摘要
阐述了不锈钢厂对400系除尘灰（Cr9％、Ni0.8％、Fe38％）和氧化铁（Cr11％、Ni5％）按比例混和预处理,以焦炭为还原剂,渣碱度控制在1.3～1.7后,生产出Ni≥2.3％、Cr≥18％、Si≤4％、P≤0.045％的低镍铬生铁,实现不锈钢除尘灰和固体废渣氧化铁的再生利用.
It discusses the pretreatment which mixes 400 series dust （Cr9%, Ni0.8%, Fe38%） with iron oxide （Crl 1%, Ni5%） in proportion by stainless steelmakers. Coke as the reductant, under the basicity of 1.3-1.7, low nickel chromium pig iron （Ni≥2.3%, Cr≥ 18%, Si≤4%, P≤0.045%） can be produced. It realizes the recycling of stainless steel dust and solid waste slag iron oxide.
