Hello everyone, I am the youngest girl in the factory.
In the casting process, the purpose of smelting has three points:
(one) In order to obtain an alloy with a uniform chemical composition
and meet the requirements:
the structure and properties of the alloy material,
in addition to the influence of the process conditions,
must first be guaranteed by the chemical composition.
If a certain component or impurity exceeds the standard,
it will be treated as chemical component waste,
resulting in great losses.
(two) Alloy melts with high purity are obtained by refining:
the electrolytic aluminum liquid supplied by the smelter
or the scraps returned to the furnace often contain impurities,
gases, and oxidized slag inclusions.
Refining to remove these impurities,
gases, oxides, etc., to improve the purity of molten metal.
(three) In addition to the above purpose,
the casting workshop also has the task of compounding the recycled waste:
these recycled wastes are often mixed due to lax management,
the composition is unclear,
or they are contaminated with oil and other sundries,
or the debris cannot Directly used in the production of finished alloys,
the smelting process must be used to obtain the exact chemical composition
and cast into ingots suitable for re-furnace.
