Introduction
In-depth interpretation of the technical specifications for heat treatment process simulation of large steel forgings
1. Background and significance of standard formulation
With the increasing demand for heavy equipment in industries such as energy, metallurgy and transportation, large steel forgings are increasingly used in key projects. However, the complexity and high requirements of their heat treatment process make it difficult for traditional experience-based methods to meet modern production needs.
The application of numerical simulation and physical simulation technology has become the key to solving this problem. By combining computer-aided engineering (CAE) technology and experimental verification, precise control of the heat treatment process can be achieved to ensure the quality and performance of large steel forgings.2. Basic process of heat treatment process simulation
| Basic process | Main content | Specification requirements |
|---|---|---|
| Pre-processing of numerical simulation | Establish 3D model, divide grid, and set material parameters | The degree of grid refinement must meet the accuracy requirements; material performance parameters must be based on experimental data |
| Solution and calculation | Solve temperature field, organizational field and stress field | Use efficient thread allocation to ensure calculation stability |
| Post-processing and result analysis | Visualize simulation results and extract key data | Output temperature curve, tissue distribution diagram and stress cloud diagram |
3. Comparative analysis of standard framework
Based on GB/T 37586-2019, we conducted a dimensional analysis of the technical specifications for heat treatment process simulation, as shown in the following table:
| Dimensions | Standard requirements | Implementation suggestions |
|---|---|---|
| Meshing | The mesh needs to be refined in areas with drastic temperature changes; hexahedral elements are preferred | Use adaptive meshing technology to optimize calculation efficiency |
| Material property setting | Including thermophysical properties, mechanical properties and phase change parameters | Material model calibration based on experimental data |
| Boundary condition setting | Heat transfer coefficient combined with ambient temperature; displacement and contact boundary conditions are clear | Verify mesh independence through comparative calculations |
4. Implementation recommendations and best practices
To ensure the effectiveness and reliability of heat treatment process simulation, we propose the following implementation recommendations:
- Before conducting numerical simulation, the applicability of the simulation tool should be verified through benchmark experiments.
- In physical simulation experiments, it is necessary to ensure the consistency of materials and processes between the specimen and large forgings.
- It is recommended to use multi-field coupling simulation technology to comprehensively evaluate the effects of temperature, structure and stress.
- In actual production, the heat treatment process parameters should be optimized in combination with the numerical simulation results.
