Abstract

In this present study of Blast furnace cooling stave with the refractory lining, the three-dimensional stave cooler with Refractory linings of a blast furnace has been model and analysed. Further, this model has been utilized for the heat transfer analysis of different thickness of Refractory lining materials (i.e., 0.65m to 0.55m). The heat dissipation and temperature variation by the 3D model are examined by using finite volume method. The Mullite bricks have considered as a Refractory lining, which contents 65% of Al2O3 and 35%of SiO2 and three different stave cooler material has chosen for this analysis, which are Cast iron, copper and aluminium respectively. Subjected Stave cooler identified in Rourkela steel plant (blast furnace #4) in Bosh zone, in this zone, the maximum heat load is obtained. The Experimental data collected from Rourkela Steel Plant is used for developing a 3D model of heat transfer analysis of subjected stave cooler with refractory lining. Further, nitrogen is considered as a cooling agent instead of water due to an abundance of nitrogen available in the steel industry.
