The Modeling of the Gas Flow and Its Influence on the Scale Accumulation in the Steel Slab Pusher-type Reheating Furnace

Year: 2003

Type: article

Abstract: The gas flow in the pusher-type reheating furnace coupled with fluid dynamics, combustion and radiation was modeled in this work. CFD Simulation results described a detailed flow distribution in the steel reheating furnace and indicated a reverse flow existing under the slab near the burners in the lower heating zone. This reverse flow could be the main reason for the scales accumulation in the front part of the heating zone. The oxygen distribution in the furnace was also calculated and the mass fraction is about 4%. The oxygen distributes uniformly inside the most parts of the furnace except the areas near the burners.
