    摘要： A cylindrical gas turbine combustor, burning injected fuel and guiding the combustion gas to turbine nozzles 14, is characterized in that a cylindrical portion of the combustor such as combustor liner 15, a transition piece 16, exposed to the combustion gas is made of austenitic Fe base casting alloy, Ni base casting alloy or Co base casting alloy. The gas turbine combustor which has excellent thermal fatigue and long life is obtained. A gas turbine employs the combustor.

    摘要： Asemi-annular mold space is defened by a pair of rotating wheels (10,12) and an endless belt (18) passing aroung cur- cumferential surfaces of the wheels (10,12). Molten metal (40) is injected into the mold space upwardly so that it is statically poured into the mold. The circumferential edges of opposing surfaces ofthe wheels (10,12) have surfaces (14,16) inclined in such a manner that the width of the mold space becomes narrower in the direction toward the axis of the wheels (10,12). The molten metal (40) is continuously solidified by the belt (18) and the inclined surfaces (14,16) and withdrawn horizon- tallyfrom the mold space as a cast strip (48) while unsolidified molten metal remains within the upper portion of the solid shell.

    摘要： In manufacture of composite steel ingot, a consumed electrode 11 is inserted into an empty space concentric with the ingot 10, and electroslag remelting is effected under a slag bath 16 and the molten metal solidifies. Current is taken out through a plurality of collecting electrodes 12 electrically connected to the ingot. To obtain improvement in the uniformity of depth of fusion of the ingot, the flow path of the electric current passing from the consumed electrode to the collecting electrodes is moved in the circumferential direction of the ingot during the electroslag remelting, e.g. by rotating either or both of the ingot and the collecting electrodes. Further improvement may be achieved by varying the speed of movement of this flow path as the slag bath ascends the ingot.
