Abstract
This invention relates to a method of producing carbonaceous blocks, and more particularly to a method of manufacturing anodes for the electrolytic reduction of aluminum, consisting of coating said blocks with an antioxidizer protective powder and calcining them while being passed through a tunnel type furnace in an oxidizing atmosphere in conformity with thermal conditions whereby, as said blocks reach a temperature of 200.degree.-600.degree. C. at which they release volatile organic substances, said oxidizing atmosphere has a temperature of at least 550.degree. C.; thus, complete combustion of the volatile substances is accomplished in said furnace to yield gases which are free of said volatile organic substances, and wherein said blocks later attain a final baking temperature of up to about 1,200.degree. C.
