Analysis on Gas Flow Field in Bell-Type Annealing Furnace by Using FLUENT

Abstract:

Because temperature decreases sharply, expansion caused by heat and contraction caused by cold are evident, the air in furnace is disturbed greatly and the zone of negative pressure may appear during bell-type furnace annealing. The zone can cause external air permeating the furnace and make steel coil annealed. Therefore it is necessary to analyse the flow field of protective gas in furnace during cooling, whether the air zone of negative pressure can form, the location of the zone and the methods of eliminating the zone. In addition, splitter plate disturbs the flow of gas and its effect on disturbed air is also analyzed. This paper analyses flow field in bell-type annealing furnace by using FLUENT, whether the zone of negative pressure exists and its location.
