Aluminium alloy smelting device

Abstract

The invention provides an aluminium alloy smelting device which comprises a smelting mechanism, a stirring mechanism, a conveying mechanism and a temperature control mechanism, wherein the smelting mechanism comprises a resistance type crucible smelting furnace, a furnace lid located above the smelting furnace, a first hydraulic cylinder connected with the furnace lid and a graphite crucible located in the smelting furnace; aluminum liquid is contained in the crucible; the stirring mechanism comprises a graphite bell jar; the top end of the graphite bell jar is connected with a motor through a connector and a transmission system which are located on a mounting plate; a second hydraulic cylinder is arranged on the mounting plate; the conveying mechanism comprises an air compressor and a conveying pipe; a feeding tank is mounted between the air compressor and the conveying pipe; the tail end of the conveying pipe is connected with a through hole in the graphite bell jar; the temperature control mechanism comprises an internal thermocouple and an external thermocouple; the internal thermocouple penetrates through the resistance type crucible smelting furnace and is communicated with the interior of the furnace; and the external thermocouple passes through the interior of the graphite bell jar and is connected with the aluminum liquid. Through the design and use of the structure, the stability of ingot quality can be guaranteed, so that the stability and reliability of later-period experiment data are guaranteed.

Description

technical field [0001] The invention relates to the field of metal smelting, in particular to an aluminum alloy smelting device. Background technique [0002] When the laboratory uses an ordinary crucible resistance furnace to smelt aluminum alloy, it is difficult to simulate the industrial production site, and many problems will be encountered during the experiment: 1. The ordinary crucible resistance furnace only has a thermocouple to measure the furnace temperature, which is not easy to control The temperature of the alloy liquid; 2. Ordinary crucible resistance furnaces do not have stirring devices, and manual stirring or other mixers are required, which is difficult to ensure that alloy elements are evenly distributed in the melt and ensure the quality of the melt; 3. Ordinary crucible resistance furnaces are not equipped Feeding device, when adding metals or powdered refining agents and sodium salt modifiers with a density lighter than that of molten aluminum into molt...
