Description

Technical Field

[0001] The invention relates to the technical field of cooling the samarium alloy smelting ingot, and in particular to a device and method for rapidly condensing the samarium alloy smelting ingot. Background Art

[0002] In the smelting process of samarium metal, controlling the uniformity of alloy components and preventing the volatilization of elements are the keys to improving product quality. In an environment of 964℃, the metal vapor pressure of samarium metal is 133Pa, and the evaporation rate reaches 83g / (cm 2 h). During the smelting process of samarium iron and samarium copper alloys, when entering the high temperature stage, the evaporation rate of metal samarium increases significantly, which will cause the samarium content in the alloy to decrease, thus affecting the overall performance and quality of the alloy.

[0003] Traditional cooling methods usually cannot meet the needs of rapid condensation, which leads to the volatilization of alloy elements and uneven composition, which in turn affects the cooling efficiency. Due to insufficient cooling speed, alloy components are prone to segregation during solidification, resulting in uneven composition inside the ingot, which affects the performance of the final product. Traditional cooling equipment is often bulky and complicated to operate, which is not conducive to rapid switching and adjustment on the production line, thereby reducing production efficiency. During the cooling process, improper temperature gradient control can easily form a hard shell on the surface of the ingot, while the contraction of the internal liquid metal will generate stress and cause cracks. Traditional cooling technology often cannot achieve precise control of the cooling process, making it difficult to ensure the dimensional accuracy and surface quality of the final product. Due to the lack of effective cooling control, energy consumption is high, production costs are high, and the impact on the environment is large.
