Electromagnetic iron remover to use for a long time, of course, to master the iron removal process should pay attention to:
1. According to the influence characteristics of ferromagnetic substances on ceramic products, analyze and determine the source and severity of ferromagnetic impurities in products, and then take appropriate treatment measures to stop the source.
2, in addition to the position of electromagnetic iron arrangement, should follow the following principles;
(1) Iron removal should be carried out in the screened raw materials to avoid large particles and other impurities into the iron removal tank (frame), which will hinder the normal performance of the iron removal device.
(2) Iron removal should be as far as possible at a low temperature in order to extend the service life of the magnetic bar.
(3) According to the type of ferromagnetic material, select the appropriate magnetic field intensity of the iron remoter: in addition to strong magnetic impurities to use a weak magnetic field to reduce the purchase and use cost; In addition to weak magnetic impurity must use strong magnetic field, purchase and use cost are higher. In the same production line, strong magnetic impurities should be removed first and then weak magnetic impurities should be removed.
3. The height of the slurry section of the permanent magnet slurry tank cut-off iron remover should be appropriate, and the ferromagnetic impurities on the upper surface should be basically guaranteed to be within the scope of the magnetic force.
4. Cleaning the magnetic bar is the key to ensure the effect of iron removal. If the interval is too long and the sealing layer around the magnetic bar is too thick, the peripheral ferromagnetic impurities will be far away from the effective range of the magnetic field, and the suction is not enough, the effect is not good, especially the high gradient magnetic field. The interval time period of cleaning should be determined by the amount of iron in the slurry (powder) combined with empirical data.
5, because the price of high and low temperature magnetic bar is different, the high temperature area and low temperature section of the iron eliminator can be distinguished, the use of different temperature levels of magnetic bar, in order to achieve the purpose of economic use.
6. The oxidation (rust) of the magnetic bar (core) will lead to the weakening of the magnetic field, which is because the oxidation will reduce the content of the original magnetic source in the magnet. So when the iron eliminator is stopped, it is necessary to clean the magnetic source carrier in the net, one is to prevent oxidation, the other is to prevent dry solid blocking. In addition, in addition to the purchase of iron magnetic bar, be sure to check whether the two ends of the seal is intact, no leakage, in order to prevent the use of magnetic core contact slurry to make the oxidation or corrosion and demagnetization.
7, knocking and vibration will change part of the magnetic moment direction of magnetic raw materials, and make the magnetic field weakened. Therefore, the operator must be very careful, but also to prevent the two magnetic rod suction clamping finger and accident.
