Paper Title:
Study on Smelting High-Al Cold Heading Steel SWRCH6A Using Single-Slag Process
  Abstract

Based on the actual process for smelting cold heading steel, this article adopts the single-slag process to smelt the low-carbon, low-silicon and high-alumina cold heading steel SWRCH6A, so as to study the effect of technological factors of the smelting process on the change of molten steel component in various working procedures and steel properties. The results show that, the smelting process control level for smelting high-Al cold heading steel using single-slag process is improved, the content change for main elements in the steel, w[Al]t and calcium treatment effect are stable, w[C] and w[Si] have a close relationship with w[P] and w[S]. The calcium yield after calcium treatment by single-slag process has a linear relation with w[Ca], and ηCa=2323.4*w[Ca] -1.040. The maximum calcium yield may reach 21%. All the mechanical properties of cold heading steel exceed the ML08Al standard. The smelting cold heading steel using single-slag process can fully reach the property requirements for cold heading steel grade.
