In the metallurgical industry, coking, iron-making, steel-making, and rolling operations will produce high temperatures. In the machinery manufacturing industry, casting, forging, and heat treatment operations will also produce high temperatures, and the boilers in thermal power plants and on ships also belong to scenarios that produce high temperatures. The common feature of these scenarios is that it involves high-temperature processing or direct contact with high-temperature materials, so the workpiece or working environment will reach a higher temperature. In these scenarios, how to choose the magnetic gripper to\u00a0transport the workpieces processed at high temperatures is a problem that bothers everyone.<\/p>\n

Mechanical gripper and electric magnetic gripper <\/strong><\/h3>\n

Some people choose mechanical gripper, but through attempts, it is found that mechanical gripper\u00a0is prone to wear and deformation. It shortens the service life of the lifting gear and requires timely maintenance or replacement. There are significant safety risks. The lifting efficiency is also very low and it is difficult to meet the capacity requirements. The suction force of the electromagnet is directly related to its magnetic flux density, and the magnetic flux density of ferromagnetic materials will decrease with the increase in temperature. This is the principle of high-temperature demagnetization. When the temperature rises to a certain extent, the magnetic conducting ability of ferromagnetic materials will significantly decrease, resulting in hardly being attracted. Specifically, when the temperature approaches 730 \u00b0C, the ferromagnetic material will lose most of its magnetic conducting ability and can hardly be attracted. In addition, in a high-temperature environment, the suction force of the electromagnet will also cause the temperature of the electromagnet to rise due to the heat transfer of the steel, further resulting in a decrease in the suction force. Therefore, generally, objects above 200 \u00b0C are not allowed to be lifted.<\/p>\n

Electro permanent magnetic gripper<\/a>\"magnetic<\/strong><\/h3>\n

So, in this case, the electro\u00a0permanent magnetic gripper\u00a0will be a better choice for you. Because the electro\u00a0permanent magnet has undergone strict control in design and selection, and is custom-designed according to the on-site working conditions. It can consider many aspects such as increasing the temperature resistance level of its own materials and water cooling design. In this way, it ensures that the magnetic force loss at high temperatures is not significant. For example, the application of electro\u00a0permanent magnetic gripper\u00a0can also be extended to the aerospace, high-speed rail, and energy fields, etc. These fields usually require working in a high-temperature environment, and the stability and reliability of electropermanent magnets have been widely recognized.<\/p>\n

In particular, when dealing with high-temperature workpieces, the suction force of the electropermanent magnet will not significantly decrease due to the temperature of the workpiece, which is very important for many industrial applications. For example, in the heat treatment process, the workpiece has a certain temperature after being heated, but the electropermanent magnet can still effectively adsorb these workpieces, ensuring the smooth progress of the process.<\/p>\n

Conclusion<\/strong><\/h3>\n

In addition, by achieving the heat insulation effect between the high-temperature workpiece and the electro permanent magnet, the heat transfer to the body of the electro\u00a0permanent magnetic gripper\u00a0is effectively avoided, thereby greatly reducing the temperature rise of the body of the electro\u00a0permanent magnet, ensuring the suction force in a high-temperature environment. In summary, due to its unique performance and design, the electro\u00a0permanent magnetic gripper\u00a0can effectively adsorb the workpiece in a high-temperature environment and is an ideal choice in high-temperature industrial applications.<\/p>\n","protected":false},"excerpt":{"rendered":"
