Introduction to the characteristics of agricultural machinery castings?

Agricultural machinery castings are widely used, recognized for their various advantages and characteristics, and are easier to operate. Only by strictly following the operating regulations can good results be achieved. Let's learn about the characteristics of agricultural machinery castings together? If you want to know, come and take a look.

There are quite a few knowledge points that we need to know before using agricultural machinery castings, because only by mastering these can you operate better. Generally speaking, agricultural machinery castings have low costs, good processability, and heavy industry regeneration can save resources and energy. Therefore, the application and development of this material will not last too long. Such as cupola electric furnace dual melting treatment and equipment development; Therefore, it is currently widely used in the desulfurization and filtration technology of molten iron; Manufacturing technology for thin-walled high-strength cast iron; Manufacturing technology of cast iron composite materials; Surface or local hardening treatment of cast iron; The complete set of isothermal treatment for ordinary ductile iron adopts special treatments and equipment such as metal mold casting, metal mold sand casting, and continuous casting. Nowadays, agricultural machinery castings also have a series of excellent properties such as high strength and corrosion resistance, which will be widely used in industries such as aviation, aerospace, automotive, and machinery. Especially in the automotive industry, replacing steel castings with aluminum nickel alloy castings to reduce fuel consumption is a long-term trend. It focuses on simple refining techniques, modification techniques, grain refinement techniques, and rapid pre furnace inspection techniques. In order to further improve the performance of materials and unleash their potential, excellent aluminum alloy materials, especially aluminum based composite materials, can be developed to meet the performance requirements of various treatments.

In addition, it is also necessary to know that agricultural machinery castings can strengthen research on cluster alloy melting and processing, improve research on alloy die-casting and squeeze casting processing and related technology development, and research on ferroalloy melting equipment and related technology and processing development. Defects in agricultural machinery castings are the main cause of waste, posing a serious threat to the quality of castings. Due to various reasons, castings have various defects. Due to different conditions of agricultural machinery castings, the types and forms of defects also vary. This is because some liquid metals solidify and contract to form shrinkage pores. Segregation is caused by the redistribution of elements in the solid and liquid phases during the solidification process. The concentration of thermal stress during the cooling process can cause cracks and deformation in the casting. Corresponding measures should be taken based on the causes and degrees of the production of agricultural machinery castings to minimize the production of engineering machinery castings. In addition, agricultural machinery castings may have many defects such as debris, pores, and cold grids during the filling process. They are not only related to the type of alloy, but also to the specific forming process used. In short, the prevention and control of various defects is an important issue that cannot be ignored.
