1, the hardness is very uniform;
2. This series of cast iron castings have good wear resistance and high toughness value;
3. Strong impact resistance
In addition, we are equipped with a refining furnace, which can be configured according to user requirements for large-scale ductile and gray iron castings with corresponding chemical compositions.
Welcome friends from all walks of life to visit, guidance, to discuss cooperation.
Construction machinery castings can save resources and energy due to the low cost of cast iron, good process, and remelting and recycling, so the application and development of this material will not last for a long time. For example, the exploration and development of cupola-electric furnace double smelting process and equipment; Widely used molten iron desulfurization and filtration techniques; Thin-walled high-strength engineering machinery casting manufacturing technology; Cast iron composite material manufacturing technology; Cast iron surface or local strengthening technology; Isothermal normalizing ductile iron complete set of technology; Special processes and equipment such as metal mold casting, metal mold sand mold casting and continuous casting are adopted.
(B) Production of construction machinery castings
The output of cast steel is relatively stable, but the quality, variety, performance of cast steel and the proportion of alloy steel and special steel continue to increase. The use of various refining processes and techniques to develop new cast steel materials can improve the strength, toughness and special properties of the material.
(c) Casting Competition Gold
Engineering machinery casting light alloy due to low density, high strength, corrosion resistance and a series of excellent characteristics, will be more widely used in aviation, aerospace, automotive, machinery and other industries. 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. It focuses on solving the simple operation of refining techniques, metamorphic techniques, grain refinement techniques and furnace rapid detection techniques. In order to further improve the material performance and maximize the potential of the material, we can develop high-quality aluminum alloy materials, especially aluminum matrix composite materials, to meet the performance requirements of various working conditions. Strengthen the exploration of cluster alloy melting process, improve the development of alloy die casting and squeeze casting process and related techniques, explore the development of ferroalloy melting equipment and related techniques and processes.
(d) Composite materials for construction machinery castings
Composite material will become a new engineering material in the 21st century. Casting composite material will devote itself to the development and exploration of metal matrix composite material base material and reinforced component material, and will speed up its application development and exploration.
The shortcomings of engineering machinery castings are the main cause of waste and a serious threat to the quality of castings. Due to various reasons, there are various shortcomings in the casting. Solidification molding, due to the differences in conditions, the types of forms and manifestations of different parts of the shortcomings. The solidification shrinkage of the liquid metal forms shrinkage pores and shrinkage. The redistribution of elements in the solid and liquid phases during solidification leads to segregation. The concentration of thermal stresses during cooling can cause cracking and deformation of castings.
According to the cause and degree of occurrence, corresponding measures should be taken to eliminate or minimize. In addition, many shortcomings, such as debris, pores, cold, etc., occur in the filling process, they are not only related to the type of alloy, but also related to the specific molding process. In short, to prevent, eliminate and control various shortcomings is an important issue that cannot be ignored.
