The production of magnesium alloy, manufacturing must be through fusion process, and the melting of magnesium alloy is generally carried out in smelting furnace.Existing smelting furnace, its structure comprise the body of heater with thermal insulation layer, the crucible that places body of heater and heating unit, temperature measuring equipment, shielding gas input unit etc.During melting; the magnesium ingot of preheating is sent in the crucible from dog-house, carried out heat fused by heating unit, the shielding gas input unit feeds protective gas; the oxidation to prevent that magnesium alloy when fusing from contact with air, burning, temperature measuring equipment is used for monitoring, controlling Heating temperature.Magnesium alloy fused mass after the fusing is sent use by pump, pipeline again.
At above-mentioned fusion process, can produce some impurity, one deck scum silica frost that on bath surface, forms during as the magnesium alloy heat fused, and the metal generation oxidizing reaction of working as bath surface, when perhaps too greatly intermetallic being reacted owing to the Heating temperature deviation, the particulate state compound of generation is deposited on the slag that the stove bottom is produced.The existence of these impurity has influenced the purity of magnesium alloy fused mass, thereby influences the quality of magnesium alloy product.
The Mg alloy smelting furnace of said structure, its weak point is: (1) heating unit heats crucible integral body, and energy consumption is big, and is unfavorable for temperature control.(2) dog-house of crucible is vertical open type, and protective gas scatters and disappears in a large number when reinforced, causes waste.(3) method of regular descum of employing and slag not only can not be eliminated the influence of melting impurity to the magnesium alloy fused mass purity effectively, and reduce production efficiency, has increased production cost.
Summary of the invention
The purpose of this utility model is at the problems referred to above, and a kind of Mg alloy smelting furnace of novel texture is provided.
For this reason, the utility model adopts following technical scheme: Mg alloy smelting furnace, comprise crucible, and it is characterized in that: crucible has dog-house, material taking mouth, and dog-house, material taking mouth all are covered with removable cover; Crucible inside is separated into two working chambers of connection by dividing plate, and dog-house, material taking mouth are communicated with a working chamber respectively.
Described divider upright setting is separated into two working chambers that the bottom is communicated with crucible inside.
Described crucible has inclined bottom, and its inclination mode is as follows: crucible bottom has a down dip from material taking mouth one side direction dog-house one side direction.
Described dog-house is obliquely installed.
Described Mg alloy smelting furnace also comprises two heating units that respectively two working chambers heated.
Described Mg alloy smelting furnace also comprises two temperature measuring equipments that detect two working chamber's temperature respectively.
Described Mg alloy smelting furnace also comprises respectively two shielding gas input units to two working chamber's input protection gases.
The Mg alloy smelting furnace that the utility model provides is compared with the smelting furnace of traditional structure, has following characteristics:
(1) crucible inside is separated into two working chambers, feeds intake, gets material and be independent of each other, and can realize operate continuously, enhances productivity.(2) can by two heating units, temperature measuring equipment, control two working chamber's Heating temperatures separately neatly according to actual needs, avoid energy dissipation, make magnesium alloy fusing effect reach optimization.(3) dog-house is obliquely installed, and reduces protective gas and scatters and disappears, and reduces consuming.(4) two working chambers are separated by dividing plate and are communicated with by the bottom, make that the scum silica frost on the metallic surface, dog-house one side working chamber can not be floated in the material taking mouth one side working chamber.Simultaneously, because crucible bottom is to the dog-house lopsidedness, slag deposition is in the bottom, working chamber that is communicated with dog-house, thus guaranteed with working chamber that material taking mouth is communicated with in the purity of melt, with the influence of elimination to quality of item.
