Abstract: In response to the process characteristics of multi-parameter variables in heat treatment, aviation aluminum alloy material type and heat treatment process type were selected as variables, and a multi condition judgment rule was adopted to construct an integrated management and control knowledge base for aluminum alloy heat treatment. The temperature rise, holding, cooling, and quenching parameters during the aluminum alloy heat treatment process were digitized, and the integration of heat treatment control process knowledge base in the heat treatment information control system and directly interfaces with other information systems such as MES in the workshop were achieved. It automatically retrieves data-driven process parameters and completes distribution, promoting the direct control of the heat treatment information control system over the process of heat treatment equipment. This has theoretical and practical significance for promoting the informatization, integration, quality monitoring, and process management of special heat treatment process production.
