Abstract

The invention provides a casting ladle and a device for preparing nodular cast iron. The casting ladle comprises a shell, a first fire-retarding portion and a second fire-retarding portion. The shellcomprises a ladle body and a ladle nozzle. The first fire-retarding portion is attached to the inner surface of the ladle body. The second fire-retarding portion is attached to the inner surface of the ladle nozzle. With the casting ladle and the device for preparing nodular cast iron, the problem that a fire-retarding portion of a ladle nozzle of an existing casting ladle is corroded badly, and the cost of replacement is high. Because the first fire-retarding portion is attached to the inner surface of the ladle body, and the second fire-retarding portion is attached to the inner surface of the ladle nozzle, the ladle body and the fire-retarding portion of the ladle nozzle are cast independently, the ladle nozzle can be replaced independently, operation is more convenient and quick, the production efficiency is improved, and the economic benefit is good.

Description

technical field [0001] The invention relates to the technical field of casting processes, in particular to a pouring ladle and a device for preparing ductile iron. Background technique [0002] Ductile iron is obtained by spheroidization and inoculation treatment to obtain spheroidal graphite, which reduces the splitting effect of graphite on the matrix, effectively improves the mechanical properties of cast iron, and obtains higher plasticity, toughness and strength. Ductile iron is a high-strength cast iron material developed in the 1950s. Its comprehensive performance is close to that of steel. Based on its excellent performance, it has been successfully used in some complex forces with relatively high strength, toughness and wear resistance requirements. high parts. People's requirements for the performance of ductile iron are getting higher and higher. A variety of spheroidizing treatment methods can be applied in the production of ductile iron. These spheroidizing tr...
