Description

TECHNICAL FIELD

[0001] The utility model relates to high temperature alloy material manufacturing technical field, concretely relates to a kind of industrial high-efficiency mass production high-purity fine-grained high-temperature alloy's device. BACKGROUND

[0002] In the field of industrial mass production of high-temperature alloy master alloy, the melting device and process scheme play a decisive role in the key parameter indicators of the material, such as oxygen and nitrogen content, density and defect occurrence rate. With the continuous iteration and update of process equipment, the problems of macrosegregation and coarse grains existing in traditional industrial ingot casting are more and more prominent in new type die forging, wire drawing process and advanced technology such as fast melting casting, leading to more defects such as cracking. Therefore, there are relatively few mass production applications in the industry that can effectively solve these problems.

[0003] Current technical improvements are mostly focused on the optimization of experimental furnaces, such as improving alloy organization by inserting ultrasonic devices at the casting liquid surface. Studies have shown that the use of ultrasonic treatment can significantly change the solidification process of the alloy, refine the grains and improve the grain morphology, thereby greatly improving the alloy performance. However, current research is mostly limited to the single direction application of ultrasonic waves in experimental furnaces, while industrial mass production equipment usually adopts the method of directly casting to the mold after melting, lacking intermediate processing steps. The casting temperature of industrial mass production furnace is much higher than that of experimental furnace, resulting in serious rod head burning and hot erosion when the ultrasonic tool head directly contacts the alloy liquid, making it difficult to maintain stable operating conditions and not suitable for industrial mass production applications. And ultrasonic treatment is only carried out before flowing into the mold pipe, while the time from the molten state to the solidification in the mold pipe is relatively long, which reduces the gain effect of ultrasonic treatment and limits the nucleation, cracking and feeding effect during alloy solidification.
