The products is a ductile iron casting.
Cast ductile iron is a popular choice for farm machine support structures due to its high strength and durability, as well as its resistance to corrosion and wear. Some examples of farm machines that may use cast ductile iron support structures include tractors, plows, cultivators, harrows, and combines.
The use of green sand casting iron allows for the machines to withstand the rough and rugged conditions of farm work, while also providing a long-lasting and reliable support system for the machine's various components.
It is a traditional technology and widely used to use clay sand as casting molding material to produce castings. For example, the injection molding, semi-automatic molding, jolt molding, air impact molding and automatic molding machine on the casting process are also based on the use of clay wet molding sand as the premise. The implementation of various new technologies makes the position of clay wet molding sand more important in foundry production, but also makes the clay wet molding sand face many new problems, which prompts us to strengthen the research and deepen the understanding of clay wet molding sand.
Nowadays, with the rapid development of science and technology level, various production industries have an increasing demand for castings, and the quality requirements for castings are also higher and higher.
Green Sand Casting Iron needs attention:
In casting production, it is necessary to leave enough processing allowance to facilitate casting production without damaging the casting when machining. The specific reservation should be determined by drawings and materials.
In the modeling need to design a good drawing Angle, convenient mold from the casting; Also need to design good casting fillet, which is to prevent large steel castings in the wall connection and corner stress, crack, casting Angle damage and sand hole; In order to ensure that the core is fixed and vented in the mold, it is necessary to design the core head; Also consider the shrinkage of the casting cooling after pouring, so it is necessary to add this part of the shrinkage size in the mold.
