摘要： A casting method of an active metal includes, in an induction melting furnace using a water-cooled crucible, tapping a molten metal into a mold from a tapping hole provided at a bottom of the water-cooled copper crucible to cast an ingot of the active metal. In conducting the casting under a casting condition in which the ingot has a diameter (D) of 10 mm or more and a ratio (H/D) of an ingot height H to the ingot diameter D of 1.5 or more and a weight of the molten metal tapped in the casting is 200 kg or less, a temperature of the molten metal in the casting is set to be higher than the melting point of the active metal and a casting velocity V (mm/sec) is controlled to satisfy V≤0.1H in relation with the ingot height H by adjusting an opening diameter of the tapping hole.

摘要： A method has been found for centrifugal casting engine cylinders. A mold is charged with molten aluminum alloy and particulate silicon monoxide having an average size of 0.01 mm to 0.04 mm. The mold is rotated at a velocity and period of time to distribute the particulate silicon monoxide on an inner cylinder surface. The mold is allowed to cool until the aluminum alloy solidifies. A casting is demolded characterized in a uniform inner cylinder surface of the particulate silicon monoxide in an amount of 25 volume % and thickness 1 to 5 millimeters. The engine cylinders are distinguished in resistance to wear. Cylinder liners show no appreciable wear for over 100,000 miles of use.
