Abstract
Reheat furnace is an important component in hot milling process consuming large amount of fuel and energy. In order to investigate the operational effects on slab temperature distribution, a three-dimensional computational fluid dynamics (CFD) model was developed to simulate the flow characteristics, combustion process, and multi-scale heat transfer inside a reheating furnace with continuous slab motion. ANSYS Fluent®, which is a mature commercial package, was used to conduct numerical simulation. The operation process was modeled with specific slab line-ups and fuel input conditions. The slab motion was modeled with dynamic mesh based on a transient heating process. The model was validated with measurement data at the ArcelorMittal hot rolling mill. The model aims to predict the temperature field in the furnace and the temperature evolution of the slab as it travels through the furnace.
