Description

Aluminum electrolysis cell cathode carbon block clamp Technical Field The invention relates to the technical field of cathode carbon blocks, in particular to a clamp for a cathode carbon block of an aluminum electrolysis cell. Background In the aluminum electrolysis industry, a cathode carbon block with a certain specification is needed to be adopted in a preparation anode electrolytic tank adopted in an electrolytic aluminum factory, in the manufacturing process of the cathode carbon block, a clamp is needed to hoist the cathode carbon block due to different production procedure requirements, the carbon block is needed to be bound before the hoisting, and then the carbon block is hoisted by a hoisting claw.
