Guide to selecting lifting electromagnets

2025-03-21

The choice of lifting electromagnets is crucial to ensure operational efficiency and safety. The following is a detailed selection guide based on different application scenarios and needs. Basic selection principles· Material types and characteristics: First, consider the type of material to be lifted (such as steel, steel, billet, etc.) and its physical characteristics (such as size, weight, temperature). · Working environment: Considering the temperature, humidity and whether there are corrosive substances in the working environment, these factors will affect the selection and service life of the electromagnet. Different series of lifting electromagnets and their applications are specially designed series MW22, MW42, MW92 series: specially designed for suction and lifting initial rolled steel billets, profiles, and square billets. · MW03 series: suitable for suction and suspension thick plates, especially slabs. · MW73 series: mainly used for handling and flipping of slabs. · MW84, MW04 series: suitable for handling 6-32mm thick steel plates, among which the MW84 series can operate in single or multiple pieces, while the MW04 series can only operate in single pieces. Special purpose series·MW15-□54L,MW22-□54L series: used for suction and hanging bundling wire. · MW16, MW26, MW36 series: suitable for suction hanging steel belt coils. · MW12 series: used for suction and hoisting and strapping rebar, double-layer square billet. Precautions for selection Environmental factors·Ambient temperature: When the working environment is higher than 60℃ and the workpiece being hoisted is higher than 80℃, please choose a high-temperature resistant electromagnet. Electric permanent magnets cannot be used to lift materials with temperatures exceeding 450℃. · Loose materials or large suction work conditions: Please choose a strong magnetic permanent magnet. · Power supply conditions: If the power supply is inconvenient (such as in the wild environment), please choose a rechargeable lifting permanent magnet. · Toxic and radiant environment: Remote control operation can be used to improve safety. Use and maintenance· Continuous operation time: If the continuous operation time is too long, a backup method should be used, that is, more than two units should be operated alternately to avoid problems such as decreasing magnetic force and reduced operating efficiency. · Material temperature: When the temperature of the suction material is lower than 100℃, choose the normal temperature type; when it exceeds 100℃, choose the high temperature type; when it exceeds 600℃, choose the ultra-high temperature type. · Power-on sustain rate: When the power-on sustain rate exceeds 50%, please choose the high-frequency type. · Water suction hoist: When sucking materials in water, please choose a submersible type, the parameters are the same as the room temperature type. Equipment supporting· Single unit and multiple units are used: When a single unit is used, select rectification control equipment and auxiliary equipment according to the power consumption (current); when multiple units are used, select according to the sum of the power consumption (current) of the number of units used. Special design·Diver lifting electromagnet: suitable for water suction materials, diving depth shall not exceed 100 meters, and the parameters shall be the same as normal temperature type. · Ultra-high temperature lifting electromagnet: The temperature of the absorbed object is increased to 700℃, which has expanded the scope of application, and the heat resistance level of the insulating material can reach C.
