自热法生产二氧化锡

Production of Tin Dioxide with Autothermic Process

借鉴熔池熔炼技术设计了一套自热熔炼装置生产二氧化锡,产品用于玻璃电极。实际生产证明,产品粒度、纯度和白度均能满足要求;渣可循环使用而量不增加;除开炉时锡锭加热融化升温需天然气燃烧加热外,生产过程不需要任何燃料,设备运行稳定可靠,真正实现了自热熔炼。

An autothermic smelting system was designed based on bath smelting technology to produce tin dioxide for glass electrodes. Plant practice shows that the grain size, purity and whiteness can meet the re- quirement. Slag is recycled with no increase of quantity. There is no need for any fuel apart from tin ingots melting with nature gas at the beginning of production. Equipment operation is stable and reliable.
