Abstract

The invention discloses a metal smelting furnace, and belongs to the field of metal smelting devices. According to an existing smelting and thermal insulating system, when metal liquid in a soup taking chamber is oversupplied, the temperature is prone to being reduced to be below the temperature required by casting. A refining chamber is arranged on at least one side of a thermal insulating furnace, a soup taking chamber is arranged on one side of the refining chamber, the bottom of the refining chamber is communicated with the bottom of the thermal insulating furnace through a channel, an impeller is arranged at the bottom of the refining chamber, a channel port of the channel is located below the impeller, an air conveying channel capable of conveying air to the part below a liquid surface is arranged in the refining chamber, the impeller rotates to scatter and refine metal liquid entering the refining chamber and provides force for lifting metal liquid upwards so that the metal liquid surface in the refining chamber can be higher than the metal liquid surface in the thermal insulating furnace, a liquid conveying through hole is formed in a partition wall between the soup taking chamber and a cavity of the refining chamber so that the soup taking chamber and the refining chamber can be communicated with each other, and a return through hole capable of returning and conveying metal liquid in the soup taking chamber to the thermal insulating furnace is formed in a partition wall between the soup taking chamber and a cavity of the thermal insulating furnace.

Description

technical field [0001] The invention belongs to a metal smelting device, in particular to a metal smelting furnace. Background technique [0002] In the field of metal casting, metal smelting is one of the key processes in casting production, which generally refers to melting solid metal into liquid with a heating furnace and tempering. The existing metal smelting system mainly includes a heat preservation melting furnace, a soup taking room and a refining room arranged on the side of the heat keeping melting furnace. The bottom of the heat preservation melting furnace is connected, and an impeller is set in the refining chamber. Through the rotation of the impeller, the molten metal entering the refining chamber is broken up and refined, and the molten metal is provided with an upward lift. The liquid is input into the soup taking room for standby, and the liquid level in the refining room and the soup taking room is roughly equal. In the refining room, a gas pipeline is...
