Abstract

It is shown experimentally and computationally that the elongation of the insulation liner in the air passage to the tuyere nose reduces substantially the heat losses with cooling water. To improve its efficiency, it is reasonable to make the liner thickness uniformly decrease from the flange to the nose and to apply slurry coating to the inner surface of the liner. Improving the liner design allowed reducing the heat losses by 26.2% compared with commercial liner and increasing its life by a factor of 1.9 compared with the elongated liner with constant thickness in the inner shell and variable thickness in the nose.
