Abstract
The present invention is undercurrent type passage mechanism for magnesium alloy melt converter and belongs to the field of metal material processing technology and metallurgical technology. The undercurrent type passage mechanism includes undercurrent passage for magnesium alloy melt to flow through, cooling water jacket with water inlet and water outlet separately on two ends, induction heating coil around the water jacket, resistance wires embedded inside annular silicon carbide furnace body around the undercurrent passage, heat insulating material outside the silicon carbide furnace body, and support. The present invention has simple operation, convenient control, fast response and the undercurrent passage made of stainless steel to avoid contamination on magnesium alloy melt.
Description
Technical field
What the present invention relates to is the equipment in a kind of alloy technology field, specifically is a kind of undercurrent type passage mechanism that is used for magnesium alloy melt converter.
Background technology
Along with the fast development of China's aerospace, car industry, the lightweight of the vehicles such as spacecraft and automobile just becomes eternal pursuit.Magnesium alloy has high specific strength, specific stiffness, than elastic feel quantity, become the focus that material supplier author pays close attention to day by day.The quality of magnesium alloy fused mass is the basic and crucial of Mg alloy castings or deformable member.In former magnesium fusion process or casting process; usually need to adopt suitable mode that the magnesium melt is forwarded to the holding furnace from smelting furnace; the melting furnace that verts of industrial general employing is now directly poured melt into holding furnace; because magnesium and melt chemical property thereof are very active; in toppling process; oxidizing fire and air-breathing takes place easily, worsens the quality of melt.So people begin to attempt adopting with the isolated pattern melt transmission of air, such as adopting method transmission magnesium alloy fused mass such as electromagnetic pump and mechanical pump.
Find through literature search prior art, Chinese patent application number 01218800, (publication number CN2476374Y), name is called: a kind of magnesium alloy low-pressure casting system of electromagnetic pump low-pressure casting, this technological invention a kind of magnesium alloy low-pressure casting system of electromagnetic pump low-pressure casting, comprise Mg alloy smelting furnace, gas mixing device, melt transmitting device, workbench and support, holding furnace and electromagnetic pump, power supply and control system.This system as filling the type device, and casts foundry goods from being melted to of magnesium with electromagnetic pump, melt all be in airtight and protective atmosphere in; avoided the burning of magnesium effectively; alleviate the oxidation of magnesium, thereby improved the quality of magnesium foundry goods, be applicable to the low pressure casting of magnesium alloy.But this invention electromagnetic pump is the same with mechanical pump, and the easy corrosion and damage pump housing of magnesium alloy fused mass element, high temperature maintenance difficulty and efficiency of transmission are low, and melt enters static holding furnace from top to down, and melt rolls and causes oxidation and air-breathing.
Summary of the invention
The present invention is directed to the deficiency of existing magnesium alloy fused mass transmission converter technology, a kind of undercurrent type passage mechanism that is used for magnesium alloy melt converter is provided.Mechanism of the present invention adopts undercurrent type passage mechanism to be communicated with the purpose that reaches the transmission magnesium alloy fused mass in the middle and lower part of Mg alloy smelting furnace and static stove, and has solved disadvantages of background technology based on law of connected vessels.
The present invention is achieved through the following technical solutions, and comprising: undercurrent type passage, cooling jacket, load coil, resistance wire, carborundum body of heater, insulation material and support.Undercurrent type passage is the circular channel that magnesium alloy fused mass is flowed through, and two ends can be communicated with Mg alloy smelting furnace and the welding of static stove.The undercurrent type passage middle part is welded with cooling jacket, is divided into circular interior cover and ring-shaped jacket, and interior cover communicates with undercurrent type passage, and in order to the magnesium alloy fused mass of flowing through, dimensions is consistent with undercurrent type passage; Overcoat is in order to logical cooling water, and two ends are furnished with water inlet and delivery port.The toroidal inductive heater coil is fixed on outside the cooling jacket by support, utilizes extraneous intermediate frequency power supply to power in order to produce induction heat for it.Undercurrent type passage is provided with resistance wire and insulation material outward, and resistance wire is embedded in the annular carborundum body of heater hollow hole, outer boundary power supply power supply heating, and insulation material becomes entangled in external of silicon carbide furnace by asbestos yarn.
When at the smelting furnace molten alloy, pass to cooling water to cooling jacket, the magnesium alloy fused mass in allowing in the cover solidifies, blocking-up smelting furnace and static stove; After the alloy liquid in the smelting furnace refines, stop logical cooling water, pass to electric current of intermediate frequency to load coil, its interior magnesium alloy of heating cooling water sleeve, conducting smelting furnace and static stove behind the alloy melting, alloy liquid can successfully flow into static stove.Resistance wire that undercurrent type passage is provided with outward and insulation material mainly are to guarantee that the magnesium alloy in the undercurrent type passage remains liquid.
The present invention has substantive distinguishing features and marked improvement, liquid magnesium alloy flows in undercurrent type passage all the time, do not contact with air, stop the melt quality deterioration that magnesium alloy fused mass oxidation and burning bring, adopted electromagnetic induction heating, simple to operate, control is convenient, time response is fast, and whole channel material adopts stainless steel entirely, prevents contamination on magnesium alloy melt.

The specific embodiment
As shown in Figure 1, the present invention includes undercurrent type passage 1, carborundum body of heater 2, resistance wire 3, cooling jacket 6, load coil 5, insulation material 8 and support 9.
Undercurrent type passage 1 usefulness stainless steel tube processes, internal diameter 50mm, and wall thickness 10mm, two ends are communicated with the crucible of smelting furnace and static stove, and length is determined according to the distance of smelting furnace and static stove.
Annular carborundum body of heater 2 is fixed on outside the undercurrent type passage 1 by approaching plain modes such as iron hoop or thin wire, inlays resistance wire 3 in the hollow hole, by extraneous power supply power supply heating, power requirement 5KW/m; The thickness of insulation material 8 is about 50mm, becomes entangled in carborundum body of heater 2 outsides by asbestos yarn.Guarantee melt temperature in the undercurrent type passage 1 more than liquidus temperature, thereby guarantee the flowability of alloy liquid.
The present invention is suitable for the converter transmission of magnesium alloy fused mass, also is fit to other easy oxidation or the converter transmission of alloy liquid that melt quality is had relatively high expectations.
