Points:
1. The standard cylindrical magnetic bar is 25mm(1 inch) in diameter, and the length can be machined according to customer requirements, up to 2500mm.Square or other magnetic rods of different shapes and sizes are also available.
2.Use 304 or 316L seamless stainless steel tube, the surface can be polished to meet the special requirements of food, pharmaceutical and other fields.
3. Standard operating temperature ≤80℃, under special requirements, the maximum operating temperature can reach 350℃.
4.Diversified design at both ends ---- tips, threaded holes, studs, etc.
5. Using ferrite permanent magnet and rare earth permanent magnet of different grades, magnetic rods with different surface magnets can be produced to meet the needs of customers. The maximum surface magnetism of MAGNETIC rods with D25mm can reach 13000GS.
Magnetic bar is a simple and practical magnetic filter with a wide range of applications. It is used to adsorb ferromagnetic particles around it to remove iron and protect subsequent equipment.You can follow the following steps to design and select a suitable magnetic bar:
Calculate magnetic field strength
The precise magnetic field strength is calculated by finite element method, but the complicated and tedious steps are daunting. It can be simply selected for the following applications and corresponding table magnetism:
|
Dry powder |
7000-8000 gauss |
|
paste |
9000-10000 gauss |
|
Nanoparticles, |
> 12000 Gauss |
Determine the size of the powerful magnetic bar
1. Diameter: The magnetic bar adopts standard series of stainless steel pipe, the outer diameter and the maximum surface magnetic field can be reached as shown in the table:
2.Length: Length customization.
3. Working temperature: ferrite magnet, Ndfeb magnet and high temperature resistant samarium cobalt magnet are available.
Mounting method of magnetic bar
In addition to the iron bar at both ends of the plug in various forms, commonly used are:
Threaded hole
Screw head
Flat head
Mounting method of magnetic bar

SS304 |
Widely used in most environments |
|
SS316/316L |
More corrosion resistant, used in the pharmaceutical and food industries |
The magnetic bar iron remover is composed of high density magnetic field magnetic circuit composed of strong magnet and magnetic guide sheet. It is sealed in stainless steel tube by argon arc welding. After strict polishing process, the surface is smooth without leakage, waterproof and antifouling.It can absorb ferromagnetic materials in mud and powder, and nano-sized particles can be absorbed when 12000 Gauss is above.
