A novel tuyere assembly for a metallurgical furnace is disclosed having a tuyere pipe formed of extremely high thermal conductivity and heat diffusivity materials, wherein a heat sink and a water cooled chamber, positioned exteriorly of the metallurgical furnace, extract heat from the tuyere tip through efficient heat conductivity along the tuyere pipe, so as to overcome problems of knurdle size control and tuyere pipe burn-back. |
