[0002] Steel belt reduction furnaces are generally used in the reduction process of steel powder or other alloy powder preparation due to their good temperature uniformity and uniform distribution. In order to prevent the reduced iron powder and other metallurgical powders from being oxidized again, traditional steel belt reduction furnaces need to increase the cooling stroke, thereby increasing the overall length of the reduction furnace.

[0003] After the steel belt transfers the material into the tank, some dust of the material will still adhere to the steel belt and accompany the transmission of the steel belt, or fall into the reduction furnace, or undergo redox reaction with the next batch of metal powder again, thereby affecting the overall quality of metal powder redox and increasing the doping amount of the finished product after the later metal powder redox reaction, which is very inconvenient.
