What is the yield loss of reheated steel?

During the heating of steel in the reheating furnace, hot steel surfaces react with the in-furnace oxidizing atmosphere resulting in the formation of an iron oxides layer known as scale. The yield loss due to this phenomenon can range from 1.0 % to 3 % of reheated steel.See all results for this questionWhat is scale formation in furnace?A major element in this complexity of scale formation is the inconsistency, which again, is a result of interacting parameters in the reheating furnace. A saving of up to 35 % of steel lost to scale can be achieved by reducing the excess air in the furnace from 70 % to 20 %.See all results for this questionWhat is recrystallisation annealing?Thus, commonly, recrystallisation annealing of carbon steels is done at 650°C to 680°C, whereas of high carbon alloy steels (Cr, Cr-Si, etc.) is done at around 730°C for 0.5 to 1.5 hours. Coarse grained steels may be refined to produce fine-grained steels by heavy cold-working and recrystallisation-annealing.See all results for this question
