Generally, our electromagnets are widely used for clients to steel scraps, billet, girder, slab, wire (coiled bar), bundled rebar, round steel pipe, heavy rail, steel plate, coiled steel, and other materials, etc.
What is electromagnets?
Lifting electromagnet usually be used with eletromagnet overhead cranes and electromagnet gantry crane and applied in steel factory, ship-building company, heavy machine manufacturing, steel storage, port and railway. It is to load ferro magnetic material instead of labour power to improve safety and efficiency.
It is the most ideal electromagnetic manipulator, freeing people from hazardous, abominable, and heavy labor. It also applied to some undesirable conditions, such as high temperatures, being submerged in water, being dusty, highly toxic, chilly, and wild. It is a necessary electronic device in metallurgy, transportation, and machine manufacturing.
The lifting electromagnet control is a complete control system. It has the ability to command the lifting electromagnet to increase its suction by using methods such as electricity excitation, cutting power degauss, or forced excitation. Furthermore, it adjusts the suction to achieve the unloading of the steel plate; even when the power is turned off, the lifting iron's suction can be maintained to prevent the steel object from falling off and injuring people or other equipment.
We also design and manufacture non-standard electromagnets based on the needs of our clients.
How to use electromagnet safely?
How to operate electromagnet safely? The following operation notices for your reference. If you have any need or problem about the electromagnets , please feel free to contact us.
Operating Notice of lifting electromagnet
- Check all welding joints on non-magnetic guard boards or other parts on a regular basis.
- Check the junction box and the cable, and repair or replace it as soon as possible.
- Examine the electromagnet insulation resistance and coil dc resistance on a regular basis.
- Examine the electrical control equipment.
- Examine the working current of an electromagnet in its thermal state. Stop it once over time and find how it happened.
- Maintain stable current and voltage, avoid unnecessary magnetic disturbance, ensure quick unloading, and avoid high and middle voltage impact current coils.
- Use the electromagnet in accordance with the operating rules; do not change the current arbitrarily.
- lIt must be used within the supposed working condition range.
How are the lifting electromagnet are produced?
First and foremost, we guarantee product quality of all our electromagnets. We adopt straightforward procedures, establishing and improving a multi-level quality guarantee system, and rigorous testing procedures. It is strictly banned to use unqualified materials and spare parts in production processes, and all of the electromagnets provided are of 100% qualified rate to achieve high lever of customer satisfactions.
Main production stages of lifting electromagnet
- Purchasing and sorting raw material and parts.
- Parts manufacture and quality inspection.
- Assembly and quality inspection.
- Insulation glue water
- Drying, cooling
- Finished product processing.
- Inspection before delivery.
Welding process of crane electromagnet
Lifting electromagnet welding includes shell structure welding, non-magnetic guard board and shell welding (including cast steel shell),which all adopt arc welding.
- Welding of electromagnet shell structure -Low carbon steel plate is used to weld the structure, with the features of high density , few leftover materials, and short production, making it suitable for simple, small batch, and short production products. However, its integrity and sturdiness are inferior to that of cast steel parts.
- The non-magnetic guard board and shell welding -The non-magnetic guard board is made of non-conduction alloy steel, whose material is 1Cr18Ni19Ti , manganese board is 20Mn23AL. It is dissimilar steel welding with shell, easy to craze. So choosing electrode is very important. Our factory use the Austenite stainless steel electrode with good plasticity and crack resistance. Andmore, the drawing should tell that the welding parts must be heated when in low room temperature in winter.
Preparation before electromagnet welding ：
- Preliminary working: the weldable joint is stressed. (For example, up cover board and boundary pole, up cover board and iron core) It must be finished by machine work with a minimum fineness of 6 grade. Straightness and flatness must be at least 9 grades. And the weld groove is created in accordance with the design drawing.
- Choose an electrode: T42 steel electrode is suitable for electromagnets with mild steel shells.
Lifting requirements for electromagnet welding
- Welding request: The welding on the shell must comply with GB986 standards. In accordance with GB3323 standards, lug welding is classified as H class. These requirements must be noted in the drawing and communicated to the welding demanding.
- Welding process requirements: the drawing should emphasize the importance of keeping the connection tight and avoiding being out of shape while working.
