An automatic annealing device for ammonia decomposition gas of soft magnetic alloy powder

Abstract

The invention discloses an automatic annealing device for ammonia decomposition gas of soft magnetic alloy powder, which is used in the technical field of soft magnetic alloy powder annealing, comprising an annealing furnace and an annealing furnace transmission mechanism, the annealing furnace has a furnace, and the front part of the furnace is equipped with The feeding furnace cover, the front end of the feeding furnace cover forms the material inlet, the rear part of the furnace is equipped with the discharging furnace cover, and the rear end of the discharging furnace cover forms the discharging port, and the feeding port and the discharging port are both lower than the furnace , the transmission mechanism of the annealing furnace can drive the charging tray equipped with soft magnetic alloy powder to enter the furnace through the inlet, and then exit the furnace through the outlet. In order to improve the quality of the powder, the present invention sets the inlet and outlet lower than the furnace, so that it is difficult for the outside air to enter the furnace, which is beneficial to improve the purity of the furnace atmosphere, so that the produced soft magnetic alloy powder products are both It can achieve good consistency, stability and magnetic performance, meet the market's demand for performance, and can greatly reduce production costs such as energy consumption, gas consumption, and labor costs, and enhance market competitiveness.

Description

technical field [0001] The invention is used in the technical field of soft magnetic alloy powder annealing, and in particular relates to an automatic annealing device for ammonia decomposition gas of soft magnetic alloy powder. Background technique [0002] In recent years, due to high-tech fields such as electronic information technology, solar technology, power transmission and transformation technology, and charging piles, not only the demand for soft magnetic alloy powders such as Fe-Si and Fe-Si-Al is increasing, but also with the With the development of components made of soft magnetic alloy powder in the direction of miniaturization and miniaturization, the requirements for the consistency, stability and magnetic properties of alloy powder are also getting higher and higher. Therefore, soft magnetic alloy powder in various places Body manufacturers not only strive to do a good job in smelting and powder making processes, but also try their best to tap the potential o...
