Aluminum liquid backwater circulating device of smelting heat-holding furnace

Abstract

An aluminum liquid backwater circulating device of a smelting heat-holding furnace comprises a heat holding chamber, a deaerating chamber, a static chamber and a using chamber which are communicated with each other and further comprises a lifting device. The lifting device comprises a backwater chamber, a motor and a graphite rod, and the backwater chamber is communicated with the using chamber through a first pipeline. The backwater chamber is communicated with the heat holding chamber through a second pipeline which is slantly arranged from top to bottom, the upper end of the second pipeline is connected with a water outlet hole of the backwater chamber, the lower end of the second pipeline is connected with a water inlet hole of the heat holding chamber, and the water outlet hole of the backwater chamber and the water inlet hole of the heat holding chamber are respectively located above the surface of aluminum liquid in corresponding chamber. The tail end of the graphite rod is arranged in the backwater chamber, and the upper end of the graphite rod is connected with an output shaft of the motor. The lifting device is added, temperature difference between the using chamber and the heat holding chamber is shortened by quickening flow of the aluminum liquid. Under the condition of unchanging the temperature of the using chamber, the temperature of the heat holding chamber is lowered, service life of the heat holding chamber is prolonged, aluminum consumption is reduced, and fuel is saved.

Description

(1) Technical field [0001] The invention belongs to an aluminum soup return water circulation device of a smelting and holding furnace. (2) Background technology [0002] The melting and holding furnace is a kind of equipment that melts aluminum ingots into aluminum soup and performs conditioning, degassing and other treatments on the aluminum soup. The aluminum soup in the existing smelting and holding furnace flows through the degassing chamber, the static chamber in sequence from the holding chamber, and finally flows to the use chamber for standby. This device requires that when the temperature of the aluminum soup in the heat preservation chamber is 60°C-80°C higher than the temperature of the aluminum soup in the use chamber, the aluminum soup in the use chamber can meet the requirements for use. Due to the high temperature requirements of the heat preservation chamber, the short service life of the heat preservation chamber, large aluminum consumption and large fuel ...

AI Technical Summary

Problems solved by technology

Due to the high temperature requirements of the insulation room, the service life of the insulation room is short, the aluminum consumption is large, and the fuel waste is large.
