Nickel-Molybdenum Rotary Kiln Oxygen Top Blown, Refining Process
The Nickel-Molybdenum Rotary Kiln Oxygen Top Blown process is a method of refining nickel-molybdenum alloy material. The main objective of the process is to remove impurities, thus improving the performance quality of the alloy material. This process is carried out in a rotary kiln, in which a mixture of air, molybdenum, and nickel, is heated in order to form a homogenized mixture.
The nickel-molybdenum alloy is placed into the rotary kiln, and heated to produce a uniformed and homogenized alloy material. Pressure is added by introducing oxygen from an external source, and this pressurized oxygen is then forced down through the top of the kiln, where it combines with the nickel-molybdenum alloy mix and moves along the length of the kiln.
The combination of the pressurized oxygen and the nickel-molybdenum alloy mix produces a turbulent, plasma-like material which is then heated to a temperature of between 800-1000°C (1472-1832°F). At this temperature, the impurities present in the alloy material are burned off. In addition, refractory material may also be added to the mixture, which further assists in the removal of impurities.
Once the impurities have been removed, the oxygen-enriched mixture is then heated to a temperature of between 1150-1300°C (2102-2372°F). At this temperature, the alloy material undergoes a transformation which can be described as a solid-state diffusion. This solid-state diffusion is responsible for the removal of any remaining impurities from the alloy material.
The nickel-molybdenum alloy material is then cooled, either rapidly or slowly, depending on the customer’s specifications. This cooling process helps to ensure that the alloy retains its physical properties. After cooling is complete, the alloy material is subjected to a series of quality control tests which are designed to ensure that the alloy meets the desired customer specifications.
The Nickel-Molybdenum Rotary Kiln Oxygen Top Blown process is an effective method used to refine nickel-molybdenum alloy material. This process helps to improve the performance quality of the alloy and helps to extend the life of the material. The process also helps to ensure that the alloy meets customer specifications, ensuring customer satisfaction.
