铜连铸连轧工艺生产对其原料——电解铜提出了更高的质量要求。而电解铜中氢的存在则被认为是一个影响铜连铸产品质量的最显著的因素。氢与晶粒周围杂质发生协同作用造成在热轧铜材中出现过度的裂纹。本文包括:胶、硫脲这两种主要有机添加剂对阴极超电压的影响和阴极铜中氢含量与电解槽阴极超电压成正比。并提出:实际生产中,最佳超电压范围-30mV以下,在这个范围内,阴极铜杂质氢含量可以维持在1
Copper continuous casting and rolling production of its raw materials - electrolytic copper put forward higher quality requirements. The presence of hydrogen in electrolytic copper is considered to be one of the most significant factors affecting the quality of copper continuous casting products. Hydrogen and grain surrounding the occurrence of synergies resulting in excessive wear in the hot-rolled copper cracks. This article includes: glue, thiourea these two main organic additives on the cathode overvoltage and cathodic copper in the hydrogen content is proportional to the cell cathode overvoltage. And proposed: In actual production, the best over-voltage range -30mV below this range, the cathode copper impurities hydrogen content can be maintained at 1
