摘要

为对H13模具钢切削废屑加以回收利用

提高Cr、Mo、V等合金元素的回收率

采用50 t中频感应炉-LF-VD流程对切削废屑进行返回法熔炼H13钢。分析了固化压块和低真空熔化工艺对Cr回收率的影响和CaO-BaO复合渣系BaO含量对脱磷效果的影响。结果表明

对废屑进行固化成块处理、采用≤1 333 Pa低真空熔化

可以将废屑中Cr、Mo、V的回收率提高到96%以上

与用未压制的切削废屑熔炼相比

节约熔化时间25 min/炉

在熔化期采用高碱度的CaO-20%BaO复合渣系进行除磷

可以将产品中P含量控制在0.01%。

Abstract

In order to recover and apply the cutting scrap of die steel H13 and increase the yield of Cr

V etc alloy elements

the die steel H13 is melted by return cutting scrap method in 50 t medium frequency induction furnace- LF- VD flowsheet. The effect of curing pressed block and low vacuum melting process on Cr yield and the effect of BaO content in CaO-BaO compound slag series on dephosphorizing results are analyzed. Results show that with curing pressed block treatment and melting on ≤1 333 Pa low vacuum condition the yield of Cr

Mo and V in cutting scrap increases to more than 96%

as compared with non-using curing pressed block treatment

the melting time decreases by 25 min/heat. During melting period

dephosphorization process is carried out by high basicity CaO-20% BaO compound slag series

the P content in products shall be controlled to 0. 01%.
