1. The material is CL60, and its melting chemical composition shall comply with the provisions of TB / t2817. The heat treatment status of wheels is overall quenching and tempering treatment after forging, and the tread and rim are quenched + tempered. The batch principle is wheels with the same melting furnace number, the same model and the same heat treatment status. The hardness value of tread and rim surface is required to be 300 ~ 380hb, the hardness is distributed in steps, and the hardness at 20mm below the tread is not less than 260hb. After heat treatment, the surface hardness of each wheel shall be uniformly tested at three points on the tread to meet the drawing requirements confirmed by both parties.
2. The wheels are required to be forgings, which shall meet the corresponding requirements of JB / t5000.8-2007, and the quality grade of forgings is class III. Forgings shall be free from surface defects, such as cracks, indentations, joints and any other defects that can affect product quality.
3. The wheel shall be free of cracks, the tread and rim shall be free of defects affecting the service performance, and the defects shall not be repaired by welding.
4. In order to ensure the product quality, 100% ut NDT shall be conducted for the whole wheel, and 100% MT inspection shall be conducted for the wheel tread and rim. The flaw detection method and results shall meet the class II quality requirements of JB / t5000.15-2007.
5. The performance test of raw material test bar shall be conducted for each furnace of raw materials, and the test results shall comply with the provisions in Table 1.
