Design and production application of ductile iron casting

- Apr 12, 2019-

The energy-saving requirements of ductile iron casting during its use lead to its basic redesign of the parts, so that it can achieve its advantages of light weight and high efficiency to a certain extent. Ductile iron casting is often used for the production of complex forces, strength, toughness, wear resistance, etc. Highly demanding parts, such as crankshafts and camshafts for automobiles, tractors, internal combustion engines, etc., as well as medium-pressure valves for general machinery.

In the use of high-strength and low-alloy in the use of ductile iron casting, in addition to the research on copper and molybdenum, nickel and niobium have been studied. Although the manganese fiber ductile iron casting is not stable enough in performance, it has achieved remarkable economic benefits for many years of system research and production applications.

In the high-strength low-alloy ductile iron casting, in addition to the research on copper and molybdenum, nickel and niobium have also been studied. Although the manganese fiber ductile iron casting is not stable enough in performance, it has achieved remarkable economic benefits for many years of system research and production applications.

In the heat-resistant ductile iron casting, in addition to the medium silicon ductile iron casting, the influence of the total amount of Si+Al on the growth resistance of the rare earth magnesium ductile iron casting was systematically studied. Progress has also been made in high-nickel austenitic ductile iron casting, which has been successfully applied in petroleum mining machinery, chemical equipment, and industrial furnace devices.
