Anode pastes are widely used in the production of ferroalloys and primary aluminum and in other processes in the metal and chemical industries. In consideration that their manufacturing involves dosing and mixing, the properties and performance of the commercial product are determined by the type of initial charge components and their ratio. This study analyzed the composition of the initial charge mixtures of two anode pastes. At the initial stage, the solid carbon filler was separated from the pitch binder. The filler separated was classified by the components based on the difference in their physical properties and then divided into size classes. A comprehensive thermal analysis of the initial samples and the filler fractions was performed to evaluate the thermal transformations in the samples and to determine the filler–binder ratio in the charge. The extraction results of individual pitch fractions in the corresponding solvents were considered in the analysis. The charge mixture for two anode paste samples was analyzed to determine the possibility of using this approach. This approach can be developed further for possible applications in metal industry enterprises and in laboratory studies.

阳极糊料成分分析

阳极糊广泛用于铁合金和原铝的生产以及金属和化学工业的其他工艺。考虑到它们的制造涉及配料和混合，商业产品的特性和性能由初始进料组分的类型及其比率决定。该研究分析了两种阳极糊的初始充电混合物的组成。在初始阶段，固体碳填料与沥青粘合剂分离。分离出的填料根据其物理性质的差异按组分分类，然后分为尺寸等级。对初始样品和填料部分进行综合热分析，以评估样品中的热转变并确定装料中的填料-粘合剂比。分析中考虑了相应溶剂中各个沥青级分的萃取结果。分析了两个阳极糊样品的电荷混合物以确定使用这种方法的可能性。这种方法可以进一步发展，以用于金属工业企业和实验室研究中的可能应用。
