(II) Control of hydrogen content in aluminum alloy smelting
Hydrogen absorption in aluminum alloy smelting is a major problem
that causes pinholes in aluminum alloy castings to reduce pinhole
properties and mechanical properties. Therefore, various measures
must be taken to strictly control the content of hydrogen and other
gases. The measures for controlling the hydrogen content in the
smelting process are shown in Table 5-84. The rapid determination
method of hydrogen content is shown in Table 5-85.
Control key points
Detecting one side flying E
Before charging the furnace, it is necessary to strictly remove the
rust and oil on the surface of the charge, and preheat it to the
Before adding the charge, the oven should be used to remove the
moisture of the furnace (the vortex) to avoid moisture and
Furnace gas hydrocarbons are in contact with the charge. For die
castings that require very tight pinholes, they can be used for
furnace gas analysis or for measuring wet B of air.
Inert gas or cover agent to protect the liquid surface, prevent
inhalation, and use enhanced degassing
Refining agent refining alloy liquid
The tool should be fully preheated to remove moisture before
contact with the alloy solution.
Smelting process Controls the melting temperature and time,
prevents the alloy liquid from overheating, and selects and makes
rapid hydrogen measurement in front of the furnace.
With the refining agent and its amount and refining time, the
refining agent must be fully dried before use.
Smelting operation As far as possible, no damage or less damage to
the protective film on the surface of the alloy and prevention of
Human alloy liquid
Casting operation Reduce the stirring of the alloy liquid as much
as possible, prevent the oxide roll from being in the alloy liquid,
strictly check the process and measure the hydrogen before the
