Effect of Additive Silicon Powder on Physical Property of Cold Ramming Paste for Aluminum Electrolysis

Abstract:

The cold ramming paste for aluminum electrolysis has been studied using electrically calcined anthracite as aggregate, medium temperature pitch and anthracene oil as binder, metallic silicon powder as additive in the paper. The effects of addition of silicon on volume density, compressive strength, electrical resistivity, shrinkage value have been studied. The results show that: volume density, compressive strength of cold ramming paste are increased firstly and then decreased with the addition of silicon increasing, and electrical resistivity, shrinkage value are decreased firstly and then increased with the addition of silicon increasing. So when the addition of silicon is 3%, the physical properties are preferable.
