“…In this study, it is assumed that the deformation of steel during the rolling process was uniform and the rolling parameters in different heats were similar. Wang 5,28) et al proposed that there are dual-phase inclusions (MnO-SiO 2 -Al 2 O 3 ) in tire cord steel, and these inclusions with different deformability became gradually separated from each other during hot rolling. Therefore, the main factors affecting the evolution of oxide inclusions in different heats during hot rolling were the differences related to homogeneity and melting points.…”

“…Kimura 27) suggested that all the oxide inclusions (alumina, zirconia, zircon and silica) were fractured during hot rolling and its magnitude could be predicted from the Young's modulus and the mean atomic volume of the oxides. Wang 5,28) found that the formation of SiO 2type inclusions in wire rods was due to the precipitation of SiO 2 in the formed MnO-SiO 2 -Al 2 O 3 inclusion during casting and then separated during rolling. Zhang et al 29,30) proposed that deformation is related to the chemical composition and values of the Young's module for the inclusions.…”

“…A large number of different types of inclusions exist in the wire, such as Al 2 O 3 , 18 MgO·Al 2 O 3 , 26 2SiO 2 ·Al 2 O 3 , 27 SiO 2 , 28 and their mixtures 28–30 . They have different hardness, which depends on the elastic modulus of inclusions.…”

Inclusion is one of the main causes for unqualified wire. However, the forming mechanism of drawing fracture due to inclusions is still unclear. Therefore, it is significant to figure out the forming mechanism of wire drawing fracture with inclusions for designing and manufacturing high‐quality wires. In this paper, a physical model of wire with inclusion is established based on experimental observations. Multipass drawing is simulated by using finite element method (FEM) with the developed numerical damage modeling. Numerical results demonstrate that the damage increases with the development of drawing progress, and the damage caused by high elastic modulus of inclusion is greater than that of low elastic modulus. Pen‐tip shaped fracture of wire with inclusions is mainly caused by the superposition of core and external V‐shaped damage. Furthermore, the core V‐shaped crack will propagate along the external V‐shaped damage area.

“…However, the Si–Mn killed steel is drawn at room temperature, thus, the deformability or fracture of inclusions during cold drawing should no longer have a direct relationship with the melting temperature. In recent years, current authors [ 7,10 ] and Wang et al [ 12 ] proposed that inclusions in the Si–Mn killed steel should be controlled to those with small Young's modulus to promote the deformation and fracture of inclusions during the cold processing of steel. The intrinsic reason for that was also discussed.…”

The existence of the dissolved aluminum and other impurity elements in alloys would inevitably lead to the formation of the Al2O3 component of inclusions in Si–Mn killed steels. Herein, the effect of dissolved oxygen at the endpoint of basic oxygen furnace (BOF) on the control of inclusions in a Si–Mn killed steel is investigated. With the increase in the dissolved oxygen at the BOF endpoint, the (FeO + MnO) content in the refining slag increases and the dissolved aluminum in the steel decreases as a whole. Meanwhile, the proper increase in the dissolved oxygen hardly deteriorated the cleanliness of the steel. As the equilibrium dissolved oxygen at the BOF endpoint increased from 148 to 402 ppm, the Al2O3 content of inclusions could be lowered to <4 wt%. Both industrial trials and the thermodynamic consideration indicate that increasing the dissolved oxygen at the endpoint of BOF can be an efficient approach to achieve the ultralow Al2O3 content of inclusions in the Si–Mn killed steel due to the oxidation of the dissolved aluminum by the oxygen both in the molten steel and in the refining slag.
