Product Description

 

What is the magnetic bar?

 The magnetic bars are named because they are made of strong neodymium magnets or SmCo magnets. The ferrite magnet is in the stainless-steel tube by complete or incomplete welding. Due to the appearance of stainless-steel rods or polished rods, many customers also call them magnetic rods, magnetic rods, magnetic filter rods, or magnetic rods.

They are the most effective permanent magnet devices for capturing and removing ferrous metals from various materials in different fields. According to different conditions, they can be assembled with other stainless-steel parts into a grate magnet, magnetic drawer, or magnetic trap. There are square and round solenoid tubes.

Magnetic Bar Specification

The magnetic rod is made of high-quality stainless-steel tube and rare earth alloy NdFeB and is made by a special production method. It can be combined on a holder to form a magnetic filter. When the iron-containing substance passes, it is attracted by the force bar, and the iron-containing substance is firmly adsorbed on the pipe wall of the magnetic bar to ensure the integrity of the equipment and the safety of the product.

Easy clean Magnetic bar

Easy Clean Shell

The cleaning shell specially used for magnetic strips, by inserting and pulling out the strip magnets from the box, the magnetic material attached to the bar can be removed.

The easy-to-clean magnetic bar independently developed by great magetch is widely used in the food, plastic, and pharmaceutical industries. With a screw head plug, it can prevent the magnetic rod from sliding out and keep the inside of the magnetic rod clean. Different screw plugs can be used to take out the magnetic rod after use so that impurities can be removed.

 

 

How does the magnetic filter tube work? 

The magnetic filter rod/filter rod/tube is made of 304 or 316 stainless steel tube, pole plate, end plug, and permanent magnet. The higher the surface Gaussian of the tube, the higher the price. Since permanent magnets are the most expensive parts, we will tell you how unethical companies can reduce the cost of manufacturing electromagnetic tubes with high surface Gauss.

Why choose us?

For the long-term use of a magnetic bar, at Greatmagtech, we use the best raw materials to make products. This makes the customer repurchase rate as high as 80%.

Demagnetization rate of magnetic bar

 

The price of magnetic bars on the market is very different. The magnetic bars with different prices are mainly due to the different demagnetization rates of the magnetic bars. Good magnetic bars have better permanent magnetism, while poor ones have very fast demagnetization. The main factors leading to the demagnetization of the magnetic rod are:

1) High temperature (exceeding the temperature resistance grade of the magnet material). Usually, it is lower than 80 degrees, and the influence on the magnet bar is limited. If it exceeds 80 degrees, you need to choose the corresponding high-temperature resistant magnet.

2) The magnet material itself. The magnet itself contains too many impurities, the weaker the magnetic retention ability. Usually choose to choose a material with a high coercivity (such as Alnico, etc.) in order to preserve the magnetism as much as possible and not make it disappear.

3) Strong external magnetic field. Generally, if the external magnetic field is stronger than the magnetic rod itself, it will easily lead to the loss of magnetism.

4) Impact. Frequent high-frequency impacts will affect demagnetization. Therefore, avoid rough installation and disassembly, and avoid installation at the place of vibration source.

5) Humidity. It means that the magnet itself will affect the magnetic force in a humid environment. The outside of the magnetic bar is usually covered with stainless steel, so it will not be affected by washing with water.

Note: The demagnetization of the magnetic rod is not directly related to the number of times the magnetic substance is adsorbed. In the process of the magnetic rod used by many Chinese companies, the demagnetization will occur quickly (more than 30% demagnetization in a few months to a year). It is believed to be caused by too much foreign matter adsorption. In fact, there is no direct relationship between the two. The demagnetization is mainly caused by the material of the magnet itself and its processing process. The demagnetization rate of Greatmagtech's magnet is about 1% five years, and it is no problem to use a magnet for more than ten or twenty years.

 

Strength check frequency of the magnetic bar

 The strength check of the magnetic bar is normally to use a Gauss meter to check the strength of the magnetic bar and keep the corresponding records. In the normal use environment of the magnetic bar, the weakening of the magnetism is relatively slow; there is no clear and specific requirement for the inspection frequency of the magnetic bar. The usual inspection frequency in the industry is 1 month to 3 months. If the environment used is harsh (such as high temperature, vibration, etc.), it is recommended to increase the frequency of inspection.
