PURPOSE:To omit a drying process and save energy in processes for producing firebricks, especially unburned firebricks. CONSTITUTION:A refractory raw material comprising alumina or magnesium oxide is mixed with >=2wt.% of a raw material containing conductive particles and a binder, followed by molding the mixture. The molded product is brought into contact with two electrodes, and an electric current is directly applied to the electrodes to thermally cure and/or dry the molded product, thereby permitting to reduce the cost of energy into approximately a half thereof and to especially perfectly automatize the production processes of firebricks in the case of the firebricks or unburned firebricks. |
