The Correlation between Non-metallic Inclusions and Machinability in Free Cutting Structure Steels

摘要: 本文以鈣硫系易切削結構鋼為主要研究對象,借助于定量圖像分析儀、電子探針、掃描電鏡等儀器和設備,探討了鋼中非金屬夾雜物與鋼切削性能的相關性。研究鋼中非金屬夾雜物尺寸對刀具壽命的影響,結果表明:本試驗條件下夾雜物對刀具壽命的臨界影響尺寸為8μm。還研究了非金屬夾雜物的間距、均勻性及數量對刀具壽命的影響。
最后,建立了描述非金屬夾雜物特征參數與刀具壽命關系的數學模型。
試驗表明,刀具壽命（T）主要受鋼中非金屬夾雜物有效顆粒數（Ne）和分布均勻度（H）的影響。

Abstract: By using the quantitative image analyzer, EPMA, SEM et al, the effects of the size, inter-distance, homogeneity and number of non-metallic inclusions mainly in Ca-S free cutting structure steel on tool life were studied.The results show that the critical length of non-metallic was 8 μm under this experimental conditions.
A mathematical model describing the relation between the parameters of non-metallic inclusions and tool life was set up:
T=α·Hβ·Ne^γ
According to the model, the tool life(T) dePends mainly on effective number(Ne) and homogeneity(H) of non-metallic inclusions in steels.
