Background

Casting is a method in which liquid metal is cast into a casting cavity that conforms to the shape of a part, and after it is cooled and solidified, a part or a blank is obtained. Most of the cast materials are metals which are originally in a solid state but are heated to a liquid state. In the casting of nodular cast iron, molten metal is required to be poured into a nodulizing ladle for nodulizing reaction, and finally casting is carried out after the nodulizing reaction is finished. However, in the process of pouring the ladle into the spheroidizing ladle, the temperature is reduced quickly in the process of ladle due to the higher temperature of the molten metal and is easy to oxidize, and the quality of the casting is influenced finally; meanwhile, in order to improve the quality of the casting, casting is generally completed within ten minutes after the spheroidization reaction, but the complicated process does not necessarily ensure that casting is completed within ten minutes after the spheroidization reaction in order to ensure the safety of personnel.

See granted patent No. CN201320673469.2 for "a movable ladle" which requires a worker to pour molten metal from a ladle by turning a hand wheel. But the ladle itself is of very high quality and the entire ladle of hot molten metal is also hazardous and inefficient.

Therefore, a casting furnace which not only can improve the quality of castings, but also is convenient and safe in operation process is particularly needed.
