Abstract
1,268,619. Self-baking electrodes. MONTECATINI EDISON S.p.A. 24 Aug., 1970 [22 Aug., 1969], No. 40607/70. Heading H5H. A method of continuously measuring the degree of baking of a self-baking electrode includes the step of measuring the voltage drop between a metal member 8, passing through both the unbaked, electrode-forming paste 2 and the baked mass 5 of carbon, and the peripheral metallic shell 1. The metal bar 8 is consumed with the carbon mass during operation of a furnace utilizing the electrode, e.g. a submerged arc furnace for producing metals or alloys. A three-phase furnace for producing calcium carbide is referred to. Contacts 6 and conductors 7 connect the electrode to an external circuit. Insulated and shielded conductors 10, 11 connect member 8 and shell 1 to a double moving element recording resistometer 9, for measuring the voltage drop, and conductors 12, 13, convey a measurement of the electrode current supplied, so that the resistometer 9 records the ratio C between these two quantities, as an indication of baking. Member 8 is connected via insulating tension rods to the reinforcing structure of the electrode (not shown). A detailed example is given, specifying dimensions and operating conditions.
