我厂蒸馏锌粉生产原来一直沿用三十年代的坩埚炉,生产过程劳动强度大,劳动环境十分恶劣,生产效率低,金属损失大,产品质量低,阻碍着生这种炉子的主要特点是利用碳化硅砖既耐高温,又具有良好的导热性,采用碳化硅砌筑拱顶的蒸发室设置在燃烧室的下部,原料1～4号锌锭从炉侧门加入熔化池,锌块熔化后通过两次反口进入蒸 The original production of distilled zinc powder in our factory has been using the crucible furnace of the thirties. The production process is labor-intensive, the working environment is very harsh, the production efficiency is low, the loss of the metal is large, the quality of the product is low, which hinders the main feature of the furnace. The silicon carbide brick has high temperature resistance and good thermal conductivity. The evaporation chamber with the silicon carbide masonry vault is arranged at the lower part of the combustion chamber. The raw ingots 1 to 4 are added to the melting pool from the side door of the furnace, Two anti-mouth into the steam
