NEUI铝电解槽阴极铝钢直焊技术开发及应用

Development and application of NEUI aluminum electrolytic cell cathode aluminum steel direct welding technology

节能降耗不仅仅是企业的经济性问题,而且是关系到企业生存和发展的关键问题。针对铝电解槽传统焊接工艺技术压接接触压降和焊接焊口压降偏高的缺点,开发了NEUI铝电解槽阴极铝钢直焊焊接工艺技术,与传统焊接工艺技术相比,可将阴极钢棒与铝软带之间的压降降低约10mV左右,按照600kA电流计算,单槽年节约电量约为5.25×10^(4)kW·h。该技术已在多家铝厂得到推广应用。

Energy saving and consumption reduction is not only an economic issue of enterprises,but also a key issue related to the survival and development of enterprises.Aiming at the disadvantages of high pressure drop and high pressure drop of the welding joint of the traditional welding technology of aluminum electrolytic cell,the NEUI cathode aluminum steel direct welding technology was developed.Compared with the traditional welding technology,the pressure drop between the cathode steel rod and the aluminum soft strip could be reduced by about 10mV.The annual power saving of a single tank is about 5.25×10^(4)kW·h.This technology has been popularized and applied in many aluminum plants.
