Quenching and tempering heat treatment of the surface of the three-dimensional flexible welding platform for casting castings

The quenching and tempering heat treatment of the surface of cast iron platforms is usually carried out by induction heating or flame heating. The technical parameters of SHOUYAO include external hardness, partial hardness, and effective hardening layer SHENDU. Hardness testing can be conducted using a Vickers hardness tester, as well as a Rockwell or external Rockwell hardness tester. The selection of experimental force (ruler) is related to the effective hardening layer depth SHENDU and the surface hardness of the workpiece. This involves three types of hardness testers.

The Vickers hardness tester is an important method for checking the surface hardness of heat-treated workpieces. The three-dimensional flexible welding platform can use an experimental force of 0.5-100kg to check the surface hardening layer as thin as 0.05mm. Its accuracy is __, and it can distinguish fine abnormalities in the surface hardness of heat-treated workpieces. In addition, the presence of a hardening layer SHENDU also needs to be tested by a Vickers hardness tester. Therefore, for units that perform surface heat treatment processing or use surface heat treated workpieces, there is a BIYAO welding platform manufacturer that equips a cast iron flat plate with a Vickers hardness tester.

The external Rockwell hardness tester is also very suitable for checking the hardness of quenched workpieces. There are three types of scales to choose from for the external Rockwell hardness tester. It can inspect various surface hardened workpieces with hardened SHENDU spanning 0.1mm. Of course, the accuracy of the Rockwell hardness tester on the surface is not as high as that of the Vickers hardness tester, but as a testing method for quality management and qualification inspection in heat treatment factories, it can meet the requirements in the early years. The three-dimensional flexible welding fixture platform not only has the characteristics of simple operation, easy use, low value, flexible measurement, and direct reading of hardness values, but also uses a surface fitter flat Rockwell hardness tester to perform rapid and non-destructive piece by piece testing on batches of surface heat-treated workpieces. This is of great significance for metal processing and mechanical manufacturing factories.

When the surface heat treatment hardening layer is thick, a Rockwell hardness tester can also be used. When the heat treatment hardening layer thickness of the three-dimensional flexible welded flat plate is between 0.4-0.8mm, the HRA ruler can be used. When the hardening layer thickness spans 0.8mm, the HRC ruler can be used.

The three hardness values of Vickers, Rockwell, and external Rockwell can be easily converted into hardness values that meet specifications, drawings, or user requirements. The corresponding conversion tables have been provided in the world standard ISO, the American standard ASTM for two-dimensional flexible welding platform manufacturers, and the Chinese standard GB/T.
