Smelting furnace for preparing aluminum alloy containing micro holes

Abstract

The invention discloses a smelting furnace for preparing aluminum alloy containing micro holes. The smelting furnace comprises a shell, a heating assembly, an inner sleeve, a driving assembly, a stirring blade, a furnace lid, a communication pipe, an exhaust pump and a mixing box. A nitrogen injection port and a hydrogen injection port are arranged on the furnace lid, the nitrogen injection port and the hydrogen injection port are both communicated with a cavity formed by the inner sleeve and the furnace lid, one end of the communication pipe is connected with a drive shaft of the driving assembly, the other end of the communication pipe penetrates through the furnace lid and stretches into the cavity, an outlet is formed in the other end of the communication pipe, the stirring blade is arranged in the cavity and installed on the communication pipe, the communication pipe is sleeved with a mixing box, a raw material inlet is formed in the mixing box, and a communication hole is formedin the wall of the communication pipe. An aluminum alloy finished product manufactured by a hydrogen loading agent through the smelting furnace has abundant micro bubbles, the finished product can have the air-permeable or oil-penetrating or water-permeable function due to the micro bubbles, and no contamination is caused to the environment in the preparation process.

Description

technical field [0001] The invention relates to the field of melting furnaces, in particular to a melting furnace for preparing micropore-containing aluminum alloys. Background technique [0002] Aluminum alloy smelting furnace is a high-efficiency and energy-saving aluminum melting furnace developed according to the aluminum smelting process. It is mainly used for melting and heat preservation of aluminum ingots, and it can well meet the aluminum smelting process. [0003] The aluminum alloy produced by the existing aluminum alloy smelting furnace does not contain micropores. In some fields, it is necessary to use a metal plate containing micropores, and use the micropores on the metal plate to achieve the purpose of air permeability, oil permeability or water permeability. At present, the processing method for this type of metal plate with micropores is to corrode with chemical reagents. The metal plate produces micropores on the metal plate, and the method pollutes the e...

Problems solved by technology

In some fields, it is necessary to use a metal plate containing micropores, and use the micropores on the metal plate to achieve the purpose of air permeability, oil permeability or water permeability. At present, the processing method for this type of metal plate with micropores is to corrode with chemical reagents. The metal plate produces micropores on the metal plate. This method pollutes the environment and is not conducive to the large-scale production of aluminum alloys containing micropores.
