Abstract

Abstract

A statistical analysis on the compositions of inclusions in high carbon wire rod produced by one steel company was conducted. And the compositions of low melting point inclusions of Al₂O₃-SiO₂-MgO-CaO-MnO system in a high carbon wire rod steel with Al-Si-Mn deoxidization were calculated and analyzed by the thermodynamic software FactSage. In the low melting point zone of the Al₂O₃-SiO₂-MgO-CaO-MnO system for a high carbon wire rod steel, the Al₂O₃ content should reach 56%, and CaO 20%~30%.
