Optimization of Refractory Lining Used In Blast Furnace

Abstract

The refractory lining with stave 3D model in blast furnace is analyzed and design by using the ANSYS software. This model is used for analysis the effect of refractory lining thickness with different cooling rate. The cooling of refractory is the essential feature for the blast furnace campaign life. The cooling of refractory lining can be done by stave cooler. It is cooling device that maintain the innermost profile of blast furnace. The refractory materials which are used in this experiment are aluminum oxide and silicon oxide with different stave materials is copper, aluminum and cast iron. The experimental data are collected from Rourkela steel plant for developing a 3D model of refractory lining of stave cooling. The refractory lining thickness of the blast furnace is in use as 650 mm. Stave material used such as aluminium and copper. Water is used as a cooling agent.
