Modeling of the Temperature Field of Blast Furnace Tuyeres Using Deform-2D Software

摘要

The effect of the insulation liner in the tuyere with and without air gap and the thermal-spray coating on the temperature field of the blast furnace tuyere is studied. Deform-2D software is used to analyze the dynamics of heating of the tuyere (axisymmetric problem). It is shown that the insulation liner and the air gap between it and the tuyere affect strongly the temperature field of the tuyere. The burnout of the tuyere contacting with hot iron is simulated as an example.
