Description

technical field [0001] An experimental device for researching hydrogen absorption characteristics on the surface of an aluminum melt is used to determine the relationship between the ambient humidity and the amount of hydrogen absorbed by the melt during metal aluminum smelting. Background technique [0002] During the forming process of aluminum, it is easy to form defects such as pores and pinholes. This is due to the reaction between the aluminum melt and the water vapor in the air to generate hydrogen and be absorbed by the aluminum melt. Determining the quantitative relationship between the hydrogen absorption of aluminum melt and the humidity of the atmosphere is an important research topic for researchers. But still do not have corresponding at present, especially this type of experimental device for laboratory research. [0003] The Chinese patent "Internal Combustion Engine Air Inlet Humidity Regulating Device" (Patent No.: ZL200420116599.7) applied by Zhang Sipu u...
