Utilization of Hydrogen Fuel in Reheating Furnace and its Effect on Oxide Scale Formation of Low-carbon Steels

Abstract

The transition from fossil-based fuel to hydrogen combustion in steel reheating furnaces is a possible way to decrease the process-originated CO2 emissions significantly. This potential change alters the furnace gas atmo sphere’s composition, impacting the oxide scale formation of the slab surface. Dynamic heating tests are per formed for three low-carbon steels using different simulated combustion atmospheres, including natural gas, coke oven gas, and hydrogen combustion in air, and hydrogen combustion in oxygen. Significant differences are found in the oxidation behavior of steel grades in the simulated hydrogen reheating scenario. A steel grade with low Mn content only has an 18% increase in oxidation between methane-air to hydrogen-oxygen methods, while it is 41% for a high Mn and Si steel grade and 65% for a high-Mn steel grade. Thus, in terms of material loss increase by oxidation, the transition of the heating method causes the least problems for the low-Mn steel grade.
