The smelting section is carried out after the batching. This step is mainly to carry out the casting or ingot casting of the prepared materials, which are respectively completed by the large furnace and the small furnace.

 Smelting is the first process for producing sintered NdFeB Magnets. The smelting furnace produces alloy enamel strips. The process requires a furnace temperature of about 1300 degrees for four hours. After the process, the raw materials of the magnet are processed by hot melt and cooling into alloy flakes, and then the next process is performed, and hydrogen is broken.

Smelting of cast pieces:

The instrument tools and auxiliary materials required for smelting are basically the same, such as gloves, masks, lighting tools, etc. In comparison, the process of ingot casting is complicated, and it is necessary to pay attention to wear when casting the sheet to avoid burns;

Secondly, when lifting, it is necessary to carefully inspect the equipment such as wire ropes, and it is necessary to carry out in the no-man's land;

Third, you need to pay attention to abnormal phenomena when pouring, and only continue when there is no abnormality;

Fourth, the replacement of the tundish needs to wear a mask to reduce the harm of dust to the human body, prevent the human body from contaminating the cast piece, and prevent the cast piece from scratching the human body.

The smelting section of the magnet (ndfeb magnet) plays a crucial role in the subsequent milling, magnetic field orientation and sintering. Improper handling of such a link will have an irreversible effect on the overall performance of the magnetic material.
