Effect of the burner arrangement on Slab reheating characteristics in a reheating furnace

Slab reheating characteristics in the walking beam type reheating furnace were studied by using the finite volume method (FVM). A geometry model for simulating the gas circulation, heat transfer and slabs reheating process in a reheating furnace was developed by using ANSYS FLUENT software. Usually, slabs are heated in the furnace, and temperature values of the slabs reach above 1,500 K. After that, they are transported to the rolling mill. The slab reheating in a reheating furnace is influenced by many factors, such as gas velocity, moving speed of the slabs, and burner arrangement. Especially, the arrangement of burners shows a great effect on reheating the slabs. In the paper, the main object of study is to investigate the temperature distribution in the reheating furnace by considering the effect of the burner position. In addition, it is found that the temperature fields of the slabs are significantly affected by changing the positions of the burners
