Title
Effect of Tuyere Angle on the Erosion of Acidic Fire Brick in anthracite cupola Operation
이영배 Yong Bae Lee
Abstract
Effects of tuyere angles range in 5°at 35° on melting velocity, tapping temperature and erosion of acidic fire brick had been studied in the Griffin type cupola operation using lump anthracite. The results were as follows: 1) Optimum tuyere angle was 20°. 2) Melting velocity was decreased as tuyere angle increase. 3) Tapping temperature was highest at 20° tuyere angle.
