Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary heat cooling of ductile iron castings, and in particular relates to an auxiliary heat cooling device for ductile iron castings. Background Art

[0002] Ductile iron castings are high-strength, wear-resistant and corrosion-resistant castings made of cast iron treated at high temperatures. Its main organizational structure is spheroidization, which can significantly enhance the toughness and strength of the castings, making them less prone to breakage, less prone to deformation, and strong in compression resistance. Ductile iron castings are usually composed of iron, carbon, manganese, silicon, copper and other elements. During the casting process, the carbides inside the castings are converted into spheres by adding spheroidizers. This spherical microstructure effectively alleviates stress concentration and improves the strength and toughness of the material. Ductile iron castings need to be specially cooled after production, so auxiliary heat cooling devices for ductile iron castings are used.

[0003] When the auxiliary heat cooling devices for ductile iron castings on the market are used, they mostly cool the ductile iron castings directly by water flow. However, since the surface of the ductile iron castings has been oxidized at high temperature to form an oxide film, the use of water flow cooling may destroy this oxide film due to the impact of the water flow, which may easily damage the castings and affect the quality of the castings.
