DISMANTLING THE LINING OF AN ELECTROLYZER CATHODE UNIT FOR ALUMINUM PRODUCTION USING HYDRAULIC PRESS EQUIPMENT AND DIAMOND CUTTING TOOLS

摘要

Technology is considered for dismantling the lining of a aluminum electrolyzer cathode unit for major over-haul directly within the electrolyzer building. In order to accelerate breakdown of the lining and reduce the ef-fect of impact and vibration loads during dismantling on the neighbourhood during repair of the electrolyzer, cathode dismantling is performed using hydraulic press equipment for impact-free breaking of materials using diamond tools for cutting and boring. Acceleration of dismantling is achieved as a result of the use of hydrau-lic equipment making it possible to create within the electrolyzer cathode lining material local nonuniform pressure distribution providing crack formation breaking the integrity of the lining.
