Description
Technical field
A kind of alloy melting stove relates to a kind of smelting furnace that is used for the alloy of magnesium-rare earth, magnesium-lithium alloy and easy oxidation metal.
Background technology
In the alloy melting process, avoid alloy, particularly the scaling loss oxidation of chemical property active metal is an important link.
With magnesium is example, and magnesium alloy has excellent performance, is called as " green material of 21st century ", is widely used.But in fusion process,, cause impurity to increase, influence quality product because liquation oxidation, suction hydrogen and flux and operational tool pollute.And because chemical property is very active, in the above temperature of fusing point, the active metal of chemical property can with airborne oxygen generation vigorous reaction, in fusion process, the protection melt, to reduce oxidation be one of crucial technology.Particularly, be not suitable for melting in vacuum oven because the vapour pressure of magnesium is big, volatile.In addition, because the thermal capacitance of magnesium is little, in casting process, long distance is carried, and heat is scattered and disappeared, and liquation is set in the pipeline, causes the production difficulty big.
At present, in the fusion process of metal, main flux protection and the gas protected mode of adopting.In the fusion process of magnesium, well formula crucible oven method is arranged, owing to be to open wide melting, the volatilization of muriate flux, the melt oxidation scaling loss causes casting yield low, and the flux usage quantity is big, and operating environment is poor, uses flux also to be unfavorable for constant product quality in a large number.Wherein, contain sulfur hexafluoride in the shielding gas, serious to depletion of the ozone layer, abroad ban use of.For highly active alloys such as magnesium-lithium, magnesium-rare earths, muriate flux commonly used can not be used, its special-purpose flux cost height, and effect is not very good.During cast, use electromagnetic pump to extract out, or scoop out with spoon.The former can produce stirring in casting process, influence quality product, and latter's melt stirs less, but the working strength height.
The magnesium alloy smelting method (application number 00131679.6) of Mitsui metal mining industry Co., Ltd. invention adopts the smelting furnace more than two, separates impurity such as flux in the alloy, oxide compound effectively, is applicable to large-scale alloy melting.
When the small-scale melting, the close crucible that adopts a Room is to prevent melt oxidation incendiary good method, but the sealing under the high temperature be difficult to realize, and the stirring of melt in the airtight crucible, and the derivation difficulty of liquation is bigger.The application number of Shanghai Communications University is 02136199.1 Mg alloy smelting furnace patent documentation, disclose a kind of from crucible bottom discharging melting equipment, but it is not suitable for common well formula crucible oven, and adopts swiveling jetting device to stir the sealed structure more complicated.A kind of tilting type Mg alloy smelting furnace of people such as the Li Peijie of Tsing-Hua University invention burns dispensing device (application number 02256766.6), can reduce the magnesium liquid oxidation, but complex structure needs pit furnace commonly used is done bigger change.The melting of metal crucible (application number 002395460) of Xia Chengliang invention relates to a kind of crucible that holds and melt magnesium alloy, can avoid using a large amount of flux, but not relate to the take-up gear of molten metal.Utility model---the pressure-flow-type high-purity magnesium and the magnesium alloy smelting crucible (application number 012529834) of Zheng Jingchun invention, in casting process, can not produce eddy current, improve the quality of products greatly, but its complex structure does not relate to the crucible tightness system, gate spool be the U type and elbow more, be unfavorable for flowing of liquation, easily stop up.
Summary of the invention
The objective of the invention is the deficiency that exists at above-mentioned prior art, provide a kind of and can effectively improve melting efficiency, reduce material loss, reduce environmental pollution, improve the quality of products, simplify operating process, improve the magnesium alloy smelting equipment of Working environment.
The purpose of this utility model is achieved through the following technical solutions.
A kind of alloy melting stove is characterized in that its structure composition comprises:
Smelting furnace body of heater---this body of heater is a upper end open tubular crucible crucible body structure;
Body of heater top cover-this top cover be one with smelting furnace body of heater crucible body top along the slab structure that cooperates the connection of lid dress flange; On the furnace roof top board, be provided with inlet pipe, vapor pipe and the tensimeter mouth of pipe;
