The effect of the content of Cu, Pb, Fe, Sn and Si on the properties of 445 commercial batches of brass ribbon subjected to continuous annealing to a soft condition is studied. The active system of control of the composition and properties of processed batches is updated, and a regression dependence of the properties of the ribbon on the content of lead, iron, tin and silicon impurities in it is determined. Numerous sets of initial data are used to obtain different models describing the dependence of the properties of the ribbon on the chemical composition. The effect of the Si impurity on the properties is shown to be dominant. Recommendations are given for organization of preventive control of the composition of the alloy (the content of Si) in the foundry stage and selection of ingots meeting the condition Si ≤ 0.05% for the production.

研究了 Cu、Pb、Fe、Sn 和 Si 的含量对 445 批商品化黄铜带连续退火软态性能的影响。更新处理批次的成分和特性的主动控制系统，并确定带材特性对其中铅、铁、锡和硅杂质含量的回归依赖性。许多初始数据集用于获得不同的模型，描述带的特性对化学成分的依赖性。Si杂质对性能的影响显示出占主导​​地位。对铸造阶段合金成分（Si含量）的组织预防控制和选择满足Si≤0.05%条件的铸锭进行生产提出了建议。
