一、前言目前大量生产的稀土硅铁合金,主要是用做钢铁中的变质剂。其变质效果很强,所以提高合金中铈含量,对提高合金的变质效果是有意义的。二十世纪六十年代,美国福特矿业公司就开始了研究碳还原氢氧化铈生产铈硅铁合金,定名为CSF—10合金,其化学成分为Ce9—11%,Si36—40%,总稀土RE12—15%,其余为铁。这种合金既可做灰铸铁孕育剂,也能做球墨铸铁的球化剂;英国
First, the preface At present, mass production of rare earth ferrosilicon alloy, mainly used as steel in the metamorphic agent. The metamorphic effect is very strong, so to improve the cerium content of the alloy, to improve the metamorphic effect of the alloy is significant. In the 1960s, the American Ford Mining Company began to study the production of cerium-silicon-ferroalloys by carbon-reduced cerium hydroxide, and named CSF-10 alloy. Its chemical composition is Ce9-11%, Si36-40%, total rare earth RE12- 15%, the rest is iron. This alloy can do gray cast iron inoculant, but also can do nodular cast iron nodulizer; United Kingdom
