Cathode/Collector Bar Sealing


Seals around the steel collector bar, when positioned in the cathode block, retain cast iron during the pouring process. Cast iron leakage poses a hot metal hazard for operators and surrounding equipment. Additionally, cast iron leakage results in a scrap block and bar.
