The production process of 90WMoNiFe alloy mainly includes several key steps: raw material preparation, mixing and preparation, molding, sintering and subsequent processing.
First, tungsten, nickel and iron powders need to be quantitatively poured into the reactor in a predetermined proportion to ensure that the powders are evenly mixed. Then, a corresponding proportion of resin binder is added for mixing. Next, by raising the temperature to 180°C, the resin binder is in a viscous flow state after heating, and is evenly mixed with the powder to prepare a viscous flow mixture.
Next, the extruder pipeline is connected to the material output pipeline of the mixing reactor, the mold is installed on the extruder, and the mold pipeline is connected. After designing the molding parameters, the pellets are extruded onto the prepared model through the extruder for rolling molding. During this process, the mold temperature is maintained at 100°C and the extruder temperature is maintained at 180°C. After the mold is rolled and formed, it is taken out and enters the degreasing process.
In addition, in order to ensure the quality and performance of the alloy, other subsequent processing steps may also be included in the production process, such as heat treatment, cooling, processing, quality inspection and testing. These steps help adjust the alloy’s structure, improve performance, and ensure that the final product meets the predetermined standards and requirements.
Please note that the specific production process may vary depending on the manufacturer, equipment, and technology. In actual production, adjustments and optimizations may also be required based on specific circumstances.
