Description

technical field [0001] The invention relates to the field of industrial manufacturing, and in particular provides a casting method for manufacturing high-conductivity and heat-resistant electrode beam parts. It specifically relates to the manufacture of a cathode plate electrode beam component commonly used in the field of electrolytic zinc metallurgy by adopting casting technology. The component has good mechanical properties on the basis of excellent electrical conductivity and heat resistance. Background technique [0002] The electrode beam part is a key part commonly used in the electrolytic zinc industry. This part is connected with the cathode electrode plate and plays a role in supporting the cathode electrode plate. The working environment of the electrode beam parts is poor. Not only does it work in a high-temperature environment for a long time, but it also bears the weight of the cathode electrode plate, which puts forward high requirements on its heat resistance...
