METHOD FOR BLOWING GAS DUCTS OF ALUMINUM CELLS WITH SYSTEM FOR AUTOMATIC SUPPLY OF ALUMINA

摘要

aluminum production, possibly designs of cells having system for automatic supply of alumina. SUBSTANCE: method comprises periodical supply of compressed air through branch pipes inclined by acute angle relative to lengthwise axis of pipeline of gas duct in several points along direction of gas suction; impulse feed of compressed air at using waste compressed air from pneumatic cylinders of punches of systems for automatic supply of alumina. EFFECT: enhanced efficiency for keeping gas duct in working state, lowered acoustic noise in shop. 3 cl, 1 dwg
