SRIF, CHINA.
Hydro turbine castings

Established in 1957, Shenyang Research Institute of Foundry (SRIF) is the largest state foundry institute in China.

The special steel castings are manufactured by utilizing electric-furnace plus AOD duplexing technique, which can maintain the Ni4 series stainless steel content up to the requirements of commercial applications yet limiting the content of impurity and gas within a minimum level( [P,S] =0.04%,[N] =70ppm,,[O] =40ppm).
Thanks to the special heat treatment, the strength, hardness and yield-tensile ratio of castings produced with low carbon lath martensite are greatly enhanced. In recent years, the technology has been successfully applied in manufacturing of flow passages components for hydro-turbine, such as wicket gate, Francis crown, Francis band, Kaplan and Francis blade with a wide range of sizes, Pelton, Kaplan and Francis turbine runner etc. The product capacity is 1000 tons per year. Other special steel products include the castings with boron applied in nuclear power station and all components of heat-resistant, corrosion-resistant and wear-resistant materials.
