Sponge Iron
Ispat's sponge iron is manufactured at one of the most efficient Sponge Iron plants in the world. The plant has been certified for ISO 9002 (1994) and ISO 14001 (1996).
Applications
Steel is normally produced to meet the specific application-oriented criteria, keeping in view its chemical composition and mechanical properties. However, residuals influence the character of steel, including internal cleanliness, surface finish and the processing conditions used during casting, hot rolling, cold rolling, heat treatment, and final finishing.
For a given application, there may be many variations in steel chemistry from one supplier to another, but there remains a grouping or proportion of non-refinable metallic elements such as copper, tin and nickel, among others, upon which a maximum limit is placed for the best quality results. In the case of Ispat Hi-Q Sponge Iron, all these elements come across in traces only, and its chemical composition by and large, remains consistent, enabling the users to produce the best quality steel.
