    摘要： A grain coke is packed in a vertical furnace between a pair of opposite electrodes for passing current through the coke, thus heating the same to a temperature of above 1400.degree. C, preferably 1500.degree. C for more than 10 minutes. Coke is loaded into the furnace from an upper portion and heat treated coke is cooled and then discharged from the bottom. Inert or reducing gas may be introduced into the lower portion of the furnace and discharged from the upper portion thereby cooling heat treated coke and preheating loaded coke.

    摘要： A stave cooling device includes a double drawn steel tube cast-mounted in a castable metal main body, and the double tube includes an inner tube which serves as a passage for a coolant. The inner tube of the double tube contains 0.20 to 0.38% of equivalent carbon and an outer tube of the double tube contains 0.15 to 0.25% of equivalent carbon. The outer tube has on its outer surface an alumina coating of 0.08 to 0.25 mm thick, and the main body is formed by casting a spheroidal graphite cast iron. The double tube is cast-mounted in the main body such that the double tube and the main body are not welded together.
