When C-hooks are in constant operation, the electricity required to keep motors running adds up quickly. This can lead to high energy bills in steel mills, especially if the equipment is used for long hours every day. The more frequently the C-hooks are used, the higher the energy costs can become, which makes them less efficient compared to alternatives that offer lower energy consumption.

Coil Lifting Magnets: Energy Efficiency

Coil lifting magnets, whether electromagnets or permanent magnets, operate with more focus on energy efficiency.

• Electromagnets: These require a power supply to generate the magnetic field needed to lift the coil. The energy consumption of electromagnets is relatively low while they are in operation, but they require energy only when activated.
• Permanent Magnets: These magnets are even more energy-efficient as they don’t require any power to maintain their magnetic field. The only energy needed is during activation or deactivation, when the field is turned on or off.

Power Requirements for Activation and Deactivation of Magnets

Electromagnets need a continuous power source to keep the magnetic field active. However, once the magnet is deactivated, it doesn’t draw energy, making it quite efficient during periods of idle time. Permanent magnets, on the other hand, don’t need any energy for their magnetic field to stay active, making them highly energy-efficient throughout the operation.

Comparison of Energy Efficiency with C-Hooks

• Electric C-Hooks: They consume constant electricity, especially if used for long periods. This leads to higher operational costs in the long term.
• Coil Lifting Magnets: In general, magnets consume less energy, particularly permanent magnets.
