Nickel-Molybdenum Rotary Furnace Blowing Introduction
Rotary furnaces are widely used in the ferrous and non-ferrous industry for melting and heat treatment of metals and alloys. With the use of rotary furnace blowing, it is possible to improve and increase the production capacity of the furnace. The nickel-molybdenum rotary furnace blowing process consists of three main stages: drying of the furnace, reduction of the furnace temperature and the blowing of the nickel-molybdenum powder into the furnace.
The first stage of the process is drying the furnace. The rotary bell design of the furnace is used to allow air to flow through the furnace, drying the lining and other components of the furnace. The drying of the furnace removes moisture which can have an impact on the overall efficiency of the furnace.
The second stage of the process is the reduction of the furnace temperature. The reduction of the temperature within the furnace helps to improve the flow of nickel-molybdenum powder within the furnace, with each port having a different purpose. The ports close when the furnace reaches its desired temperature, reducing the heat lost and preventing over-temperature conditions.
The third stage of the process is the actual blowing of the nickel-molybdenum powder into the furnace. Depending on the size and volume of the furnace, the amount of powder required will vary. A more powerful air compressor may be needed for larger volumes of powder. The air pressure and air volume for the blowing must be carefully regulated. The powder must be slowly introduced into the furnace so that it does not cool the furnace too quickly or cause turbulence within the atmosphere. If too much powder is introduced into the furnace, it can plug or overfill the furnace and cause poor circulation of the furnace gases.
Once the nickel-molybdenum powder has been blown into the furnace, the rotary bell is then sealed, while maintaining the reduced temperature within the furnace. The furnace is now ready for the production of its first material. The furnace continues to be heated until the desired temperature has been reached, allowing the nickel-molybdenum content to increase, at which point the production is ready to begin.
Nickel-molybdenum rotary furnace blowing is a process which can increase the production capacity of the furnace and improve the melting and heat treatment of metals and alloys. The careful regulation of the air pressure, air volume, and introduction of the nickel-molybdenum powder into the furnace are essential elements of the process, in order to ensure the desired results.
