Electromagnet
Kemeida Magnet currently operates in the largest of production lines to the smallest job shops and provides the same advantages of safety, high performance, and low operating cost for each user. 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.

Electromagnetic stirrer (EMS)
In principle, electromagnetic stirrer (ems) can be regarded as a rotary motor stator and liquid steel as rotator. Ems is placed lower in the mould to make the liquid metal rotate in the mold. The magnetic field penetrates the copper mould tube, stainless steel baffle tube, and any solidified shell and gives rise to induced currents in the melt. These interact with the traveling magnetic field and create a torque on and by that a movement of the molten steel. General speaking, ems can be usually placed in one of three locations (refer to drawing below):
Ems locaction
1. Mould electromagnetic stirrer (mems): ems is mounted outside copper tube.
2. Strand electromagnetic stirrer (sems): ems is mounted outside billet.
3. Final electromagnetic stirrer (fems): ems is mounted outside billet.
We seldom use the second mode now, but usually use the first or the third one, or use the two sorts in the same time.The metallurgical effects differ from different locations.
