Description
Technical field
What the present invention relates to is a kind of melt treatment device, and particularly a kind of molten metals mixer belongs to casting field.
Background technology
In metal products and starting material manufacturer, adopt the solidified structure of the whole bag of tricks fining metal to become the necessary link of producing the high-test metal material.The refinement technology of solidified structures such as traditional interpolation fining agent (fused salt or alloy), mechanical vibration, electromagnetism or ultrasonic agitation exists easy contaminated melt and environment, alloying constituent is had than shortcomings such as strong selectivities, and thinning effect, reliability aspect all have much room for improvement.In recent years, come the technology of thinning solidification structure to obtain extensive studies by processing to melt, find by literature search, author Geng Haoran etc. are at " China YouSe Acta Metallurgica Sinica " 1994,4 (supplementary issues), the last published article of P149, name are called " Temperature Treatment of ZA 27 alloy melt is to tissue and Effect on Performance ", and this article utilization adds the technology of the similar metal fragment refinement of Quench aluminium zinc tissue.This scheme is added in the middle of the metal melt after needing earlier the alloy part Quench to be solidified and being pulverized, though can realize the refinement of metal solidification texture, not only easily brings a large amount of oxide inclusions into metal fragment, and be not suitable for scale operation.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of molten metals mixer is provided, this device utilizes high low temperature metal melt phase blended method, realized the purpose of fining metal tissue, the present invention need not add foreign matter to metal melt, neither can pollute alloy, also not pollute the environment; Its thinning effect is to the metal ingredient no dependence, as long as control temperature, hybrid mode and the melt quality ratio of melt well, just the solidified structure of fining metal effectively is applicable to ferrous metal and non-ferrous metal, as iron and steel, aluminium, magnesium and alloy thereof.The present invention is made up of Metal Melting holding furnace, low-temperature melt treatment system, high-temperature fusant treatment system and melt-mixing filtering system, the high-temperature fusant treatment system is positioned at the below of Metal Melting holding furnace, link with the holding furnace outlet, the low-temperature melt treatment system is positioned at the below of Metal Melting holding furnace, link with the holding furnace outlet, melt-mixing filtering system top is connected with freezer compartment with high-temperature chamber with closed conduit by closed conduit, and lower part outlet is connected with Melt launder.
The low-temperature melt treatment system mainly comprises flow control magnetic valve, closed conduit, freezer compartment and magnetic stirrer.The outside magnetic stirrer that surrounds of freezer compartment, magnetic stirrer is formed by the coiling of water-cooled copper ruhmkorff coil.The freezer compartment rear portion links by closed conduit and mixing section.Closed conduit and the used refractory materials of low temperature locular wall have heat-shock resistance preferably, are difficult for during use cracking, and also have collapsibility preferably simultaneously, change behind the life-time service and can be used as material of construction through break process, and be little to the pollution of environment.The metal melt of this system that flows through is under the effect of water coolant, temperature is reduced to temperature required rapidly, under the effect of the induction stirring shearing force that ruhmkorff coil provided, the column crystal that hinders melt flow is suppressed generation, thereby guarantees that low-temperature melt has certain fluidity simultaneously.Metal melt promptly becomes low temperature liquid metal or semi-solid-state metal through after this system, enters mixing section subsequently.
The high-temperature fusant treatment system mainly comprises flow control magnetic valve, closed conduit, high-temperature chamber and induction heater, and the body of heater of Metal Melting holding furnace is that flame retardant coating, insulating and steel casing are formed, and the smelting furnace profile is a rectangular parallelepiped.High-temperature chamber links to each other with closed conduit, the outside load coil that surrounds, and load coil forms for the water-cooled copper coiling.The high-temperature chamber rear portion links by closed conduit and mixing section.The used refractory materials of closed conduit and high-temperature chamber all has heat-shock resistance preferably, is difficult for during use cracking, and also has collapsibility preferably, life-time service to change simultaneously after can be used as material of construction after the break process, and is little to the pollution of environment.Metal melt promptly becomes high temperature fluent metal through after this system, enters mixing section subsequently.
The melt-mixing filtering system is made up of flame retardant coating, insulating and steel casing, be rectangular-shaped, the multiply that interior raising temperature refractory materials is made through sintering is intersected snakelike hybrid channel, in the bottom of hybrid channel is the two-stage filtration plate, wherein first step screen plate contacts with the hybrid channel, be positioned at the middle and lower part of mixing section, its specification is 10～20ppi; Second stage screen plate is positioned at the bottom of mixing section, and specification is 30ppi.The two-stage filtration plate is foamed ceramics and makes.Chute is that high-temperature refractory is made, and the outside is surrounded by steel shell, is connected as a single entity with mixing section.High low-temperature melt enters thorough mixing after the melt-mixing filtering system, and enters ingot mould or crystallizer by chute behind the system purification after filtration.
Metal melt in the Metal Melting holding furnace is by outlet, import high-temperature chamber and freezer compartment respectively through the flow control magnetic valve, melt through high-temperature chamber becomes the hyperthermia and superheating metal melt, metal melt through freezer compartment becomes low temperature liquid metal or the semi-solid-state metal with better flowability, this two portions metal melt enters the melt-mixing filtering system through closed conduct, and realize therein mixing, purify the back more after filtration and flow out.Can make the flow rate control of melt in the high-temperature chamber by the adjusting flow solenoid valve is 10-20mm/s, and the used power frequency of well heater is 10-50kHz, and the residence time of melt in high-temperature chamber is 10-40s, and temperature rise can reach 300 ℃ at most.Making the flow rate control of melt in the freezer compartment by the adjusting flow solenoid valve is 10-20mm/s, and the used power frequency of water-cooled electromagnetic stirring system is 3-20Hz, and the residence time of melt in freezer compartment is 15-60s, and the cooling extent of melt can reach 200 ℃ at most.The melt-mixing filtering system is made with refractory thermal insulating material, in establish special-purpose hybrid channel, to realize the mixing rapidly and efficiently of high low-temperature melt.Also be provided with the two-stage filtration plate in the melt-mixing filtering system, can guarantee that nonmetal inclusion is removed basically in the melt, obtain clean pre-crystallized mixed melt.
The present invention has substantive distinguishing features and marked improvement, is not adding any fining agent, not under the condition by any other thinning processing technology, can obtain complete non-dendritic solidification tissue in metal mold, and its grain-size can be controlled in 70 microns.
