Embodiment 1

[0030] Adopt this method to carry out homogeneous fine-grained continuous casting of aluminum alloy: firstly, the casting intermediate alloy containing aluminum alloy grain refiner or alloying elements is made into circular cross-section wire rod; Pulled by the wire feeding / unwinding mechanism 1, it passes through the disturbance driving mechanism 3 and heater 4 of the device shown in the figure; when the temperature of the casting melt in the launder and the preheating temperature of the wire reach the set temperature, the wire end The head 5 quantitatively and continuously invades the casting melt at the launder or draft tube. At the same time, under the control of the disturbance drive mechanism 3, the wire end 5 performs continuous disturbance in the melt, causing the wire uniform dissolution. In particular, the end of the wire can also be used as an agitator to control the temperature (melt liquidus temperature ± 50°C), composition (Al-Ti-B: 0.2wt%-2wt%; rare earth elemen...

Embodiment 2

[0032] Adopt this method to carry out continuous preparation of aluminum-based composite material: at first will contain composite material particle (SiC:1wt%-20wt%; Al 2 o 3 : 1wt%-20wt%) or alloy elements (rare earth elements: 0.2wt%-10wt%) cast aluminum-based master alloy (or made by wrapping composite material particles with aluminum foil, filling and compacting in aluminum tubes, etc. Pre-composite material) is made into a wire rod with a circular cross-section; four coils of wire 2 are respectively drawn by an independent wire feeding / unwinding mechanism 1, and pass through the disturbance driving mechanism 3 and the heater 4 of the device as shown in the figure; When the temperature of the casting melt in the launder and the preheating temperature of the wire reach the set temperature, the wire end 5 is quantitatively and continuously intruded into the casting melt at the launder or the draft tube. Under the control of the mechanism 3, the wire end 5 is continuously di...

Embodiment 3

[0034] This method is used for aluminum alloy homogeneous fine-grained rheological die-casting: firstly, the material containing refiner, alloy elements, and composite material additives is prefabricated into a wire rod with a circular cross-section; a roll of wire 2 is used, and the Under the traction of the wire / unwinding mechanism 1, pass through the disturbance drive mechanism 3 and the heater 4 of the device shown in the figure; 5 penetrates into the melt quantitatively, and at the same time, under the control of the disturbance drive mechanism 3, the wire end 5 is continuously disturbed in the melt, resulting in uniform dissolution of the additive wire. In particular, the end of the wire can also be used as a stirrer to homogenize the temperature and composition of the casting melt in the spoon, so that the alloy elements, refiners, and all solutes of the composite material in the melt can be uniformly dispersed; After stirring for a certain period of time or reaching the ...

Abstract

The invention discloses an efficient pollution-free casting melt homogenous refinement treatment device and method and belongs to the technical field of metal material heat processing. The device is composed of a wire feeding / returning mechanism, an additive wire material or bar material, a disturbance driving mechanism, a heater, a wire material or bar material end head and a melt containing cavity. The additive wire material or bar material is located on the center line of the melt containing cavity. The disturbance driving mechanism is located between the wire feeding / returning mechanism and the wire material or bar material end head. The heater is located between the disturbance driving mechanism and a melt liquid level. The wire material or bar material end head is quantitatively immersed below the melt liquid level. Homogenous refinement treatment is conducted on casting melt through the device, and two melt processing processes, namely additive adding conducted in real time and stirring, are combined into one ingeniously, so that the problem that a stirrer and the melt are interactively polluted is solved; and meanwhile, adding speed of additives is greatly increased. The efficient pollution-free casting melt homogenous refinement treatment device and method have the beneficial effects that self-melting is achieved; zero pollution is achieved; and cleaning is not needed.

Description

technical field [0001] The invention belongs to the technical field of thermal processing of metal materials, and in particular relates to an efficient and pollution-free casting melt homogenizing device and method. Background technique [0002] In some occasions in metallurgy, casting and other industrial fields, it is necessary to add some "additives" (such as alloying elements, refiners, composite materials, etc.) to the cast metal melt, or to apply various "additives" to the cast metal melt. Stirring" (the purpose is to obtain a "homogeneous melt" or "semi-solid slurry" for rheocasting). [0003] Generally, the addition of additives in the casting melt is done once in advance in the smelting and holding furnace. Due to the large amount of alloy melt and the long waiting time for casting, problems such as component segregation and additive effect degradation are prone to occur. The "wire feeding" technology, which is a typical representative of the "real-time" adding me...
