Types and characteristics of construction machinery castings


The application and development of construction machine […]

The application and development of construction machinery castings will not last long due to the low cost of cast iron, good processability, and remelting and regeneration that can save resources and energy. For example, the exploration and development of cupola-electric furnace double smelting process and equipment; widely used molten iron desulfurization and filtration technology; manufacturing technology of thin-walled high-strength construction machinery castings; manufacturing technology of cast iron composite materials; cast iron surface or local strengthening technology; Fire ductile iron complete set of skills; using metal mold casting, metal mold sand casting, continuous casting and other special processes and equipment.

Production of construction machinery castings
The output of cast steel is relatively stable, but the quality, variety, performance of steel castings and the proportion of alloy steel and special steel continue to increase. Using various refining processes and techniques to develop new cast steel materials can improve the strength, toughness and special properties of the materials.

Forging Competition Gold
Due to a series of excellent properties such as low density, high strength and corrosion resistance, light alloys for construction machinery castings will be more widely used in various industries such as aviation, aerospace, automobiles, and machinery. Especially in the automotive industry, in order to reduce fuel consumption, the use of aluminum and nickel alloy castings instead of steel and iron castings is a long-term development trend. Among them, it focuses on the refining skills, metamorphism skills, grain refining skills and rapid detection skills before the furnace that are easy to operate. In order to further improve the performance of the material and maximize the potential of the material, high-quality aluminum alloy materials, especially aluminum-based composite materials, can be developed to meet the performance requirements of various working conditions. Strengthen the exploration of cluster alloy smelting process, improve the alloy die casting and squeeze casting process and the development of related techniques and explore the development of ferroalloy smelting equipment and related techniques and processes.

Construction machinery casting composite material
Composite materials will become a new engineering material in the 21st century. Casting composite materials will be devoted to the development and exploration of the base material and enhanced component materials of metal matrix composite materials, and will accelerate its application development and exploration.

The shortcomings of construction machinery castings are the main reason for rejects and are a serious threat to the quality of castings. For various reasons, there are various disadvantages in castings. During solidification molding, due to differences in conditions, the types and forms of defects and their manifestations are different. The solidification shrinkage of the liquid metal forms shrinkage holes and shrinkage. The redistribution of elements in the solid and liquid phases during solidification can lead to segregation. The concentration of thermal stress during cooling can lead to cracks and deformation of the casting.
