Computer Simulation of Thermal and Stress-Strain State of Blast Furnace Tuyeres

Resumo

A research has been conducted to study the effect of the thickness of a thermal insulation insert inside the air passage of a blast furnace tuyere and the size of the air gap separating it from an inner sleeve on the temperature distribution and stresses within such insert and inner sleeve. A steady-state problem was solved in MS Excel, a non-steady-state problem – in DEFORM-2D, and both the steady-state and non-steady-state problems – in Ansys Fluent. A Static Structural modulus was used in Ansys to calculate stresses. The insert thickness values were assumed to be 10 and 13 mm, and the size of the air gap was 0, 1, and 2 mm.
