With the continuous development of the global ship trade, the demand for the production of mechanical forgings in ship ports is also growing. Due to the limitations of traditional forging technology, such as low production efficiency and material waste, it is necessary to seek new production technology to meet the market demand. Powder metallurgy technology, as an advanced material preparation technology, has a broad application prospect in the production of mechanical forgings in ship ports.
Powder metallurgy is a technique for preparing materials and products by sintering and forming metallic powders or mixtures of metallic powders and non-metallic powders. Powder metallurgy technology can achieve precision molding and near-net molding by adjusting the composition, particle size, molding pressure and other parameters of raw material powder according to product performance requirements. In addition, powder metallurgy technology can also realize the rapid solidification of materials, nanomaterials preparation, etc., and has broad application prospects.
The application of powder metallurgy technology in the production of mechanical forgings in ship ports mainly includes the following links:
Preparation of powder: Through atomization, mechanical grinding, chemical reduction and other methods to prepare metal raw materials into powder.
Molding: The powder is filled into the mold, and the external force is applied to form a certain shape and size of the powder in the mold.
Sintering: the billet is sintered at high temperature, so that the metallurgical bonding between the powder particles occurs, forming a dense metallurgical structure, and improving the strength and stability of the billet.
Follow-up treatment: work hardening and heat treatment of the sintered billet to meet the performance requirements of the final product.
Powder metallurgy technology has the following advantages in the production of mechanical forgings in ship ports:
Improve the quality of forgings: powder metallurgy technology can achieve precision forming and near-net forming of materials, reduce or avoid the material waste and density inequality problems in traditional forging technology, and improve the quality and stability of forgings.
Improve production efficiency: the preparation and molding process of powder metallurgy technology can achieve automated and continuous production, reduce production costs and improve production efficiency.
Reduce energy consumption: Since powder metallurgy technology does not require repeated forging and heat treatment, it can reduce energy consumption and achieve energy saving and emission reduction.
To achieve material functionalization: by adding alloying elements in the powder or surface coating treatment, metal materials and functional materials with special properties can be prepared to meet the different needs of ship port mechanical forgings.
Powder metallurgy technology has a broad application prospect in the production of mechanical forgings in ship ports, and it is also widely used in other fields. For example, powder metallurgy technology is used in the manufacture of aircraft engines to prepare high-performance turbine blades, turbine disks and other key components; In automobile manufacturing, it is used to produce high-performance engine cylinders, pistons and other key components; In the field of medical devices, it is used to produce high-precision and high-stability implants and medical devices. The application of these fields has further expanded the wide application of powder metallurgy technology.
The introduction of powder metallurgy technology in the production of mechanical forgings in ship ports is of great significance to improve the quality of forgings, reduce the production cost, improve the production efficiency, energy saving and emission reduction. The precision forming and near-net forming ability of powder metallurgy technology and its advantages in material functionalization make it widely used in ship port mechanical forging production and other fields. With the continuous development of science and technology, powder metallurgy technology will be more widely used and promoted in the future, providing more powerful technical support for industrial development in various fields.
