Grid magnet
Round grids
Rectangle grids
Strong magnetic tubes fixed onto a stainless stell framework comes a grid magnet. When anything containing iron sunbstances passes through the framework, the iron substances will attach themselves onto the wall of the tubes. So your productions will be safe for consumption.
SS casing: ss316l, ss304l
Chou mag can supply you many kinds of magnetic separators. This kind of separators is called cleanflow magnets which is to remove tramp iron from heavy flows of materials which normally bridge or choke when processed through magnetic grid separators.
Size can be required as your requirements.
Casing: ss304l & ss316l
Chou Magnetics Co., Ltd is skilled at many kinds of magnetic devices. Our lifting magnet has strong magnetic path produced by supermagnets-NdFeB. On and off of the magnetic path is controlled by turning the manual handle. The lifters have the features of strong attraction, smaller volume, lighter weight, powerful lifting effort, easy and safe to install, long-period effort and without power supply. They are used to lift and transport the steel and iron for factories, docks, ware houses, transportation etc
Liquid magnet traps are designed for heavy duty, large volume liquid and semi-liquid line flow systems. It provides magnetic protection for liquid lines and processing equipment. They preserve product purity by removing small contaminants. Magnetic configuration ensures maximum exposure of contamination to the high intensity tubes without impeding liquid flow.
With its flange or quick release clamp top access design, the trap is easy to clean. Simply remove the top, lift out the magnet cage, wipe clean and reinstall.

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?
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.
