Experimental production exploration of SiC side carbon blocks for aluminum cathodes
This article introduces the preliminary exploration process of feasibility experiments on the production of cathode SiC side carbon blocks for aluminum in our company by China Aluminum Guizhou Branch and Guizhou Aluminum Plant Huayang Carbon Plant,after developing new formulas and optimizing and improving the kneading process.The experimental results show that the volume density,compressive strength,and resistivity of silicon carbide side blocks reach an average of 1.65g/m3,33MPa,and 52,respectively μΩ.m,compared to conventional side blocks,there is a significant improvement.Therefore,when used on the electrolytic cell,it is beneficial to improve the side heat dissipation of the electrolytic cell and reduce the horizontal current of the electrolytic cell,and can reduce the absorption and expansion of silicon carbide side blocks when used on the electrolytic cell.
