Molten metal processing equipment, molten metal processing method, and molten metal conveying line using the same

Abstract

Provided is a molten metal treatment facility wherein the facility can be made compact by attaining space saving of the molten metal transport line, and the cycle time can be shortened while reducing the cost by shortening the time required for transporting the molten metal to the next process (e.g. pouring process). A molten metal treatment facility which carries out spherification of graphite by using a graphite spherification agent in the molten metal in a ladle with a lid, opens and closes the lid and removes the slag of molten metal in the ladle where spherification of graphite is carried out comprises a ladle transporting / supporting device which transports the ladle to a predetermined position and supports the ladle at the time of tilting, a graphite spherification device which carries out spherification of graphite by charging an inoculation agent into the molten metal in the ladle which is transported to the predetermined position, a lid open / close device which opens and closes the lid by elevating and lowering the lid of the ladle, and a ladle tilting device which tilts the ladle transporting / supporting device along with the ladle.

Description

technical field [0001] The present invention relates to an apparatus for graphite spheroidization and slag removal (slag) on ​​a molten metal conveying line in a foundry and a method for graphite spheroidization and slag removal using the apparatus. Background technique [0002] Conventionally, in foundries that manufacture castings, there is an automatic pouring device that receives molten metal from a melting facility into a ladle by a receiving trolley, transports the ladle without lifting it by a crane, etc., and pours and melts it into a mold. Metal (see Patent Document 1). In this device, when the material of the cast product is spherical graphite cast iron (FCD), graphite spheroidization is carried out by putting a graphite spheroidizer into the ladle during the process from receiving the molten metal to pouring the molten metal. treatment. Next, the molten metal is conveyed to the slag extraction position by another ladle, and after further slag extraction is perfo...

AI Technical Summary

Problems solved by technology

[0004] However, in the apparatus described in Patent Document 1, since the graphite spheroidization treatment place and the slag removal place are separated, there are problems of an increase in the overall size of the facility, an increase in cost, and an overall enlargement of the route for conveying the molten metal.

In addition, since the molten metal is transported to the slag extraction position after the graphite spheroidization process, there is another problem that the cycle time for pouring the molten metal into the mold is prolonged during this period of time.
