Latest company news about Which is the most critical step in the whole casting process of the wear-resistant hammer?

Do you know how the wear-resistant hammer head is cast? What is the solidification process of the hammer head? By measuring the temperature-time curve of the alloy hammer casting during the cooling process of the mold, it is determined what the solidification state of the crusher hammer is from the surface to the center at a certain moment, that is, where the layers are on the cross section of the alloy hammer casting. State: liquid, solidified, solid. Castings are solidified in three main ways.

①Laminar solidification: The hammer casting solidifies layer by layer from the surface to the inside, and its liquid-solid coexistence area, that is, the mushy area, is small, such as the solidification of pure aluminum.

② Paste solidification: The whole or most of the solidification is carried out in the coexistence area of ​​liquid phase and solid phase. Such as ductile iron, tin bronze solidification.

③ Intermediate solidification method: During the solidification process, the liquid coexists in the liquid phase, the paste and the solid phase. It is a solidification method between layered solidification and paste solidification, which is the solidification method of most casting alloys, such as the solidification of gray cast iron and carbon steel.

In short, the hammer head of the crusher is effectively compounded by solid and liquid, so the solidification process is also a very critical step in the entire casting process. Cracks, pores and other defects will inevitably appear in the hammer head of the crusher during use, which can be avoided by simple methods. Gongyi Dingcheng liquid alloy composite hammer head has excellent comprehensive performance, and we strictly control the production process and production process. It will take a lot longer to use!
