过去,我厂铝合金的熔炼是分两次进行的,其中的二次熔炼及保温使用的是井式煤气炉。这种炉因其炉底未彻耐火砖,炉壁保温措施不好;助燃空气是由鼓风机直接吹入的冷空气;燃烧咀位置离炉膛中心太近。所以,热能消耗大,坩埚使用寿命短。为了克服井式煤气炉的上述缺点,我们设计了一种涡流式煤气 In the past, the smelting of our aluminum alloy was carried out in two stages, of which the second-stage smelting and thermal insulation used a pit type gas furnace. This furnace is not completely refractory bricks because of its bottom, furnace wall insulation measures are not good; combustion air is blown by the blower directly into the cold air; combustion Tsui position too close to the center of the furnace. Therefore, the heat consumption, crucible life short. To overcome the above shortcomings of a pit gasifier, we designed a vortex gas
