Abstract

The invention discloses a supercooling degree prediction method and device. The method comprises the steps that firstly, obtaining the characteristic value of the supercooling degree; then obtaining a supercooling degree prediction model according to evaluation parameters; and finally, inputting the characteristic value of the supercooling degree into a cold degree prediction model so as to enable the cold degree prediction model to output a supercooling degree prediction result. By using the embodiment of the invention, the supercooling degree can be accurately predicted, and accurate data support is provided for nucleation research of the as-cast material.

Description

technical field [0001] The invention relates to the technical field of alloy materials, in particular to a method and device for predicting the degree of supercooling. Background technique [0002] In terms of output and application scale, iron and aluminum are among the most used metals in the world. Iron and aluminum have applications in various industries such as mechanical engineering and shipping. Casting is one of the main methods for the preparation of iron and aluminum materials due to its low cost and wide processing adaptability. The casting process is always accompanied by the nucleation process, which plays an important role in the metal solidification process, and the degree of undercooling has a great influence on the nucleation of the as-cast material, and also controls the phase composition of the as-cast material , organization, performance and quality. Therefore, in the nucleation research of as-cast materials, the degree of supercooling is an essential ...
