Description

technical field [0001] The invention relates to the technical field of processing design of new nanocrystalline soft magnetic alloy materials, in particular to a melting device applied to nanocrystalline soft magnetic alloy materials. Background technique [0002] Soft magnetic materials are widely used in the field of magnetic materials due to their small coercive force and easy magnetization and demagnetization, such as computers, mobile phones, flat-panel display technology, etc., as well as various magnetic amplifiers, filter coils, variable frequency inductors, variable frequency transformers, inverters, etc. Transforming power supply, energy storage inductors and other devices. [0003] Iron-based amorphous alloy material is a new type of soft magnetic material, which controls the arrangement of liquid metal at the atomic level through rapid solidification, so that the atomic arrangement maintains the long-range disordered state of liquid metal. Due to the irregular a...

Problems solved by technology

[0009] The annular water tank type is a ring structure with a cavity welded by steel plates, which can continuously input cold water into the cavity of the sealing ring through the outside and discharge it synchronously to achieve the effect of cooling; although the annular water tank type is relatively tight Good (it can be attached to the inner wall of the electrode hole and the outer wall of the electrode), but because the inside of the sealing ring cavity is a whole cavity, it is difficult for cold water to form a good flow path and regular flow direction in the sealing ring cavity , so the cooling effect on the electrode is not good;

[0010] The serpentine tube type is formed by bending a seamless steel tube around the electrode periphery, which can form a spiral diversion path, and the cold water has a regular flow direction, so the cooling effect is better than that of the annular water tank type, but because it cannot completely fit the electrode hole The inner wall of the cover and the outer wall of the electrode, so the sealing is poor, and the electrode on the upper part of the cover cannot be well protected, so it is not currently used on a large scale

[0011] In addition, in order to ensure the cooling efficiency and reduce the difficulty of processing, the existing electrode sealing ring is generally processed into a thin-walled closed body, but the inner hole of the electrode sealing ring is easily burned and leaks after being subjected to high temperature and electric contact with the electrode. Water leakage will affect the steel quality

Therefore, the service life of the electrode sealing ring is short, and the furnace is often shut down for replacement; while the structure of the electrode sealing ring with a gap is almost a whole ring, it needs to be inserted into the electrode hole and inserted into the electrode for replacement, which is difficult to replace and greatly affects the furnace base. operating rate, but also increase the labor intensity of maintenance workers
