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.

Normal temperature tensile specimens with d0 = 10mm and l0 = 50mm shall be used The U-shaped 2mm groove depth normal temperature impact specimen is adopted
Test method GB / T 228 Test method GB / T 229
Note: the specification of raw material test bar is Ф thirty × 400mm, the heat treatment state is normalizing after forging + quenching and tempering treatment.
6. For each heat of raw materials, a high-power sample shall be taken from the forging test bar of raw materials according to the requirements of GB / t10561 for non-metallic inclusion evaluation, and the results shall comply with the provisions of Table 2. The inspection surface shall be a longitudinal section passing through the axis of the test bar, with an area of about 200mm2 (L) × B:20mm × 10mm).

7. The wheel tread shall be marked with paint "furnace code + billet number + drawing number"; "Furnace code + billet number" shall be printed on the rim end face with steel seal, and the word height shall be 10mm.
8. There are complete forging manufacturing process procedures, heat treatment process procedures and complete quality control system to ensure product quality.
9. Accept the supervision personnel appointed by the buyer to inspect the products. The inspection is based on the requirements of the contract, standard specifications and this technical specification, and provide the self inspection inspection certificate, test report, etc. The finished delivered wheels provided shall be subject to anti rust treatment. The hub holes and threaded holes shall be coated with butter and oil paper for anti rust treatment, and all other surfaces shall be coated with black paint.
