Process of magnet production: smelting

Smelting is the first process to produce sintered NdFeb strong magnet. The smelting furnace produces an alloy sling strip. The process requires the furnace temperature to reach 1300 degrees Celsius and lasts four hours to complete.After this process, the raw materials of the magnet are processed into alloy sheets by hot melting and cooling, and then the next process is hydrogen crushing.

The smelting section is carried out after the batching. This step is mainly responsible for casting the prepared material into plates or ingots, which are respectively done in large furnaces and small furnaces.Dongguan Jugo Magnet Factory to explain the casting smelting:

1. The instruments and tools and auxiliary materials needed in smelting are basically the same, such as gloves, masks, lighting tools, etc. Comparatively speaking, the ingot casting process is complicated, so it is necessary to pay attention to wearing the ingot during casting to avoid burns;

2. Secondly, carefully check the wire rope and other equipment when hoisting, and it needs to be carried out in no man's land;

3. Abnormal phenomena should be paid attention to when pouring, and can be continued only when there is no abnormal phenomenon;Fourth, mask should be worn to replace tunic to reduce the harm of dust to human body, prevent human body from polluting the casting piece, and prevent the casting piece from scratching human body.

The smelting section of ndFeb magnet plays a crucial role in the subsequent powder making, magnetic field orientation and sintering. Improper handling of such a link will bring irreversible impact on the overall performance of the magnetic material.
