Analysis of various types of precision casting materials

Kategorie: Allgemein – crushermachine2 – 03:49

Castings have a great influence on mechanical products. Mechanical properties depend to a large extent on the quality and performance of castings. Therefore, mechanical products have high requirements for castings. Mechanical products require that castings have working durability under different conditions, including Wear resistance, corrosion resistance, chilling heat, fatigue, shock absorption and other properties as well as machinability, weldability and other process properties. These quality properties have a direct impact on the working efficiency and service life of mechanical products. Different casting materials make the performance characteristics of the stainless steel casting itself different.
Cast steel production is relatively stable, while the quality, variety, performance of steel castings and the proportion of alloy steel and special steel continue to increase. The use of various refining processes and technologies to develop new cast steel materials can improve the toughness and special properties of materials.
Casting light alloys will be widely used in aerospace, aerospace, automotive, machinery and other industries due to their excellent density, high specific strength and corrosion resistance. In the automotive industry, in order to reduce fuel consumption and improve energy efficiency, the replacement of steel and iron castings with aluminum and nickel alloy castings is a long-term development trend. It focuses on solving pollution-free, high-efficiency, easy-to-use refining technology, metamorphism technology, grain refining technology and rapid pre-furnace detection technology. In order to further improve the material properties and maximize the potential of materials, high-quality aluminum alloy materials, especially aluminum-based composite materials, can be developed to meet the performance requirements of different working conditions, strengthen the research of cluster alloy technology, and continue the alloy die-casting and extrusion casting process. And research and development of related technologies; Improve the research and development of ferroalloy smelting equipment and related technologies and processes.
Composite materials will become a new type of engineering materials for the 21st century. Casting composite materials will focus on the development of metal matrix composite base materials and reinforcing and strengthening component materials, and accelerate the development of their applications.
Iron is our most common casting material. The low cost, high processability and remelting regeneration of cast iron parts save resources and energy, so the application and development of this material is enduring. Widely used advanced iron liquid desulfurization and filtration technology; Thin wall high strength cast iron parts manufacturing technology; Cast iron composite material manufacturing technology; Surface or local strengthening technology of cast iron parts; Isothermal fire ductile iron complete set technology; Metal casting and metal type Special techniques and equipment such as sand casting and continuous casting.
With the continuous development of the national economy, the performance requirements of mechanical equipment are getting higher and higher. Therefore, castings of important components that make up mechanical products also need to be improved and improved in terms of quality and performance, and the entire mechanical quality is improved from local quality. Product performance.
