traditional electrical insulator tape between the winding turns, allowing for:
- More compact winding coils – The freed-up space enables additional aluminum turns, resulting in a stronger magnetic field.
- Superior heat dissipation – The direct metal-to-metal contact significantly improves thermal efficiency, reducing overheating and enhancing magnet performance in continuous-duty applications.
- Extended magnet lifespan – The improved cooling capacity helps maintain stable performance over time, reducing wear and prolonging the operational lifetime of the magnet.
By incorporating anodized aluminum windings, SGM magnets set new standards in efficiency, reliability, and long-term durability in industrial lifting applications.
