Description
Technical Field
The utility model relates to an aluminum liquid online refining device used before continuous and semi-continuous casting of aluminum billets.
Background
At present, when aluminum blanks with higher casting quality requirements are cast at home and abroad, an online refining device is required to be arranged on a flow channel in front of a casting machine, and the online refining device is used for performing online degassing, deslagging and other purification treatments on molten aluminum and sometimes has the functions of adding, stirring, filtering, heating, preserving heat and the like of a grain refiner. At present, the aluminum liquid on-line refining device commonly used at home and abroad has the following two types: one is a graphite rotor type on-line refining device, such as chinese patent 201310518883.0, which utilizes the rotation of one or more graphite rotors in the aluminum liquid to break the high purity nitrogen (argon) gas injected from the graphite rotors, increase the number of bubbles, enlarge the bubble action area, prolong the residence time of bubbles in the aluminum liquid, and at the same time, the graphite rotors can effectively stir the aluminum liquid to increase the uniformity of the grain refiner, and the device adopts insertion or silicon carbon rod heating. The refining device has good refining effect, the dehydrogenation rate is generally more than or equal to 50%, and the dehydrogenation rate is improved when the number of the graphite rotors is increased. However, the following disadvantages exist: a. The running cost is high: the consumption of the graphite rotor and the plug-in silicon carbide rod is larger, the consumption is increased when the number of the graphite rotor is increased, and the power consumption is also increased. b. The structure is more complicated, and the equipment investment is larger. c. The refining effect is hardly further improved.
And the other is a gas brick type online refining device, for example, in the Chinese patent 201420618086.X, the gas brick with the micropores arranged at the bottom of the degassing box is used for penetrating the natural rising of the small bubbles, the refining is carried out by electromagnetic stirring, and the rising process of the dispersed bubbles can have a little stirring effect on the molten aluminum. b, low operation cost: the consumption of the graphite rotor and the power consumption of a driving system are avoided. However, the following disadvantages exist: a. the refining effect is poor: because the electromagnetic stirring is matched with the circular cavity, the dispersed bubbles and the aluminum liquid are easy to form a continuous rotational flow, the bubbles are large in size, the bubbles which are dispersed and rise are combined, the bubble retention time is short, and the hydrogen removal rate is only 30-40%. b. Poor stirring effect: the grain refiner, the chemical components of the aluminum liquid and the temperature uniformity are poor. For example, in the Chinese patent 200620050898.4, the small bubbles are naturally raised by permeating the microporous air bricks arranged at the bottom of the degassing box, electromagnetic stirring is used for refining, the dispersion bubble raising process has a little stirring effect on the aluminum liquid, and radiation type heating is performed. b. The operation cost is low: the consumption of the graphite rotor and the power consumption of a driving system are avoided. c. The heating system has low manufacturing cost, no occupation and low control system cost. However, the following disadvantages exist: a. the refining effect is poor: because the electromagnetic stirring is matched with the circular cavity, the dispersed bubbles and the aluminum liquid are easy to form a continuous rotational flow, the bubbles are large in size, the bubbles which are dispersed and rise are combined, the bubble retention time is short, and the hydrogen removal rate is only 30-40%. b. Poor stirring effect: the grain refiner, the chemical components of the aluminum liquid and the temperature uniformity are poor. c. Poor heating effect: the surface of the produced molten aluminum is generally formed into films and slag, and the molten aluminum has a certain depth indoors, so that the heat of the spoke body cannot be transferred in time, and the heat lost due to impurity removal of inert gas cannot be almost compensated, and the control difficulty of the subsequent process is increased. d. The quenching and sudden heating of each part of the box body are obvious: because no slag removing port is arranged, the cover must be opened to remove slag after a period of production, so that the material in the box body is rapidly cooled and heated at the temperature to influence the service life.
