All iron melted via conventional techniques contains free-oxygen atoms. The amount of free-oxygen contamination varies depending upon the melting method and materials melted, but some free-oxygen atoms always exist. Free-oxygen atoms are detrimental to the quality of solidified castings. They offer no benefits – only bad consequences from their presence. Primary steelmakers deal with free-oxygen […]

The development of high-quality iron castings begins with melting processes and techniques. You control how it is melted, giving you the final call in determining its quality. Everything depends on you. Molten iron contains desirable and undesirable elements. In a ferrous foundry, you control both of these. From the scrap metal that is the raw-material […]
