Abstract
The utility model provides a novel feeding device, which comprises two bell jars disposed from the top to the bottom. The external larger bell jar is used for isolating external air or inputting protective gas to ensure the stability and safety of the melting process. Applying the feeding device in such a structure, various kinds of shortcomings of the bell jar device in the prior art can be overcome, the burning loss during feeding in the process of aluminum alloy melting is greatly reduced, utilization rate of the alloy elements is enhanced, and quality of the final products is improved.
Description
Technical field
The feeding device that the utility model adopts when relating to a kind of melting is specifically related to a kind of novel feeding device of smelting aluminium alloy.
Background technology
Aluminium alloy is to be the alloy general name of base with aluminium, main alloy element has copper, silicon, magnesium, zinc, manganese, less important alloying element has nickel, iron, titanium, chromium, lithium etc., and aluminium alloy density is low, but strength ratio is higher, near or surpass the high-quality steel, plasticity is good, can be processed into various section bars, has good electric conductivity, thermal conductivity and corrosion stability, industrial being extensive use of, use amount is only second to steel.
In the aluminium alloy smelting process, usually need to add in the alloy that some are volatile, the metallic element of easy scaling loss such as lithium etc., as alloying component or to the alloy processing of going bad, cause final aluminium alloy quality can't reach standard and situations such as oxidation very easily take place in fusion process these elements.In order to reduce the scaling loss of these metallic elements, the single bell-jar feeding device of normal employing in the production is pressed into the smelting furnace bottom to the material that will add to play the effect of secluding air.Employing vacuum melting is also arranged, reduce oxidation and scaling loss.Yet reinforced self volatilization and the scaling loss protection to some elements such as Mg, Li etc. of single bell-jar is less, can't play effective protective effect; Though and the vacuum melting effect is fine, have high input, production efficiency is low.Therefore, solving the loss of the metal of volatile in the aluminium alloy smelting process, easy scaling loss, is one of problem that must solve now
Summary of the invention
Many weak points at the prior art existence; the utility model provides a kind of novel feeding device; this device is provided with two bell jars from top to bottom; protect the stable and safety of fusion process by isolated outside air of the effect of the big bell jar in outside or input protection gas; adopt the feeding device of this structure, overcome all drawbacks of existing single bell jar device, greatly reduce the scaling loss of aluminium alloy smelting when reinforced; improve the utilization rate of alloying element, improved the quality of final products.
The concrete technical scheme that the utility model adopted is: a kind of novel feeding device of smelting aluminium alloy, it is provided with two bell jars from top to bottom, the bell jar diameter of bottom is less than top bell jar diameter, the bottom bell jar is fixedlyed connected with depression bar, the top bell jar be provided with cooperate with depression bar and depression bar along its hole that moves up and down.
During general the design, can control the crucible external diameter of the diameter of top bell jar greater than smelting aluminium alloy, adopt such design, the bell jar that at first can adopt the bottom is volatile with in the aluminium alloy other, easily the scaling loss raw material is pressed into the smelting furnace bottom to play the effect of secluding air melting, simultaneously since the diameter of top bell jar greater than the crucible external diameter of smelting aluminium alloy, make it can be complete whole crucible is covered, thereby further the space in the whole crucible is hedged off from the outer world, guaranteed anaerobic or the approximate oxygen free condition in the fusion process, greatly reduced volatile, the easily loss of the metal of scaling loss; In order to cooperate the use of bottom bell jar, the bottom bell jar is provided with depression bar, and this depression bar moves up and down by the hole on the bell jar of top, thereby realize real-time control for the smelting metal of crucible bottom, can also guarantee simultaneously that the air pressure in the whole crucible maintains stable status, for safety in production provides powerful guarantee.
In order to reach the effect of better secluding air, the air admission hole of at least one can be set on the bell jar of top, can be transported to the protective gas in the melting in the melting kettle endlessly by this air admission hole, thereby, more help improving the effect of melting and the quality of final products at the inner oxygen free condition of making of crucible; The diameter of bottom bell jar is less than the crucible external diameter of smelting aluminium alloy, can guarantee bell jar freely moving up and down in crucible, some through holes that are provided with on the bell jar of bottom are convenient to mix with aluminum alloy melt behind the material melting, before also being convenient to add material are fixed on below the bell jar of bottom.
In sum; adopt the feeding device of this structure; protect the stable and safety of fusion process simultaneously by isolated outside air of the effect of the big bell jar in outside or input protection gas; all drawbacks of existing single bell jar device have been overcome; greatly reduce the scaling loss of aluminium alloy smelting when reinforced; improve the utilization rate of alloying element, improved the quality of final products.
