METHOD FOR DETERMINATION OF MIDDLE BOTTOM TEMPERATURE AT BURNING OF ALUMINIUM ELECTROLYTIC CELLS

摘要

A method for determination of middle bottom temperature at burning of aluminium electrolytic cells, at which size of bottom and its starting temperature are determined before starting of burning process, thermal-physical properties of bottom blocks and current strength of a series (at burning of electrolytic cells by Joule heat) or combustion heat of fuel (at fire burning of electrolytic cells) are determined and amount of supplied heat is determined in burning process. A middle-volume temperature of bottom is determined for any time moment of burning from the equation:.
