铝电解槽的大型化及高电流密度需要高质量的预焙阳极,相应地预焙阳极的检测指标从传统的5项增加到18项。近年来我国电解铝发展迅猛,对预焙阳极需求量快速增加,但生产阳极的原料沥青、石油焦、煅后焦质量却持续恶化,要生产出高质量的预焙阳极,需要生产厂家加强原料的检测。本文对预焙阳极生产过程中涉及的物料及最终产品的检测进行简单的概述。
Large size and high current densities in aluminum cells require high quality prebaked anodes, corresponding to an increase of pre-baked anodes from the traditional 5 to 18 measurements. In recent years, the rapid development of electrolytic aluminum in our country has rapidly increased the demand for prebaked anodes. However, the quality of raw bitumen, petroleum coke and calcined coke produced at the anode has continued to deteriorate. To produce high quality prebaked anode, it is necessary for manufacturers to strengthen raw materials The test. This article gives a brief overview of the testing of materials and finished products involved in the production of prebaked anodes.
