This standard specifies the evaluation method for macrostructure defects in the full cross-section of rolled steel integral wheels for railway use.<\/p>\n

1. Scope<\/h2>\n

This standard applies to the evaluation of macrostructure defects in rolled steel integral wheels used in railway applications.<\/p>\n

2. Reference Standards<\/h2>\n

This standard references relevant Chinese railway industry standards for wheel manufacturing and quality inspection.<\/p>\n

3. Macrostructure Defect Types<\/h2>\n

The standard defines various types of macrostructure defects that may occur in railway wheels, including segregation, porosity, and inclusions.<\/p>\n

4. Evaluation Method<\/h2>\n

The evaluation is performed on the full cross-section of the wheel using low-magnification examination techniques.<\/p>\n\n
