When using crucible for melting of aluminum alloys, put cold material, once all the soup is finished melting furnace melt, scoop out the melt soup, at the appropriate time to make up for melting and thermal insulation of cold material, also accepted in focus after melting furnace melt melt soup, insulation, and other ways. Single furnace melting and melted insulation, suitable for the aluminium alloy castings. Smell in H2 uptake of aluminum alloy casting and oxide mixed with, need to use a large spoon to scoop out quietly melted soup, using the standard crucible of the mouth larger or bowl-shaped crucible. Manner acceptable to melt soup for thermal insulation, generally more common in the die-cast, using a large spoon, so use a large bowl-shaped crucible.
Tilting crucible furnace, generally used in the concentrated meltdown. In addition to cutting waste recycling melting, also using #1500 graphite crucibles.
In the past, die-cast aluminium alloy melting most of them use a cast iron pan, die-casting casting more than 80% are high quality requirements for vehicle spare parts, gradually replaced by graphite crucible.
