Effect of temperature on the relative importance of surface condi- tion and furnace atmosphere in the oxidation of carbon steels

摘要

Controlled reheating tests have been carried out to determine the relative importance of surface condition and furnace atmosphere on scale growth in steel processing routes as a function of temperature. Isothermal and continuous heating thermobal-ance tests were conducted on three different plate grade steels in five different test atmospheres. A qualitative Taguchi analysis was applied to determine the effect of different test variables on the observed oxidation rate. The steels were a conventional plate grade and low silicon and weathering steel variants.
