How to avoid the occurrence of agglomeration during the production process of molybdenum wire?

During the production process of molybdenum wire, the phenomenon of agglomeration can lead to issues such as decreased performance, changes in microstructure, and aesthetic defects. Agglomeration primarily occurs due to factors such as uneven distribution of raw material components, inadequate mixing, and improper sintering processes. To prevent agglomeration, comprehensive control is required across various aspects including raw material selection, mixing processes, sintering processes, heat treatment processes, and quality control systems.

The presence of impurity elements in raw materials can result in unstable performance during production. Therefore, ensuring the purity and uniformity of particle size distribution in raw materials is the first step in preventing agglomeration. During the mixing process, it is crucial to thoroughly blend various additive elements and molybdenum powder to ensure their uniform distribution. This can be achieved by extending mixing times, using efficient mixing equipment, and adding appropriate additives.

In the sintering process, it is essential to control sintering temperature and holding time appropriately to ensure thorough sintering of molybdenum powder while avoiding the volatilization or loss of additive elements. Insufficient sintering can result in defects such as pores and cracks within the molybdenum wire. Employing techniques like gradient heating sintering processes and atmosphere control can help improve the binding between molybdenum powder particles and the uniform distribution of additive elements.

During the heat treatment of molybdenum wire, it is important to control the atmosphere and temperature to prevent the agglomeration of additive elements during the process. Rational selection of heat treatment parameters such as heating rate, holding time, and cooling rate can improve the microstructure and performance of molybdenum wire.

Furthermore, establishing a rigorous quality control system can also prevent agglomeration. Developing detailed production process specifications and quality control standards for molybdenum wire production ensures clear operational requirements and quality standards at every stage. Regular maintenance and calibration of production equipment and processes maintain stability and reliability throughout the production process, thus avoiding issues that may arise.
