Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with accompanying drawing:

[0021] like Figures 1 to 2 As shown, the multifunctional agitator integrating melt purification and stirring in this embodiment includes a main shaft 1, and the main shaft 1 is provided with a plurality of sleeves in the longitudinal direction, and at least one is provided on the outer wall of each sleeve. A stirring rod 3, the stirring rod 3 has a shell structure, and a plurality of through holes 3a are densely covered on the shell surface of the stirring rod 3, and the inside of the shell of the stirring rod 3 is filled with a melt purification flux 4.

[0022] The principle of purifying the melt of the multi-function stirrer of the present invention is: under the action of stirring force, inclusions and air bubbles in the melt quickly pass through the porous shell of the stirring rod and fully contact with the purified flux to undergo adsorption and chemical reaction....

Abstract

The invention belongs to the field of metallurgical equipment, and particularly discloses a multifunctional stirrer with integrated melt purification and stirring. The multifunctional stirrer comprises a main shaft, wherein a plurality of shaft sleeves are longitudinally arranged on the main shaft; at least one stirring rod is arranged on each shaft sleeve; the stirring rods are of shell structures; a plurality of through holes are densely formed in the surfaces of the shells of the stirring rods; the shells of the stirring rods are filled with a melt purification fusing agent. A solvent method and a stirrer used in a melt purification method are effectively combined, a gas and impurity removing effect which is achieved through a fusing agent method and an air blowing method together is achieved by using a stirring method on the premise that the cost of alloy smelting is lowered and impurities are expelled, and the cleanness of alloy melt is greatly improved.

Description

technical field [0001] The invention relates to metallurgical equipment, in particular to a multifunctional stirrer integrating melt purification and stirring. Background technique [0002] Generally, the design of the stirrer used for alloy smelting mainly focuses on the improvement of the shape of the stirrer and the simplicity and convenience of the manufacture, cleaning and replacement of the stirrer. The former mainly increases the contact area with the melt and improves the uniformity of stirring. The latter focuses on the issues of cost and efficiency. As we all know, the introduction of the stirrer is to improve the uniformity of the composition of the alloy melt, thereby improving the quality of the alloy casting. However, in the alloy smelting process, not only the uniformity of the melt composition must be considered, but also the inclusions and gases in the melt should be purified. The purification methods of alloy melts are divided into two categories: adsorpt...
