Special smelting furnace

Abstract

The invention discloses a special smelting furnace. The special smelting furnace comprises a shell, a heating assembly, a crucible, a driving assembly, a stirring blade, a furnace cover, an evaporatorand a water inlet pipe. A transmission shaft of the driving assembly penetrates through the furnace cover, and the stirring blade is located in the crucible and mounted on the transmission shaft of the driving assembly. The evaporator comprises an evaporator shell, an evaporator copper crucible and an evaporator cover body, the evaporator copper crucible is arranged in the evaporator shell in a sleeving mode, the evaporator shell is fixed to the inner wall of the crucible, water vapor through holes are formed in the evaporator cover body, and the evaporator cover body is mounted on the evaporator shell. The water inlet pipe comprises a ceramic pipe, a flexible pipe and a metal water pipe. Aluminum alloy finished products prepared by the special smelting furnace are rich in a plurality oftiny holes, the tiny holes enable the aluminum alloy finished products to be provided with ventilated, oil-through and permeable functions, pollution to the environment is not caused in the preparation process, and the aluminum alloy finished products can be produced on a large scale.

Description

technical field [0001] The invention relates to the field of melting furnaces, in particular to a special melting furnace. 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 environment and is unfavorable for large-sca...

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.
