Abstract
PURPOSE: To prevent the sticking of adjacent pieces of raw carbon molded articles in a firing furnace, and to make the inner tissue of the article homogeneous, in the firing of two or more raw carbon molded articles in a firing furnace, by providing the surface of the article contacting with the adjacent article with a groove having specific dimensions.
CONSTITUTION: Raw materials of aggregates such as pitch coke, petroleum coke, etc. are mixed with a carbonaceous binder such as pitch, and the mixture is formed to obtain a raw carbon molded article. Two or more articles thus prepared are placed horizontally in a firing furnace contacting a surface of an article with that of the adjacent article, and fired. In this case, at least one of the surfaces 5 which comes to contact with the surface of the adjacent article, is provided with at least one vertical groove. The depth of the groove is ≥2% of the thickness H of the molded article 1, and the groove reduces the contacting area of the surface 5 by ≥10%.
