Abstract

Language:

This study focuses on the erosion pattern of blast furnace tuyere, a copper casted component essential for injecting hot air to facilitate the combustion of pulverized coal. The tuyere operates under high thermal conditions and features dual cooling circuits, with an emphasis on identifying the most vulnerable zones that survive operational challenges. By scanning used tuyeres, particularly those with a functional nose cooling circuit, the research identifies key erosion patterns compared against a three-dimensional model of the original tuyere. Findings indicate that the upper part of the nose front represents the weakest area, exhibiting the greatest material loss, attributed to the extreme temperature profile derived from numerical analysis. This research outlines potential manufacturing improvements for tuyeres to enhance their durability, suggesting future exploration into hard surface materials for cladding that could reduce erosion in the identified critical zones.
