Problems solved by technology

To improve the quality of the melt, the mechanical stirring method is simple and easy, but there is a dead zone of stirring, which affects the uniformity of the melt. Ultrasonic treatment of the metal melt can refine the solidified grains of the metal and promote the formation of gas bubbles in the metal melt. And grow up and float, can promote the agglomeration of inclusions, and then float up, and some studies believe that the inclusions can be broken to achieve dispersion distribution, all of which help to improve the quality of metal melt
[0003] The existing research method is mainly to immerse the ultrasonic tool head in the metal melt to be treated for ultrasonic treatment, but when this method is used to process high melting point metals (such as steel melt), the high temperature resistance and corrosion resistance of the ultrasonic tool head are r

Abstract

The invention discloses compound smelting equipment ultrasonically stirring low-melting-point alloy, which is applicable for the smelting and preparation of the low-melting-point alloy, in particular to various tin-bismuth series alloy at the low melting point of below 300 DEG C. The equipment comprises a crucible, a heat-preservation and heating device, a temperature control device, an ultrasonic stirring device, an ultrasonic wave generation and control device and a mechanical stirring device, wherein molten metal is put in the crucible. The equipment is simple in structure and practical; the mechanical stirring device and the ultrasonic stirring device are mutually perpendicular without intervention; ultrasonic waves are imported to the molten metal from the side of the crucible; the efficiency is high, the ultrasonic energy loss is low, and moreover, the solid rate of the molten metal is higher; even when metal stirring fails, the ultrasonic waves still can be applied till metal solidification; through the compound ultrasonic and mechanical stirring, grains can be refined, so that a non-dendritic structure is obtained; homogenizing of the ingredients and the temperature of the fused molten metal is sped up; the plasticity of prepared alloy is improved greatly in comparison with the plasticity of alloy prepared by a traditional method.

Description

technical field [0001] The invention belongs to the technical field of metal preparation, and in particular relates to a low-melting-point alloy ultrasonic stirring composite melting equipment, which is suitable for smelting and preparing low-melting-point alloys below 300°C, especially various tin-bismuth alloys. Background technique [0002] The quality of metal products such as ingots, castings, and continuous casting products is directly determined by the quality of the smelting process and the metal melt. The control level of gases and inclusions in the melt is an important response to the purity of the metal melt. With the continuous development of smelting and equipment technology, the purity of metal melt has been greatly improved, and the inclusion level and gas content have been reduced, but the problem still exists. To improve the quality of the melt, the mechanical stirring method is simple and easy, but there is a dead zone of stirring, which affects the unifor...
