Thermal treatment technology knowledge pushing method based on material component similarity

Abstract

The invention provides a thermal treatment technology knowledge pushing method based on material component similarity. The method comprises the steps of inputting standard data of element chemical component contents of various metal materials related to thermal treatment and building a data main table and a data subsidiary table; accumulating and recording actual measurement data of the element chemical component contents of the metal materials in each batch and building a data main table and a data subsidiary table; accumulating and recording actual measurement data of technological parameters of a technological method, temperature, time, vacuum degree and the like during thermal treatment on the metal materials in each batch; accumulating and recording data of thermal treatment performance and mechanical performance during thermal treatment on the metal materials in each batch; according to each piece of the recorded actual measurement data of the element chemical component contentsof the metal materials, calculating the similarity index of each material; utilizing the similarity indexes of the materials and pushing thermal treatment knowledge through similarity retrieval. Thermal treatment data is accumulated and emphasized, the dependence on experience of field operating personnel is reduced, and the efficiency and quality of technological design are improved.

Description

Technical field [0001] The present invention relates to the technical field of digital manufacturing, in particular to a method for pushing heat treatment process knowledge based on the similarity of material components. Background technique [0002] At present, at the heat treatment production site, the ability and means to automatically collect heat treatment process parameters are already available, and there is an urgent need to realize the accumulation and reuse of collected data through the knowledge base. [0003] The heat treatment process design is usually based on empirical process design, especially the heat treatment process parameters such as temperature, which are often prescribed relatively broadly, without considering the actual batch differences in the material's chemical composition content, etc., There are deficiencies in capacity. [0004] Establishing a knowledge base by integrating data such as heat treatment measured process parameters, material element chemic...
