Example repeats), it is as a result as follows, due to the fluctuation of price, when the quality of aluminium ingot accounts for electrolytic aluminium liquid gross mass 28%~33%, electricity
The overheat condition neutralizing for solving molten aluminum is more quick, and heat waste and oxidization condition are low, and the heating power consumption of smelting furnace is also relatively fewer, throw
The refining agent dose entered is moderate, and non-spontaneous property nucleus quantity is higher, and crystal grain refinement agent dose is moderate；Aluminum plate foundation strip quality guarantee
While, production cost is also greatly lowered.
Meanwhile automatic siphon equipment, bipolar plate filter, the online depassing unit of Hycast I-60SIR and liquid level prison
Device is controlled, is respectively set about from material feeding, slagging-off, degasification and casting process, existing two-man ladle of automatic siphon equipment replacement is
Material feeding mode, it is characterized in that, 1, be effectively contained in during electrolytic aluminium liquid there are oxidization condition, electrolytic aluminium liquid vacuum feeding,
Fast and safely；2, directly prevent the collision of electrolytic aluminium liquid and generate torrent, avoid being involved in for large quantity of air.Secondly, just filtering is imitated
For rate, the filtering and removing slag effect of bipolar plate filter is apparently higher than floamed ceramics filtrating piece.In addition, Hycast I-60SIR
Its more existing online depassing unit of online depassing unit is compared, and feature is, equips internal moment holding sealing, and when degasification,
Melt will not generate logistics, in degassing procedure, will not be involved in air, generate oxidation impurities.And in liquid level monitoring device, displacement passes
Sensor issues stabilized light source, is changed according to the hot spot on molten aluminum liquid level, calculates molten aluminum liquid level, PLC is returned according to displacement sensor
The liquid level changing value returned, control servo motor rotation, drives adjustable plate rotation, adjusts the feed liquor area of liquid feeding end, and then adjust
Molten aluminum liquid level, to ensure that molten aluminum liquid level is constant in certain accuracy rating, it is ensured that the casting efficiency of aluminum plate foundation band.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
In the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by anyone skilled in the art,
It should be covered by the scope of protection of the present invention.Therefore, protection scope of the present invention should be with the protection scope of claims
Subject to.
