Inclusion in the liquid high carbon steel after ladle treatment


Figure 1: Inclusion in the liquid high carbon steel after ladle treatment. SEM, scale bar: 10 µm.

Inclusion name: Oxide inclusion
Record No.: 853
Inclusion formula: No data
Inclusion type (Macro/Micro/Nano): Micro
Inclusion type (Exogenous/Indigenous): No data
Inclusion classification: Oxide
Inclusion composition in weight %: No data
Sample: High carbon wire rod steel
Steel composition in weight %: 0.70-0.80% C, 0.65-0.70% Mn, 0.16-0.30% Si, max. 0.020% P, max. 0.020% S, max. 60 ppm N.
Note: Inclusion characterization of the corresponding liquid steel samples established the origin of above non-deformable inclusions to the deoxidation process itself (Fig. 1). In spite of large scatter in the data, most of the inclusions found in liquid steel samples corresponded well with those of the corresponding wire rod samples.
