General Description of the Lifting Electromagnet
1. Applications:
* Applied to lifting and transporting magnet-conductive materials such as steels and irons in metallurgy, mine, machinery, communication and transportation industry and etc.
* Used as electromagnetic manipulator to hold magnet-conductive materials as steels and irons.
2. Main Features
* All-welded construction with moisture-proofing.
* Optimized designs by computer with reasonable structure, light dead-weight, strong attraction force and low energy consumption.
* The energizing coils are processed by special technology to improve the electrical property and mechanical property of the energizing coils. Heat-resistant grade of insulating material reaches Grade C with long service life.
* Duty cycle of normal type electromagnet increases from 50% in the past to 60%, which improves the efficiency of the electromagnet.
* Ultra-high temperature type electromagnet adopts unique method of heat-protection, the temperature of the attached materials is increased from 600°C in the past to 700°C, which expands application range of the electromagnet.
* Simple and convenient installation, operation and maintenance. |

3. Notes on Model Selection
* If temperature of the attached material is below 100 °C, please choose normal temperature type .If it is above 100°C, please choose high temperature type. If it is above 600°C, please choose ultra-high type.
* When power-on sustaining rate is above 60%, please choose high frequency type.
* When lifting and transporting materials are in water, please choose diving type(depth of diving = 100m).The technical data of diving type electromagnet is the same as that of normal temperature type, so it is not list in catalogue. If customers need diving type, please state clearly when ordering.
* Environment temperature: -40 ~ +40°C. High temperature type-55~80°C. Height above sea level is not more than 2,000m.
* Corollary equipment: when using single unit, choose rectifier controller and its necessary equipment according to consumed power(current);when using combination of several units, choose it according to the sum of the consumed power(current)of the combined units. |

For sheet, plate, block, round or angle, Kemeida has a magnet for any application. Let Kemeida's engineers evaluate the feasibility of applying our principle to your magnet application.
How Electromagnet Works?
Here we take scrap steel for example. An electromagnet can be used for moving scrap steel from one place to another. In a scrapyard, a crane has a large iron disc that is not a permanent magnet. The crane operator lowers the electromagnet into a pile of scrap steel and then switches on the electricity. This causes the steel disc to become a powerful magnet. Scrap steel is attracted to the disc. When the operator switches off the electricity, the scrap steel falls off the disc. In this way, large amounts of scrap steel can be moved easily from one place to another.
Rectifier Controllers
Electromagnets require direct current power for operation. Whether used in manual or automated handling of ferrous parts, they must release the work as readily as they attract and hold. Release is a function of the rectifier and not the magnet. These rectifiers incorporate a provision for reverse current that ensures positive release of even those alloy steels which are magnetically retentive. Variable power and remote control are available. Rectifiers and rectifier-controllers are designed to provide reliable D.C. power for industrial electromagnets.
About Inquiry
To help you get the best magnet for your application, we should have the following information:
1. What are the materials you want to attract?
2. What kind of steel and iron? For example: steel scraps, steel billet, ingot, plate, bar or ball.
3. What's the lifting capacity you expect?
4. What kind of working site does the magnet work?
5. Do you want the Cable Reel? If yes, tell me hoist height of the crane.
6. Do you want the electric controller? |
