1.前言 南京钢管厂原铝合金熔炼炉为矩形火焰反射炉,用未经筛分的原煤为燃料,水平炉条人工间断加煤层状燃烧。为满足节能、环保和冶炼高质量变形铝合金的要求,与我院合作研制成功新型铝合金熔炼炉。其特点是燃用热混合发生炉煤气和热空气,圆形炉膛、架空炉底当烟道、高速火焰贴靠熔池镜面沿炉壁旋转,既加强了对流传热又搅拌了
1. Introduction Nanjing Steel Tube Plant The original aluminum alloy smelting furnace is a rectangular flame reverberatory furnace, which uses the raw coal without screening as the fuel, and the horizontal horizontal slab is added with artificial intermittent coal-bed combustion. In order to meet the requirements of energy saving, environmental protection and smelting of high quality deformed aluminum alloy, we successfully developed a new type of aluminum alloy smelting furnace with our institute. The utility model is characterized in that the combustion gas and the hot air are mixed with the hot mixed furnace gas, the circular hearths and the overhead furnace bottom flue and the high-speed flame are rotated along the wall of the furnace mirror to reinforce the convection heat and the stirring
