一九八七年九月在长春举行的第三届全国发明展览会上,我院冶金系的科研成果《低温炼锑》,经大会评审委员会严格的审议,被评为本届发明展览会金奖。《低温炼锑》新工艺,对现行炼锑方法进行了全面变革,所据原理也有所不同。此工艺使炼锑过程中的焙烧和还原等主要工序均在较低的温度下完成,不加辅助材料,不造熔渣。从而使金属锑质量稳定,金属回收率极高。而且冶炼过程在封闭条件下连续进
At the Third National Invention Exhibition held in Changchun in September 1987, the scientific research achievement “Low-temperature Refractory Antimony” of the Department of Metallurgy in our hospital was scrutinized by the appraisal committee of the General Assembly and was awarded the gold prize of the exhibition of inventions . “Low temperature refining antimony” new technology, the existing method of antimony refining a comprehensive change, according to the principle is also different. This process makes the main processes of roasting and reduction in antimony refining process are completed at a lower temperature, without auxiliary materials, do not make slag. So that the quality of metal antimony stability, high metal recovery. And smelting process in closed conditions into the continuous
