Effects of Alternative Reheating Pathways on Steel Oxidation and Copper Hot Shortness
Abstract
Steel reheating is mostly fueled by natural gas, but alternative heating with electricity and hydrogen combustion are promising alternatives. Changes to the furnace environment will affect steel oxidation, and in recycled scrap steel containing copper, hot shortness defects. Hot shortness occurs because copper enriches at steel surface during oxidation, eventually forming a copper-rich liquid phase that wets grain boundaries and causes cracking. This paper provides initial results to assess the impact of changes in heating sources on oxidation kinetics and copper enrichment.
