Electromagnetic Overhead Cranes are core handling equipment for high-temperature and high-load environments such as steel metallurgy and port logistics. The performance stability of their core components, the electromagnets, directly determines the efficiency and safety of operations. However, in high-temperature environments, the electromagnets are prone to magnetic attenuation and insulation aging due to temperature increases, which may cause safety accidents or downtime losses in serious cases.
1. Challenges of High Temperature to Electromagnet Performance
In scenarios such as continuous casting workshops and high-temperature metal processing areas in steel plants, the ambient temperature can reach above 50°C. Electromagnets exposed to high-temperature environments for long periods face multiple challenges:
Magnetic Force Attenuation: High temperatures cause the resistance of the electromagnet coil to increase, leading to decreased current efficiency and a significant drop in magnetic adsorption force.
Material Thermal Expansion: Metal parts experience structural deformation due to thermal expansion and contraction, affecting the fit between the electromagnet and the material.
Insulation Aging: High temperatures accelerate the aging of the coil insulation layer, increasing the risk of short circuits and threatening the life of the equipment.
Heat Dissipation Problem: Traditional air cooling is inefficient in high-temperature environments, causing electromagnets to overheat and trigger protection shutdowns.
2. Jinghe Crane's Innovative Solution
In response to the issue of electromagnet performance degradation in high-temperature environments, Jinghe Crane has achieved technological breakthroughs in three dimensions: material science, intelligent control, and structural design. They have launched several highly adaptable electromagnetic overhead crane products:
1. Upgrade of High-Temperature Resistant Materials
Special Alloy Coil: Utilizes copper-aluminum alloy wire, reducing resistivity by 30% and minimizing heat generation.
Nano-Ceramic Insulation Coating: Increases temperature resistance up to 180°C, extending insulation life by more than twice.
Heat-Resistant Magnetic Pole Design: Employs composite magnetic materials (e.g., NdFeB + high-temperature adhesive) to ensure magnetic stability at high temperatures.
2. Efficient Active Heat Dissipation System
Dual-Circulation Liquid Cooling Technology: Embeds coolant pipes in the electromagnet, combined with external air cooling, increasing heat dissipation efficiency by 50%.
Intelligent Temperature Control Module: Monitors electromagnet status in real-time through temperature sensors and dynamically adjusts cooling power to prevent overheating shutdowns.
3. Adaptive Magnetic Force Compensation Algorithm
AI Dynamic Current Adjustment: Automatically optimizes current output based on ambient temperature and load weight to compensate for magnetic attenuation caused by high temperatures.
Power Failure Emergency Protection: Equipped with a supercapacitor + permanent magnet backup device, maintaining adsorption force for up to 5 minutes during sudden power failures to ensure material safety.
4. Modular Fast Maintenance Design
Electromagnet Quick Change Interface: Supports replacement of high-temperature damaged modules within 10 minutes, reducing downtime.
Remote Diagnosis System: Predicts equipment health status through an IoT platform to achieve "preventive maintenance."
3. Industry Application Cases of Jinghe Crane's Electromagnetic Overhead Crane
Take the continuous casting workshop of a large steel group in Russia as an example. The ambient temperature of the workshop remains above 60℃ for extended periods. Traditional electromagnetic overhead cranes experience a 40% drop in handling efficiency due to magnetic attenuation, with a high failure rate. Jinghe Crane customized a high-temperature special model for this scenario:
Magnetic Stability: Maintains a magnetic retention rate of ≥95% in a 60℃ environment.
Continuous Operation Capability: Extends daily operation time from 8 hours to 16 hours.
Energy Saving Effect: Reduces energy consumption by 25%, saving over 500,000 yuan in annual electricity costs.
Safety: Achieves a "zero power failure and shedding" record within 3 years.
