Magnetic rod
The magnetic bar is composed of an internal magnetic core and an external cladding, and the magnetic core is composed of a cylindrical magnet block and a magnetic conductive iron sheet. A good magnetic bar should achieve a uniform distribution of magnetic induction lines in space, and the distribution of magnetic induction points should fill the whole magnetic bar as far as possible. Because it is generally placed in the moving product transmission line, the surface of the magnetic bar should be smooth with low resistance, and it should not contain harmful substances to the environment, so as to avoid polluting materials and the environment.
The working environment of magnetic bar determines that it must have certain corrosion resistance, high temperature resistance, and some occasions need relatively strong magnetic induction intensity. Different magnetic induction intensity can be obtained by using different thicknesses of magnetic plates. The choice of different magnets can determine the magnetic induction strength and temperature resistance of the magnetic bar. Generally, if you want to achieve the surface magnetic induction strength of more than 12000 Gauss on the conventional 1 inch diameter magnetic bar, you need N40 type NdFeb magnetic steel. High temperature resistant magnetic bar in the temperature above 150 degrees generally choose samarium cobalt magnetic steel. However, large diameter magnetic rods do not choose samarium cobalt, after all, the price of samarium cobalt is very high, a magnetic rod with a diameter of 50*500 costs tens of thousands of yuan.
The magnetic induction intensity of the surface of the magnetic bar is proportional to the size of the smallest particle that can be absorbed. In the field of batteries, pharmaceuticals and other fields, small iron impurities can also cause a great impact, so the magnetic bar of about 12000 Gauss should be selected. Other areas can choose a lower.
In the process of using the magnetic bar in contact with the fluid, the internal magnetic energy will have a partial irreversible loss, the loss exceeds the initial strength of 30% or the surface of the iron sheet, stainless steel steel pipe wear and tear, then the need to replace the magnetic bar, and can not let the leakage of the magnet magnet continue to work, magnets are generally brittle, the surface is coated with some oil, the environmental pollution is relatively large. Domestic magnetic bar manufacturers generally can work for 1-2 years under heavy load and 7-8 years under light load.
