[0036] Working principle:
[0037] As Figures 1-4As shown, the device realizes effective delivery of ammonia gas and uniform nitriding operation through the partition design in the box 1 and the optimization of the transmission mechanism 12. The inside of the box 1 is divided into two functional areas by the middle partition plate 11, one for ammonia gas filling and the other for nitriding operation. The partition design allows continuous replenishment of ammonia gas, ensuring the continuity of the nitriding process and avoiding interruption due to insufficient ammonia gas. The partition plate 11 is provided with a plurality of transmission mechanisms 12, which are evenly distributed on one side of the partition plate 11 and used to connect the two cavities. The transmission mechanism 12 is mainly composed of a transmission pipe 121, one end of which is connected to a fan 125 through a fixed rod 124, and the other end is installed with a sealing block 123 through a fixed block 122.

The sealing block 123 is made of elastic rubber material, which can bend to open to transport ammonia gas when the fan 125 is working, and the sealing block 123 will reset to the inner wall of the transmission pipe 121 when the fan 125 stops, playing a sealing role, thereby avoiding uneven nitriding caused by excessive delivery of ammonia gas.

In order to realize uniform distribution of ammonia gas, the transmission mechanism 12 is arranged in longitudinal arrangement, and the ammonia gas is uniformly delivered to each area of the placement block 9 through the transmission mechanism 12, so as to uniformly nitride the surface of the silicon steel, avoiding local over-nitriding or insufficient nitriding to cause product quality problems. In addition, the box 1 is provided with a controller 8 on the outer wall, and the controller 8 is connected with a heating assembly 10 in the box 1. The heating assembly 10 is used to decompose ammonia gas and generate nitrogen gas to act on the surface of the silicon steel in the placement block 9, further improving the efficiency and uniformity of nitriding.
